bryanf89 · 01-24-2010, 02:02 PM

I just got a set of lightweight pullies for my 7m engine. It came with the alternator, crankshaft, and power steering pulley. Does anybody know if the sell a lightweight pulley for the water pump in a 7mgte engine?

If your replacing a the crank pulley with a cheap ally one, you run the risk of damaging your engine. The heavy stock pulley is there for a reason, the weight of the pulley absorbs vibration from the crank. Links crankshaft torsional vibration. and resonance. If something rattles/vibrates place a heavy weight on the end of it.

Ive heard because our cranks are so long, a lightweight crank pulley can accually break the crank

On the crank pulley it does nothing to dampen/control vibrations. As Bill already mentioned, there's a reason the OEM units are heavy.
