*Safety*	PRODUCT IMPROVEMENT PROGRAM FOR INSPECTING AND IF NECESSARY REPLACING THE HEUI PUMP GROUP ON CERTAIN C9 ENGINES AND D6R II MEDIUM TRACK-TYPE TRACTORS
7755		PI10211

NOTE: This Program must be administered as soon as possible. When reporting the repair, use "PI10211" as the Part number and "7751" as the Group Number, "56" as the Warranty Claim Description Code and "T" as the SIMS Description Code. Exception: If the repair is done after failure, use "PI10211" as the Part Number, "7751" as the Group Number, "96" as the Warranty Claim Description Code, and "Z" as the SIMS Description Code.

PROBLEM

Interference between the control block and housing of the HEUI oil pump on certain C9 engines and D6R II Track Type Tractors can cause failure of the high pressure O-ring between the block and housing resulting with the pump being unable to maintain pressure. This can result in a short period of rough running and subsequent engine stall due to loss of injection actuation pressure. Once engine stall occurs the engine cannot be restarted.

SAFETY - PRODUCT IMPROVEMENT PROGRAM FOR INSPECTING AND POSSIBLY REPLACING THE OIL PUMP

MODELS INVOLVED - CERTAIN C-9 ENGINES AND D6R II MEDIUM TRACK-TYPE TRACTORS

Dear Caterpillar Product Owner:

The injection oil pump on certain C-9 engines were assembled with out of print pump components and may experience a high pressure seal failure which can result in a short period of rough running and subsequent engine stall due to loss of injection actuation pressure. Once engine stall occurs the engine cannot be restarted. You will not be charged for the service performed.

Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service. Please refer the dealer to their Service Letter dated February 6, 2003 when scheduling this service.

We regret the inconvenience this may cause you, but urge you to have this service performed for your added safety and satisfaction.

Caterpillar Inc.
