L Profile Poly V Pulleys (8 rib)

Product Information

These pulleys are machined from a single solid and very heavy blank of metal, manfactured by our main suppliers in India they are machined with 8 L profile grooves and all are designed for use with an SK style of taper lock bush.

We have several sizes available from 10.25" up to a whopping 13" diameter with either 32mm, 38mm, 42mm and 48mm taper lock bushes (other size pulleys and bushes are available by special order only). The 10.25" weighs in at 21KG's and the 13" pulley weighs in at a massive 32KG's (weight figures approx).

Not only are these an efficient method of power transmission they double up as a serious flywheel mass adding to the smoothness of your power generation and helping to reduce light flicker problems. These have been machined from one solid lump of material with adding as much weight as possible in mind. A minimum of 2,3/4" or 70mm of shaft length is required to mount any of these pulleys safely.

You can see from the following series of three pictures how the general setup can be put together to effect a neat and efficient power transmission solution for a CS engine and alternator. The first picture on the right shows the bare pulley that has been mounted onto the alternator shaft using the taper lock bush system and it also shows the plain face of the engines flywheel the belt is going to be driven from. Both the pulley and the flywheel require good alignment to ensure the belt runs true and remains in line.

This second picture on the left shows the belt running on the engines flywheel face and alignment is maintained by the grooves of the pulley on the alternator. Whilst it is not necesary to have series of grooves cut into the flywheel face it is still essential to have some degree of good alignment, a belt will always find its happy running position so if the engine and alternator are not aligned fairly well your belt will simply slide off the flyweheel face when running.

This last picture shows a closer view of the poly V belt mounted onto the pulley at the alternator end. We hope to add other sizes in the future so if you need a size not listed please do let us know.
