The world would be so much better off with people like Warren in it, people who take pride in their work and do the right thing for their customers. Good job Warren.
I used to be a field service mechanic..this is exactly why i finally got out of it..too much stress trying to placate too many customers with too little appreciation of the amount of work involved in diagnose/repair of literally every year make and model of vehicle or equipment. You are a rare individual sir, and I compliment your integrity.
Such a dedication to fixing correct learning and not giving up. Qualities that are very seldom found in a heavy duty mechanics not to mention the added frustration of videoing. Everyone could learn from you Warren
Your ability to keep your calm, on youtube or in general, is damn amazing. I sure wish I lived closer to you, to help out.. I feel your knee pain everytime you gotta crawl out from under that truck to get a tool, etc. Kudo's to you for your determination.
Warren, why does everything have to be so fucking complicated anymore? Sensor this, sensor that, regen,dpm. You are correct about common sense. You said it about fixing it. Looks good on paper.
Rest assured Mr Hewes knows who you are, Warren. A bunch of us recommended your channel when Joe was trying to fix a John Deere power shift tractor. Those guys are a riot. Make sure you watch the video where they drag the Cat excavator home.
Warren, One thing to do, is unplug all the injectors and check the resistance of each coil. One could be shorted and pull the drivers down inside the ECM. I had an engine do this one time and caused erratic injection timing, and ultimately a no start. Had no codes as well. Was a Cummins engine though. Crank no start with no codes and no smoke. Once I found the shorted injector coil, I left that one unplugged, and the engine fired up. When you have cam or crank unplugged, it wont fire injectors, so you'll get normal cadence cranking. I feel your frustration, I really do. Shop owner myself.
You have been dedicated to always making thing's right, and figuring out the problem, hope tomorrow is the fix. You are doing well with all the frustration, i know a couple guy's who would have been so mad, they'd have thrown shit everywhere, and would have about had a meltdown over something like this. G-d bless, hope you got it.
You hit the nail on the head @3:40. I am an engineer for a large equipment OEM and im in my 40s. I am one of the few that works on equipment in my spare time and grew up doing it. Most do not. And the younger group coming in rarely have any hands on experience with equipment or working on things. It doesn't look like it will get any better. And us older experienced engineers can''t catch all the serviceability issues and even if we do, we get overuled by managers who say thats a nice to have. Bigger flywheel housing costs more money so some manager with no hands on equipment experience probably nixed that because of extra cost!!!
All credit to you Warren for filming the problems mechanics have to deal with. When things don't work you waste so much time second guessing what you did to try and figure out what happened. Plus being self employed you end up working for free. You do an awesome job. Keep up the good work mate.
Words cannot make a COMPLIMENT HIGH ENOUGH for your level of knowledge and Professional and Personal dedication to DOING THINGS Right and Figuring out issues and z problems !!!! Great Work Again !
Mr Hewes is a Farmers son. They act a bit daft , But he really knows is stuff on fixing military vehicles. I've not seen your links for two weeks. Just had some pop up. Unusual.
We’ve had one in the shop before where we had the same situation checked timing again like you did, turned out both new unit pumps were bad and once replaced it fired up.
Measure from where the mating side of the timing cover (where it meets the back of the block) to the center of the cam sensor head mounted in the timing cover. Then you will know where you need to locate the tone ring, as far as spacing.
My hats off to you I’ve been wrenching for 11 years and soon I’m changing careers and becoming a truck driver. Have a lot of respect for those who still are repairing diesels. Im not longer interested in throwing wrenches at these trucks any more the money is not there at least for me.
Mr Hewes is a good RUclips channel to watch. You made me laugh when you were talking about engineers make thing you can’t work on. And the manufacturers are to cheap to build it to last.
I feel like the engineering behind these machines absolutely is designed with the mind of how to put them together. I think they make it purposefully difficult.
How funny...just wated a mr hughs vid, will check out the guy in aussie now... Warren thanks for bringing us along on this one. Appreciate all you do. Thank you
Hi Warren, Bruce is awesome, and so are the guys who work on the tanks here in the UK, if you saw the Leyland Martian video I can confirm that by UK standards that truck is a monster.
