Well, I'm going to be soaking everything but the rotor housings in Simple Green, and since the Rotor Housings have aluminum on them, I have to find something that won't eat at it. What have you guys used to soak your housings in?

 

Acetone is one of the best solvents at dissoving a whole range of compounds, and it won't hurt aluminum or any other metal. Don't bother trying to clean metals that are already oxidized (or rusted in the case of steel/iron), since it won't dissolve metal compounds.

You can pick some up at home depot. Just remember to seal whatever container you put it in, and not with anything plastic. It will destroy plastics.

 

Yeah I just need something to loosen up all the grease and dirt.

And yeah I didn't even think of Acetone. We used to have like 6-7 containers, wonder if we still have any.

And damn, now I need to find something big enough to hold all this stuff. I do have a fishtank I'm not using, hahaha.

 

a bit of elbow grease always worked for me no matter than solvent used.

Use parts washer fluid and a brush. You can get this fluid at most parts stores in bulk.

I use "Gunk" brand parts washer fluid in a small parts washer to clean all engine stuff except the eccentric. Unless I suspect something is stuck in the shaft, I generally just wipe it down and put it somewhere safe.

 

kerosine (sp?)

 

Simple green says specifically not to use it on Aluminum parts, so it's a no-go on the rotor housings.

Aaron, I'll check out Gunk, I've heard of it before.

I'm probably going to go check out Purple power too, used to use that **** on my dirt bikes, works amazing.

 

Careful with the simple green or the purple power on the rotors. They will damage the bearings, but if you are going to replace them then go for it.

 

Yeah, if you don't care about the bearings that Purple stuff is awesome. It just eats carbon. I wouldn't soak housings in it though.

 

Yeah the bearings have a good amount of copper showing, so they're shot in my book. And one housing I know is bad, it has about a inch long scratch that's like 1mmx1mm deep/wide as well as a lot of flaking. But the other one looks good.

 

Copper showing is normal. The babbet coating is very thin and will wear off in high load areas fairly quickly. Measure the bearings before pressing them out because new bearings have more of a tendency to spin then the factory bearings.

throw em in your dish washer?
