Crankshaft pully grinding
Well I noticed a noise under the hood and seen that my crankshaft pully is starting to grind away at my center timing belt cover. I watched the pully closely and it doesn't look bent and the cover is one tight. Any thoughts?

Re: Crankshaft pully grinding
Harvey is right,
Mine was doing it for a year.... lol Got another one from SubaFreak and replaced it just yesterday... lol Did my ACC belts at the same time. took about 1hr total and cost about $65, including the belts from Subaru.

Re: Crankshaft pully grinding
That's what I was afraid of. Well I guess it's time for a lightweight pully and a new timing cover. Thanks.

Re: Crankshaft pully grinding
A new lightweight under-drive might or might not be a good idea. Didn't work for me.
(I know, light weight doesn't necessary say under-drive but there are some choices) Just a thought. Keith |

Re: Crankshaft pully grinding
There are TONS out there. Any for the current H-4's work. Don't cheap out and buy a $35 piece of crap one though, chances are it won't be perfectly balanced and you'll have a noticable vibration at certain RPM's. Spend some money, get a good one, and you'll thank yourself later on.
Click here for a selection of some of the pulleys available.

Re: Crankshaft pully grinding
Underdrive is a term for a slightly smaller than stock pulley and there are underdrive pulleys for the a/c, alternator, etc but most commonly used for the crank pulley-less weight allows the engine to rev faster. It also can allow for a few extra horsepower.

Re: Crankshaft pully grinding
It also means that in certain driving situations the alternator may not produce enough current to provide use of electrical components and keep the battery charged... like parking on the freeway for hours in traffic conditions in Seattle Tacoma area.
