g. Installation.

(1) Apply clean engine oil (item 8, Appendix C) to the piston, rings, and inside of ring compressor.

NOTE

Inspect ring compressor for nicks or burrs, especially at the non-tapered inside diameter end. Nicks or

burrs on the inside diameter of the compressor will result in damage to piston rings.

(2) Refer to figure 4-36. Place piston ring compressor on a wood block, with tapered end of ring compressor

facing up.

(3) Position (stagger) the piston ring gaps properly on the piston.

Make sure ends of the oil control ring

expanders are not overlapped.

(4) Start top of the piston straight into ring compressor. Then push piston down until it contacts the wood block.
