looking to buy a 113 motor But
« on: February 13, 2018, 09:32:18 AM »
I'm looking to buy a 113" used evo. motor but it is polished which I don't want. Do you think a guy could media blast it to a satin finish while it's still together. I'd make block off plates for intake and exhaust to seal off but anything else other than oil pump and any other openings to the inside. What are your thoughts

I wouldn't sand blast it, one oops & you're done.
You may inquire about vapor blasting.

Sand you are talking a chance, it will screw up threads in any blind hole, walnut shell at low pressure will take off the shine. You are never going to get that cast look back. You could use steel wool to give it a brush look, or mild phosphoric acid will get rid of the chrome look and make it look milky, but bright. That is what is in Mag wheel cleaner for cast wheels.

Only so many ways something can get inside.
Ever since Harley decided to put covers over the valve springs on the knuckleheads, they've pretty much got the rest of the line isolated from the elements.

What type of media? Soda, its possible but its the sort of thing that would keep many up at night.

Seeing as its a used engine, have you considered simply disassembling it, having stuff treated however you want and reassembling it? I would. If for no other reason than to have a look and know there are fresh gaskets and seals throughout.

Yes, I'll probably just disassemble for reasons you mention. And I will be able to do a better job also.
