450c rebuild

Post by 76450c » Tue Sep 09, 2025 2:05 pm

Have a 76 450c that I’m going through undercarriage, bought a parts dozer and swapping everything over. The two pieces that hold the mounting arms to the steering clutch housings are worn out on mine and perfect on parts dozer. I went to change them out but backing a hard time getting them out, any suggestions?

Not sure how to post pics but I have a bunch

This site requires using a third-party hosting site or set up an account for the dedicated picture server with Lavoy There is info about the server down below on the Messageboard Q&A and Announcements. The 13th thread down is about the site picture server. Postimage and Imgur are a couple third-party sites.

Are you asking about the mount brackets for the rear crossbar? I would expect those are rusted some. What do you have for tools you are using?

Big air impacts and pry bars lol, my real question is how do you get the brackets off without removing steering housings? They slide up and down the rear crossbar but either hit the track frame or transmission.

Come-a-longs, smoke wrench, gantry would all be helpful too.

Took the motor out, clutch is toast, how can i tell if i should change pressure plate also? Read manual but nothing readily mentions wear on pressure plate.
