Cooling the Cummins 6BT in this 1953 Kenworth Pacific Bus
HTML-код
- Опубликовано: 8 сен 2024
- In this video I take on a few mechanical problems in this Kenworth bus conversion. The biggest problem was a chronic overheating issue that's been happening ever since it was repowered with a Cummins 6BT diesel. The rear engine pusher configuration has unique airflow, so hopefully I'm getting a handle on how it works.
If you're in interested, here's a link to the far controller I used: www.dccontrol.c...
This channel is criminally underrated. My biggest weakness as a shadetree mechanic is my poor ability to manage wiring/electronics. It was so satisfying to see you clean up the wiring on that dash. This should be an excellent, and reliable adventure rig ! Cheers
Yeah...as soon as an AC unit is inside some motorised vehicle, i nope out on the Electronics...i mean...its so complicated and once someone decides to make all wires Black i want to strangle that exact someone with the wiring...
On a better note, this channel is very nice, it feels homely, the comments are Civil and he doesn't make a charade out of his content. It's so down to earth, that very open with his own faults...
You should (not) see the rat's nest I committed behind the dash of my 62 IH Scout 80 then. 😖 It's almost worse than this bus's under-dash...
Wiring/electronics along with air conditioning is my biggest weakness. I have a very hard time with any wiring/electronics and that's with some electrical engineering classes passed, never did finish and get the degree.
I KEEP SAYN HES DA MAAAN...GREAT MAN TOO....GOD BLESS REAL MEN.....
Underrated is way better than overblown with forced daily videos and full of sponsors
I always get a bit of small joy whenever something old gets fixed or improved with 3D printing. It really just shows the ancient tradition of fixing what's broken does continue into the modern era.
Cleaning up that dashboard and wiring was incredibly satisfying to see! Although it would drive me crazy not having a tachometer.
That close up on your hair when you tested the fans made me chuckle a while.
The original dash is so much cooler than that added on dash. This is such a fun vehicle I'm really enjoying seeing your progress
You should try blowing and low pressure washing dirt and debris out of the radiator itself. Dust, dirt, and other debris builds up in those big radiators and restricts or blocks airflow.
I used to drive and maintain a full size MCI bus for many years.
Good video, and I can feel your pain with the birdnests of added wires and bootlegged systems!
It's amazing the amount of knowledge and ingenuity you possess. Congratulations on a cool running bus. Keep up the great work 👍✌️🇺🇲
I've watched you work on several different vehicles now. Enjoy listening to your knowledge and relaxed ways. As you say, got to be fun.
I have no idea why that top duct was blocked off, but that was intended to be the engine cooling duct. The air comes from there down through the side duct, gets routed to the fan from the back, which blows the air forward through the radiator then the air then exits the side louver. The original fan was huge and blew air over nearly the whole radiator, and was driven by a fan belt from the engine. These busses never had louvers in the rear cover. Gillig borrowed this same design when Pacific stopped making these coaches.
"We've done so much, for so long, with so little...now, we can do anything with nothing at all!" You're damn near walkin' that walk👍
The work you do is amazing and your thought processes are spot on and the way you cleaned up that wiring mess was just Brilliant ,your dry Humor just tickles me to no end Keep on doing what your doing your way it works
That bus is a daunting project for one person. Good job solving the overheating problem. Another good set of fans is the 95 to 00 Ford Contour dual fans. They fit the radiator on a CJ-7 almost perfectly and blow a lot of air. I had a problem with a DC Control fan controller in the past, it was melting down when the fans turned on. They blamed it on my ground being bad and to their credit they fixed it for free but warned me they wouldn't do it for free again. So I cleaned the grounds and even ran a dedicated ground and it burned up again. I replaced it with a Flexalite PWM controller and it's worked perfectly for many years. Hopefully DC Control has solved that problem. I bet one of your belt pulleys is slightly out of round which is making your idler bounce.
Thanks! Sorry to hear about that, I had only heard positive stuff about these controllers before. So far they're working well, but I will definitely update if I run into a problem. At least I have two, so even if one has an issue the other should keep me going at a slower speed.
Congrats Low-Buck Garage, on getting the Kenworth Pacific Bus cooling system working and running great.. great job..
Great work! If I wanted even more airflow, i would make a "floor" for the engine compartment, and close off the rear opening, to force all air out the side
When l 've seen your work last time l said impossible to start it. But now you're amazing really amazing.
This reminds me of the golden years of RUclips.
Awesome work sir. Your skill, ingenuity and dedication to fun is inspiring!
Are you going to block off the back opening to see if that helps with cooling even more?
Ii was thinking the same, will the airflow improve with the rear grille blocked off.
I'm going to check the airflow first, but if air is coming out that vent then I'm definitely going to block it off.
Hooray for a new LBG episode!
Yes sir that cooling system seems to be working pretty good. One thing though when we load a vehicle and put the coals to it the temperature will go up as the engine has more heat to release. Having those fans with the different stages is a good idea. The acid test will be with the bus fully loaded and operating in a hot environment which I am sure the New Mexico area can provide. Even if both fans go into high mode keeping the temperature steady and no hotter than 210 should do fine.
The bus is looking great and glad you've sorted the cooling. One question, are you going to re-close the hole in the back of the engine compartment?
I'm going to check the airflow first. If its losing air out the back, then I'm definitely closing it up.
13:28 One of your best moments in an awful lot of your videos. Excellent! So glad you got rid of that old wiring spaghetti. Man... switches just hanging... so much wire. Great job!
It's soooo satisfying to just cut huge swaths of old spaghetti out like that! The original stuff was causing me nightmares!
You did some great work on that wiring chaos! The new dash looks awesome!
About the cooling, you should try to clean the radiator as well. Degrease it and hose it down, and after that you should try a cleaning spray that are meant for cleaning the heat exchanger in mini split ac systems. This will let the fins in the radiator be able to exchange the heat more easily and you will have a better cooling long before the fans have to kick on.
I don' t know how you manage to video while doing all this practical engineering, anyway, the wait was worth it.
I am glad you jerked out that wiring and restrung new so you know what you got and what you don't. The fans are nice. I would paint the inside with galvanize paint and put a scoop on the top of the air intake. I also would have raised the dash. It looks a little low to me, but that maybe your preference. I would definitely get a functioning speedometer. That disco tech speedometer from Amazon is killing me.
The camera has the issues, not the speedometer. Now for a good tachometer. Have fun
Glad to see you cleaned the differential vent valve. You often need to clean the tube going into the axle tube as it will become clogged. They usually are threaded and will screw out of the axle tube so you don’t have to contaminate the oil when cleaning.
You have 10 times the room to fit into in that radiator space than I do in some of the holes I need to access on my sailboat. I envy you.
See if you can set up a camera to watch air flow direction in the engine compartment and then fire up a smoke machine to see where the air/smoke travels. Then you can try booking off the rear engine cover vent with duct tape and cardboard to see what works best. You and Mortske are the best. Thank You!
Different comment here from the uk , jealous about all the vehicles you have ,but more jealous about all the space you have ,over here they would try to put a housing estate on it ! Love your attitude to restoration.
I love the dry humor, your relentless approach, creativity, and capability
Well done, James! Had a hydraulic fan in an engineroom on a dredge, when
the door to the cab was opened it almost sucked your eyeballs out!
Looking forward to more of your banter and great fixit ideas.
Please post again soon, one can only hold the breathe for so long!
Loving the current video series, cant wait for another Jeep project
Great video, finally the cooling issues are solved
I love your work, more my style and speed. Better than worst, less than best!
Also it pleased me greatly when you ripped out all of that wiring, I love seeing all of the old complicated stuff piled up and knowing there is now a cleaner simpler and more effective ststem in place!
Very interesting to see the troubleshooting process of tracing things backwards to the way they used to be, and should be!
Interested to see where this project goes, and also what other projects you've been up to, keep up the great work!
I very much enjoy your videos! I have a 1987 MCI 102A3 converted to an RV. You give me so much inspiration to just take small problems and just have a fun time repairing them! :) I hear of so many so called pro shops rip people off on these big old Busses :( A person really needs to know there own rig! at least enough to do repairs as you do! :) Thanks again for making it fun and enjoyable! And as you say. . . If it make you mad?!. . . your doing it wrong! Make it Fun!! :)
I really did enjoy your tip about the socket and the drill, keep having fun I do watching you😅
I'd look into the original fan that drove by belt off the engine if possible. Would save a lot of load on the alternator and likely extend it's life. Recently found your channel, great content explained well with just the right amount of dry humor.
Quickly becoming my favorite YT channel.
