Understanding Press-On Pulleys
This pulley uses a press-on (interference fit) design rather than a set screw. The pulley is pressed onto the motor shaft and held in place by friction. This design provides a secure, balanced fit when properly installed. Removal and installation require careful technique to avoid damaging the pulley or motor shaft.
Installation Tips
- Important: Press-on pulleys require proper tools and technique for installation
- Clean motor shaft thoroughly before installation
- Use a pulley puller tool for safe removal of old pulley
- Press new pulley on evenly to avoid cocking or damage
- Ensure pulley is seated at correct depth on shaft
- Check that pulley runs true without wobble
- Inspect V-belt condition and replace if worn
- Verify belt alignment after pulley installation
