Put the ring into the bore, then use the piston to push it in about an inch (the piston will make sure its square in the bore)

if you have had the block bored and honed with a skirt clearence of 0.002" overall, jus fit the rings Correctley and fit the pistons, ....job done, the accralites are presision pistons and the rings are perfectley gapped

It is good practise to check them though. I always do, although if your boring man is good you shouldn't need to adjust the gaps.

However, I always bore my blocks 71.12mm on a +20 and the (O)megas are always or very close to a perfect fit. On 13th Jul, 2012 Ben H said:

Ring held in a softjaw vice one side of the gap, end of ring protruding very slightly above vice jaws so you can file it, but not protruding so much that you snap the end of the ring off.....

Gap between piston and bore measured at the skirt (ie, at or very close to the bottom of the piston) and measured at 90 degrees to the gudgeon pin (ie, front to back on a transverse engine). Schrödinger's cat - so which one am I ??? |

71.125 on the ring pack Bore the block to the MEASURED piston diameter PLUS the recomended clearance. Be sure to measure the piston correctly!! at the very bottom of the skirt, at 90 degrees to the piston pin. Use a micrometer, not a caliper. I do not care for what it says on the box. Measure it!

Why not phone where you purchased the pistons and ask them the recommended bore size and ring gap?
