BALANCERS
The balancer is fitted to control 'pulsing' within the
engine. Without any form of balancer, the engine would
'pulse' each time the crankshaft rotated. This 'pulsing'
would be felt as a vibration which would amplify as the
engine speed was increased.
The balancer has the effect of a pair of counterbalance
weights which create an equal amount of energy in the
opposite direction, and at the same time as that
produced by the crankshaft, pistons and connecting
rods. Because the opposing pulses occur at the same
point of crankshaft rotation, and are of an equal
magnitude, a state of equilibrium or balance is reached.
Alignment Inspection
If the balancer is not correctly orientated in relation to the
crankshaft, severe engine vibration will occur.
In
circumstances where severe engine vibration is
experienced, the relationship of the balancer to the
crankshaft must be checked.
1.
Disconnect the battery, negative (black) lead first.
2. Drain the engine oil into a clean container.
3.
Remove the clutch cover as described in the clutch
section.
4.
Lever out the plug shown in the illustration below
from the right hand side of the crankcase. Take care
not to mark or damage the case during removal.
1. Crankcase Plug
NOTE:
•
The plug will be damaged during removal and
must be discarded.
5.
Turn the engine over until the 'Ti' mark on the
crankshaft rotor aligns with the centre of the
crankshaft position sensor.
1. 'Ti' Mark
2. Crankshaft Position Sensor
6. Examine the marking on the end of the balancer
shaft and check that the markings align with the
corresponding pointers on the outside of the
crankcase. If the markings align as shown below,
the balancer is correctly aligned.
1. Balancer Shaft Markings
2. Crankcase Pointers
CAUTION: If the markings do not align as
shown, the balancer must be removed,
checked and refitted in the correct alignment
position. Continued engine operation with an
incorrectly aligned balancer will cause premature
engine wear and permanent engine damage.
7.
Fit a new plug to the right hand side of the crankcase
as described in `balancer plug fitting'.
8.
Refit the clutch cover as described in the clutch
section.
