Increasing this Truck's Top Speed From 67 MPH to 93 MPH [Cummins Swap Part 26] 

My hat’s off to you Waldo, for setting up new diff gears while lying on the ground. Talk about a test of patience! I think your mileage should be pretty good with the Cummins running at 2100 at highway speed. Keep up the great videos. 👍

This has quickly become one of my favorite builds on RU-vid. 👍

Took me forever to find this guy…really enjoying this project so far

Awesome, Waldo! You’re the very embodiment of the need for right-to-repair. With extra credit for doing it while lying under the vehicle on a first/straw/soil floor. Keep on truckin’!

I would recommend buying a set of bearing that is from the same manufacturers as your kit. Measure the bearings to make sure they are the same. Take one set of bearings and enlarge the bore so they slide on and off the gears. You can use these enlarged bore bearings to find how many shims are needed and easily pull the bearings on and off as need. When you get the correct amount of shims, lash and mating pattern then install the other bearing set for final assembly

I love how knowledgeable and caring this guy is with everything he does. Like the flatbed and the gooseneck.

You're an inspiration dude. Thank you for being so thorough with your explanations. A lot of guys on RU-vid use videos like these to vent a little or tell you some long winded story about life... Really appreciate it!

The thing about this truck is that typically it’s harder than it looks to get that simplicity of minimal design while doing quite a bit of work, but you’ve nailed it. Great looking ride that people must take seriously.

The hammering bit around 7 minutes had me laughing... out loud.. at work.

So....this got just randomly recommended to me on my front page. Two things, this video is fucking awesome man, your truck is sweet and your video was extremely interesting to watch, I think I'll go through and watch the entire build now. Secondly, I just about choked on my drink when I saw you merging on to the highway from my hometown, for one reason or another I didn't even recognize the area in your first clip in the beginning of the video so it didn't dawn on me until the end of the video. I was born and raised in that town and lived there for over 20 years. Pretty insane to just randomly stumble upon your channel like this out of the blue, not only a rad truck and build but also someone living in my former stomping grounds with such a rad truck. Keep up the great content man

One of the best channels on RU-vid, I like your editing style and just the way you do videos in general. Nothing over the top, don't take yourself too serious, not flashy. Wish you the best!

Dude your doing a fantastic job at this whole thing, I’m a professional technician and I tip my hat to your quality of work sir, amazing video on diff work and that’s hard enough by itself

I have the Dodge NV4500 in my 87 Squarebody along with a 1997 Cummins P-pump 12 valve with 3K governor springs and compound turbos, I had 4.10 rear ratio and I only got to 73mph with it going down hill and now I can easily go past 100+ mph with the 3.21 ratio I put in my full floating corporate 14 bolt

I love how at 6:52 you're hitting the hammer in tempo with the music lol

Tat was an excellent video break down on swapping gears. I've watched alot of videos on the subject but this one is very well done. Makes a guy feel confident in knowing he could tackle this project as well. Thanks

This video was in my recommended section and im not disappointed! Great video all around and for the quality I was surprised to see you have only 33k subscribers you definitely deserve more. Keep it up!

I remember an old timer teaching me how to set up a diff on a 90s C2500 in the oilfields. We took the diff out of the truck with a fork lift and basically did it in the dirt. Good times.

Hyped for this build. Can't wait till you button this up with painting the bed and finishing up the interior work.

I had a early 90s F450 superduty with 5.29s and ZF5 transmission. It was the same way even with overdrive. The 7.3 IDI was screaming at 65mph. But it was almost impossible to stall and would pull almost anything you put behind it.

Most informative auto channel on RU-vid from start to completion of project. With through explanations of each step along the way. Job well done Waldo. Looking forward to the bass expedition 🎣

Another great vid!! I lived in that part of NH for 8 years and I'm familiar with the highway you did your test run on. Brings back very fond memories!

I really like the fact that you explain everything so well. I never feel as though you lost me at any point.

You’re doing a heck of a job man! Keep it up, I love seeing you putting love into this.. Definitely one of a kind

Man, that truck is mint. The interior is sickeningly clean! I'm loving that pleated headliner bit and I just wanna say that your camera work is outstanding.

