I have the original service and parts manual, which has a nice exploded view drawing of the check valve group. I verified the correct assembly of the stabilizer thermal relief check valve and still the problem persisted. I then switched the check valve group from left to right and right to left and I still have the same problem of the left side cylinder failing to retract. Thanks for your quick response and advise. EB

I tried the suggested remedies from all of you, but unfortunatly, no luck. By the way, I neglected to mention that the machine has been sitting with it's left rear quadrant up in the air with an approximate 4" of clearance between the bottom of the tire and the floor. So, I decided to get radical. I jacked up the left rear axle just enough to neutralize the weight exerted on the stabilizer. I disconnected both hydraulic hoses from the cylinder, the check/stop valve and the thermal valve. I then tried to lower the stabilizer very slowly, but it still did not move. The machine still sits there with the left rear tire 4" off the floor. Thanks, EB

So, if I understand correctly you took the weight off the cylinder, then disconted the lines took out valves etc then tried to mechanically push the rod back into the cylinder and could not. If that is the case, it would seam that the cylinder is jammed in that position, like something came apart inside and wedged the piston. Correct??

I tried to push the piston into the cylinder by slowly opening the valve on my jack, which is supporting the left rear part of the machine. Unfortunatly, this did not work. I am now concerned that I may have distorted the cylinder in the process of removing the head nut, which was rusted in place. I had to use a tremendous amount of force to unscrew it. Thanks for your continued advise. EB

First and foremost, thank you all for your responses. The reason I removed the piston to begin with, was to have it refitted with new seal, packing, O-rings, back-up O-rings and rod wiper. All the components are brand new. I will try the suggestions that all of you made. Thanks again. EB

Could you have a blocked or collapsed hose. You could have a bad check valve as well.
