Piston Ring: Testing and Inspection
1. Select a set of new piston rings, if necessary.
2. Use the following procedure to measure the piston ring end gap:
a. Place the piston into the cylinders at the bottom of the ring travel.
b. Place a piston ring on top of the piston.
c. Back off the piston.
d. Measure the ring gap. If the gap is below specification increase the gap by carefully filing off excess material.
CAUTION: High spots in the ring groove may be cleaned up by careful use of a point file. Do not attempt to cut the ring groove.
3. Measure the piston compression ring side clearance. Roll the piston ring around the groove in which it will be installed and measure the side
clearance. If the ring is too thick, try another ring.
