Hello, I have a Terex 72-31B loader from around 1978-1982 (not sure) The machine has around 5000 hrs and runs well. The steering has a pretty severe binding/sticking issue. The loader steers fine if you steer very slowly, but if you spin the steering wheel too quickly it will lock up. Once it locks up, the only way to free it is to force the steering wheel in the opposite direction with considerable force. Because of this problem the machine goes down the road fine, but has trouble maneuvering around while loading trucks. This loader does have a large cylindrical accumulator under the cab on the curb side. Does anyone have any thoughts on this?
The early Terex loaders had problems like this. Does it bind up both ways or just one?
Thanks for the reply. It binds in both directions. Same conditions for either way.
Nut inside one of the cylinder s coming loose and binding ?
Not sure how to troubleshoot that without taking the cyl apart, or waiting until it gets worse. I was thinking that maybe the binding was happening in the steering valve under the cab? It is about 5" round and has four hyd lines coming off it. Where might I find a replacement for a machine like this?
