9. Tighten the pulley mounting nut.
10. Place the straight edge against the side of the muffler can.
11. Tighten the locknut to compress the restraining mount (snubber) until the top of the washer is aligned with the top of the gauge
bracket. Use straight edge to verify the top of the washer is aligned with the top of the gauge bracket.
Note: It is important to turn the belt as the nut is being tightened to prevent tension from building up in the belt.
Note: The washer on the restraining mount (snubber) should not go below the bracket side wall height. If it does, the
restraining mount (snubber) will be over-compressed.
12. Check the belt tension frequency using the frequency gauge P/N 204-1903 and adjust to the correct tension if necessary.
13. Reinstall the electric motor (jackshaft)/ compressor belt if it was removed.
Electric Motor (Jackshaft)/Compressor Belt - T-Series
The electric motor (jackshaft)/compressor belt is a polyvee stretch belt that also drives the compressor side evaporator fan and
the alternator. The alternator bracket has two adjustment steps, the factory setting and the field reset setting. A new unit is set at
the factory setting. At the first 2,000 hour service, it should be adjusted to the field reset setting. If the belt is replaced, it should
be set at the factory setting. After 2,000 hours it should be adjusted to the field reset setting. Use the following procedure to adjust
or replace this belt.
1. Loosen the alternator pivot bolt that attaches the alternator to the electric motor or jackshaft.
2. Loosen the locknut on the small bolt in the alternator adjustment bracket. This bolt is located behind the alternator adjustment
bolt.
3. If replacing the belt, loosen the alternator adjustment bolt to release the tension on the electric motor (jackshaft)/compressor
belt.
4. If replacing the belt, remove the old belt and note how it fits on the pulleys.
5. If replacing the belt, install the new belt. Make sure it fits on the pulleys correctly.
6. Tighten the alternator adjustment bolt until the alternator adjustment bracket is at the appropriate setting as follows:
• For the 2,000 hour service it should be set at the field reset setting.
• For a new belt it should be set at the factory setting.
• For the newer belts - tighten the alternator adjusting bolt until the top of the belt tension setting tool contacts the top of the
alternator adjusting bracket.
7. Tighten locknut on the bolt in the alternator adjustment bracket and tighten alternator pivot bolt.
