Synchronizer Ring Clearance Inspection
Synchronizer Ring Clearance InspectionSynchronizer component (1st gear)
1. Measure the clearance of synchronizer component outer, middle and inner synchronizer rings.
^ If clearances A and B exceed the maximum, replace as a set.
1) Measure clearance A in two places or more and on opposite sides using a dial gauge, and calculate the average value.
Clearance A
Standard:
0.60 - 0.80 mm (0.0236 - 0.0315 in)
Maximum:
0.20 mm (0.0079 in) or less
2) Measure clearance B in two places or more and on opposite sides using a feeler gauge, and calculate the average value.
Clearance B
Standard:
0.60 - 1.10 mm (0.0236 - 0.0433 in)
Maximum:
0.20 mm (0.0079 in) or less
Synchronizer component (2nd gear)
1. Inspect clearance of the synchronizer component outer, middle, and inner synchronizer rings.
^ If the clearance A, B and C exceed the maximum, replace as a set.
1) Measure clearance A in two places or more and on opposite sides using a feeler gauge while the synchronizer ring is manually press fit to the taper surface of the clutch gear, and calculate the average value.
Clearance A
Standard:
0.60 - 1.20 mm (0.0236 - 0.0472 in)
Maximum:
0.30 mm (0.0118 in) or less
2) Measure clearance B in two places or more and on opposite sides with a feeler gauge, and calculate the average value.
Clearance B
Standard:
0.60 - 1.10 mm (0.0236 - 0.0433 in)
Maximum:
0.20 mm (0.0079 in) or less
3) Measure clearance C in two places or more and on opposite sides with a feeler gauge while the synchronizer ring is manually press fit to the taper surface of the clutch gear, and calculate the average value.
Clearance C
Standard:
0.70 - 1.10 mm (0.0276 - 0.0433 in)
Maximum:
0.30 mm (0.0118 in) or less
