I’m a student attending Wyotech right now training to become a diesel tech, and I find these videos very refreshing and assuring that what I’m learning in class is what I will actually be doing, and that I’m not being told bullshit by someone that just wants my money
Another great video. I don't work on big engines like those but, as a long time wrench person, I really love how you go about diagnosing stuff and fixing the issues. It's very obvious you know what you're doing. Stay safe, and keep up the great work. Jim
I know you have a life and do this as a side gig. But you are hands down the leading authority on these CAT power plants and I sure wish you posted more and longer videos. Until then, I'll take anything you put out there. Cheers
your videos are great. I'm an off road tech who works on cats and when I was an apprentice in school my teacher would pull up your videos sometimes. that c32 was probably out of a 777. thanks
Why dislike this video? Good find...really bugs me to see the results of incompetence. People are supposed to be professional. They sure get paid enough.
I've run a lot of trucks in big fleets with those 3 position jake switches like the one you found. I'm not certain it is abnormal, I think that's how Kenworth Peterbilt and Freightliner have them configured from the switch manufacturer. It's weird but I've seen that on hundreds of trucks.
because there is someone who is competent is his field not only showing vehicle repairs but teaching newbies how and why diesels work. The destruction of the week always comes back to the lack of maintenance, mechanic error or parts failure. Got a voice like Mike Rowe that gives you confidence in his ability.
Had the same issue in our shop on an isx cm870, multiple techs/engine harness, injector harness, jake switches and even a turbo later, popped the valve cover and found the jakes just needed rebuilded because the orings were cut and hard as a rock, remember the KISS method
I have an three different trucks with three different engines that all have the jake selector switch set like that. One even has factory labeling showing it as such. I assumed they were all like that, but always thought it was weird.
Nice video. It amazes me how many times I've heard "my jakes stopped working", my first reply, "check the oil lately?" You'd be shocked how many times 2-3 GALLONS of oil fixes the problem. *facepalm* some drivers.
your comment is a face pal. you dont know anything about diesels with jakes. It can be low as anything. If there is enough oil pressure to register the gauge, tan the jakes wll work as normal. BEing 2-3 gallons low on a 10 quart capicity wont hinde anything. You are full of crap.
I have c15 acert TT 06 379. Weak engine brake. Switch works good replaced seloinods and replaced wiring. Also replaced O rings and springs inside engine brake rails. had overhead done. Still same thing. My turbos got over 700k on them. Can turbos be the issue? Not much. Shaft play. But I have noticed the spool sound isn't the same.
Maybe you can help! Swapped from a DD4 to 5EK with a Kustom Truck harness. Jakes came with 5ek engine. Were functioning sporadically. Checked adj twice. Replaced all 3 solenoids. Cured for a bit but didn't feel like they were working well. Now it's back to sporadic operation 🤷♂️
Hi buddy, jakes of my wester star 2022 are soo weak ... Company could'nt figure out what the problem is wasted my time and money. They changed the solenoids injector rocker arm and reprogram it but nothing better
interesting find on the jakes, had a issue similar on a m-11 Cummins, someone had over tightened the rocker arm support shaft, and cracked the support that holds the rocker arm shaft, the m-11s are kind of weird with their valvetrain, and the #6 valves were not sitting straight, and this caused the #6 Jake piston to bend and bind in its bore and get stick in the up position. took a few minutes to figure that one out lol.

I'm not sure why they use that insert design instead of just keeping the exhaust port a uniform size. The head is machined to fit them though and they match the exhaust manifold sizes. I'm sure some engineer thought it was a good idea for some reason and perhaps there is a very good reason that I'm unaware of.
