Recommended Puller

Lisle No. 45000 Steering Wheel Puller. This puller is avail-

able at most automotive parts retail outlets.

Drilled Hole Location

Wheel-to-Inlet Clearance

The correct wheel-to-inlet clearance is critical to proper fan

performance. This clearance should be verified before initial

start-up since rough handling during shipment could cause a

shift in fan components. Refer to wheel/inlet drawing for cor-

rect overlap.

Adjust the overlap by loosening the wheel hub and moving

the wheel along the shaft to obtain the correct value.

A uniform radial gap (space between the edge of the cone

and the edge of the inlet) is obtained by loosening the inlet

cone bolts and repositioning the inlet cone.

Troubleshooting

Problem and Potential Cause

Low Capacity or Pressure:

• Incorrect direction of rotation. Make sure the fan rotates

in same direction as the arrows on the motor or belt drive

assembly

• Poor fan inlet conditions. There should be a straight clear

duct at the inlet

• Improper wheel alignment

Excessive Vibration and Noise:

• Damaged or unbalanced wheel

• Belts too loose; worn or oily belts

• Speed too high

• Incorrect direction of rotation. Make sure the fan rotates

in same direction as the arrows on the motor or belt drive

assembly

• Bearings need lubrication or replacement

• Fan surge

Overheated Motor:

• Motor improperly wired

• Incorrect direction of rotation. Make sure the fan rotates

in same direction as the arrows on the motor or belt drive

assembly

• Cooling air diverted or blocked

• Improper inlet clearance

• Incorrect fan RPMs

• Incorrect voltage

Overheated Bearings:

• Improper bearing lubrication

• Excessive belt tension
