Combines combine won t move

sounds like your shaft_hub let go on the hydro pump up top. when they change out the shaft the new hub will have a grease zerk on it. good time to change your hyd pump belt when that hub is off. good luck

Chadh, I agree with crucut on the post below. When I was running 1688s I had to change that twice on one machine, and on the other one it never went out.

Just did 1688 coupler, shaft was damaged coming out of pump. Used aloy compound and put back together. Told this will hold it.
