Operation sequence
1. Turn the prestroke actuator OFF.
2. Turn the camshaft as far as the No.1 cylinder's beginning of injection position.
3. Check that the pointer alignment mark of the injection pump and the alignment mark of the flywheel are matching.
4. If they are not matching, erase the alignment mark on the flywheel side, and stamp an alignment mark on the flywheel position that matches with the pointer side alignment mark.
5. Check again that the coupling's key groove position is in the No.1 cylinder's beginning of injection position.

1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully clockwise (viewed from the drive side).
Temporary tightening torque: 1 - 1.5 N.m (0.1 - 0.15 kgf.m)
2. Move the actuator in the counterclockwise direction when viewed from the drive side, and adjust so that it becomes the adjustment point of the adjustment value. Then tighten it.
Tightening torque: 7^9 N.m (0.7^0.9 kgf.m)
3. After prestroke actuator installation adjustment, simultaneously stamp both the actuator side and housing side.

Information:
This Program must be administered assoon as possible. When reporting the repair, use "PI30156" as the Partnumber and "7751" as the Group Number, "56" as the Warranty Claim DescriptionCode and "T" as the SIMS Description Code. Exception: If the repair isdone after failure, use "PI30156" as the Part Number, "7751" as the GroupNumber, "96" as the Warranty Claim Description Code, and "Z" as the SIMSDescription Code. The information supplied in this serviceletter may not be valid after the termination date of this program. Donot perform the work outlined in this Service Letter after the terminationdate without first contacting your Caterpillar product analyst. This Revised Service Letter replacesthe March 24, 2001 Service Letter. Changes were made to Parts Needed, ReworkProcedure, Service Claim Allowances, Owner Notification and Parts Disposition.

Remove the valve covers.
Using a medium to coarse flat file against thecup of the pushrod, stroke the file.
If the push rod is soft you will feel a distinctdrag as the file digs into the material.
If the push rod is hard the file will feel likeit is passing over glass as the file slides across the hard surface.
If you are not certain if a pushrod is soft orhard CALL YOUR TC OR THE CAT PRODUCT ANALYST AT:(800)447-4986.
If a pushrod is soft, remove the rocker arm andreplace the pushrod. Tighten the rocker stand bolts according to the torquevalue found in Service Manual.
IF A PUSHROD IS FOUND TO BE SOFT AND THE ENGINEHAS MORE THAN 200 miles (322 KM) OR 20 hours on it replace onlythe injector that is driven by the soft pushrod. Lubricate the two largero-ring seals with engine oil and install the injectors. Tighten the injectorhold down