I'm wondering if the ad-hoc rear vent is necessary any more, with the roof scoop reopened I figure you'd lose quite a bit of air pressure it pulls into the engine compartment straight out the back.
Love how your both a riot and amazingly informative!
I’m glad it worked out for you, it’s going to be a ton of work getting it all sorted out
Your still my no 1 show on utube from Alberta,Canada
that frankin buss is coming along very nicely... by the time your done thats going to one sweet buss!!!
You may want to reinstall that CB radio. It will come in handy on road trips. Great video thank you for sharing.
Great work on the dash and fans. It would be interesting to see wind speeds and pressures in the original duct. Nice tease on the rv. If you had some way to collect the samd in your lot, you would have cheap media to blast the rust.
I must say every time I watch you, and the amazing stuff you do with what a lot of people would call junk, I get inspired to work on my lonely, neglected CJ-5 project. I might actually do it some time too....maybe. Love your stuff brother, keep it goin'!
Well done as allways. Maybe you can arrange some scoop on top of the roof air intake, to improve his efficiency and avoid the rain coming in, at least when static?
Yep, I'm thinking the same thing. You'll see one on there soon!
Congratulations, James, thanks for all the tips with the guages.
You the man James! Thank you for videos. I know it's hard work.
I was going through serious withdrawal but now that I know why you've been away all's good and looking forward to the next episodes.
Wonderful to see the progress you are making on that cool (in every sense of the word) bus.
Nice work on cleaning the wiring.
Excellent video. I am always impressed with how you get custom. Example, I need a key for the latch. This rod should work, just grind a little off.
Now I just need a handle...out comes the cheater pipe...ah perfect!
I love it.
Thanks a million!
Outstanding video!!! Great job on the work. Even better job on the video. WoW! You have a very great talent at story telling and presentation. Your humor is most enjoyable. Thank You so mush for bringing great joy in watching.
I'm glad to see that you more-less did what I mentioned below on your own. I made the comments when you showed that single small fan on the rad. I do have a tendency to jump the gun once in a while before watching the whole show. I do have an idea that you might like and that is to have the temp switches set to shutdown at 100 degrees so if you stop for a bite to eat, The engine will still, already be warmed up to carry on with your trip. Wish you many happy trips !!! Oh yeah hears an idea that you might like, take an old 40-gallon well pump tank that the bladder is worn out and plumb it into the engine cooling system with a heat-exchanger so it has fresh water in it and tuck it under the bed for those cold nights. Nothing nicer than climbing into a nice warm bed on a chilly evening. Just drill 2 1-inch holes in each end and weld the pipes so it is a loop and put a shutoff valve on it in case you don't want to heat the tank up. The fittings that the tank already has is used for showers or just draining the tank so it doesn't freeze in the winter. There are so many uses for hot water in a motorhome you just need a supply tank, you can even put a heating element in it if you want. I did it in my 48-foot boat over 20-years ago and it still works great
Friday evening, with an LBG video and a cool drink. What more could I ask for..?!! Hope all is well James - I look forward to your adventures every fortnight.
That is so "cool" that you licked the overheating problem AND without using 100% of your new system! So nice to have that extra buffer area. Well done, my good man!! 🥶👍🌡🚌🧊😁
I am glad your fixing the old girl up. You don’t see those buses on the regular. Keep up the great work
Brother that was a fantastic video. Your field engineering skills are top notch. And your editing is spot on. Thanks for sharing your talents and adventures!!!
You are truly skilled very nice seeing you save vehicles from the scrape yard time and time again.
Hi , look's like you have a handle on the cooling system for the bus , its coming right along keep having fun .
It's so refreshing to hear good sarcasm!
great progress ,this bus is a gem.
I saw that close up on the luscious locks blowing in the breeze.
Very impressing - last not least because all you do is such goal oriented!
Am loving this series! Will most certainly keep watching you!
Glad you're having fun! And thanks for sharing!
👍👌👏👏👏 Oh WOW, simply fantastic! A lot of serious progress happened. Very well done again (video and work). I like this bus/RV series very much. To be completely honest: I didn't know that you are able to do such complex jobs because you kind of fooled me with your usual lax way of doing things while working on old vehicles (at least in all the videos I've seen so far). But now I definitely know better! Therefore > Kudos! A ton of things work fine on/in this old bus now. You even removed a spaghetti nest of wiring including the upper dashboard. The sight out of the front is so much better now. Congratulations! 2) Do you think that it is necessary respectively better to close the mesh in the engine compartment hatch/door now? This may even improve the airflow even more!?