Yes it's was 2ws. I replaced the shaft and rockers for the one shaft. They weren't as bad as you would think. The customer said it ran like that for 2 years. I also installed the updated hold bolts.
patrick hallyburton I agree to a certain extent, at one time we all knew nothing but we all had to learn, the thing is learning the proper way and what I have found to be very difficult nowadays is a lot of companies do not want to give out any information because they want to make sure that they can get the money themselves. That’s why I am very thankful that there are individuals out there willing to share their knowledge. Thank you
@@jeffsimonar7161 to an extent, if you are way out of your league its better to leave it to someone else. 99 times out of 100 i see people cause themselves more money lost because they feel that they can just "figure it out" when they dont understand the basics. i see people take a 200$ problem and turn it into a 3000$ problem very quickly. that being said there is lots of stuff that can be easily taught and done with little training, its understanding the difference that is the key
My Jake's on my c15 are similar to to this my jake only works on the low setting or medium setting I have all three when the truck is cold..but it's throwing the check engine light and now it's saying open jake brake circuit I replaced the setting selector and that didn't help it...any idea whats my issue
I’ve been watching your channel for a while now and find your videos very interesting. I watched your c-13 video on sensor locations but did not see where the iva pressure sensor is located. I got a c-11 with a code 95 on a Peterbilt and from the research I’ve done, the sensor seems to be the common culprit. So I bought the sensor but don’t know where it’s located. My local cat parts dealer couldn’t find the location either on the cat website. The part I bought is a 224-4535. I’m wondering if you could point me in the right direction. Thanks
It's under the stupid valve cover on the C11 and C13. If you rewatch this video you can see it towards the end of the video plugged in to the valve cover base by cylinder 1.
@@AdeptApe okay I will rewatch. Thanks for the reply. I figured it was under the valve cover since I couldn’t find it anywhere else externally. Just wanted to double check before I dove right in. I always make sure to give your videos a thumbs up 👍🏼 Very informative. Thanks again
Not sure on a C11 liter with out a serial number, they are rare. But on C13 and C15 liter you have two types of IVA oil psi sensor's. One with a pigtail and one without. The 15 liter they want the newer one and you have to buy a harness to make the connection. C13 depends on serial number.
@@johngoldsmith6629 yeah the sensor was ordered per serial number and that’s the number they came up with. It did come with the pigtail harness, but for whatever reason, not the small oring. Had to order that separately
@@skywalker7228 That is normal, be careful and don't over tighten the sensor, you will damage the circuit board inside. Best to use a 12 point crow foot so you wrap around the nut. A open end wrench will side load two sides and damage it. Or take a box end wrench and slide it over the wire. They do show it with and with out pig tail sensors. Be careful and SIS has known to be wrong. As of right now a new version is out and it has errors.
Hello. I have 05 kw w900l with acert bxs. And my jakes have only low and high no medium so basically on the switch positions 3 and 1 is high and 2 is low. Cat et shows the same is there a wiring diagram for this or is it supposed to be like that?
A BXS has a Jacobs brake. Which has three separate engine brakes. Low should be the middle hsg. Medium should be front and rear. Naturally high is all three. At the front valve cover connector, pin 10 is for the front, pin 11 is the middle and pin 12 is return for the front and middle. Rear connector pin 1 is supply and pin 2 is return. At the ECM pin 9 is return for all three. Pin 10 is Med/High, pin 11 is Low/High. Also at ECM from cab, pin 5 is your common, Pin 23 is Low/High, Pin 40 is Med/High.
Gotta love it. Just finished watching your aftertreatment class video, probably a dumb question, but by factory password do you mean the same as the SIS login? Just curious because where I work we have E.T. but I'm not sure the capabilities are the same? We are not a dealer but have a lot of Cat equipment. Sadly only one of our "Michigan gravel train" trucks is still Cat powered. Used to have redhead N14's and 2 3406E's when I started. Anyway I appreciate any help to clarify this. Also gotta love a hammer mechanic with red silicone.
Well a SIS login doesn't mean you can acquire factory passwords. You do you a SIS login or CWS technically is what Cat calls it, but then you have to be setup in the Feature Protection System of Cat and as a customer that isn't possible unless you work for a dealer.
