Leaky Spool Seals On A Case Model 32 Back-hoe


Likely you can change the ones on the lever end, if it has bottom seals maybe or maybe not. You need to clean the valve well and see that the seals between the sections aren't leaking.

Should be a serial plate on the valve showing which one.

I'm no expert & I don't know how accessible the valve bank is, but the spool seals are basic O-rings, or a quad ring if specified, tho a backup ring may be needed if damaged. If you try to push the spool in to replace the lever end seal, you may damage the bore with the rough lever end of the spool. Best to remove the spool out thru the lever end.

This shows as a substitute for the basic O-Rings on both valves & I suspect the quad rings are the same size.

Like Jim said, clean & check for sectional seal leakage. Any leaks there mandates valve removal.
