A/T Mainshaft 5th Gear Axial Clearance Inspection
  1. Install the thrust needle bearing (A), 5th gear (B), the needle bearing (C), the thrust needle bearing (D), the 41 x 68 mm thrust washer (E), the 4th/5th clutch (F), the 4th gear collar (G), and the transmission housing bearing (H) on the mainshaft (I). Do not install the O-rings during inspection.
  1. Install the idler gear (J) on the mainshaft with a press, then install the conical spring washer (K) and the locknut (L).
  1. Tighten the locknut to 29 N·m (3.0 kgf·m, 22 lbf·ft).
  1. Set the dial indicator (A) on 5th gear (B).
  1. Lift 5th gear (A) up while holding the mainshaft, and use the dial indicator (B) to read the 5th gear axial clearance.
  1. Measure the 5th gear axial clearance in at least three places while moving 5th gear. Use the average as the actual clearance.
    Standard:
    0.04−0.10 mm (0.002−0.004 in.)

  1. If the clearance is out of standard, remove the 41 x 68 mm thrust washer and measure its thickness (A).
  1. Select and install a new thrust washer, then recheck.
