Flattop Itm pistons.


Recommended Posts

I put a set of ITM flat tops in my L28 a few months ago.  only issue I had was tight wrist pins.  I probably caused the problem pressing them in with a 50 ton press  :rolleyes: .  They were nice and smooth prior to pressing them in.  I was worried about it so, I took them to a machine shop with a special tool specifically for this, it uses vey precise inductive heating and the wrist pins slide right in by hand.  didn't cost much, maybe $30.

As for the quality...They smash air well.
