I’ve been offering this service to local cub cadet, john deere and other sunstrand pump owners/collectors with 100% satisfaction. This “long overdue” service is now available to you. If your valve is leaking fluid you need to dismantle it to replace the seal. Until now when your cub cadet dealer/mechanic recommended that your relief valves need to replaced. Have your valves professionally rebuilt. That’s both valves rebuilt for only $74.95. Valve assembly part numbers ih-123481-c1, ih-123481-c2, ih-394872-r91, su-9500085. I have developed a machining procedure that allows me to dismantle. Replace wear items (o-rings and check valve spring), then reassemble without harming in any way the. Internal workings of the valve. Items used in the rebuild. 2 – stainless steel springs. 1- 7/16 grade 25 ball bearing. Ball seats are lapped (400 grid lapping compound) for a tight seal. Pictured are all the parts replaced from rebuilding a automatic style valve. Manual valves are the same minus one large spring. I just used the cub for the first time since installing the valve you rebuilt. The timely way the work was done, only took 8 days. From the time i mailed it til i had it back in my hand, the professional. The cost was just about 1/3 of what i would have spent, and 1/5 of a new one at the dealer! As i said i couldn’t be happier and will keep you in my file for future repairs.The item “Cub Cadet Auto or Manual relief valve REBUILD SERVICE” is in sale since Saturday, March 12, 2011.
