Question about a tractor with one domed piston

NickatKY · Jun 18, 2016

I have a friend working on a late model SC. When he pulled the head off it had 3 flat top and one domed piston.

Has anyone ever ran any tractor like this? If so did it run rough?

He's thinking about trying it.

Thanks Nick

Economics at the time. No doubt. We have all been there.

my thoughts exactly ,imho , it shouldnot matter much,on a SC . but the domed piston was engineered to deliver more h-power. the motor probably stops rite before that compression stroke of that domed piston ,.

I took the engine apart in a SC to find all 4 rod in backward. Don't know how long it ran that way.

I'm wondering also if it isn't a different diameter. The aftermarket domed pistons I have are oversized. Can't remember for sure, but I think they are 3-11/16".
