Caution
•  If the counter lever shaft has been replaced or the locknut is loose, assemble the counter lever shaft with the chamfer side of the shaft pointed straight upward.
•  Apply sealant to the threads of the locknut.
•  If there is an abnormality in the 3rd/4th shift stroke after assembling, loosen the locknut and readjust.
Locknut tightening torque:
37.3—51.9 N·m {3.81—5.29 kgf·m, 27.6—38.2 ft·lbf}


Reverse Idler Gear Component Assembly Note

1.  Using the SSTs, install the friction damper to the reverse idler gear.
