Here are some pictures of the fitment of the commercially available seal drivers. It's close... but almost completely ineffective since the aluminum adapter plates want to drive the seals from their inner rubber parts vs outer metal. They are, however, much more economical than having a fab...

Started reinstalling hubs and EcoHubs today ! The seal drivers available on Amazon/Napa aren't an exact fit, but the TMs have diagrams of how to make the perfect seal driver. I split the middle and 3D printed some adapters for the commercially available metal ones (after getting $200-400 quotes...

Been wire wheeling, parts washing, rust converting, priming, and painting like a mad man. Basically have all 4 hubs at some stage of progress right now ! Milwaukee M12 die grinider is the MVP of this part ! I'm pretty sure whole sunflower seeds are not supposed to come out of Central...

I keep hearing about "zero mile resets" on FB and other groups... not sure what all that entails, but it's quite possible this truck had one done. There was a 2019 rebuild tag on the transmission, now all 4 corners have new brakes and freshly packed wheel bearings+new looking CTIS & axle seals...

While I was painting those, I also started pulling the hubs. Figured 23yo truck... probably needed some love in the wheel bearings department, but actually looks very recently serviced... unfortunately they packed both the hub oil side AND other side with grease. Which explains the almost...

And for an actually interesting/exciting update, I started on what I thought was going to be one of my first projects, regearing the hubs with EcoHubs ! I 3D printed some blockoff plates since all 4 would be the same, red scotchbrite sanded them (unfortunately in the 14mo of them being in my...

Been a couple months since I last updated, but I have been busy ! With work, life, and the truck. I got the air brakes sorted out and successfully test drove it 2 weeks ago ! For anyone else reading this thinking of, or having removed, the AOP and manifold on an A1: 1. Remove the Red line -...

I ended up having to idle the truck with my airlines open/venting after the manual hydraulic conversion... I traced the lines; the smaller 1/4" line for cab air suspension goes to the wet tank on the side, but the bigger 3/8" air line for the (now removed) Air/Hydraulic Pump Unit goes to the...

This past weekend I got the valve body/pan back on the truck (what a freaking exercise in tedium that is !) and did my best to flush out all the water contaminated fluid. I pulled the return from the cooler and let that pump ~7gal of fluid into 2x buckets before the fluid turned a more normal...

Where did you get the original 3d printed model from ? That looks great. Would love to print an M1078

Well, everything in NC shut down for the snow so I was able to make some decent progress and got the valve body back together.

Sidequest: Several friends have pitched in to help work on the truck, or been especially helpful (Allison dealer, for one) so I made this little plastic token as a Thank You. It's double sided with the Aviator4x4 logo on the other side. Plan is to update the design as the truck gets painted or...

Got the new composite thrustwasher installed, reinstalled the C6 clutchpack in the housing, lined up the snap ring to satisfy my OCD, and got the housing re-installed with 19 new bolts and 1 re-used torqued to 45-55ft-lb. It went surprisingly smooth considering it's basically a 55# overhead...

Interesting idea. I think I might ! Did you use regular JB weld Cold weld or something more exotic ?

Feeling better about my hypothesis of where the water came from. It rained here yesterday and I could see a waterline/drop on this dry rotted filler seal: Really hope that is the cause. I can't see any other plausible points of ingress; the breather cap on the top of the trans is in good...

Haha yeah... the seemingly endless rabbit hole of transmission problems with this truck strikes again. Discouraging but I just keep holding on to the vision of what I want to build the truck in to. Hopefully I can achieve it with a lot of luck, little bit of skill, and no experience :LOL...

While I'm waiting on parts from Allison, I figured I would tackle the corner bolt issue which was so, so much worse than I thought it was haha. When I removed this shorter, yellow zinc coated bolt... A section of aluminum threads came out with it. As seen here, with an original transmission...

Hopefully you got an answer, but found this in the sealed white envelope with all the gaskets

Yessir, planning on pulling the return and letting her pump out as much as she wants. Flush is some liquified money AMSOIL engine+trans flush. I selected it since it's advertised for both engine and trans, and is an EG based product which is hygroscopic/miscible. I'm hoping a combination of...

Hopefully this transmission thing isn't the end of my story ! I believe I have ordered all the parts needed from my local Allison rep to get it back together, but who knows how long they'll take to get in (one is probably backordered, or something). Once I have everything in my hand, I think...
