Flexible Couplings (Arr. 8 Only)

Check for misalignment between the coupling halves. Parallel and angular misalignment and separation gap are illustrated below. Refer to coupling manufacturer’s installation instructions for allowable misalignment and separation gap tolerances. When correcting for misalignment using shims, the shims should only be located under the motor. Do not place shims under the shaft bearings.

After aligning procedure, check for tightness of all coupling component pieces and ensure that they are clean from dirt and debris.

V-Belt Drives

The V-belt drive components, when supplied by Greenheck Fan Corporation, have been carefully selected for this unit’s specific operating condition.

CAUTION

Changing V-belt drive components could result in unsafe operating conditions which may cause personal injury or failure of the following components:

1.Fan shaft

2.Fan wheel

3.Bearings

4.V-belt

5.Motor

V-Belt Drive Installation

1.Remove the protective coating from the end of the fan shaft and assure that it is free of nicks and burrs.

2.Check fan and motor shafts for parallel and angular alignment.

3.Slide sheaves on shafts - do not drive sheaves on as this may result in bearing damage.

4.Align fan and motor sheaves with a straight-edge or string, and tighten.

Separation Gap

5.Place belts over sheaves. Do not pry or force belts, as this could result in damage to the cords in the belts.

6.Adjust the tension until the belts appear snug. Run the unit for a few minutes (see section on unit start-up) and allow the belts to seat properly.
