Gresen 2702 parts?

[59ih340]

I have a Gresen 2702 valve on my '61 IH 460 with a Windsor-Pippen loader.Anyone know where I can get seals and possibly spool springs for this?Also I really can't find any info (diagams/adjustment procedures).I just keep finding a lot of dead ends.but it seems to be a fairly common valve.
Thanks.

A local bearing supply house should be able to match the o-rings and seals (if any). McMaster Carr also has a wide selection of o-rings and springs. The springs will take a bit of measuring and trial and error, but you should be able to locate something close.
