1. Measure the clearance between each gear (A) and its synchro ring (B) all around the gear. Hold the synchro ring against the gear evenly while measuring the clearance. If the clearance is less than the service limit, replace the synchro ring and gear.
   Synchro Ring-to-Gear Clearance

   Standard: |
   3rd/4th gear: | 0.70−1.49 mm (0.028−0.059 in.)
   5th/6th gear: | 0.73−1.44 mm (0.029−0.057 in.)
   Service Limit: | 0.4 mm (0.016 in.)

   Triple Cone Synchro-to-Gear Clearance

   Standard:
   (1): | Outer Synchro Ring (B) to Synchro Cone (C)
   | 1st gear: | 0.70−1.19 mm (0.028−0.047 in.)
   | 2nd gear: | 0.70−1.19 mm (0.028−0.047 in.)
   (2): | Synchro Cone (C) to Gear (A)
   | 1st/2nd gear: | 0.45−1.14 mm (0.018−0.045 in.)
   (3): | Outer Synchro Ring (B) to Gear (A)
   | 1st/2nd gear: | 1.12−1.68 mm (0.044−0.066 in.)
   Service Limit:
   (1): | 0.3 mm (0.012 in.)
   (2): | 0.3 mm (0.012 in.)
   (3): | 0.6 mm (0.024 in.)