Of course I'm eagerly looking forward to watch your next video.
Thanks a lot for making teaching explaining recording editing uploading and sharing.
Best regards, luck and especially health to all of you.
That was fun, thanks for taking us along for the ride.
Splendid Engineering. Looking forward to many bus projects and maybe a few trips!
The bouncing belt tensioner is caused by the unforgiving serpentine belt in combination with a Diesel engine. I had the same issue with a 6 Cylinder Benz, a freewheel pulley on the alternator was the fix.
I wish I could do this! You're living the dream. Awesome videos
Mechanic's inspection report: "It's a roomy son of a bitch."
Yes it is! As a single guy and minimalist, I could live like a king in that thing.
Thanks for cleaning up that chaotic wiring. Even as a viewer, it was driving me nuts.
I’m having fun with my projects too thanks to you, Sir. Always a pleasure to watch👍🙏👋
Hands down one of my FAVORITE channels on RUclips!
What an awesome improvement 👍
Good stuff,keep plugging and I’ll keep watching
Great job. Well done. New sub, just finished watching the air installation so now im gonna watch the upgrades on the inside.
I really enjoy your thought processes. You and could build a Mars vehicle for less than $100. Keep building
Outstanding job !!! Appears that you have solved the problem and made the 'cooling effect' to possibly work in even extremely hot weather to boot.
awsome work on that cooling system i always learn some neet little work arounds keep on truckin
Always a joy to watch your understated engineering keep up the fantastic creations .
Nice Job on this Project you're doing here. I shore like this 0l' Bus of your Dad's had at one time. Look's like you got the gauges all under control now👍🏼👌🏼
This channel is a hidden gem.
Watching you remove all the excess wiring was quite cathartic. :)
It would help even more if you panel over the hole in the rear engine access panel/ trunk lid, which should save some fan energy. I guess you were right about the air flow direction with the discovery of that roof intake.
Excellent video James :) also like solving Kenworth bus and think on top air would make like Hood Scoupe with inlet foward to bus plus metal window screen on gap glue on or screw on Hood Scoupe plus it bolt on too ! Hope like try that no with that idea!
that hydraulic fan is badass! thanks for the tip of those fan controllers too, I am starting a project of putting a 1.9 VW TDI diesel engine inside a F350 crew cab flatbed with a 6 speed and I know Ima need some good cooling so I'm going to pick up one of those controllers
That socket trick is pretty good
*Phenomenal job with the re-wiring James!* 😁👍 Glad to see the fans are working like you hoped they would. That hydraulic fan is a great backup plan as well. Enjoyed this video very much. It's incredibly inspiring to see how you adapt and overcome with any issues you face. Happy wrenching 🔧🔩
Great work, often times it trial and error. Seems you nailed this last go around. Those springs on steering assist the wheel returning to center after a sharp turn. Witnessed it working as you pulled out to test drive. thanks for sharing!
The cooling fan in a Lincoln Mark 8 is a 2 speed and believe me it is the best fan money can buy.
I love watching this. The bus is really cool.
Your always so entertaining,knowledgeable and informative. Thanks love your content.
Good to see your doing well and appreciate the bus update . 👍🙏✝️
Enjoyable video to watch...what a cool bus!
you make watching , enjoyable. and i love your bus.. id buy a box of your left-overs too. (gauges) keep teaching us.
ok, the socket trick is awesome, Never have see that before.
Glad to see two alternators; I must have missed that video or you didn't record it.
I hope one of them runs the charging system and the other runs the cooling fans, with their own battery.
Could use the charging system battery, as a house battery too.
Deep cycle battery would work well and last longer.
Could also add a solar panel to the roof.
That big hydraulic fan would work as well as a mechanical fan, if shrouded properly.
Might be able to add power steering too, since the hydraulics is already there.
It would be easy to add electric power steering to it now. Might want to research that.
Kits are very common and parts available in the junkyard or aftermarket components online to build own.
I added aftermarket electric power steering to my Polaris 900XP side by side, with a kit from Super Atv.
After installing that kit, I could add electric power steering to any vehicle.
It's very easy; could chain drive it to steering shaft, if needed.
After I installed it, could not imagine not having it and wanted to add it to my 4x4 atv.
