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 center 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 bal-
ancer shaft and the oil pump module becomes off, result-
ing 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.

ULE 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 cm
3
[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. 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.

6. Tighten the balancer shaft and oil pump module bolts to the
specified torque 20 N
⋅m (15 ft-lb) in the order of number
shown in the figure.
7. Tighten the balancer shaft and oil pump module bolts again
to the specified torque 44 N
⋅m (33 ft-lb) in the order of
number shown in the figure.
8. Loosen the balancer shaft and oil pump module bolts fully in
the reverse sequence to that shown.
9. Tighten the balancer shaft and oil pump module bolts to the
specified torque 20 N
⋅m (15 ft-lb) in the order of number
shown in the figure.
10.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.
11.Tighten the mounting bolt of the balancer timing chain guide
lower with the standard torque.
Tightening torque: 10
± 2 N⋅m (89 ± 17 in-lb)
12.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]).
