Campbell Hausfeld PU017001AV Air Compressor Motor Drive Pulley 3.45" OD X 7/8"

The Campbell Hausfeld PU017001AV Motor Drive Pulley 3.45" OD X 7/8" is an OEM metal pulley designed for specific Campbell Hausfeld air compressor models. It mounts to the motor shaft and transfers rotational power to the flywheel and compressor pump through the drive belt.

Common Issues:

• Belt slipping during compressor startup or operation.

• Excessive vibration from motor assembly.

• Unusual squealing or grinding noise from pulley area.

• Compressor running slower than normal due to incorrect speed ratio.

• Pulley wobble or uneven rotation on motor shaft.

Belt Slippage on Startup

Quick Check: Inspect belt tension and surface wear on the 3.45" pulley groove.

Fix Suggestion: Adjust belt tension and ensure correct belt size alignment with pulley groove profile.

Prevention Tip: Regularly check belt tension after installation and during routine compressor maintenance.

Pulley Misalignment Causing Vibration

Quick Check: Observe whether the pulley sits straight on the 7/8" motor shaft during rotation.

Fix Suggestion: Re-seat the Campbell Hausfeld PU017001AV pulley and verify alignment with compressor flywheel.

Prevention Tip: Always torque set screws evenly to maintain proper shaft positioning.

Noise or Squealing from Drive System

Quick Check: Listen for high-pitch noise during motor engagement.

Fix Suggestion: Inspect belt condition and pulley groove wear; replace if glazing or uneven wear is present.

Prevention Tip: Keep pulley groove clean from oil, dust, and debris buildup.

Pulley Wobble on Motor Shaft

Quick Check: Manually rotate pulley and check for lateral movement on the 7/8" bore fit.

Fix Suggestion: Tighten set screw securely and confirm correct shaft diameter match.

Prevention Tip: Ensure shaft is free from scoring or rust before installation.

Customer Experience: After installing this motor drive pulley, the compressor finally ran smooth without shaking the whole bench.

• Is this Campbell Hausfeld PU017001AV Air Compressor Motor Drive Pulley 3.45" OD X 7/8" compatible with standard Campbell Hausfeld air compressor motors?

  No. It is designed specifically for compatible Campbell Hausfeld compressor motor shafts that match the 7/8" bore size and correct drive alignment specifications. Always confirm shaft diameter and belt setup before installation.

• Why is my compressor still making noise after installing this pulley?

  Noise after installation is often caused by belt wear, misalignment, or improper tension rather than the pulley itself. Inspect the belt condition and ensure the pulley sits straight on the motor shaft.

• Can I install this PU017001AV motor drive pulley myself without professional help?

  It can typically be installed as a DIY replacement using basic hand tools. Ensure the motor is powered off, the pulley is properly aligned, and the set screw is securely tightened.

• What is the main function of this air compressor motor drive pulley?

  It transfers rotational force from the motor to the compressor pump belt system, helping control speed ratio and ensuring efficient air compression performance.