I dont know how I found this channel, but man I love it! Keep the videos coming! Great work, and very educational!

Really enjoying the channel. Keep up the good work. All those projects while outside in the heat and cold are an inspiration.

Another great vid. What I find most impressive is that you do all this work yet somehow you stay clean.

If you have access from the hitch on the bed. Place a hose from the hitch down to the fill hole put a funnel in the hose and fill from the top. Use the prescribed amount knowing it is empty. You then fine tune the level from there. It's just easier than doing it from the ground.

Great work here on this rear end.. I also don't have a lift and do these jobs on jack stands.. I really like how you built thus truck..it will be a tow rig for many years to come..great truck

Waldo this was a very interesting video. I am really looking forward to the finish coating on the new bed. Every Motörhead in the world is going to want this truck!!

Your choice of music when removing the pinion gear made me LMAO!!! Great Video, very informative, what a PITA! I like to put the race's in the deep freeze over night to make them shrink up a bit and a little easier to install.

very informative and well put together series. i have learned a lot. thank you!

Yep, top filming again ! Gearing seems just right , and yes love fishing to ! Thankyou Waldo !

You can do about anything!!!! I've had to rebuild a couple of rear axles because of bearing failures, and it's quite a job!

There's a truck just like that one, but a 1994 right down the road from me. Single cab, no bed, same mirrors for $1800. I also know where there's a 5.9 with an Eaton 5 speed already attached. The temptation to pull the trigger and bite the bullet is overwhelmed! Cool truck, BTW.

I don't own a car or know anything about how they work. But I watched the whole thing and enjoyed it.😅

excellent video and explanation of the rear end components and how to correctly install everything . Awesome truck Waldo .

Currently binging all your videos on this build! Love this Build!

That was quite an undertaking and you did great!! It’s definitely more drivable now. You really cracked me up with the amount of “dut duts” and the accelerated route. 🤣🤣🤣🤣 Seeing the big persuader come out over the nice nice too!! Go big or stay home!! Seriously tho, you make this so much fun with your personality and how great you explain what you’re doing. So much fun to watch. This is such a great build! Aspen is enjoying Billy Bob too! Such a great pup. The towing and fishing video would be great too. Thanks for sharing with us Waldo!

Thanks for put the links in the descriptions of things are a good tools

this is genuinely a great series please post more often btw the editing is on point

Waldo, just a heads up on those aftermarket diff covers ! Some are not the best choice . There is a good series on them put out by Gail Banks. You should watch if you have time. That was a great jump by Aspen ! My Dachshund Otis can jump jump just like that, up to 3 inches !!😂🌵

You can never go wrong with a big ass bearing separator. 😂 I’ve really enjoyed watching this build, cool stuff.

You win the award for "Best use of Anvil Chorus". I think Verdi would agree. (Although I don't think they had differentials as such in the 19th century.)

23:57 "who's my master talking to? Is he babbling to himself again?!" Great video, great content!

Fantastic video! Great work, when I do diffs I also like to use the old bearings for test fitment and see what shims to use that way I don’t mess up the fresh new one

That beat with the hammer was on point!

I love your work ethic. So inspirational. Keep it up, you're doing brilliantly.

I’ve been looking forward to this video. The Eaton Trutrac is an excellent choice.I can’t wait to see you pull a serious load with it the first time.

Great video my man keep up with the great work can't wait to see the finish product of what the truck will turn into 🙏💯

Eaton Trutracs are wonderful. While not a locker, they're a big improvement over open diffs. Quiet, strong and maintenance and uses plain old 80W90 with no extra additives.

Great video! Love to see your hard work pay off so nicely.

Such a good dog. I think somebody deserves a treat. Waldo, you don't get one until that steering wheel is straight.

Your truck looks so good with the filler pieces on the front wheel flairs. I love it.

Good job. A little old timer tip, when installing the cover, or pretty much any cover, some all thread in a few spots makes it cake to line up every time, especially in a fiddley spot like that. Run in the other bolts then pull out the all thread and finish. Works even better when lining up a gasket at the same time.

@6:50 - Your choice of music was perfect!! 😄

I still cannot believe how clean this truck is!

