4. Support the bottom of the countershaft with one hand, then press the countershaft out of the press-fitted 

bearing (E) and the press-fitted reverse selector hub. The countershaft will drop down after pressing it out 
of the press-fitted reverse selector hub. Some reverse selector hubs are not press-fitted, and the 
countershaft will drop down after pressing it out of the press-fitted bearing.  

5. Remove the remaining parts from the countershaft.  

6. Inspect the bearing for galling and rough movement.  

7. Check the shaft bearing surfaces for scoring and excessive wear, and check the shaft splines for excessive 

wear and damage.  

8. Check the idler gear axial clearance and 4th gear axial clearance (see COUNTERSHAFT IDLER 

GEAR AND 4TH GEAR AXIAL CLEARANCE INSPECTION ).  

COUNTERSHAFT IDLER GEAR AND 4TH GEAR AXIAL CLEARANCE INSPECTION 

1. Install 2nd gear (A), the thrust needle bearing (B), needle bearing (C), idler gear (D), thrust needle 

bearing (E), the original thickness 56 mm washer (F), 1st gear (G), 4th gear (H), the original thickness 
50.2 mm washer (I), 39 mm cotters (J), cotter retainer (K), and snap ring (L) on the countershaft (M).
