- We finally get the best of this L10 Cummins. We also fix some other issue such as oil and exhaust leaks, and new bearings in the bottom end.
Part 1: • Truck Repairs: Cummins...
Setting Valves: • Truck Repairs: L10/M11...
LOVE seeing an old truck being cared for by a skilled mechanic! Keep up the good work Wes!
So skilled he ran it with no valve cover gasket. I feel like CZcams and God shows us the biggest dummies to teach us how not to behave.
As a Cummins tech I love those old L10, M11, ISM11, 855, N14, and K19 engines. Their so nice to work on, real quality engines and extremely reliable as well. Quite a few trucks still have those old men in them where as many have the old 1st & 2nd gen ISX15 and X15 engines which aren’t bad themselves prior to SCR Catalyst and DEF crap. Those older Cummins mechanical, Celect and IS versions of them were great engines and they loved to work hard.
The kind of power where a tech ask questions using the expression “HP is hard hard you hit the wall & Torque is how far you took the wall with you”. Those oldie but goodie engines in some cases made high power and GOBS of torque way down low right where you need it. Today’s engines are emissioned up so bad you luck to make 450HP and 1,800lb-ft going downhill with no load. Their garbage that’s why I grew tired of working on Cummins and working for Cummins inc. I miss the oldies though!!!
Know it’s almost 2 years old but so glad you put bearings in it. Watch videos all the time where they say I just don’t want to mess with it.
You had me laughing at the end, "I'm sure it's just the two of us" pretty funny man.
Cool video
Four!
Just the two of us
We can make it if we try
Just the two of us
@@jasonbode1242 You and I
Thanks for including the test drive. It makes it all worthwhile.
I think the most interesting part of this channel is that every project gets completed that’s just amazing to me. The other channels do not accomplish that and I certainly don’t either.
i watched it all. great video. lots of great detail. back when engines were simple.....simple is reliable.
Thank you. These PT pump Cummins engines really work. This L10 is the best starting engine I've ever seen. If you can get a full turn on the crank shaft, it will start.
HEY, there are three of us here!! Lol
Absolutely agree with you. Simple is the best for DIY and reliability. Now the EPA government nannies are restricting and over complicating the engines to meet their strict emissions standards. If you are in California for one, you have to contend with CARB. They are making people update their rigs with all the emissions trash, or it is illegal to register and drive on the road. Bunch of bureaucratic bullshit that makes it tough for the 'little guys' to make a decent living, and it's just another revenue generator for the state.
@@psavel274 pfffttt try Euro standards with Ammonia, Urea and EGR, AKA AdBlue. You could spend the best part of £10,000 making sure you're under the emissions requirements.
@@stevenbonsall6699
Its not just like that over there in Europe. For example, In California they have extremely strict emissions regulations. C.A.R.B is the California Air Resources Board which ensures you are up to par with all the "proper" emissions equipment in place and functional. They will actually impound a vehicle if it has any aftermarket part installed that doesn't carry the "C.A.R.B" certification, or has a part dedicated to emissions control that isn't functioning. They are also making anyone who runs a rig either install a newer drivetrain with a particulate filter, d.o.c., catalyst, egr, etc, or you are forced to take it off the road. The DMV won't let you re-register the vehicle unless its "updated" with all the current emissions equipment. This can be a hell of a blow to a small outfit that doesn't make a ton of money, or operate on a large scale. You are forced to either swap your vehicle, which we'll say is probably $30,000- $40,000 if you don't do your own work. If you don't swap over, you'll need a whole new truck. Those types of regulations could and have put a lot of guys out there just trying to survive out of business. Bureaucratic pieces of shit that make these ridiculous regulations are all over. Not to mention, almost every vehicle I've seen outfitted with all the emissions compliant equipment actually makes them run much worse, and can drastically reduce the life of it as well. The service department and the parts vendors may be happy over it, seeing how people really don't have a choice but to comply Fuck the emissions bullshit. They act like everything has a huge v8 with a carburetor just dumping raw fuel everywhere with a straight pipe. In reality, the modern stuff is very clean and efficient. These politicians can suck a big one.
Sorry
/end rant.
