Ok I`m replaceing the clutch and company, minus the flywheel. Can I clean the flywheel with carb. cleaner? And is there a way to determind if the flywheel is true and in good shape?

Thanks,

Roger

If it has swirls on it or any really deep grooves have it machined. Costs about $50. Or you can probably get a brand new one for $100 or so at a parts store, but I wouldn't trust it to stay flat very long. A Subaru flywheel costs around $250, so machining is usually the best option.

 

Otherwise, if the friction surface is smooth and one color(doesn't look like a rainbow, like burnt metal), scuff it up with some emery cloth and put it back in.

You should use brake cleaner to clean it. Otherwise you should have it machined so that you get maximum life from your new clutch. It would suck to only get 3/4 the life out of it if you didn't machine it. Good luck.

If your flywheel looks like:

 

 

You should have it machined. Just like having your brake rotors turned.

 

On my latest clutch job I replaced my flywheel with one from ACT, over 30k and just fine...

Ok thanks,

I also noticed when I removed the timing belt cover, on the block theres that black dus/oil stuff, where it coming from and what do I need to replace?

Thanks,

Roger

Black dust would be rubber from the belt. Nothing you can do about it really just clean it off and go about your business. If it is just a bunch around the idler bearings then it's just grease that they have flung out over time.

 

If there is oil it's from a seal somewhere nearby. Either one of the cam seals, or the front crank seal, or the oil pump seal to the block. There is also an O ring on the oil pump that likes to go bad. It also tends to get pinched if someone has removed the pump and reinstalls it with the old O ring.

 

Could also be a head gasket weeping. Generally those aren't worth bothering over unless it starts puking out of there.
