Fluke 835 – Laser Belt Alignment Tool

It’s a known fact—all rotating machinery are susceptible to misalignment. An aligned pulley system reduces belt wear, power losses, and vibration of machinery, leading to improved performance. Still using wires and straight edges to ensure your belt-drive machines are properly aligned? You could be losing thousands of dollars per year in replacement bearing and belt costs, hours of unnecessary repair time, and crippling unplanned downtime, not to mention taking years off your machine’s useful life.

Alignment of belt pulleys in four simple steps

1. Initiate the Fluke 835 laser and mount the units on the faces to be aligned. The reflector should be mounted onto the machine to be moved (motor) while the laser transmitter is mounted on the stationary (driven) component.
2. The position of the transmitted laser line on the reflector indicates vertical angularity and offset. Horizontal angularity is indicated by the position of the reflected laser line on the transmitter.
3. Make adjustments while observing the laser lines on the reflector and the laser units:
   • Correct vertical angularity by shimming moveable machine observing the correction on the reflector.
   • Correct offset by shifting moveable machine axially observing the reflector unit.
   • Correct horizontal angularity by shifting moveable machine horizontally observing correction on the laser unit.
4. Genuine alignment is achieved when the transmitted laser line and the corresponding reflected laser line harmonize with their respective reference lines.