When I worked on a Polaris 400 Ranger. Rebuild the piston and upper head etc. All together and it wouldn't start! Redid the time even took it half way down to line up the timing chain. Started up finally then died! I realized after the 10th time tearing it down that the woodruff key had sheared off so the flywheel lost time! I was so upset that I didn't think about that being the problem!
I feel for you on this one Warren. Are we sure that camshaft update didn't require any change to the gear or any other related parts. The fact this new camshaft is different from the old one, is a bit suspicious to me. You showing a lot of grit, determination and wisdom getting this sorted. This is a fascinating series of videos. It also speaks volumes about your honesty and willingness to help others with your experiences. I can't wait for the conclusion to this one. Thank you Warren.
I would be ashamed if my son was the engineer of this piece of crap. All the money spent on schooling and this his best. Good luck keep us informed on your progress. Thanks once again for sharing Warren. Hang in there!
Hang in there you will get it figured out. Hopefully the cam is the right one. to me you had the cam gear installed right. It needs to be supported by the boss on the end of the cam and not just the bolts and pin. Good luck!👍
When you crank the engine do you get white smoke out the exhaust? Yes would be a timing problem, no would be a fuel problem which is what I suspect. When truck initially come in had a code for small fuel leak. Nothing external so had to be internal. I believe you said the high pressure fuel rail pressure was considerably high now. High pressure there would cause your injection pump rollers and can premature wear so this may have been going on for a while. Injector line must be seated correctly and torqued correctly or will leak across to the return and won’t fire. If this was your problem you wouldn’t show high pressure. Try to determine which cylinder is firing with a thermo gun and then track injector line back to rail and start looking for a blockage in the fuel rail. Could even be a pice from old injection pumps. Also for shit and giggles try starting with one of the injection pumps unplugged and then the other. I’ve heard of them running on one pump but not with the other or both plugged in. Injector line go bad on these is common and can leak internally. Should have about one thread exposed when these are seated correctly. If that was the case you would have low pressure and your sensor would need to be bad since you’re reading high pressure. Premature pump lifter wear still sounds like pressure and that would need to be a blockage or bad high pressure regulating valve. Good luck.
Another thought, too high of pressure with new injection pumps maybe from a stuck pressure regulating valve, maybe above working limit of injectors and can’t open when pulsed. Unplug one pump and try.
you wonder why kids are like "fck this man, I'm done". I'm stressed out just watching a video let alone laying in oil on a cold day as my country crumbles around me. God Bless you Warren, I dont know how you do it
There was a cam campaign and with the campaign there was instructions on the spacer to leave it out. Research the campaign and see if you have that situation going one. If so, that spacer is left out.
At 27:13 you can see the triangular witness mark of the tone wheel bolting directly to the gear.....so the spacer plate must be behind the gear. I wonder if the new cam eliminates the spacer, and the gear bolts directly to the cam....with the spacer ending up in the used parts bin??? EDIT: I guess i should have watched further in the vid before commenting.....you'll figure this one out Warren!
Sorry your having to deal with this, sure makes for interesting videos. been trying to do research for you as well but just not getting anything you don’t already know
It's a stretch ,but I had a hemi in a ram .set the timing up from the book . Problem was a speed sensor that communicated with the ecm something magnetized touched the sensor and then the ecm wouldn't recognize it so the truck wouldn't start . Just a thought . Good luck hope u sort it out . Safe travels
Warren, if the turbo ends up not being the root issue, I would really encourage you to remove the high pressure fuel lines and the fuel rail and make sure all those passages and clean and free of debris. I’ve seen where debris can stop up the high pressure fuel system and cause the high rail pressure like you were reading and not let the engine start. Hope the turbo is the actual issue!
Worked on a msd tbi efi aftermarket , on hot summer days it would do a no start because the fuel pressure would exceed 60psi and shut the injectors down , he had the pump regulate the pressure with no return, put a return with a regulator in line so it would dump pressure after 50psi it was the fix for that
If that sucker fires off on ether then it’s almost electrical or fuel related. Sure got your hands full especially when you got other jobs to get on. I feel for ya
The main thing about the cam gear is that the idler gear must mesh fully in line with the cam and crankshaft gears. If you'd put the spacer under the cam gear if wouldn't have lined up. You used common sense in putting the spacer on the outside so the fixing bolts still went through the same thickness of materials before screwing into the crankshaft. They might have bottomed out otherwise? What a PIA it's been proving that you did a perfect job the first time. As you said if thevtiming had been wrong the engine wouldn't have turned over when you adjusted the valve ckearance.
