REMOVAL SERVICE POINT

TIMING CHAIN TENSIONER REMOVAL

CAUTION

Securely install the plunger of the timing chain tensioner.

Otherwise, it may pop out.

1. Press the balancer timing chain against the timing chain tensioner, compress the plunger of the timing chain tensioner and insert hard wire (piano wire, etc.) or L-shaped hexagon wrench (1.5 mm [0.05 inch] ) to fix the plunger of the timing chain tensioner.

2. Remove the timing chain tensioner.

INSTALLATION SERVICE POINTS

CRANKSHAFT SPROCKET/BALANCER TIMING CHAIN/BALANCER SHAFT AND OIL PUMP MODULE INSTALLATION

1. When installing the new balancer shaft and oil pump module, apply 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 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.

2. With the link marks (orange or blue) of balancer timing chain aligned with the timing marks of balancer sprocket and crankshaft sprocket, install the balancer shaft and oil pump module together with the balancer timing chain and crankshaft sprocket as one unit to the cylinder block. At this time, securely bring the balancer shaft and oil pump module into contact with the rudder frame mounting area.

3. Apply an adequate and minimum amount of engine oil to the threads and bearing surfaces of the balancer shaft and oil pump module bolts.

4. Tighten the balancer shaft and oil pump module bolts to the specified torque of 20 N*m (15 ft-lb) in the order of number shown in the figure.

5. Retighten the balancer shaft and oil pump module bolts to the specified torque of 44 N*m (33 ft-lb) in the order of number shown in the figure.

6. Loosen each balancer shaft and oil pump module bolt fully in the reverse sequence to that shown.

7. Tighten the balancer shaft and oil pump module bolts to the specified torque of 20 N*m (15 ft-lb) in the order of number shown in the figure.

8. After tightening to the specified torque, tighten the balancer shaft and oil pump module bolts to 135 degrees, using special tool MB991614, in the order of number shown in the figure.

TIMING CHAIN TENSIONER INSTALLATION

1. Install the timing chain tensioner to the cylinder block.

2. Remove the hard wire or L-shaped hexagon wrench fixing the plunger of the timing chain tensioner to apply tension to the balancer timing chain.
