Balancer Shaft Alignment
1. Support the balancer shaft with V blocks on the surface plate
and set a dial indicator with its tip on the intermediate journal at
high angle.
2. Rotate the balancer shaft on the V block and get the
misalignment (half of the measurement value).
3. If the misalignment exceeds the allowable limit, replace the
balancer shaft.

Oil Clearance of Balancer Shaft Journal
1. Measure the balancer shaft journal O.D. with an outside
micrometer.
2. Measure the cylinder block bore I.D. (A), (B) for balancer shaft
with an inside micrometer.
3. If the clearance exceeds the allowable limit, replace the
balancer shaft bearing. If it still exceeds the allowable limit,
replace also the balancer shaft.
