Note: Stop the engine before you check any belts. Open the access cover on the right side of the machine.
Alternator Belt
- Inspect the condition of the alternator belts. Use a Kent Moore Company BT-33-72C gauge to check the tension of the alternator belts.
The tension of a used alternator belt with more than 30 minutes of operation at rated speed should be 400 ± 44 N (110 ± 10 lb). The tension of a new alternator belt with 30 minutes of operation or less at rated speed should be 534 ± 22 N (180 ± 5 lb).
If the alternator belts require adjustment or replacement, proceed to Step 2.
