20. Install each piston and connecting rod
assembly into its corresponding cylinder, using
the piston ring compressor (special tool
P/N: 95550-002476) (Figure 5-149, (1)). Align
the pistons with the front mark arrow
(Figure 5-149, (2)) facing the front.
Note: Position the cylinder block horizontally to
allow easier installation of the piston and
connecting rod assembly. Install the
crankshaft pulley temporarily to keep the
crankshaft from rotating freely. Use
special tool P/N 119770-01090 and
119770-01120.
