long tractor hydraulics

Posted by wayne plotts on April 02, 2005 at 08:21:21 from (64.136.164.50):

Can anybody offer some suggestions?
Here is the problem we have. We have a Long 445 that pumped all of the hydraulic fluid into the crankcase. We thought that the only way that could happen is a shaft seal failure on the power lift hydraulic pump. We overhauled the pump which included replacing the shaft seal. After using the lift for just a short time the same thing happened again- it pumped all the hydraulic fluid into the engine.
The power lift operated erraticly, that is it would lift a couple of times and then quit. We would bleed the system by cracking a fitting and it would work again for awhile.
It also has a separate pump for the power steering but there is no indication that either of these pumps has leaked around the shaft seal.
Any information would be appreciated.
Thanks,
Wayne Plotts
