Installation
Before installing the piston, apply a coat of
engine oil to the ring grooves and cylinder
bores.
1. If the crankshaft is already installed:
• Guide the piston carefully to prevent damage.
• Fit long rubber hoses (about 30 cm (12 in) long) to
the connecting rod bolts to protect the crankshaft.
• Install the pistons after setting the crankshaft to
BDC for each cylinder.
• Install the piston assemblies in No. 1 and No. 4
cylinders. No. 2 and No. 5 cylinders, and No. 3
and No. 6 cylinders.
• Install the ring compressor, check that the bear-
ing is securely in place; then position the piston
in the cylinder and tap it in using the wooden
handle of a hammer.
• Stop after the ring compressor pops free and
check the connecting rod-to-crank journal align-
ment before putting rod into place.
• Install the rod caps with bearings, and torque the
nuts to 20 N-m (2.0 kgf-m, 14 Ibf-ft), then turn the
nut 116 degrees (see page 7-20).
