Starter Motor: Service and Repair

A clashing or grinding condition may exist due to improper engagement of the starter to flexplate on some 1987-88 models equipped with 4.3L/V6-262, 5.0L/V8-305 and 5.7L/V8-350 engines with automatic transmission. To correct this condition, replace the starter drive assembly, with new drive assembly P/N 10456422, which utilizes a stiffer jump spring allowing for proper engagement. During starter drive assembly replacement, all ring gear teeth should be inspected. If three or more consecutive teeth are damaged, the flexplate should be replaced. Use flexplate No. 10128414.
