      0.20 to 0.38 mm (0.00787 to 0.0150 in.)

      Maximum Clearance
      0.38 mm (0.0150 in.)

      If the clearance exceeds the maximum, replace the No. 1 transmission clutch hub, 1st gear bush or 1st gear.

      Maximum Clearance
      0.33 mm (0.0130 in.)

      If the clearance exceeds the maximum, replace the inner 2nd gear bearing race, No. 1 transmission clutch hub, 2nd gear or 3rd driven gear.
