STARTER NOISE
| CAUTION | Never operate starter for periods of more than 15 seconds. Excessive cranking can cause starter to overheat. Allow starter to cool for at least 2 minutes after each time operated. |
- A high-pitched whine, heard while cranking (before engine starts), indicates excessive distance between starter pinion and flywheel. If high-pitched whine is heard after engine starts and key is released, distance between starter pinion and flywheel is too small. Pinion-to-flywheel clearance should be.020 In (0.5 mm). (Scheme 6)
- If loud, siren-like "whoop" sound is heard after the engine starts, drive assembly is likely defective. If "rumble", "growl" or "knock" is present as starter is coasting to a stop after starting engine, starter armature is bent or unbalanced. NOTE: Check flywheel ring gear for damage.
- If diagnosis indicates pinion should be closer to flywheel, ensure proper starter motor was installed. During initial starter motor installation, shim(s) are not used. If shim(s) are present, remove as necessary.
- If diagnosis indicates pinion should be moved away from flywheel, add one shim. If using.039 In (1.0 mm) double shims, do not install more then 2 shims. If using.015 In (.38 mm) double shims, do not install more then 3 shims. If condition is not corrected, and pinion-to-flywheel clearance has been reached, single shims may be added to outer side of starter motor bolt using.015 In (.38 mm) shims. See STARTER under «REMOVAL & INSTALLATION»(ref-32833-S21923562852001011700000).
