I have a old skid steer that about 6 months ago a press pin broke. I finally got around to replacing the pin and now I can't get it to suck oil to the one drive motor. Before the pin broke it was working fine. I've had the motor apart several times trying to figure it out. I've tried everything I can think of. Any help would be helpful.
Have you checked the hyd filter(s)? How about a crimped line???
Checked the lines and put a new filter on it.
