BAULK RING CLEARANCE 

Triple-cone synchronizer (1st and 2nd)

• Check the clearance between outer baulk ring, synchronizer cone, and inner baulk ring as follows.
  CAUTION: The clearances (A), (B), and (C) are controlled with outer baulk ring, synchronizer cone, and inner baulk ring as a set. Replace them as a set if the clearances are outside the limit value.

1. Measure the clearance (A) at 2 points or more diagonally opposite using a feeler gauge when pressing baulk ring toward clutch gear taper cone. And then calculate mean value.

   Clearance (A) 

   Standard value :  Refer to "BAULK RING CLEARANCE ".

   Limit value :  Refer to "BAULK RING CLEARANCE ".

2. Measure the clearance (B) at 2 points or more diagonally opposite using a feeler gauge. And then calculate mean value.

   Clearance (B) 

   Standard value :  Refer to "BAULK RING CLEARANCE ".

   Limit value :  Refer to "BAULK RING CLEARANCE ".

3. Measure the clearance (C) at 2 points or more diagonally opposite using a feeler gauge when pressing baulk ring toward clutch gear taper cone. And then calculate mean value.

   Clearance (C) 

   Standard value :  Refer to "BAULK RING CLEARANCE ".

   Limit value :  Refer to "BAULK RING CLEARANCE ".
