What is the purpose of a vacuum pump pulley?

A vacuum pump pulley is driven by the engine's accessory belt system. It spins the vacuum pump, which creates the vacuum needed for components like power brakes or to help with ring seal in high-performance engines.

What does the tooth count on the pulley signify?

The tooth count, like the 40 teeth on this pulley, determines the gear ratio between the engine's crankshaft pulley and the vacuum pump pulley. This ratio affects how fast the vacuum pump spins relative to engine speed.

Does this pulley come with a belt or mounting hardware?

This product is for the vacuum pump pulley only. You will need to ensure you have the correct size belt and any necessary mounting hardware separately to install it.
