Measure the clearance between 1st gear (A) and the countershaft (B) with a feeler gauge (C). If the clearance is more than the service limit, go to step 2. Standard: 0.03 - 0.12 mm (0.001 - 0.005 in.) Service Limit: 0.22 mm (0.009 in.) Measure the thickness of 1st gear. If the thickness of 1st gear is less than the service limit, replace 1st gear with a new one. If the thickness of 1st gear is within the service limit, replace the 1st/2nd synchro hub with a new one. Standard: 26.91 – 26.94 mm (1.059 – 1.061 in.) Service Limit: 26.86 mm (1.057 in.)
