Belt Hog Pulley Alignment Tool

Squealing, shaking, out-of-line belts and pulleys are more than a nuisance. They're the cause of expensive downtime, shortened equipment life, and inefficient operation. If you ever have those problems, it's time to holler for the Belt Hog.

Accushim's Belt Hog makes it simple to align belts and pulleys. You won't have to remove the belts to make quick, accurate adjustments over distances of 6" to 20 feet. One person can accomplish an alignment with no training other than reading the short instruction manual.

Belt Hog mounts in the grooves-right where the power is transferred. Groove mounting makes it simpler to keep everything parallel. Belt guards can often be left on, and pulleys on shafts set in different directions can be aligned just as easily. Bright dual LASER beams let you know when you've got things straight.

By adjusting the pulleys so that the laserline coincides with the reference line on the opposite LASER unit, the pulleys are aligned. Mounting of the Belt Hog units Each unit is mounted on the pulley as shown in the diagram below. Note: The magnets, which holds the unit to the pulley, are very strong. Do not pinch your fingers!
Position both units with the spring action probes resting in the same groove on both pulleys and the units are facing each other as shown below.
When the units are mounted, turn on the LASERS. Each LASER generates a line on the opposite unit. When correctly aligned the lines coincide with the reference marks on the labels on both units. If the belt transmission is mis-aligned, start by correcting the angular error.
It is important that the pulleys are mounted correctly on the shafts and that the shafts are straight before starting the alignment process. Wobbling or warped pulleys affects the alignment quality severely. Safety The Belt Hog uses LASER diodes with a power output of less than 1.0 mW. The LASER classification is Class 2, which is considered safe for its intended use with only minor precautions required. These are:

  • Never stare directly into the LASER light source.
  • Never direct the LASER into anyone else's eyes.
