Inspect all 0R1570, 0R1571, 0R1572, 0R2861, 0R8915, 0R9393, 10R4401, 10R8409, and 10R8616 Cylinder Kits in dealer parts stock.

Inspect the package date code label on the outside of the boxes of these cylinder kits. (Image1) The first nine characters of the date code indicate the Day, Month, and Year. The last five characters (P68HL) indicate where the cylinder kit is sourced from. Determine if the date code falls in the range of D19M08Y11 through D21M08Y11 (19 August 2011 thru 21 August 2011),and (P68HL) follows these numbers.

If the source is not (P68HL), no action needs to be taken.

If the date code on the package is in the date code range of D19M08Y11 thru D21M08Y11 and (P68HL) follows these numbers, then inspect the piston pin on each end for a possible missing piston pin retainer. (Image2) If a retainer is missing, then install the required retainer. (Image3) Mark the package to indicate it has been inspected according to this program (PI7#####). Return the part to dealer parts stock.

If the date code on the package is not in the date code range of D19M08Y11 thru D21M08Y11, mark the package to indicate it has been inspected according to this program (PI7#####). Return the part to dealer parts stock.
