Gearshift fork to groove clearance Note

the clearance for each gearshift fork plays an important role in the smoothness and positiveness of the shifting action.

Using the thickness gauge, check the gearshift fork clearance in the groove of its gear.

If the clearance checked is noted to exceed the limit specified, replace the fork or its gear, or both.
