Information:
The information supplied in this service letter may not be valid after the termination date of this program. Do not perform the work outlined in this Service Letter after the termination date without first contacting your Caterpillar product analyst.
If the work described in this Program was performed on the Affected Product under PI7298, Service Letter dated October 30, 1992, DO NOT repeat the work.
This Revised Service Letter replaces the April 28, 1993 Service Letter revised March 1994. Changes have been made to the TERMINATION DATE and Affected Product.
Termination Date
August 31, 1994Problem
The fuel injection pumps used on certain Remanufactured 1160 and 3208 Engines need to be inspected for gummy deposits.

Parts Stock Remanufactured Fuel Pump Part Numbers
This program applies only to pumps in parts stock with a date code prior to November, 1993 (UUDE). Date codes are in the MM/YY mode with the standard notation of NUMERALKOD.
Parts Needed
Not applicable.
Action Required
Before installing or delivering any of the Affected Product, perform the following steps to ensure the internal fuel injection pump components are not stuck due to fuel pump gumming:
1. Remove the top cover of the fuel injection pump and check to ensure that all sleeves and levers are free and there are no gummy deposits on any of these components.2. If inspection performed in Step 1 indicates everything is clean, install top cover and return to parts stock.3. If inspection reveals components have gummy deposits, remove 12 ounces of fuel from the fuel pump housing and replace it with:- Fuel Injector Cleaneror- Carburetor/Choke Cleaner4. Allow the components to soak in cleaning solution for 45 minutes. Then, rotate the engine crankshaft to rotate the fuel injection pump and check for free movement of the lever and sleeve (on pumps only, rotate the fuel pump camshaft). This will ensure the components have the gummy deposits removed.5. If the above procedures do not free the pump assembly, remove the individual pumps from the pump housing, clean them with cleaning solution, and install them back into the housing.6. If the engine or fuel pump will be used immediately, install the cover on the fuel injection pump, and install or deliver the engine or pump.7. If the engine or fuel pump will be returned to stock, DO NOT leave the fuel injection pump full of cleaning solution because it may not contain any rust inhibitors. Remove the cleaning solution, fill the fuel injector pump with clean diesel fuel, and install the cover on the pump.Service Claim Allowances
The inspection of the pump is a .5-hour job. If the pump needs to be cleaned, an additional .5 hour may be claimed. If the individual pumps need to be removed from the pump housing for cleaning, up to an additional 1.5 hours may be claimed.
US and Canadian Dealers Only - When submitting a Parts Stock claim use 99Z00007 in the Product Identification Number Field.
Parts Disposition
Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.
