BAULK RING CLEARANCE 

• Single-cone synchronizer (4th, 5th, and 6th) 

  Push baulk ring on the cone and measure the clearance between baulk ring and cone. If measurement is below limit, replace it with a new one.

  Clearance 

  Standard value :  Refer to "BAULK RING CLEARANCE ".

  Limit value :  Refer to "BAULK RING CLEARANCE ".

• Double-cone synchronizer (3rd) 

  Check the clearance between outer baulk ring, synchronizer cone, and inner baulk ring as follows.

  CAUTION: The clearances (A) and (B) 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 dial indicator. And then calculate mean value.

   Tool number : ST30031000 (J-22912-01) 

   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 ".
