CAUTION
Damage Hazard: Do not open the piston rings too far. This will
cause damage to the piston rings.

Note: Make sure that you use tool (94338, Fig. 8) to install the piston rings.
1) Measure and record the thickness of the chrome-ceramic layer on each piston
ring. This will help you monitor the rate of wear during operation.
2) Install the bottom piston ring (4) to the piston head.
3) Install the middle piston ring (3) to the piston head.
4) Install the top piston ring (1) to the piston head. Make sure that the ring
clearance (5) is opposite the ring clearance (2) of the middle piston ring (3).
