Pulley Alignment Tool
When multi V-belts are used on the auxiliary drive system of a modern vehicle, it is important to ensure that all the pulleys are correctly aligned to avoid premature belt wear and ensure maximum belt life.
This new pulley alignment tool (part number 7644) provides an easy visual check of pulley alignment before fitting a new belt, comprising 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 (on the alternator or aircon compressor, for example) and tensioners. When the tool is set up in equal positions on the two pulleys being checked, you get instant visual confirmation of correct alignment, as well as an indication of parallel misalignment, angular misalignment and pulley runout, the last of which could be caused by a bent pulley or shaft, or by worn and damaged bearings.
The Laser Pulley Alignment Tool is typically priced at £78.02
