Troubleshooting Test Steps     | Values     | Results     |
---|---|---|
1. Inspect the Vibration Damper A. Clean any debris from around the damper. Check the vibration damper for damage. B. Inspect the mounting bolts for damage and/or for wear. Refer to the Disassembly and Assembly manual.     |
Damper     |
Result: The vibration damper or the mounting bolts are damaged. Repair: Replace the damaged vibration damper or the damaged mounting bolts. Result: The vibration damper or the mounting bolts are not damaged. Proceed to Test Step 2.     |
2. Engine Supports A. Inspect the mounts and the brackets while you run the engine through the speed range. Look for mounts and brackets that are loose and/or broken. B. Check the alignment of the following before operating the engine under load for any length of time: · Mounts · Coupling     |
Engine Supports     |
Result: The mounts and brackets are loose and/or broken. Repair: Replace the mounts and brackets that are loose and/or broken. Result: The mounts and brackets are not loose and/or broken. Proceed to Test Step 3.     |
3. Driven Equipment A. Inspect the mounting bolts for the driven equipment. Inspect the alignment and the balance of the driven equipment. B. Inspect the coupling.     |
Driven Equipment     |
Result: The driven equipment and the alignment are OK. Repair: Refer to Troubleshooting, "Engine Misfires, Runs Rough, or Is Unstable", for more troubleshooting information. Result The driven equipment and the alignment are not OK. Repair: Repair or replace the driven equipment.     |
