MT-64 MANUAL TRANSMISSION — Component Parts (Output Shaft Assembly) (c) Using a dial indicator, check the shaft runout. Maximum runout: 0.06 mm (0.0024 in.) 4. INSPECT SYNCHRONIZER RINGS (a) Turn the ring and push it in to check the braking action. (b) Measure the clearance between the synchronizer ring back and the gear spline end. Standard clearance: 0.8 — 1.6 mm (0.031 — 0.063 in.) Minimum clearance: 0.6 mm (0.024 in.) If the clearance is less than the limit, replace the synchronizer ring. 5. MEASURE CLEARANCE OF SHIFT FORKS AND HUB SLEEVES Using a feeler gauge, measure the clearance between the hub sleeve and shift fork. Maximum clearance: 1.0 mm (0.039 in.) If the clearance exceeds the limit, replace the shift fork or hub sleeve.
