450B lugs and stalls when steering in reverse

Post by Les » Fri Apr 21, 2017 9:26 am

My 450B engine started lugging and stalling if I tried to turn while in reverse. It turns, but the engine lugs badly. Steering needs adjusted anyway, it doesn't turn right anymore. I was thinking it might be throw-out bearing or something like that. Ideas?

Sounds like the turning brakes are applying before the steering clutches are releasing. Adjusting might fix that. Seems odd that it does it in reverse but not going forward.

Sounds like lining on the brake bands out coming off the band and piling up between drum and band ...
