jd 240 hyd. problem

[elkhntngmt]

240 jd brake will unlock releasing hydraulics and allowing skid steer to move no power on the left side right side and all othed hyd. work fine. I've had all the reliefs out on that side have not removed drive yet looking for suggestions when stick is moved all the way forward drive motor feels like it wants to engage will pull down motor a little

How is the pumps arranged? is it possible a shaft between the pumps has broken?
Can you swap drive motors from side to side to see if the problem moves? if it moves, its the pump.

The geroler just means the type of drive motor it is, not the brand name. The Geroler is the part of the motor that does the work. It has a centre start looking part with rollers that sit between the housing and the star.
Could a seal have not been put in correctly?
