hi there joedorava
is there input to pumps , are there any leaks in the system either oil / air
have you purged all the air from the hydro units and wheel motors
if air is entraineed in oil , you may get alot of noise from caviatation in the pumps and wheel motors also heat , and vibration and no movement until all the air is gone
top up oil to correct level
caviatation can be quite destructive on pumps etc
i assume you used the correct hydraulic fluid for the unit in question
have you checked changed hydraulic filters when changed hydraulic fluid ?
other than that cant give any more info
