1.After wiping off the dirt
on the crankshaft gear as shown in the figure using a rag,
degrease
the areas.
| note |
Degrease them to prevent drop
in the friction coefficient of the pressed area,
which is
caused by oil adhesion.
|
2.
Check
that the timing marks on the gears are aligned. Then install
the components.
|
|
1.Apply the appropriate and
minimum amount of engine oil to the thrust plate, as shown
in
the illustration.
2.Install all of these so that
the thrust plate face where the engine oil is applied
can face toward the balancer shaft drive housing and gear
assembly.
|
|
|
The dowel pin should protrude 5.75
±
0.15 mm from the end of the balancer unit.
|
|
1.Install the washer to the
balancer unit bolt so that the washer chamfered side faces
as
shown.
2.Apply the minimum amount of engine oil to
the balancer unit bolt threads and the seating
surface.
3.
| caution |
The crankshaft should always
be turned in a clockwise direction.
|
Set the No. 1 cylinder at top dead centre.
|
|
4.Install the lower
crankcase so that the timing mark on the balancer unit
should face as
shown.
5.Tighten the balancer unit bolt to the
specified torque in the order shown in the
figure.
Tightening torque: 20 ±
1 N·m
|
|
6.
| caution |
- When the tightening angle is smaller
than
the specified tightening angle, the
appropriate tightening capacity cannot
be secured.
- When the tightening angle is larger than
the specified tightening angle, remove
the bolt to start from the beginning
again according to the
procedure.
|
Use special tool angle gauge (MB991614) to tighten
them an additional 60°.
7.Loosen the
balancer unit bolt fully.
8.Tighten the balancer
unit bolt to the specified torque again in the order shown
in
the figure.
Tightening torque: 20 ±
1 N·m
9.Use special tool angle gauge
(MB991614) to tighten them an additional 60°.
