Do not turn the balancer shaft during clearance mea-
Remove the lower crankcase half and measure the plas-
tigage width [A] to determine the bearing insert/journal [B]
Balancer Shaft Bearing Insert/Journal Clearance
0.011 ∼ 0.033 mm (0.0004 ∼ 0.0013 in.)
Service Limit: 0.06 mm (0.002 in.)
If the clearance is within the standard, no bearing insert
replacement is required.
If the clearance is between 0.034 mm (0.00134 in.) and
the service limit (0.08 mm (0.003 in.)), replace the bearing
inserts [A] with inserts painted blue [B] Check insert/jour-
nal clearance with a plastigage. The clearance may ex-
ceed the standard slightly, but it must not be less than the
minimum in order to avoid bearing seizure.
If the clearance exceeds the service limit, measure the
diameter of the balancer shaft journal.
Balancer Shaft Journal Diameter
27.987 ∼ 28.000 mm (1.1019 ∼ 1.1024 in.)
Service Limit: 27.96 mm (1.1008 in.)
If either journal has worn past the service limit, replace
the balancer shaft with a new one.
If the measured journal diameters are not less than the
service limit, but do not coincide with the original diameter
markings on the balancer shaft, write new marks on it.
