Introduction

The problem that is identified below does not have a permanent solution. Until a permanent solution is available, use the solution that is identified below.

Problem

Illustration 1	g02934325
Properly installed piston pin retainer

Some reports have been made of cylinder packs with missing piston pin retainers.

Installation of a piston that is missing a pin retainer could result in severe engine damage.

Solution

Examine the date codes on the packaging labels of inventoried parts that are listed in Table 1.

A date code is printed with "D" for the day, "M" for the month, and "Y" for the year. The day, month, and year are represented by two-digit numbers.

The date code of "D01M03Y12" is for 1March 2012.

Any package with a date code that precedes "D01M03Y12" is suspect.

Inspect the contents of packages with a date code that precedes "D01M03Y12". Make sure that both of the piston pin retainers are properly installed.

Note: Only inspect cylinder packs that are scheduled for installation.

Report any cylinder packs that are missing a piston pin retainer to the Reman Technical Help Line at the following telephone number:
