CRANKSHAFT
TIP
• Align the projections “a” on the balancer big
end bearings with the notches “b” in the bal-
ancer connecting rod and balancer connecting
rod cap.
• Be sure to reinstall each balancer big end bear-
ing in its original place.
• Make sure the “Y” marks “c” on the balancer
connecting rod face towards the left side of the
crankshaft.
• Make sure the characters “d” on both the bal-
ancer connecting rod and balancer connecting
rod cap are aligned.
6. Tighten:
• Balancer connecting rod nut
TIP
Tighten the nuts to the specified torque. Apply
continuous torque between 30 N·m (3.0 kgf·m,
22 lb·ft) and 60 N·m (6.0 kgf·m, 44 lb·ft) without
pausing. After reaching 30 N·m (3.0 kgf·m, 22
lb·ft), do not stop tightening until the specified
torque is achieved. If the tightening is interrupted
between 30 N·m (3.0 kgf·m, 22 lb·ft) and 60 N·m
(6.0 kgf·m, 44 lb·ft), loosen the nut to less than
30 N·m (3.0 kgf·m, 22 lb·ft) and start again.
7. Install:
• Balancer piston “1”
• Balancer piston pin
• Piston pin clip “2”
TIP
• Apply engine oil onto the balancer piston pin.
• Make sure that the clip ends “a” are positioned
away from the cutout “b” in the balancer piston
as shown in the illustration.
