SUBJECT: Incorrect Seal Used to Repair Leaking Pilot Valves On Integrated Toolcarriers, Track Type Tractors, Wheel Dozers and Wheel Loaders.
PROBLEM:
The cartridge assembly that is used in the pilot valve may leak. A change was made to the cartridge assembly that is used in the pilot valve. The former seal 7I-6601 was replaced by the
new seal 259-0509. There were other changes that were made to the pilot valve. Those changes were made to facilitate the assembling of the cartridge assembly when using the new seals. The result is that the new seal cannot be used for repairing leaking pilot valves where the 7I-6601 seal was originally used.
SOLUTION:
Do not attempt to install the 259-0509 seal onto one of the cartridge assemblies that are listed in table 1. To implement a permanent solution for this problem, serviceability will be eliminated for all of the internal parts of the cartridge assembly. If there are any 259-0509 seals in your inventory, we recommend that these parts be removed and discarded. Machines that have been repaired using the 259-0509 seal, we recommend that the customers is contacted to determine if the pilot valve is leaking and that the complete cartridge assembly be replaced when leaking occurs.
