Hi, I just replaced leaking lift piston rings on my Ford Jubilee and Case 480ck to fix 3 pt lift arms that dropped down over time. Easy enough fix although the Case lift cover was very heavy, and they work perfect now with no leak down.
The lift piston rings on my MF135 diesel must also be replaced as they are probably broken or worn as I took off the side cover and saw fluid leaking from the rear of the piston with a heavy load on the arms. The lift leaks down rather fast. No other leaks are detected.
I have the manual and read about taking out the roller pin and "to suitably retain the dashpot plunger to prevent it from dropping out when the lift cover is removed." Two issues:
1. What is the dashpot plunger and what does that mean about retaining it?
2. Any tips on removeal of the lift cover (i.e., can I lift it out by myself by hand, etc.), what to watch for, taking out the roller pin, getting the piston out of the cylinder, and then putting it back together?
