PROBLEM

The HEUI pump group needs to be inspected and may need to be replaced on certain 3126E Truck Engines. Interference between the control block and housing of the HEUI oil pump 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.

IMPORTANT: SAFETY NOTICE

SAFETY ? Recall for Inspecting and Replacing The Pump Group

MODELS INVOLVED - 3126E Truck Engines

Dear Caterpillar Product Owner:

This notice is sent to you in accordance with the requirements of the U.S. National Traffic and Motor Vehicle Safety Act and the Canadian Motor Vehicle Safety Act. Caterpillar has decided that a defect that relates to motor vehicle safety exists in trucks equipped with Caterpillar 2002 Model Year 3126E engines.

The injection oil pump on certain 3126E 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, which may result in a situation where a vehicle crash could occur. You will not be charged for the service performed.

Contact your local Caterpillar dealer immediately to schedule an appointment to inspect the injection oil pump to determine if it will need to be replaced. If it needs to be replaced, the dealer will replace it at no charge to you. The dealer will advise you of the time required to complete the inspection and replacement, if necessary. Please refer the dealer to their Service Letter dated December 1, 2002 when scheduling this service.

If you are a lessor of these vehicles, please forward this letter to your lessee within ten days.

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

If the dealer is unable to have the inspection and repair made, please contact:
