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).
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.

(C) Piston and Connecting Rod
Piston Pin Bore I.D.
1. Measure the piston pin bore I.D. in both the horizontal and
vertical directions with a cylinder gauge.
2. If the measurement exceeds the allowable limit, replace the
piston.
