This John Deere 450C Wouldn’t Move in Reverse… Until We Found

If your 450C dozer lost reverse or slips on a hill, this teardown shows exactly why — and how to fix it. We dig into a John Deere 450C forward/reverse transmission (reverser) a viewer hauled in. Reverse was slipping and sometimes went away on a bank. We tear it down, inspect clutch packs, find shot piston seals and cooked steels, and show the re-stack and snap-ring work. Parts were surprisingly in stock at the Deere dealer (~$500 here). No fancy tools—just a press (10-ton), puller, and a homemade 3" pipe coupling tool to compress cone washers. If you’re rebuilding a JD 450C (or similar), the stack order matters—get the book, mind the notched plates, and replace snap rings and seals.

It's expensive running machines, but the more you learn to repair yourself, the more satisfied you will be.🤙
