belt ear. Belt wear may be indicated by belt shavings or dust in the engine compartment in the area of the belt, and by inspecting the belt as shown in Figure 1.

This wear may be caused by movement between the outer ring and inner hub of the crankshaft damper assembly. This condition can be identified and repaired using the procedures listed in this bulletin.

Note the position of the timing pointer relative to the outer rin/pulley of the torsional damper (see Figure 2).

Figure 2 - Correct and incorrect relative positions of the timing indicator to the outer ring/pulley.

If the outer edge of the timing pointer is in the incorrect position as shown in the right portion of Figure 2, check the damper assembly by removing the right wheel inner splash shield. The faces of the inner hub and outer ring/pulley should be approximately flush (see Figure 3).

If a difference of 1/8" or greater can be seen, or if the alignment marks indicate movement between outer ring/pulley and inner hub, the damper assembly should be replaced with p/n 14102596 following the procedure in Section 6A3 of the 1985 Cimarron Service Information Manual.

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.
