    Geith coupler disconnecting from rear bucket pin

    So I think I had a few problems, I pulled out the cartage inside the pressure control valve and it was in 2 piece (suppose to be one). And the seals were ruff. Since it was in 2 pieces, I ordered a new Danfoss 4SK303S3 Pulled the cylinder apart and the piston seal was missing a big section and...

    Hydraulic Cylinder Issue

    Doing a reseal on a large 115mm rod x 175 mm bore cylinder. The piston was stuck on the rod. There was foreign metal in the threads between the piston and rod not allowing it to unscrew.

    Volvo 330B LC dipper arm cylinder piston removal

    Just about all of the seals need replacing. So piston has to come off. Volvo claims they dont have any pistons available. Rod eye might not be a bad idea but since there's metal coming out on the piston side, it needs to come off otherwise there's going to be metal in the hydraulic system

    Hydraulic fluid change- ISO VG #46

    I'm the flat lander on the other side of TN. I looked them up and will have to give them a try next time I'm out that way. Use to go out that way several times a year but haven't been out there much lately. I thought I looked up the right one but maybe not. Either way, I can't find the HD LVZ...
