So before i put my pistons back in...of course i have to do the pin bushings and bearings and rings...i know to use part of the old rings to clean the ring bases...but what about the side of the piston...theres pretty much carbon built up around the entire circumference on almost all of them... in between the rings and down to the oil rings. plus the tops of course...how should i clean the sides? let alone the top?

 

use an old ring to clean out the ring grooves

for the top, I know you can use a scotchbright pad, but I'm not sure about using that on the sides

DON'T USE A SCAPER OR FLAT-EDGE RAZOR THOUGH, THAT'S A NO-NO FOR SURE!!!



I didn't even bother during my rebuild... for the price, I just put in new ones from engnbldr

 

brass wire wheel and lye (hot) (or oven cleaner- just make sure to follow the directions) for those hard to clean things.

 

what about a brash brush? i have that.. and brake cleaner haha...

 

eh, I don't know that I'd want to use a wire wheel on the skirts of the pistons...

the tops either...


the FSM says not even to use a wire brush!

 

yeah, i was trying to use brake cleaner and rags...but thats just wasted time....my bud said to get some diesel gas and soak the piston heads in that for a while...would that work?

 

eh, I guess you can use a gasket scraper on the top anyhow... but I'd be VERY careful...

 

Brass is one of the softest metal alloys. Works great for cleaning other metals... when used as a wire wheel.

 

they still dont have a picture or something specific for the sides... whats the solvent?

 

I think I said:
