Measure the clearance between the 2nd gear (A) and 3rd gear (B) with a feeler gauge (C). If the clearance is more than the service limit, go to step 4. Standard: 0.04 - 0.12 mm (0.002 - 0.005 in.) Service Limit: 0.24 mm (0.009 in.) Measure the thickness of the spacer collar. If the thickness is less than the service limit, replace the spacer collar with a new one. If the thickness is within the service limit, go to step 5. Standard: 27.53 - 27.56 mm (1.084 - 1.085 in.) Service Limit: 27.51 mm (1.083 in.)

Measure the thickness of 2nd gear. If the thickness of 2nd gear is less than the service limit, replace 2nd gear with a new one. If the thickness of 2nd gear is within the service limit, replace the 1st/2nd synchro hub with a new one. Standard: 27.41 – 27.46 mm (1.079 – 1.081 in.) Service Limit: 27.36 mm (1.077 in.)
