I have a 5625sx GEHL with the Perkins 204-25 motor. I bought this skid steer not running for very cheap. The skid steer itself is in pretty good shape. After looking into it, what happened was the connecting rod cap for the number one piston rod failed. This caused the piston rod to come loose and locked the motor up. Surprisingly, nothing was damaged except the piston rod and crankshaft bearing. I was told by my local Perkins dealer that the 204-25 motor is obsolete, and he can't get parts for it. I managed to track down a set of crank bearing on eBay that work. But, I have been unable to find a piston rod. Does anyone have any advice for tracking down a piston rod or if I can't find one what motor could I repower the skid steer with, that would be fairly simple? Thanks for the help in advance.