I have seen gas vehicle engines with a plugged muffler and exhaust systems that would actually spin over and when I let off the starter the engine was spin backwards because of being so restricted
Had one kicked my ass ! Went to dealer end up spend over 15 k before they put a complete fuel module on! Started right up! Respectful hope this helps! Wish I was there to help ya!
Hey Warren, maybe there is an updated tone wheel/drive gear to go with the updated cam ? Measure the shoulder length from the captive plate groove to the front face on both cams, see if they are different lengths, that may give you your answer ?
It looks like the washer spaces the cam and tone ring out. It looks like it will effect tone ring depth. I would put the washer. Behind the cam gear and check the tone ring depth assembled, then make a judgment
holding your breath as you turn the key on a reworked engine..there is a good reason that first time you spin the starter is nerve wracking...because of these kind of engines, the ones with 6 things bad in them
The problem with design and engineering is, it's not about the customer or the service tech anymore, it's totally about the shareholders and the bonuses made by corporate execs! I am posting this before end of video, so don't know if this thought was addressed further in or if problem resolved, but is there any possibility you got the wrong cam from them?
Re extracting a flywheel with such little clearance around it, I used to use two or three pieces of threaded bar in place of the original fixing bolts to slide the flywheel clear of the housing. i used two pieces of welding rod with the end 1/2" bent over at a right angle slid into the gap between the outer diameter of the flywheel and the casting until the rod could be hooked to the crank side of the flywheel to pull the flywheel on to the threaded bar.... This occurred on some tractors I worked on, not this engine. What was the measurement of the location groove on the original camshaft to the gear face meshing with the camshaft gear ? Leaving the original spacer OUT, does the gear face match up. Just a thought. (With all the different jobs on the go in your workshop, I admire you keeping on top of the workload.
You going to put a big sign on the front door I no longer work on trucks with Paccar MX engines😂 When you were cranking the truck over the first time it was woofing in the intake the VGT was closed so you essentially had an exhaust brake. This new shit is too over complicated fvcking sensors here there, if it breaks you have a wild goose chase finding the problem. Of course they don't give you any literature with the updated/revised parts the service manuals are not updated so you are left to your own to try figure shit out.
The silver lining is you get to remove that spacer that’s not needed anymore. Joking aside I think you’re getting pretty damn close Warren. Your perseverance will pay off
I'm probably wrong but I believe that washer looking thing is only just a spacer so my thinking is it helps if it has too much protrusion like that other cam. It may not be necessary but again I'm probably wrong and have absolutely no experience. Good luck
Warren, I am not a truck mechanic, but I’ve worked on farm equipment. Is there some way you can check if the tone wheel lines up with the speed sensor? The end of the new cam could be thicker than the old one and the spacer throws the edge of the tone wheel off the sensor. Maybe the spacer should be left off.
I’ll put money on it it’s a fuel issue. DAF makes these engines so only a dealer can work on them. You need to measure injector return flow and see if the rail is returning too much.
With the spacer installed on back of cam, the dowel barely protrudes, could the tone wheel have been indexed wrong?, I like the restricted exhaust theory also.
To tell you the truth , i would have gave up on paccar the first time i work on one. Just like i did the 6.0 and newer ford diesel and 5.4 3 valve. We just refuse to work on them .Not worth growing extra grey hair.
Hey Warren, I don’t know anything about that POS Paccar… My brother is a good mechanic… one time they where rebuilding a cat, think like a C15, they got another engine to swap some parts..they got it together and it Would run but was doing some crazy shit like smoking and throttle was not Working and like it was having a seizures … they caught hell figuring it out… long story short, they had the wrong cam it the engine… they went back to the core engine at the junk yard to get it, dam thing fit but was for a different set up
Why does flywheel timing make any difference anyway? Speed sensor will read speed regardless, right? Wouldn’t it just be for balance more than anything else?
bravo ,I went thirteen round with a ford gaser six (F I) no fire misfire ,and after 3wks it was ground to block on injector circ ? ,ecm switches grnd . ,so true engineers are a bucnh of dopes try access to airpump on vovlvo d 13 or mack m8 or egr all in back at fire wall no way to get to it lift cab? oh its a Pacar there ya go .rated at 375 puts out 250
Are there two different types of flywheels? If the farmer was able just do and community different engine I do know that you would have to change the engine mount. For a completely different engine out side of the Paccar to a different engine. Sincerely! R.S.V.
