Five spool hydraulic valve leaking.

[Fletcherkid]

I have a small industrial tractor that has a five spool hydraulic valve used to control the three point hitch. (Lift, pitch, tilt, remote, remote) Primarily the lift valve is used and is the first in the spool. Once the hydraulic fluid in the tractor warms up I get a steady drip from the bottom of the lift control. The cover that is over the spring at the bottom of the valve fills up and then continually leaks out all over the tractor. Bad for the environment, me and my wallet.

I have taken the valve apart and all the seals appear to be in good shape. I looked at a schematic of the valve and there are numerous parts and pieces that make up the valve. Any ideas or do I replace everything? They make you buy each piece separately.

You might try just the bottom o-ring on the bottom of the spool if there is one.