@@AdeptApe That's sort of what I figured. Thank you for replying and so quickly at that! Appreciate the time you put in and help you provide. Take care!
I drive a truck with a retarder on the gearbox which works great with 110000 pds gross down 7% ers here in europe. These roads are cleaned round the clock and salted when snow and ice too so i can use it almost all the time.
If all stages aren't working your looking for a command issue, like clutch switch saying its depressed, or wiring issue, faulty switch. If only one or two works or they are delayed most of the time you have a problem under the valve cover. When it's broke you need ET hooked up and see if its in the cab side or engine side.
I'll explain it as simply as I can. Jakes work by holding the exhaust valve open very slightly during the compression stroke. This prevents the compressed air from behaving like an "air spring" because it can escape from the cylinder thru the slightly open exhaust valve. In effect, this forces the engine to behave like a giant air compressor & of course it takes a good deal of energy to compress a large amount of air. That's where the braking force comes into play. To answer your question, the escaping air travels at immense velocity & pressure past the exhaust valve when the Jake is activated (it goes supersonic--that's why straight pipes really talk when the Jakes are on). The velocity/pressure is great enough to spin the turbine faster than it would if the Jake was not activated. A faster spinning turbine wheel spins the compressor wheel faster, so you get boost. It's also compounded by the fact that the engine isn't really wanting or needing the extra boost pressure being developed so it can cause the gauge to quickly spike.
Speaking of Jakes, now that I've experienced them on the new X15 engine with Eaton Ultrashift Plus, they will put you through the windshield and lock up rear wheels if not careful especially empty. Now that I'm back in my DD S60 truck, my Jakes are just noise makers by comparison. I don't feel any retarding effect. Why the difference between two similar engines I don't know but I'm not touching mine since it just recently had an overhead ran by Clarke Diesel. My former 1992 Pete 379 had the 3406E and it too was more noise maker - less retarding.
@@isaacrecord6162 - LoL, when it happened, it scared the living hell out of me. Almost 40-years driving big trucks, I've never experienced Jakes so strong before. This was a brand new rental truck I rented while mine was having major work done due to exploded turbocharger. The seatbelt saved my life that day.
@@AdeptApe I was actually thinking of the injector valve rocker to Jake clearance and then the exhaust rocker adjustment. On the old big cam Cummins you could get a little more brake horsepower without hurting them if you set 2 thousands tight. I did a lot of them but it's been quite a while 🙂
@@AdeptApe I typically work on much larger engines, but occasionally I'll work on some C15,C18,C27/C32 industrials.. More than once I've found injector heights all suspiciously adjusted wrong. Had a customer's " mechanic" tell me he did it to all their Cats cause he could get more smoke.. and in his mind smoke equals power.. (facepalm!) I don't work on OTR stuff, but apparently this is a common practice among on-highway shade tree mechanics.. might be why your injectors were all set "off".
Operating the jakes consistently on high is not a problem for any engine. What do you mean by heating up? Engine coolant temperature during operation or warming the engine first thing in the morning, or something else?
@@cwj9202 I mean at normal (180’) to like 200+ . I really haven’t had this coach out west to take on mountains. We planned on taking off this year, but that plan went to Hell. I did see a modest increase in temp using them.
@@christopherrasmussen8718 - Those temperatures are fine and can rise higher. A slight increase in coolant temperature while operating the jakes is normal and a benefit, as the jakes keep the engine temperature from falling well below normal operating levels.
@@christopherrasmussen8718, Your statement makes absolutely zero sense. Jake brakes do not cause Temps to rise in ANY ENGINE. The jakes are keeping the valves open, so there is zero combustion therefore less heat, so you have a different issue.
Maybe it was a Pac-brake, worst possible choice for an engine brake on a Caterpillar engine. They wanted constant attention, and a slider kit installed every weekend to work correctly.
