I have an 06 exmark lazer z 60in. 27 hp. Been having problems with right side hydraulics. In forward and reverse the left overtakes the right. Originally swapped hydro pumps from side to side. original pump on right side I disassembled and found no issues other than little wear on valve plate. Thrust bearing, piston block, rear bearing etc. all looked good and tight. no leaks. Filled with oil and installed that pump on left side. Ck'd all linkage, belt and controls...all seem fine. Installed everything, new exmark hydro filter and exmark hydro oil.
Reclamped all return line hoses and bled system several times. No groaning from any pumps etc. No visible air or foam in reservoir.
release valves inspected and tight.
One thing I did notice with the engine off and the wheels off ground I can spin the right wheel motor by hand forward or reverse quite easily. I cannot spin the left wheel motor at all.
Possible bad wheel motor on right???? Shouldn't that right wheel have resistance, unable to rotate. Seems like the right pump release valve is loose or open...but definitely tight and o-ring seems fine. No leaks either.
I believe I got it bled out as the mower does move except for the left side dominance.
Any help/advice much appreciated!!!!!
