Synchronizer Assembly Inspection
1. Inspecting wear of cone area.

After matching synchronizer ring to gear, measure
as shown in figure. Replace if it is below limit.
Unit : mm (in.)
Clearance Between Standard Limit Clearance Between
Gear and Ring
1.0 (0.039)0.5 (0.020)

2. Inspecting cone contact condition.

When synchronizer mechanism is abnormal in op-
eration, connection between ring inner surface and
gear cone area is considered to be partially defec-
tive in spite of correct clearance between gear and
ring. Therefore, cone area and ring inner surface
shall be inspected. In this case, ring inner surface
shall be glossy. Black area is abnormal and if in-
spection is difficult, check after applying red lead.
Cone area can be worn in wave form.
