Measuring piston ring gap?

Post by Nemasys »

How do you measure piston ring clearance?

The specs say .008 inches per inch of bore or .008 mm per mm of bore

Bore size is 86 mm or 3.386 inches

I bought a feeler gauge that reads .008

I know the procedure you need to do, its the actual measurement im not sure about, just gap the ring at .008? Or do i have to multiply .008 x 3.386 which gives .027 inches? (.008 x 86 mm = .068 mm)

.008 seems awefully small to me!

I went out and measured the old rings as they were not damaged, the gap is .008 on the old rings, so i guess it's .008" afterall

This topic can be deleted. Thanks.

we'll it;s not that simple. you actually have to factor in your desired boost amount and open up the gap even more based on that.
