Baulk Ring Clearance

WARNING: This page is about a different car, the 2004 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

Double cone synchronizer (1st-2nd)

Check the clearance of outer baulk ring, synchronizer cone, and inner baulk ring of 1st-2nd 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.

Using a dial gauge and Tool, measure clearance "A" at two or more points diagonally opposite, and calculate mean value.
Clearance "A"

Standard: 0.6 - 0.8 mm (0.024 - 0.031 in)

Limit value: 0.2 mm (0.008 in) or less

Using a feeler gauge, measure clearance "B" at two or more points diagonally opposite, and calculate mean value as shown.
Clearance "B"

Standard: 0.6 - 1.1 mm (0.024 - 0.043 in)

Limit value: 0.2 mm (0.008 in) or less
