I dont know what this is but it leaks hyd oil case 450 crawler loader

[Case450]

Case 450B crawler loader. I think this is a bucket leveling valve? It leaks pretty bad, is this something I can repair with some o rings or would a hydraulic cylinder shop be better to do it? I dont even really know what it is tbh

not a big job unless it has pitted seal areas you can just replace the orings , lube them after installing in their bores before assembly with hyd fluid but totally your call if you do not feel secure in doing it yourself, yes that is the hydro leveling valve, you do need to use the correct sized orings of course, sometimes they are not found in oring kits,,

I changed the one o ring on the cap, the old one seemed fine but when i reinstalled and tested it's leaking around that plunger/shaft. I'll remove and disassemble further and try 'er out.

Only found o rings where the hydraulic lines enter the valve body but its leaking where the plunger shaft exits the valve body, I threw an o-ring onto that plunger shaft and it did nothing to slow the leak. Im assuming I have wrong size o rings???
