Part IV Disassembly and Maintenance
68
Alignment between crankshaft and balance shaft
The main damage of timing gear is the wear of gear tooth, tooth face peeling or roughness,
gear deflection, gear tooth breakage, etc. Due to the wear of gear teeth, the greater the meshing
clearance is, the greater the noise will be.
If gear face of timing tooth is bruised or damaged or rupture angle, it shall be replaced
with a new one for any case.
When replacing new parts, it is better to replace the whole part to ensure that there is a more
consistent meshing surface.