I’m new to the industry only in my first year at a community college to get my diesel and heavy equipment technology degree. We have a c12 and the Jake’s work flawless from2500- 1100 rpm and cut out and from 1100-600rpm then the truck comes back to idle at 650ish. Any ideas on what could be doing that? We haven’t got to it yet but I was wondering if I could take some good ideas to talk about when we go to fix it
@@johngoldsmith6629 thank you. And I don’t quite know what it turn at max rpm I was just giving a random number. We have the computers at school I guess that’s how we will diagnose it.
Jakes are far more efficient. They have about the same amount of holdback power that the engine has power wise. So if its a 450hp engine can put that much power into holding the truck back. Not even remotely close to how little an exhaust brake is capable of.
3406 A, B and C, 3306 , B and C are low, high. Starting with full electronic engines, 3406 E thru C15 BXS, 3176's, C-10, C-12, C-16 and C-18 used Jacobs Brake. Starting with C13, C15 MXS, NXS and SDP Cat used it's own brake made in with the IVA assembly. 3306 engines you had to be careful, C336 brake used 7/16 push tubes on all serial numbers, including 9TL and 7RJ. 336A was used on a 9TL or 7RJ used 1/2 push tubes on the exhaust. If you mixed them up and used the smaller ones on the exhaust they would fold up like a pretzel.
@@SOU6900 Basically fully electronic engines (engine that has injectors) have three stages. All mechanical and PEEC engines (engine that has nozzles) have two stages. Small engines used a flapper on the exhaust.
Hey, i love your videos, learning all the time, quick question, i have a cat c15 acert mxs, that was in a bad state, way high blowby, oil dripping out the blowby tube. Just did a platinum overhaul on it, everything that comes from cats platinum kit, new head, new injectors, cylinder packs, oil pump water pump ect...and we put 2 new turbos on it cause the top turbo on the old set was not in very good shape...that being said, still got what seems to be some high blowby, and some oil drip out the vent tube, I've heard a worn air compressor can cause this. Anything there? I'm puzzeled, only 3000 miles on platinum rebuild and 2 new turbos and still got the blowby and oil drip out the tube. Sorry for the long comment, love your vids!

That’s why I am very thankful that there are individuals out there willing to share their knowledge. Thank you
@@jeffsimonar7161 to an extent, if you are way out of your league its better to leave it to someone else. 99 times out of 100 i see people cause themselves more money lost because they feel that they can just "figure it out" when they dont understand the basics. i see people take a 200$ problem and turn it into a 3000$ problem very quickly. that being said there is lots of stuff that can be easily taught and done with little training, its understanding the difference that is the key
My Jake's on my c15 are similar to to this my jake only works on the low setting or medium setting I have all three when the truck is cold..but it's throwing the check engine light and now it's saying open jake brake circuit I replaced the setting selector and that didn't help it...any idea whats my issue
I'm always suspicious when I find silicone were its not suppose to be. You think is this a hack & patch job?
I think it's someone who doesn't have confidence in the genuine seals
Maybe they come across it as a common leak and do it now before it causes a mess
wheres your shop? i have weak jakes on my CM870 thanks
Hey Josh, on my KW my Jake brake selector switch goes (high) 3 up, (low) 1 center, (medium) 2 down. So maybe that switch is correct?
what software are you using? ET?
What area was this previous work done
What are y’all’s opinions of the diesel laptops diagnostic software and hardware?
Hi Adept Ape , I have I problem with mi c15 mbn model runs rough after fuel gets hot only on low idle!
Any idea what could be , thank you!
I change all fuel lines and fuel transfer pump, adjust injectors and noting change!
I have weak Jake's also but I have a n14 lol. I have 1 bad injector I'm guessing that might be the culprit.
Haven’t seen you for a while, good look
I have a face for radio and a voice for the deaf. Thank you though.
you gay brah?

