Termination Date

Problem

Some of the 9Y6188, 9Y7735, 9Y9497, 4W5739, 4P8167, and 1193782 engine connecting rod bearings may experience "flaking or sheeting" of the outer overlay material layer.

Action Required

Inspect all 9Y6188, 9Y7735, 9Y9497, 4W5739, 4P8167, and 1193782 Engine Connecting Rod Bearings in Parts Stock which have a package label date between "010699 (01 June 1999)" and "310100 (31 January 2000)" and a supplier code of "A9706X0 or A9706X1". The format for the package date is "DDMMYY". The example in Illustration 1 is for a bearing packaged 061199 (06 November 1999) with supplier code A9706X0, which is within the date range of concern.

Illustration 1.

While wearing gloves to avoid "finger printing" of the bearing, packages with supplier codes of A9706X0 or A9706X1 AND with label date codes between 010699 and 310100 (Illustration 1) should be opened. Bearings inside these boxes with the plating month codes .GG, .GH, .GI, .GJ, .GK, or .GL must be removed from Parts Stock. The plating year code should be DD (1999). The format for these plating codes is shown below (Illustration 2).
