Pairing an Eaton Fuller Transmission with a 5.9 Cummins ISB [Part 5] 

Those are great recommendations, thanks! 👍

@@WaldosWorld that’s what I was going today too, it’s like a year old so I hope u did it

@@WaldosWorld - What is the model number for the Eaton gearbox you are using. Thanks

@@WaldosWorld - I am doing a 12v Cummins/Eaton Fuller into a '94 suburban project and so I need to ask the same set of questions. What is the model number for the Eaton gearbox you are using. What are the part numbers for the; bellhousing flywheel pressure plate clutch disc TO bearing etc. etc. Did you have to fab up your own clutch linkage? What bits and pieces did you use? I am not able to do the work myself so I finally managed to find a shop that has agreed to do the motor swap. However, when I mentioned grafting on a 10spd Eaton gbox to the 12v, everyone looked at me like I was deranged. I had to send your videos to the mechanic. So, if you could share the part numbers I would be most grateful.

I'm 4 years late but was about to post the same thing. Billet covers are nice but for a low dollar fix you can RTV the stock cover in place. The problem is that the stock gasket pushes out at high rpm when the crankcase pressure gets high. Gluing it on fixes this. I've done it on 2 600+ HP builds and haven't had an issue.

Thank you so much! I'm super excited for it too!

Thanks!!

Yes, that's the plan!

Thanks, Steve! Polo -- cool car!

Thanks, Scott!

Thanks, Pete! Yeah, I think I lucked out finding this medium duty transmission with all of the necessary parts for the swap for such a good price...it seems like it's hard to find a 5.9 Cummins with a manual in a medium duty truck, but there are a few out there!

Waldo's World unfortunately they all went automatic years ago but slowly coming back in the heavy haulers. I’m a huge fan of the 8LL and 18 speed transmissions.

Thank you for the sub!

Thanks for watching!

Thank you, I really appreciate the encouragement!!

Thanks, I really appreciate the feedback! 👍

@@WaldosWorld yeah, there are a few cars in the background we would like at least some backstory on, please.

Thanks!!

Thanks, cool name! 👍

Thanks, Carl! I have a dirt driveway and no concrete slabs (yet). It makes life difficult for now, but I plan on pouring a concrete slab in the barn so I have a place to work.

That's a good point you brought up. It prompted me to check the service manual to see if it required checking runout, but luckily, it seems like it's not necessary for this application

@@WaldosWorld i dont think Cummins does that at all on any of their engines ....

Oh nice! I'd love to have a GTD... if only they sold them in the U.S. 😢

@@WaldosWorld The Golf has been offered with a Diesel option here in the US since at least 99 maybe longer. I'm actually looking for a MK5 Golf TDI for my youngest son. We are a diesel family! 😁

Yeah, I can't wait until I have a nice concrete floor. It'll roll nicely on that!

Yeah, that's a really good point. I wonder if the previous owner replaced it when he did the clutch? Maybe (hopefully), since it's not leaking 🤷‍♂️

Thank you! You could probably make it work, but you would need an adapter to mate the Power Stroke flywheel housing to the Eaton bellhousing. You might be able to find something on the Interwebz since the Eaton uses an industry standard SAE 2 bellhousing

The flywheel is a Cummins 3977281 and the clutch is an Eaton 107621-7. As for the flywheel housing, just do a search for "5.9 Cummins SAE 2 flywheel housing" (assuming the trans you end up using has an SAE 2 bellhousing) and you should find some results

You are the man bro,thank you so much 👍

These came from the RU-vid music library. In order: Humidity - Silent Partner Hiiltop - Dan Lebowitz Rural Stride - Josh Kirsch

Wow, a 2006 with a manual? That must be rare! As for the swap, I bet it'll be a very tight fit. You'll probably need to plan on doing a body lift, but it'll be a very cool truck when you're done. Good luck!

@@WaldosWorld Thanks. Not many left around. More gears with an eaton fuller trans would be a perfect match.

I don't know for sure, but I assume it was a mid- to early-90's medium duty model. Those had 5.9 Cummins with the 5-speed Eaton

If the transmission has an SAE #2 bellhousing, then it will fit the flywheel housing that I have, though the flywheel housing that comes on Dodge trucks is different

Got it on eBay of all places 😂

@@WaldosWorld Is the bolt pattern for the bellhousing the same on the 6BT as the ISB? I would love to put an Eaton/Fuller in my 92 D250.

It's an FS-4205b 👍

I know, right? I've been getting some practice with the hoe, plus there's so much work left to do on the machine itself!

I actually have a two post lift that I picked up at auction, but I need a concrete slab to install it 🤠

Yeah, if it starts leaking, I'm going to regret not replacing it

@@WaldosWorld it looks like it already was leaking. i was surprised you didnt do it

Thanks! Mainly because the NV4500 that I have doesn't have a speed sensor or a parking brake (this application requires both). I stumbled upon this Eaton for a good price on eBay and it solved those problems, plus I thought it would make the project a bit more interesting 👌

@@WaldosWorld I watched your past vids and found out your reasoning. I'm gonna continue and catch up on your vid series, love watching them. Thanks for replying back so fast, you have a new sub and should have many more. Keep them coming.

Thank you so much! 🤩