I’ve been watching your channel for a while now and find your videos very interesting. I watched your c-13 video on sensor locations but did not see where the iva pressure sensor is located. I got a c-11 with a code 95 on a Peterbilt and from the research I’ve done, the sensor seems to be the common culprit. So I bought the sensor but don’t know where it’s located. My local cat parts dealer couldn’t find the location either on the cat website. The part I bought is a 224-4535. I’m wondering if you could point me in the right direction. Thanks
It's under the stupid valve cover on the C11 and C13. If you rewatch this video you can see it towards the end of the video plugged in to the valve cover base by cylinder 1.
@@AdeptApe okay I will rewatch. Thanks for the reply. I figured it was under the valve cover since I couldn’t find it anywhere else externally. Just wanted to double check before I dove right in. I always make sure to give your videos a thumbs up 👍🏼 Very informative. Thanks again
Not sure on a C11 liter with out a serial number, they are rare. But on C13 and C15 liter you have two types of IVA oil psi sensor's. One with a pigtail and one without. The 15 liter they want the newer one and you have to buy a harness to make the connection.
C13 depends on serial number.
@@johngoldsmith6629 yeah the sensor was ordered per serial number and that’s the number they came up with. It did come with the pigtail harness, but for whatever reason, not the small oring. Had to order that separately
@@skywalker7228 That is normal, be careful and don't over tighten the sensor, you will damage the circuit board inside. Best to use a 12 point crow foot so you wrap around the nut. A open end wrench will side load two sides and damage it. Or take a box end wrench and slide it over the wire. They do show it with and with out pig tail sensors. Be careful and SIS has known to be wrong. As of right now a new version is out and it has errors.
Hello. I have 05 kw w900l with acert bxs. And my jakes have only low and high no medium so basically on the switch positions 3 and 1 is high and 2 is low. Cat et shows the same is there a wiring diagram for this or is it supposed to be like that?
A BXS has a Jacobs brake. Which has three separate engine brakes. Low should be the middle hsg. Medium should be front and rear. Naturally high is all three. At the front valve cover connector, pin 10 is for the front, pin 11 is the middle and pin 12 is return for the front and middle. Rear connector pin 1 is supply and pin 2 is return. At the ECM pin 9 is return for all three. Pin 10 is Med/High, pin 11 is Low/High. Also at ECM from cab, pin 5 is your common, Pin 23 is Low/High, Pin 40 is Med/High.
Very good video.
Good one!!
I'm having the same issues with my C-15. Local dealer that did the work said some Jake's hit harder then others. You want to check these things out?
Gotta love it. Just finished watching your aftertreatment class video, probably a dumb question, but by factory password do you mean the same as the SIS login? Just curious because where I work we have E.T. but I'm not sure the capabilities are the same? We are not a dealer but have a lot of Cat equipment. Sadly only one of our "Michigan gravel train" trucks is still Cat powered. Used to have redhead N14's and 2 3406E's when I started. Anyway I appreciate any help to clarify this. Also gotta love a hammer mechanic with red silicone.
Well a SIS login doesn't mean you can acquire factory passwords. You do you a SIS login or CWS technically is what Cat calls it, but then you have to be setup in the Feature Protection System of Cat and as a customer that isn't possible unless you work for a dealer.
@@AdeptApe That's sort of what I figured. Thank you for replying and so quickly at that! Appreciate the time you put in and help you provide. Take care!
What marker are you using on torqued and adjusted fasteners? I need to start getting in that habit.
I hope someone can help me my truck sometime as full Jake’s, but in the middle of the hill, the Jake’s goes weak
I drive a truck with a retarder on the gearbox which works great with 110000 pds gross down 7% ers here in europe. These roads are cleaned round the clock and salted when snow and ice too so i can use it almost all the time.
I have a c12 jake works sometimes what should I look at ? thanks
If all stages aren't working your looking for a command issue, like clutch switch saying its depressed, or wiring issue, faulty switch. If only one or two works or they are delayed most of the time you have a problem under the valve cover.
