Inspect the gear surface and bearing surface for wear and damage, then measure the countershaft at points A, B, and C. If any part of the countershaft is less than the service limit, replace it with a new one.

A Ball Bearing Surface (Transmission Housing   Side):
	26.020−26.033 mm (1.0244−1.0249 in.)
B Distance Collar Surface:
	38.987−39.000 mm (1.5349−1.5354 in.)
C Needle Bearing Surface (Clutch Housing Side):
	34.000−34.015 mm (1.3386−1.3392 in.)

Service Limit:
A:	25.97 mm (1.022 in.)
B:	38.94 mm (1.533 in.)
C:	33.95 mm (1.337 in.)

Inspect the runout by supporting both ends of the countershaft. Rotate the countershaft two complete revolutions when measuring the runout. If the runout exceeds the service limit, replace the countershaft with a new one.

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