1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully counterclockwise (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 clockwise 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.

Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
Illustration 1 g06201989Certain Cat® Reman 3500 electronic fuel injectors may be marked with incorrect trim codes. Cat Reman 3500 electronic fuel injectors marked with trim code "2755" manufactured between 09 January 2017and 18 April 2017may be affected.The trim code is not correct for every injector. Refer to Illustration 1 for trim code identification. Serial numbers of suspect injectors range from (S/N: 1825569-1880788).Solution
Caterpillar is aware of this problem, but a permanent repair has not been identified. As an interim action, follow the below procedure:
All Reman 3500 electronic fuel injectors marked with trim code "2755" manufactured between 09 January 2017and 18 April 2017are suspect. Refer to Illustration 1.Caterpillar has created a tool which will help to identify injectors labeled with the incorrect trim code. Use the link below to download the file.https://cat.box.com/s/4fwh9nz0lwguh8vomifxj2rapqjc27e9
Enter the injector Serial Number in the spreadsheet downloaded. The spreadsheet will indicate whether the code is ok to use as is, or the spreadsheet will return the correct trim code.
Illustration 2 g06203882
If the trim code is incorrect, the injector must be relabeled. Use an engraving tool to cross out the original (incorrect) trim code (2755) and write the correct trim code on the injector tappet. Refer to Illustration 2.
Illustration 3 g06202000
Mark the box for each part that has been either reworked or verified to be correct, to identify that the parts are good to use. Refer to Illustration 3.
For individual injector replacements in engines, update the ECM with the correct trim code. Injectors must be marked with the correct trim code.Note: Do not return affected parts to Caterpillar. Use the procedure listed above to remark and use existing stock.Note: The issue has been resolved in the factory. Factory stock has been reworked and shipped. Parts in the distribution system are being sorted for return & rework.Note: Injector boxes have been marked with a large green dot to indicate that the injector has been sorted and marked correctly, or the trim code is correct.
