Blower Belt Adjustment — Inspect blower belt for wear, proper belt tension, and pulley alignment as conditions require or at the beginning of each heating and air conditioning season.

Make sure that fan shafts and motor shafts are parallel and level. The most common causes of misalignment are nonparal- lel shafts and improperly located sheaves. Where shafts are not parallel, belts on one side are drawn tighter and pull more than their share of the load. As a result, these belts wear out faster, requiring the entire set to be replaced before it has given maxi- mum service. If misalignment is in the sheave, belts enter and leave the grooves at an angle, causing excessive belt and sheave wear.

SHAFT ALIGNMENT — Check shaft alignment by measur- ing the distance between the shafts at 3 or more locations. If the distances are equal, then the shafts are parallel.

SHEAVE ALIGNMENT

1.To check the location of the fixed sheaves on the shafts, use a straightedge or a piece of string. If the sheaves are properly aligned, the string will touch them at the points indicated by the arrows in Fig. 9. Rotate each sheave a half revolution to determine whether the sheave is wob- bly or the drive shaft is bent. Correct any misalignment.

2.With sheaves aligned, tighten cap screws evenly and progressively.

NOTE: There should be a 1/8-in. to 1/4-in. gap between the mating part hub and the bushing flange. If the gap is closed, the bushing is probably the wrong size.

3.With taper-lock bushed hubs, be sure the bushing bolts are tightened evenly to prevent side-to-side pulley wob- ble. Check by rotating sheaves and rechecking sheave alignment. When substituting field-supplied sheaves for factory-supplied sheaves, only the motor sheave should be changed.

BELT TENSION ADJUSTMENT — Using a gage, apply 4 lb of force to the center of the belt and adjust the tension until a deflection of 1/64-in. is achieved for every inch of shaft center distance. See Fig. 10.

Ideal belt tension is the lowest value under which belt slip will not occur at peak load conditions.
