1. Turn the crankshaft clockwise to align the timing 

mark of the balancer shaft sprocket with the timing 
mark of the balancer shaft and oil pump module, 
and set the cylinder No. 1 or No. 4 to the top dead 
centre of compression.

2. Put paint marks on the balancer shaft sprocket 

timing mark and balancer timing chain.

CAUTION

Securely install the plunger of the timing chain 
tensioner. Otherwise, it may pop out.

3. Press the balancer timing chain against the timing 

chain tensioner, compress the plunger of the 
timing chain tensioner and insert L-shaped hard 
wire (piano wire of 

φ1.5 mm) or L-shaped 

hexagon wrench (1.5 mm) to the plunger fixing 
hole of the timing chain tensioner from under the 
timing chain case, and fix the plunger of the timing 
chain tensioner.

4. Use a wrench to remove the mounting bolt at the 

lower side of the balancer timing chain guide 
shown in the figure so that the balancer timing 
chain guide is unrestricted.

5. Support the balancer shaft and oil pump module 

with a hand, and remove the balancer shaft and 
oil pump module mounting bolt.

6. Remove the balancer shaft and oil pump module 

from the rudder frame with the balancer timing 
chain attached, and move it to the centre of the 
engine.

7. Remove the balancer timing chain from the 

balancer shaft and oil pump module, and remove 
the balancer shaft and oil pump module.

CAUTION

When the tooth jump of the balancer timing chain 
from the crankshaft sprocket occurs, the timing 
between the balancer shaft and the oil pump 
module becomes off, resulting in the abnormal 
engine vibration. Be sure that the tooth jump will 
not occur.

8. After the balancer shaft and oil pump module is 

removed, using a cable band, tie the balancer 
timing chain at the protrusion of the rudder frame 
to prevent the tooth jump of balancer timing chain 
from the crankshaft sprocket.

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 mL) 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. Remove the cable band installed to prevent the 

tooth jump of the balancer timing chain from the 
crankshaft sprocket from the balancer timing 
chain.

3. 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 marking of the balancer shaft sprocket 
(the timing mark of the new balancer shaft and oil 
pump module) with that of the balancer timing 
chain.

4. With the paint marking 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.

5. Apply an adequate and minimum amount of 

engine oil to the threads and bearing surfaces of 
the balancer shaft and oil pump module bolts.

10.After tightening to the specified torque, tighten the 

balancer shaft and oil pump module bolts to 135 
degrees, using special tool angle gauge 
(MB991614), in the order of number shown in the 
figure.

11.Tighten the mounting bolt of the balancer timing 

chain lower with the standard torque.

12.Remove the plunger of the timing chain tensioner 

using the L-shaped hard wire (

φ1.5 mm piano 

wire, etc.) or L-shaped hexagon wrench (1.5 mm).
