Cleaning block an pistons w/ brass brush (83 GL1100)

Postby velvetrider » Sun Aug 30, 2015 11:06 am

I am in the process of new head gaskets job. I am having trouble getting it "CLEAN". Break cleaner and tooth brush gets me just so far. I can not get that "Super clean" the posts and U tube talk about.
I know better than to clean heads with mechanical, anything. How ever I was thinking that the block and pistons tops would not be injured using a brass brush.
Also the Honda manual says not to move the engine from TDC where I marked and removed the Timing belts. I can not get to # 3 & 4 pistons in this position. Everything is marked, belt, teeth.
What would be the harm? Any thoughts on these would be helpful. :?

I used a brass brush attachment in my Dremel at low speed when I did mine. If you do this, a faceshield (preferred) or safety glasses are an absolute necessity....those Dremel wheels shed wires like'll find them in your hair hours later. I'm sure that I turned my engine over to get to #4 piston (the one with the gouge from the screw that bent the intake valve). As long as you get it back to exactly the same spot, no problem.

Brass is ideal. It is a softer metal than the heads and will give you what you want. I use brass brushes quite a bit, very satisfactory results.
