Baulk Ring Clearance
Double Cone Synchronizer (1st)
Check the clearance of outer baulk ring, synchronizer cone, and
inner baulk ring of 1st double cone synchronizer, using the following
steps.
NOTE:
The mean value is the middle value of a set of measurements
between the highest and lowest values. It is calculated by adding the
highest and lowest measured value and dividing their sum by two:
[(high value) + (low value)] / 2 = mean value.
CAUTION:
Outer baulk ring, synchronizer cone, and inner baulk ring act as
a set to control the clearances “A” and “B”. If the measurement
exceeds the service limit value, replace all of them as a set.
1. Using a dial gauge and Tool, measure clearance “A” at two or
more points diagonally opposite, and calculate mean value.
2. Using a feeler gauge, measure clearance “B” at two or more
points diagonally opposite, and calculate mean value as shown.
Triple Cone Synchronizer (2nd)
Check the clearance of the outer baulk ring, synchronizer cone, and
inner baulk ring of the 2nd triple cone synchronizers, using the fol-
lowing procedure.
CAUTION:
The outer baulk ring, synchronizer cone, and inner baulk ring
operate as a set to control the clearances “A”, “B”, and “C”. If
the measured clearances exceed the service limit value, replace
the components as a set.
NOTE:
To calculate the mean value of two or more measured values, add
the highest and lowest measured values and divide by two.