Shot in the dark, but could injectors or injector harness cause an issue? Maybe when it initially fired, it turned over and grabbed a wire or something and that's why it quit and won't restart?
I haven't seen a current video so you probably got it figured out by now but,2 things,1- updated shit scares me,anytime one thing is updated usually it corresponds with something else,in other words,the updated cam probably requires other updated parts that those parts jockies don't know about.like the tone wheel.how do you know the bolt holes are in the correct spot to accept the cam gear and be timed properly? You got to remember those stupid paccar motors are made by cummins and anytime I've run into an "update" there's almost always been more to it than just one part.i would put the cam gear and tone wheel on and make sure it lines up with the sensor,you can be off an 1/8 " and it wont run,and if the high spots on the tone wheel are in the wrong spot it will be out of time even tho your marks are correct.anyway,enough rambling,i hope you figure it out because i thought i was the only one that got those brain teasers
Warren it looks like the tone wheel was not under the sensor all the way for it in the bell housing with that shim washer on the outside of the cam gear instead of in between the cam and the gear. With the Tone wheel not all the way under the sensor there may have been not enough of a signal to trigger the firing circuit in the ECM for the injectors. Does the service bulletin have a new cam gear that has to be installed for this updated cam shaft or maybe a new tone wheel? We had a similar problem when a tech install the timing gear back to front on a gear box and we could not get a reading from the speed sensor. That gear installed that way was just on the edge of the sensor reading it but it was not sending a strong enough signal to the controller to get the ignition to trigger.
Hey, if the spacer is one the outside of the gear like you had it does the dowel to index the tone ring sprocket still engage? Wondering if the tone ring sprocket was not in the correct spot because if the dowel doesnt engage you have 3 different ways to put it on based on the bolt pattern.
The world would be so much better off with people like Warren in it, people who take pride in their work and do the right thing for their customers. Good job Warren.
Warren is the BEST
@@jaygraham5407 fact
Agreed! However I’m like Warren, and where I’m from there is not much appreciation! America is in a sad state of affairs!
@sydsyd I absolutely agree. Respect and Responsibility are no longer in today's behavior.
I'm an Australian, and I do worry about you guys; then I watch WTTR and am reassured. If only you had a “cando” practical President like Warren.
I used to be a field service mechanic..this is exactly why i finally got out of it..too much stress trying to placate too many customers with too little appreciation of the amount of work involved in diagnose/repair of literally every year make and model of vehicle or equipment. You are a rare individual sir, and I compliment your integrity.

I’m on the edge of my seat waiting for the next update.. thanks Warren for all the education….
Rest assured Mr Hewes knows who you are, Warren. A bunch of us recommended your channel when Joe was trying to fix a John Deere power shift tractor.
Those guys are a riot. Make sure you watch the video where they drag the Cat excavator home.
Warren,
One thing to do, is unplug all the injectors and check the resistance of each coil. One could be shorted and pull the drivers down inside the ECM. I had an engine do this one time and caused erratic injection timing, and ultimately a no start. Had no codes as well. Was a Cummins engine though. Crank no start with no codes and no smoke.
Once I found the shorted injector coil, I left that one unplugged, and the engine fired up.
When you have cam or crank unplugged, it wont fire injectors, so you'll get normal cadence cranking.
I feel your frustration, I really do. Shop owner myself.
Yes try disconnecting three injectors at a time , see what happens
Hi Warren. From Victoria Australia 🇦🇺 its 11.37pm trying to go to bed but had to watch this first 👍👍👍👍
You have been dedicated to always making thing's right, and figuring out the problem, hope tomorrow is the fix. You are doing well with all the frustration, i know a couple guy's who would have been so mad, they'd have thrown shit everywhere, and would have about had a meltdown over something like this. G-d bless, hope you got it.
