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. |
Note. Always check flywheel ring gear for signs of damage.
- Start engine while observing noise from starter motor. If a noise other than a loud, siren-like "whoop" sound is heard after engine starts, go to next step. If a loud, siren-like "whoop" sound is heard after engine starts, go to step 6 .
- If a noise other than a "rumble", "growl" or "knock" sound is heard as starter is coasting to a stop after starting engine, go to next step. If a "rumble", "growl" or "knock" sound is heard as starter is coasting to a stop after starting engine, go to step 4 .
- If a noise other than a high-pitched whine is heard while cranking engine, go to next step. If a high-pitched whine is heard while cranking engine, distance between starter pinion and flywheel is too small. Shim starter away from flywheel by adding shims one at a time and rechecking operation. Ensure starter-to-engine bolts are tightened correctly. See «TORQUE SPECIFICATIONS»(ref-8412-S26983478412000082800000) .
- Remove starter. See «STARTER»(ref-8412-S20000944892000082800000) under REMOVAL & INSTALLATION. Inspect starter motor bushings and clutch gear. If clutch gear shows signs of chipped or milled teeth or starter motor has worn bushings, go to next step. If starter checks okay, go to step 6 .
- Replace starter as necessary. During initial starter motor installation, shim(s) are not used. If shim(s) are present, install shim(s) in original location with replacement starter. Ensure starter-to-engine bolts are tightened correctly. See «TORQUE SPECIFICATIONS»(ref-8412-S26983478412000082800000) .
- Check flywheel ring gear for chipped, missing or milled teeth. Replace flywheel as necessary. See appropriate AUTOMATIC TRANSMISSION REMOVAL article in AUTOMATIC TRANSMISSIONS. If flywheel checks okay, go to step 5 .
