I had read somewhere that the front pulley is too weak for handling a hydro pump. I just purchased a OC that has hydro problem with lifting the blade. What do I need to look for as it relates to the front pulley being weak?
The hydraulic pump does not run off the front pulley - I runs off the front of the crankshaft. I never heard of a weakness here - our's has a big pump in the front that ran a loader and backhoe.
Does the drive to the pump rotate? does it make a noise when it tries to lift? Do you have a pressure gauge?
