B: 26.980-26.993 mm (1.0622-1.0627 in)
C: 33.984-34.000 mm (1.3380-1.3386 in)
D: 25.977-25.990 mm (1.0227-1.0232 in)
Service Limit: A: 21.93 mm (0.8634 in)
B: 26.93 mm (1.0602 in)
C: 33.93 mm (1.3358 in)
D: 25.92 mm (1.0205 in)

If any part of the mainshaft is less then the service limit, replace it with a new one.

2. Inspect for runout.

Standard:   0.02 mm (0.001 in) min. Service Limit: 0.05 mm (0.002 in)