When it's broke you need ET hooked up and see if its in the cab side or engine side.
Can you make a video on explaining why you get turbo boost while braking with your jakes?
I'll explain it as simply as I can. Jakes work by holding the exhaust valve open very slightly during the compression stroke. This prevents the compressed air from behaving like an "air spring" because it can escape from the cylinder thru the slightly open exhaust valve. In effect, this forces the engine to behave like a giant air compressor & of course it takes a good deal of energy to compress a large amount of air. That's where the braking force comes into play.
To answer your question, the escaping air travels at immense velocity & pressure past the exhaust valve when the Jake is activated (it goes supersonic--that's why straight pipes really talk when the Jakes are on). The velocity/pressure is great enough to spin the turbine faster than it would if the Jake was not activated. A faster spinning turbine wheel spins the compressor wheel faster, so you get boost. It's also compounded by the fact that the engine isn't really wanting or needing the extra boost pressure being developed so it can cause the gauge to quickly spike.
That was my exact theory but I figured I’d like to hear it from josh but thanks for sharing the knowledge.
Speaking of Jakes, now that I've experienced them on the new X15 engine with Eaton Ultrashift Plus, they will put you through the windshield and lock up rear wheels if not careful especially empty. Now that I'm back in my DD S60 truck, my Jakes are just noise makers by comparison. I don't feel any retarding effect. Why the difference between two similar engines I don't know but I'm not touching mine since it just recently had an overhead ran by Clarke Diesel. My former 1992 Pete 379 had the 3406E and it too was more noise maker - less retarding.
You’re right about the X15. ISX/X15s have the strongest Jake I’ve ever felt
@@isaacrecord6162 - LoL, when it happened, it scared the living hell out of me. Almost 40-years driving big trucks, I've never experienced Jakes so strong before. This was a brand new rental truck I rented while mine was having major work done due to exploded turbocharger. The seatbelt saved my life that day.
Loose valve adjustment?
Valves weren't really off that much, but I reset them. The injectors were way out, several turns, not sure what the heck they set them to?
@@AdeptApe I was actually thinking of the injector valve rocker to Jake clearance and then the exhaust rocker adjustment. On the old big cam Cummins you could get a little more brake horsepower without hurting them if you set 2 thousands tight. I did a lot of them but it's been quite a while 🙂
@@AdeptApe I typically work on much larger engines, but occasionally I'll work on some C15,C18,C27/C32 industrials..
More than once I've found injector heights all suspiciously adjusted wrong. Had a customer's " mechanic" tell me he did it to all their Cats cause he could get more smoke.. and in his mind smoke equals power.. (facepalm!)
I don't work on OTR stuff, but apparently this is a common practice among on-highway shade tree mechanics.. might be why your injectors were all set "off".
Now that was short but to the... point
My jakes started “sticking” in the on position, any ideas? Just had oil change done about 1500 miles ago.
Cold oil, broken spring or bad solenoid, I would check for them first.
Great job man!
I run my Jakes on high when I use them. Cummins ISM motor coach. As long as I’m not heating up, is high all the time bad?
Operating the jakes consistently on high is not a problem for any engine. What do you mean by heating up? Engine coolant temperature during operation or warming the engine first thing in the morning, or something else?
@@cwj9202 I mean at normal (180’) to like 200+ . I really haven’t had this coach out west to take on mountains. We planned on taking off this year, but that plan went to Hell. I did see a modest increase in temp using them.
@@christopherrasmussen8718 - Those temperatures are fine and can rise higher. A slight increase in coolant temperature while operating the jakes is normal and a benefit, as the jakes keep the engine temperature from falling well below normal operating levels.
@@christopherrasmussen8718, Your statement makes absolutely zero sense. Jake brakes do not cause Temps to rise in ANY ENGINE. The jakes are keeping the valves open, so there is zero combustion therefore less heat, so you have a different issue.