I'm always impressed with how well Wes can drive. It's not his thing. He fixes them, but drives better than many guys that are paid to drive them.
I thought I had seen every video you had, but happen to stumble across this one. It actually really helped out, I'm doing crank and rod bearings in my 300 Ford next week and watching you do it here gave me confidence. Thanks Wes, good stuff.
Wes could definitely make a great vocational school instructor.
Even open his own apprenticeship program.
If you don't learn something new everytime you watch one of his vids no matter how old you are you're not paying attention pure and simple.
He is a natural trainer. He makes you feel that you are under the truck with him learning how to do it. Some may say if you aren't getting paid why learn?
I laughed so hard at 3am watching this Wes @ 34:45. I love these videos I just go way back in your catalog and queue them all, hit play, relax. So interesting by the way to see you change out the rod and main bearings. I love the way you did that. Very simple explanation and (from what my amateur mechanic mind could tell) executed perfectly. It’s almost like you do this stuff for a living ;).
I always watch until the end
Watched every bit of it! LOVED the road test. Your work is so complete! Really a joy to watch you at work. thanks for sharing!
Awesome as usual. Watched both parts back to back and enjoyed every minute.
Grin was well earned, now bask in the smoke free fruits of your labor. Enjoyed.
Great Job Wes. Love your methodology to the re-build.
Cam
Damn fine job.You and Western farm and Tractor are the best ones I 've seen.
Thanks for the video,alot learned from you guys.
50 minutes is a GREAT LENGTH.!.!.! I enjoyed the length...
Nice job! no job is done until the test drive is over! Thanks for bringing me along
Glad you were able to keep your card! Nice work! Congratulations!
Great video. One of the best. Good to see you getting a good result first go. Eddie from Scotland
Good morning Wes. This is really funny, the more I watch your videos the more I want to tackle it myself. Well you have a good one buddy and enjoy your day.
Incredible job, i am very impressed. You sir have a really awesome truck and your work is amazing.
This is one of THE BEST videos on your channel. From start to finish.. Almost.. To the test drive. Great video man!
Yeah I jammed a lot of work into that video.
You do good work. I have a 94 F250 4x4 pre-powerstroke diesel. Your videos are a big help
Great Job! That cummins sounds so sweet and smooth!! Seems like it has nice power too!!
Yuppers Wes, you are definitely the Wizard of everything diesel engine problem fixin'..
Quite the encyclopedia of diesel knowledge you've accumulated in your noggin' for such a young man as you are.
It's a big part of why it's so enjoyable watching you work.
excellent teacher cool calm and fully understands his work moore vids need em to get through christmas
2nd viewing here. Enjoyed it more this time. Feels like this was a kind of break thru production. Has all the elements: problem, diagnosis, procedure, facetime, success, review. You make us knuckle draggers proud.
Thanks for keeping us up to date. There is a lot to be said for the old mechanical diesels. Keep em coming in the new year! Enjoy it!
Yogi Bear The Cummins stc system is junk , along with the L,10 , should have bought an M11 , No 1fault in the STC system is oil pressure . If it is not in range according to the manual it will not work , period .
I watched it all, I didn't catch it at first but you were working on the old rollback, I'm sure it will give you good service.
I think there was more than 2 of us at the end. Great video and a great result another job well done by a master!
Great video Wes love your prognosis, gotta love a truck that don't smoke
I’m sure your mum was watching until the end :)
Nice job, I hope a little bit of your skill rubs off on me with each video I watch.
Well done truck definitely sounds much better than what you had before. Good luck with it
I had no idea it was possible to change the main & rod bearings without removing the engine. Kind of brilliant!
You did a great job Wes❤, and the job was done properly❤
That croocked steering would drive me nuts... Keep up the good work!
we inserted the"clips" though the holes from the top. start some bolts then squeeze clips and remove from bottom
Yeah that's the way they are supposed to work. I was wrong in the video.
Great video series. Really enjoyed the diagnostic process
The clips are a great idea. I was taught by my dad to use some thin 🧵 and tie the gasket down loosely through a couple bolt holes. After a couple bolts are in, just cut the 🧵 and pull the thread out before bolting it all the way down.
Fantastic video and work! Even tho I understood about 0.005% of the terminology I still enjoyed watching you work.
