I picked up a 1992 Case 580SK backhoe. I need to flush the hydraulics. The plug I found is 1-7/8" socket. It is on the right side bottom of the main frame. Can someone tell me if I am on the correct bolt to drain the fluid. It is frozen.. Couldn't break it loose with a 3/4" breaker bar and a 4 ft metal extension. I am concerned about putting a torch on it for heat assuming I am on the correct plug to drain the Hydraulic fluid. There is the same size bolt on the opposite side which I am assuming is for the diesel fuel. Looks like the frame is used as reservoirs for hydraulic fluid on the right and diesel on the left. Any help would be appreciated. Any other places to drain the fluid?
Thanks
