>>A<< Balancer Shaft And Oil Pump Module Installation

WARNING: This page is about a different variant/trim than selected.

When installing the new balancer shaft and oil pump module, apply engine oil to the oil pump in the balancer shaft and oil pump module and the balancer shaft bearing as follows.
1. Clean the inside of the removed engine oil pan, and put the balancer shaft and oil pump module into the engine oil pan with its oil inlet port facing up.
2. Pour new engine oil until two-thirds of the balancer shaft and oil pump module is soaked.
3. Fill the new engine oil [approximately 50 cm³ (3.05 cu.in.)] into the balancer shaft and oil pump module from the oil inlet port.

4. Turn the balancer shaft sprocket of the balancer shaft and oil pump module clockwise four rotations or more to apply the engine oil to the entire area of the oil pump and the balancer shaft bearing.
Remove the cable band installed to prevent the tooth jump of the balancer timing chain from the crankshaft sprocket from the balancer timing chain.

Regarding the prevention of the tooth jump of the balancer timing chain, install the balancer shaft sprocket to the balancer timing chain with aligning the paint mark of the balancer shaft sprocket (the timing mark of the new balancer shaft and oil pump module) with that of the balancer timing chain.
With the paint mark of the balancer timing chain aligned with that of the balancer sprocket (the timing mark of the new balancer shaft and oil pump module), install the balancer shaft and oil pump module to the rudder frame. Securely bring the balancer shaft and oil pump module into contact with the rudder frame mounting area.

Loosen each balancer shaft and oil pump module mounting bolts fully in the reverse sequence to that shown.
Tighten the balancer shaft and oil pump module mounting bolts again to the specified torque in the order of number shown in the illustration.
Tightening torque: 20 N.m (15 ft-lb)
After tightening to the specified torque, tighten the balancer shaft and oil pump module mounting bolts to 135 degrees angle, using special tool MB991614, in the order of number shown in the illustration.
Tighten the mounting bolt of the lower side of the balancer timing chain guide with the standard torque.
Tightening torque: 10 ± 2 N.m (89 ± 17 in-lb)
Remove the plunger of the timing chain tensioner using the L-shaped hard wire (piano wire, etc.) or L-shaped hexagon wrench [1.5 mm (0.05 inch).]