@@TheRoadhammer379 glad you know that
I drove a 3406b that had weak jakes. it just made a blubbering whistling noise like a constant-wet-fart. haha
Maybe it was a Pac-brake, worst possible choice for an engine brake on a Caterpillar engine. They wanted constant attention, and a slider kit installed every weekend to work correctly.
I’m new to the industry only in my first year at a community college to get my diesel and heavy equipment technology degree. We have a c12 and the Jake’s work flawless from2500- 1100 rpm and cut out and from 1100-600rpm then the truck comes back to idle at 650ish. Any ideas on what could be doing that? We haven’t got to it yet but I was wondering if I could take some good ideas to talk about when we go to fix it
You can't, engine brake on this electronic engine is programmed to shut off at 1,000 RPM's or lower. Engine should not be able to turn 2500 RPM's.
@@johngoldsmith6629 thank you. And I don’t quite know what it turn at max rpm I was just giving a random number. We have the computers at school I guess that’s how we will diagnose it.
@@Basstaco69 What program do you have?
why do these engines use jakes instead of exhaust brakes?
Jakes are far more efficient. They have about the same amount of holdback power that the engine has power wise. So if its a 450hp engine can put that much power into holding the truck back. Not even remotely close to how little an exhaust brake is capable of.
I always thought Cats just had 2 stage jakes. Thought this was a Cummins because it had a stage set-up.
The 3406B engines had only two housings, but the E models had 3.
3406 A, B and C, 3306 , B and C are low, high. Starting with full electronic engines, 3406 E thru C15 BXS, 3176's, C-10, C-12, C-16 and C-18 used Jacobs Brake. Starting with C13, C15 MXS, NXS and SDP Cat used it's own brake made in with the IVA assembly.
3306 engines you had to be careful, C336 brake used 7/16 push tubes on all serial numbers, including 9TL and 7RJ.
336A was used on a 9TL or 7RJ used 1/2 push tubes on the exhaust. If you mixed them up and used the smaller ones on the exhaust they would fold up like a pretzel.
@@johngoldsmith6629 😆 I'd be lying if I said I understood all that, though I do understand it enough to get your point.
@@SOU6900 Basically fully electronic engines (engine that has injectors) have three stages. All mechanical and PEEC engines (engine that has nozzles) have two stages. Small engines used a flapper on the exhaust.
@@johngoldsmith6629 what about Brakesaver? And what does PEEC actually stand for? I can't seem to find the answer with Google.
That switch is how mine is low is in the middle medium is down
You are the second or third comment saying that on this particular model has them like that.
Hey, i love your videos, learning all the time, quick question, i have a cat c15 acert mxs, that was in a bad state, way high blowby, oil dripping out the blowby tube. Just did a platinum overhaul on it, everything that comes from cats platinum kit, new head, new injectors, cylinder packs, oil pump water pump ect...and we put 2 new turbos on it cause the top turbo on the old set was not in very good shape...that being said, still got what seems to be some high blowby, and some oil drip out the vent tube, I've heard a worn air compressor can cause this. Anything there? I'm puzzeled, only 3000 miles on platinum rebuild and 2 new turbos and still got the blowby and oil drip out the tube. Sorry for the long comment, love your vids!
The air compressor can cause this. Remove the hot hose line and see if the blowby drops.
@@AdeptApe thanks a lot, i will check!
@@AdeptApeis there any risk to the engine if i run it until i can get a new air compressor?
Do you work on IXS Cummins engines?? And if you do, where are you located??
He specialises in Caterpillar, and he says he's somewhere in Idaho.
Good video.
Fluke 87-V for the win!
I have N14 Celect and nobody wants to be bothered with my jake and it pisses me off!
Hey Adapt Ape nice to see a new video from you. Some times it is interessting to see what other mechanics do and the only thing that comes in mind is why :-D
so you never explained why the low and medium settings were backwards?
Just how the switch is wired up, don't matter. ECM is just looking for a ground to know with function you select.
Where are you located?
