A) By rotating and simultaneously pressing the synchronizer ring, check its frictional properties.
b) Measure the clearance between the synchronizer ring and the gear.
Nominal clearance - 1.0 - 2.0 mm
Minimum clearance - 0.8 mm
V) If the clearance is out of specification, replace the synchronizer ring.
2. Replacing the input shaft bearing (if necessary).
A) Remove the snap ring.
b) Using a press, remove the bearing.
V) Using a press and drift, install the new bearing.
G) Select a circlip with minimum axial clearance and install it on the shaft.
