STARTER NOISE/FLYWHEEL DAMAGE NEW STARTER DRIVE ASSEMBLY

1985-86 GRAND AM WITH 3.OL ENGINE

A new spring cushioned pinion starter is now used on all 1986 3.OL and 3.8L transverse mounted engine applications. The machined pinion and cushion spring wave washer design provides smoother engagement and reduces flywheel damage, especially flywheel milling.

Service drive assembly, part number 10498407, replaced 1984511 on current and past model applications. The new drive assembly should also be used when rebuilding starters for listed applications.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