You hit the nail on the head @3:40. I am an engineer for a large equipment OEM and im in my 40s. I am one of the few that works on equipment in my spare time and grew up doing it. Most do not.

It is always so simple once you find it.
Finding it is rarely simple.
Mr Hewes is a Farmers son. They act a bit daft , But he really knows is stuff on fixing military vehicles. I've not seen your links for two weeks. Just had some pop up. Unusual.
We’ve had one in the shop before where we had the same situation checked timing again like you did, turned out both new unit pumps were bad and once replaced it fired up.
I would say the pump units are ok as there is excessive rail pressure ,the injectors are blocked and not firing due to dirt /debris
Measure from where the mating side of the timing cover (where it meets the back of the block) to the center of the cam sensor head mounted in the timing cover. Then you will know where you need to locate the tone ring, as far as spacing.
I was thinking the same just to know for sure that the tone wheel is running close enough to the sensor.
My hats off to you I’ve been wrenching for 11 years and soon I’m changing careers and becoming a truck driver. Have a lot of respect for those who still are repairing diesels. Im not longer interested in throwing wrenches at these trucks any more the money is not there at least for me.

Good luck to you on fixing this. I have been there myself so know about how you feel.

Warren thanks for bringing us along on this one. Appreciate all you do. Thank you
Hi Warren, Bruce is awesome, and so are the guys who work on the tanks here in the UK, if you saw the Leyland Martian video I can confirm that by UK standards that truck is a monster.
When I worked on a Polaris 400 Ranger. Rebuild the piston and upper head etc. All together and it wouldn't start! Redid the time even took it half way down to line up the timing chain.

I was so upset that I didn't think about that being the problem!
Of course it was not a semi truck engine like this but that was a confusing and upsetting endeavor
you dont, give up warren you keep going till you find it no such word as can,t do it 👍👍👍👍👍
Upvoted for the high value entertainment. You'll get it Warren. We know you will!

Great troubleshooting Warren, can definitely relate to finding out the problem was between my ears lol.
I was thinking outside the box and wondered if the Cam Shaft has been machined wrong ??? I feel your pain Warren.
I would be ashamed if my son was the engineer of this piece of crap. All the money spent on schooling and this his best. Good luck keep us informed on your progress. Thanks once again for sharing Warren. Hang in there!
My guess is that spacer is strictly for tone wheel depth alignment (on the old cam). The cam cut lengths are different.
Can’t wait for the next video! Good job explaining everything I think your on the right path man
Man you impressed me every video warren you will get it . I normally want comment on video but headed man your awesome!!!!!!!!!!!!
Hang in there you will get it figured out. Hopefully the cam is the right one. to me you had the cam gear installed right. It needs to be supported by the boss on the end of the cam and not just the bolts and pin. Good luck!👍

The struggle is real..the struggle is real...frustrating for sure...
Some day are diamonds some are coal makes you wonder if you're working in a coal or a diamond mine. Keep up the hard work you got a good work ethic
If gears are aligned without washer under it, it’s good.

Re extracting a flywheel with such little clearance around it, I used to use two or three pieces of threaded bar in place of the original fixing bolts to slide the flywheel clear of the housing. i used two pieces of welding rod with the end 1/2" bent over at a right angle slid into the gap between the outer diameter of the flywheel and the casting until the rod could be hooked to the crank side of the flywheel to pull the flywheel on to the threaded bar....

Warren, I am not a truck mechanic, but I’ve worked on farm equipment. Is there some way you can check if the tone wheel lines up with the speed sensor? The end of the new cam could be thicker than the old one and the spacer throws the edge of the tone wheel off the sensor. Maybe the spacer should be left off.
I’ll put money on it it’s a fuel issue. DAF makes these engines so only a dealer can work on them. You need to measure injector return flow and see if the rail is returning too much.
very Interesting Warren A If you dont no I dont no.
Just remember at the end of the tunnel is always a bright light at least that’s what we hope for
Yeah that hurts. Right in the pocket.
If Joe Biden was a truck engine, this would be him!😂
isnt there two dole holes in the crank though warren? have a look it looks like it from here, love ya vids 👍
With the spacer installed on back of cam, the dowel barely protrudes, could the tone wheel have been indexed wrong?, I like the restricted exhaust theory also.
