Pulley Shim Kit. This allows you align your Alternator , Generator, Dynamo , pulley with the lower Crank Pulley accurately. Also allows you align above pulleys to the tensioner pulley when using a Serpentine Belt System. Shims have cut out so the slip in over the wood ruff key making for easy installation/removal. On average you will need 1 to 2 shims on the lower pulley–fit these–then align the upper pulley as it is easier to get at.
Use a straight Edge to check your pulley alignment & avoid rapid belt wear & breakage
hint–always carry a spare belt
