wooddude 0 #1 Posted April 14, 2009 I have a 1966 Wheel Horse Tractor model # 876 with a Sundstrand 5052 Transmission and a Hydrogear 3100077 pump. I am looking for a Implement Relief Valve for this tractor. This valve consist of a Spring and a Cone and is listed in the Wheel Horse Lift Kit HY-6 or 8-4111, 8-4112. The part # of the Cone is 6632, and the part # of the Spring is 6631. If you know where I can find these parts or have an old Hydrogear pump that has these parts, I would be interested in purchasing them . I would appreciate any help finding these parts, Thanks bOb Share this post Link to post Share on other sites
