• When the bearings fail to turn smoothly or emit noise in rotation after gear oil lubrication.
2. Drive gear
If the drive gear tooth surface and shaft are excessively broken or damaged, replace the drive gear.
3. Measure the clearance between snap ring and inner race of ball bearing with a thickness gauge.
