C. Checking and/or replacing main blower fan belt

1. Check the main blower fan belt for proper tension and wear. To gain access you must remove the two (2) screws on the bottom lip of rear shroud along with the two (2) screws on the cooling fan guard plate.

Figure 4-32.

2. The fan belt should have no less than 1" deflection at the center and have no cracks or excessive wear. A spare belt is located inside the machinery compartment. Over tightening the belt will cause premature bearing failure and possible vibration problems.
