Easy multi V-belt pulley alignment check with Laser Tools

Multi V-belts are commonly used on the auxiliary drive systems on modern motor vehicles. It is important to ensure that all the pulleys are correctly aligned, to avoid premature belt wear and ensure maximum belt life. This new multi v-belt pulley alignment tool (part number 7644) from Laser Tools provides an easy visual check of pulley alignment. Use it before fitting a new belt.

This is a visual checking tool that comprises an alignment pointer and a marked alignment checking segment. These are designed to fit snugly into the V-grooves of the pulleys on the crankshaft, auxiliary components (alternator or air-con compressor, for example) and tensioners. When the tool is set up in equal positions on the two pulleys being checked (typically, two v-grooves in from the outer edge), looking down the straight, silver-steel alignment pointer gives an instant visual confirmation of correct (or otherwise) alignment.

The tool quickly picks up on common misalignment problems: parallel misalignment, angular misalignment (component not mounted correctly perhaps), and pulley runout, which could be caused by a bent pulley shaft, a bent pulley, or worn and damaged bearings. Again, the pulley alignment tool gives a clear visual indication of the amount of misalignment or run-out.

The multi v-belt pulley alignment tool is an EU Registered Design, and manufactured by Laser Tools at its Sheffield plant.
