I recently replaced a bad hyd. Pump and it has worked great for a month. Today it started to lift slow and will not lift at all at idle I cked the pressure at tank and its fine 3900 psi. It acted like maybe a lift cylinder had went bad so I raised it all the way up and took the lines off one side at a time and no oil passing by the piston. It will raise from ground to full height in 10.5 seconds witch is 3 seconds to long but the tilt is 6 seconds. Any input would be great I'm thinking I need to go into the tank but don't want to till Im sure that's where I need to be. Thanks in advance first time user. George
