3. Using feeler gauge put and press baulk ring on gear taper cone,
and then measure “clearance C” at more then 2 diagonal points,
and calculate the average.

Reverse synchronizer
Push baulk ring on the cone and measure baulk ring back sur-
face clearance at two locations or more on opposite sides, find
the average value, and replace if it is outside the limit value.
Bearing
If the bearing does not rotate smoothly or the contact surface on ball
or race is damaged or peeled, replace with new ones.Clearance C
Standard value
(1st): 0.80 - 1.2 mm (0.031 - 0.047 in)
Standard value
(2nd, 3rd): 0.75 - 1.25 mm (0.030 - 0.049 in)
Limit value : 0.3 mm (0.012 in) or less