Tone wheel is attached to the gear directly and doesn't need a dowel because it gas triangular bolt patern and 6 magnets equally spaced.
I wanna see you get it running
Did they update the cam to get rid of that spacer?
To tell you the truth , i would have gave up on paccar the first time i work on one. Just like i did the 6.0 and newer ford diesel and 5.4 3 valve. We just refuse to work on them .Not worth growing extra grey hair.
Hey Warren, I don’t know anything about that POS Paccar… My brother is a good mechanic… one time they where rebuilding a cat, think like a C15, they got another engine to swap some parts..they got it together and it
Would run but was doing some crazy shit like smoking and throttle was not
Working and like it was having a seizures … they caught hell figuring it out… long story short, they had the wrong cam it the engine… they went back to the core engine at the junk yard to get it, dam thing fit but was for a different set up
hang in there buddy you will figure it out
If the VGT is closed would it still run on ether? I think you're on to something.
Sometimes what should be a routine job turns into a friggin nightmare. Poor quality OEM parts cost me $3K and I’m the installer and have to eat it.
Why does flywheel timing make any difference anyway? Speed sensor will read speed regardless, right? Wouldn’t it just be for balance more than anything else?
Had a Cummins turbo wasn’t letting anything through loose the turbo and started
bravo ,I went thirteen round with a ford gaser six (F I) no fire misfire ,and after 3wks it was ground to block on injector circ ? ,ecm switches grnd . ,so true engineers are a bucnh of dopes try access to airpump on vovlvo d 13 or mack m8 or egr all in back at fire wall no way to get to it lift cab? oh its a Pacar there ya go .rated at 375 puts out 250
I watch the professional struggler he told us about your channel
The spacer was deleted....and your injectors are blocked....on the exhaust side when the VTG fails in a certain position they wont start
Are there two different types of flywheels?
If the farmer was able just do and community different engine I do know that you would have to change the engine mount. For a completely different engine out side of the Paccar to a different engine.
Sincerely!

Shot in the dark, but could injectors or injector harness cause an issue? Maybe when it initially fired, it turned over and grabbed a wire or something and that's why it quit and won't restart?
Is the cam longer?
Did they send you the wrong cam?
Hi Warren could they have sent you the wrong cam?
I haven't seen a current video so you probably got it figured out by now but,2 things,1- updated shit scares me,anytime one thing is updated usually it corresponds with something else,in other words,the updated cam probably requires other updated parts that those parts jockies don't know about.like the tone wheel.how do you know the bolt holes are in the correct spot to accept the cam gear and be timed properly? You got to remember those stupid paccar motors are made by cummins and anytime I've run into an "update" there's almost always been more to it than just one part.i would put the cam gear and tone wheel on and make sure it lines up with the sensor,you can be off an 1/8 " and it wont run,and if the high spots on the tone wheel are in the wrong spot it will be out of time even tho your marks are correct.anyway,enough rambling,i hope you figure it out because i thought i was the only one that got those brain teasers
Warren it looks like the tone wheel was not under the sensor all the way for it in the bell housing with that shim washer on the outside of the cam gear instead of in between the cam and the gear. With the Tone wheel not all the way under the sensor there may have been not enough of a signal to trigger the firing circuit in the ECM for the injectors. Does the service bulletin have a new cam gear that has to be installed for this updated cam shaft or maybe a new tone wheel? We had a similar problem when a tech install the timing gear back to front on a gear box and we could not get a reading from the speed sensor. That gear installed that way was just on the edge of the sensor reading it but it was not sending a strong enough signal to the controller to get the ignition to trigger.
How many miles are on that engine if there are over 3,000.00 miles on it i would just replace the engine
Hey, if the spacer is one the outside of the gear like you had it does the dowel to index the tone ring sprocket still engage? Wondering if the tone ring sprocket was not in the correct spot because if the dowel doesnt engage you have 3 different ways to put it on based on the bolt pattern.
this truck end up in your hands because you are the only person capable of fixing it
i think what he meant there is two dowel holes in the crank flange
Could the tone wheels on the cam or crank be pressed on out of sync? Never have worked on a Packnar.