Awesomeness, definitely more than just us at the end 😊
Wow made it all the way to the end. It is more fun when the truck is ear splitting loud, not for you but for us.
Good video for educating people with same trouble.
Yes Wes, You were AWESOME!...AWESOME, and a great mechanic.
The Florida pool pump motor bearing repair guy approved ! worked on one years ago that the exhaust manifold shrunk. that was fun ....that was good info Wes
I would say that was one mighty fine job you did there cheers brother great video
That engine sounded good. Good job that video brought back memories.
god I love this stuff, such great and well-lit views of the work and great casual commentary infused with a life of experience! I feel like I'm right there with you, but glad I'm not, takes a toll on your body doing this work but the machinery is so marvelous!! Thank you!!!
Best job ever. I watched both videos straight thru and read all the comments to date.I took notes. Some highlights for me were 1. breaking edge with points file to prevent babbit damage. 2. Using brass drift to avoid any scratches on crank 3.Concept of flash rust test to see if metal surface truly clean 4. Your torch method of heating cast iron manifold bolts without quenching to prevent manifold cracking. Plus countless others. Thank you so much. Craig
Great audio in this one! That does sound sweet after the work!
I watched the whole video. As you started driving I got the feeling of deja vu, couldn't quite put my finger on it. Then you made a left turn and I realized I drive that road once a week and was driving that road everyday for over a year when I was going to school to get my degree in Mecatronics. Anyways great job I really enjoyed the video.
Did you go to ICC?
Great content as always! Always amazed at how clean diesels are on the internals.
They make up for it on the externals...
Great tip on the bearings, thank you sir.
Awesome! Having rebuilt two 4 cyl gas engines (way back in the day), I can only imagine the hard work with this 6 cyl diesel. Congrats!
It's all the same, just bigger.
You are a boss on the labyrinth of a shift pattern!
You got the rod bearings in time. Good call.
Loved watching the process.
My July 1999 built Cummins N14 only had 10psi oil pressure at idle at operating temperature; 30psi going down the road.
Night and day difference at idle for sure.
Test drive at the end sounded real healthy. Nice.
Well done on your perseverance with this one. Above all, she sounds well going down the road. I drive a few old London Routemaster buses that were re-powered with Cummins B series engines back in the early 90’s and they run well. Not as musical as the old AEC AV590 but half decent, better than the Italian junk that got put in some of them.
Yeah I have used a bolt with the head ground down to roll out mains back in the day. I'm unable to contortion myself in tight places but I do enjoy working on old trucks when I get the chance.. Well done.
Well done Wes, that was a solid job.
That thing sounds awesome when you're driving it.
great video watched it all and didn't fall asleep...
I’m still with you to the end. Good work.
Enjoyed your wrench'n on this motor bro it looks to be running sweet.
My trick for holding gaskets during assembly is to use fine thread through the bolt hole and tie a knot after capturing the gasket and you can get a bolt through the hole to start it then pull the string to break it and pull the remaining thread out. Who knows if it is the best way but it will work.
Liked your video and watched it all. When it comes to the valve adjustment I've been using the OBC method. Cummins actually had a memo out some time ago on OBC as opposed to IBC method of valve and injector adjustment on Top Stop Injectors. Looks like you done a great job. Take care
Love your skill and patience.
first class job on the cummins very impressed with driving david IRL
Cool! I used to live near a brewery that used BFI to haul away their recycling. They sent a White/ GMC just like yours, only as a rolloff. Every time that hoist moved, I would hear that L-10 growl. I thought it was a Cat engine, now I know for sure it was a Cummins.
Nice job Wes, hopefully she earns her keep.
Congratulations Wes, so glad the L10 is running and idling smoothly. Love that driving footage you got, and the sound quality of that camera you used while in the cab was excellent, plus, the truck sounds fantastic! Can you please do another long driving video of the truck? Make sure to use the same camera you did in this one for the driving portion. And please leave the exhaust how it is. Quite honestly, it sounds absolutely amazing, plus I don't like L10's that don't have a growl to them - much more tamer without one, which I don't like at all - I want them to sound mean! And when you do the long driving video, please make sure to get some exterior shots of the truck driving as well, so I can hear it driving off into the distance. Please let me know ASAP. Congrats once again!
