ASSEMBLY - Continued
3.
Piston and Connecting Rod Assembly to Cylinder Liner.
a.
Apply clean engine oil to piston, rings, and inside surface of piston ring compressor.
CAUTION
Inspect piston ring compressor for nicks or burrs, especially at inside diameter of
straight end. Nicks or burrs on inside diameter of piston ring compressor will result in
damage to piston rings.
b.
Place piston ring compressor (Figure 12, Item 30) on wood block, with larger end of piston ring
compressor facing up.
CAUTION
Piston ring gaps must be 90 degrees apart on piston for proper compression. Ends of
oil control ring expanders must not overlap or breakage will result.
c.
Start top of piston and connecting rod assembly (Figure 12, Item 8) straight into piston ring
compressor (Figure 12, Item 30). Then push piston down until it contacts wood block.
d.
Place liner (Figure 12, Item 1) with flange end down on wood block.
NOTE
Numbers on side of connecting rod and cap identify rod with cap and indicate
particular cylinder in which they are used.
e.
Place piston ring compressor (Figure 12, Item 30) and piston and connecting rod assembly
(Figure 12, Item 9) on liner (Figure 12, Item 1) with numbers on side of connecting rod and cap aligned
with matchmark on liner.
CAUTION
Do not force piston into liner. Expanders apply considerable force on oil rings;
therefore, exercise care during loading operation to prevent ring breakage.
f.
Push piston and connecting rod assembly (Figure 12, Item 9) down into liner (Figure 12, Item 1) until
piston is free of piston ring compressor (Figure 12, Item 30).
g.
Remove connecting rod cap (Figure 12, Item 7) and then remove piston ring compressor
(Figure 12, Item 30) from piston and connecting rod assembly (Figure 12, Item 9). Push piston down
until compression rings pass cylinder liner ports.
h.
Repeat Steps 3.a. – 3.g. for remaining pistons and liners.
