name 3 piston ring checks to do before installing them?

Answer 1

With the ring in 3 different places in the cylinder with no piston, check end gap on the ring. With each (not oil ring) ring in the piston, the gap where the the ring fits in. And finally, the condition of everything.

Answer 2

Assuming the cylinders are properly honed with the correct stones check skirt to wall clearances carefully. Push one ring at a time into the cylinder bore using a flat top piston and check #1. End gap. #2. If end gap is in any way altered on a ring end gap hand crank cutter the top, bottom, ends and corner surfaces should be lightly chambered to do away with sharp edges. #3. Double check ring to piston land clearance. There's an outside chance the ring grooves may need to be cut to increase this clearance. If a ring is too tight in this area ring sticking may result as the piston heat up during operation. #4. Make sure the rings fully collapse in the ring grooves. The ring groove depths may need to be increased to prevent ring binding in bottom of the ring grooves. These steps should always be taken when fitting rings to pistons.

Answer 3

proper placement / make sure the on right and not upside down/ and check the gap between the open end of ring when compressed on the piston for proper gap / and to offset all the rings so that all the gaps dont line up to insure more compression

Answer 4

End gap.
Side play in piston grove.
Correct side up.

Answer 5

make sure they match, proper fit, and not bent