Don't get the big head as I can see you wore a large football helmet but two years later, I am watching for the first time and enjoyed thoroughly. Like you, have worked on that engine, steel oil pan, yahoo won't break in half like the aluminum ones! I love your brand of humor and sense of touch when it comes to feeling your way in. I had those clips for that pan gasket in old tools I bought as a fetish of mine and they were still in the box unused cause when I worked on bigger stuff didn't have them and didn't occur to me what they were for. I can see plenty of uses for them now. I called myself a mechaneck but truthfully couldn't pack your water. As a mechanic, I worked like a rented mule but I just made it harder on me. I'm 72 and memories like this is better than a date with the prom hooker. I have finally learned how to click on the icon for your channel and look for videos I haven't seen. Your better than Netflix and I don't watch tv as it doesn't pay well and I learn from guy like yourself. Some shortcuts I know and others are a lightbulb moment. I remember my first engine, was a 36 chev one ton and what are all these brass things (oh oh!) I couldn't bar it over with a long dynomite bar.... OH....oh, thats what they are for and where did I put them. To get it fixed right I went to the store and bought some brass shim sheets and cut my own out from what I found/LOL. When I was done (I was 12 years old) two days later, I rechecked everything I did and found more stuff (I didn't read but my sister did an she would help me on stuff).... long story short, that engine lived for a long time for what they were in the day as I hauled dirt and firewood on that truck with just a driveline brake. No, your the better mechanic. I remembered everything in those days and now its remember to pull the fly down before you go. Great video
I stuck it out good work on the injectors and the bearings well done
Well done. Both parts. Thanks for the ride.
Excellent methodical work and a great result!
Now it sounds like a Cummins again! Heres a question that nobody has ever answered, what gives Cummins their unmistakeable sound? There must be something in the design because they have a beautiful tone that's unique to Cummins.
I made it to the end. With you all the way.
Another super fix... dedication plus !
Enjoyed worth watching , keep the work up, much appreciated.!
Not a hell of a lot of people know this feeling. And then being able to own it. Do it the way you want to do it... PS happy for you.
That front bearing wear is common on high milage engines for two reasons - front gear train loads and tires harmonic balancer... if I was you I'd change the balancer ...
Foodservice company i worked for.... their fleet had mostly L10 and M11's........You brought back a lot of not so fond memories.......
They are really pretty good engines and well matched to a truck like this.
You're a hell of a mechanic.
Thanks for the ride👍 Always enjoyable.
Another great job done Wes
There’s not much you can’t do . Good job . Old Tool Maker . Fort Worth Texas
It's just nuts and bolts.
I sure would like to find a young dude like you to work in my shop . All I can find is a bunch of green button pushers lol and they want $30 dollars a hour
One of the thin stainless spatulas I use in the lab would work great on removing an upper bearing.
Nice job Wes. Thank you for posting more videos.
I'm trying to keep them coming.
Great series!
Thanks for posting
Wow, that was a lot of work packed into one video, well done. Happy new year! Cheers
Yeah it was.
tradition an français pour moi parce que j'ai parlé pas français
Nice Test drive at the end She don't smoke no more at all nice to see old girl got her issues fixed @Watch Wes Work
You did a good job. watched till the end....
Hey Wes like the work you are doing and have used alot of the same methods / practices like marking the bolts afte torquing.
I never understood why Cummins packaged their gaskets rolled up like that, N14 gaskets came that way too.
I used to find when time permitted I would take the new oil pan gasket, lay the gasket flat between some clean cardboard and place the clean oil pan on top to flatten it out, it usually helped out alot. I also would take a bolt that fit inside the oiling hole on the crankshaft, shave down the thckness of the head and use it to roll out / roll in the upper main beaings.
thanks for the informative video i to have an stc on my 444 and found your info to be the same .they work pretty good old motors if properly looked after .good job
I like your videos, good job explaining the details
Well done Wes.
I have no problem with the not so long conclusion.
If you keep producing the videos, I’ll keep watching. This beats the flimflam, or what ever, out of anything on t.v., except maybe PBS.
