CONFIDENTIAL TIBU3989-03

The 3054E and 3056E engines use electronic Bosch fuel injection pumps. These are new engine applications for these pumps. Therefore, initially, Bosch is requesting that all failed pumps are to be replaced by new pumps from Cat Parts. Replaced pumps are to be returned to Bosch through Peoria, IL or Peterborough, U.K. as described below, depending on location.

Failed fuel injection pumps are to be replaced by new pumps out of Cat Parts. Pumps should only be replaced after a full diagnostic check of the Engine and Machine. Troubleshooting Guide, RENR2417, should be used in order to perform the full diagnostic check. Replaced pumps must be returned to Caterpillar Inc. for forwarding to the supplier for full failure analysis.

Pumps from NACD and LACD territories are to be packaged and shipped to:

Caterpillar Service Claims Room

8201 N. University

Peoria, IL 61615 USA

Attn: 3000 Series Engine Service Engineer

Pumps from EAME and APD territories are to be packaged and shipped to:

Perkins Engines Ltd.

Return Parts Centre-C/O Ron Chandler

Peterborough PE1 5NA

U.K.

All failure information is to be submitted with each pump. Dealers are requested to supply FULL details regarding their investigations into the failure of the pump. This information will allow for a more detailed analysis of the pump failure. Attach the normal service claim form. The following list represents the minimum amount of additional information that should be submitted with the faulty pump and the service claim form.

1. A breakdown of the fault finding process employed using RENR2417
2. Details of the failure including symptoms that were experienced (Hard to start, etc?)
3. Screen prints from Caterpillar Electronic Technician (Cat ET) describing both the logged and active fault codes at the time of investigation
4. Other relevant details from customers include engine and machine history and the usage at the time of the incident

Dealers from EAME should email the above information to Alex Radjenovic at Radjenovic_Alex@perkins.com

Dealers from NACD and LACD should email the above information to Robert Stoetzer at Stoetzer_Robert_A@cat.com

NOTE: All returned fuel injection pump ports must be sealed prior to shipment to prevent contamination. The protective caps used on the new pump ports MUST be transferred to the failed pump ports prior to return shipment to avoid contamination in route to the supplier. Also, it is imperative that the pump be protected against damage during transit. Damage during transit may prevent assessment by the supplier.

Dealers in the NACD territory are to follow the established parts return procedures per Service Warranty Bulletin No. 7.1.

Dealers outside of the NACD territory are required to pay for the shipping cost of the returned pump, then claim the shipping cost as a miscellaneous expense on the warranty claim.
