Disassembly
DISASSEMBLY PROCEDURE 1. INSPECT 3RD GEAR THRUST CLEARANCE (a) Using a dial indicator, measure the 3rd gear thrust clearance. Standard clearance: 0.200 to 0.490 mm (0.0079 to 0.0192 in.) If the clearance is outside the specification, replace the 3rd gear, thrust washer, c ...

Inspection
INSPECTION PROCEDURE 1. INSPECT REAR AXLE SHAFT (a) Using a dial indicator, measure the runout of the shaft and flange. Maximum runout: Shaft runout: 1.5 mm (0.0591 in.) Flange runout: 0.05 mm (0.0020 in.) If the rear axle shaft or flange is damaged or worn, or the runout is greater than ...