Well done, Waldo! Thank you for sharing.

Clicked on your video because i was curious about truck repair Stayed because of the easy to watch content, i learned a lot and the dog.

Great choice in gearing. With all the torque that Cummins produces, you're way better off using a higher gear ratio. It'll help a lot too on your fuel mileage. Great video Waldo!! 👌

This is absolutely great, that shifter is ridiculous, but I love it!

Good lord man! Your drive and patience are phenomenal! Great job!

I would be wary using the pinion bearings to press in the race, but if it works, it works! I am no axle rebuilder master, but I did it once in a Crown Victoria installing used junkyard 3.55 gears and a limited slip replacing the factory open differential with 2.73 gears. Didn't have the appropriate torque wrench to check proper preload on the pinion but I must have got it good enough, totally quiet, as I did use a new crush washer and did tighten it by hand to crush the crush sleeve. One of my friends did the same thing reusing the factory crush sleeve and his pinion bearings wore out - my job was moar better :D

really appreciated the polite "excuse me" after your massive fart! thanks bro!

Excellent vid Waldo, only started watching you a few days ago but am hooked. Greetings from England.

My god man, you are so smart and easy going with such complex repairs🎉.

Waldo, you are one intelligent, articulate, capable, experienced, and handsome young man. Not to mention an awesome youtuber.

I think you need an alignment! Awesome video man

You are the freaking man…. Just Waldo does it all!

Great instruction. You have an engineer's mind.

That music timing when knocking out the middle part is amazing

The clocking of that steering wheel would drive me absolutely bonkers!! Lol Great job though!!

So this is what Waldo's been doing since he's been since he's been found, heck man just giver the liver and drop a 10 speed in there

the music during pinion shaft removal was spot on!!!

very intensive task.. well done. Enjoy the real speed gain

Hats off. This is exactly what I would do to a truck like this. Down to the pleated headliner.

Now you need an exhaust brake on the Cummins.. You will enjoy the extra braking control while descending a hill or stopping a trailer load.. You can do the install yourself.. My wife and I did mine..

great filming, really appreciated

new to the channel and already a fan of the content and the style to present and explain everything.

Really good video! I’m glad the gear mesh turned out perfect. I think there is some sealant or a gland required for the pinion threads. I’m not sure because I have only dealt with 1/2 tons

I only found the channel recently but it’s the best car channel on RU-vid if you want to learn instead of just watch mindlessly

No matter what....that diamond tuck headliner has my vote 👍👍👍👍👍👏👏👏👏👏

You have an amazing ability to make me feel inadequate.

im hopefully gonna be buying a mid to late 80s c3500 and this build series makes me want to cummins swap it so much

Clear and concise, worthy of a sub!

Oh how much fun I have had with those same bearings and diff seals over the years...🤣

I just discovered this series at episode 26. So I guess I have 25 other episodes to binge now and get ideas from

What a job. Good work Waldo

Another youtuber i run into on my feed who is from the wonderful 603! Love the build man!

My OCD is kickin in HARD, with that steering wheel being all wop sided🤣 That Chevummins is sweet!

Splitting maul with that music was absolute gold my man.

You need to make a Waldo's World channel shirt that says "Click Click". I'd buy 2 lol. Love the build. Thanks for taking the time to make these videos!

This thing sounds so good. Amazing job again

I am amazed that you have the patience and fortitude to do all of that work, yet you have not gotten around to straightening the steering wheel yet. EDIT: nevermind, I just got to the point in the video where you directly address that issue. Lol. Good work!

The skill and patience needed to do this, is no less than a superpower.

I put my ring gear in a toaster oven and differential in shop freezer... 12:10, put a piece of hose on the spout, and prop the bottle upside down against the gas tank...

Pretty awesome. Funny I was getting ready to mention the steering wheel then you brought it up 😂

👍👌👏 Very well done again (video and work). Really nice dog. Thanks a lot for making teaching explaining recording editing uploading and sharing. Best regards luck and health to both of you.

Awesome edit. Glad to have found your channel

The thing I love about the Eaton true trac is that it’s a mechanical locker that drives fairly normal, AND you can just use regular gear oil with it.
