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
Remove the remaining parts from the countershaft
Inspect the bearing for galling and rough movement
Check the shaft bearing surfaces for scoring and excessive wear, and check the shaft splines for excessive wear and damage
NOTE: If the countershaft is worn or damaged, replace the countershaft with the same letter (A, B, or C) for identification as the identifying letter on the final driven gear
Check the idler gear axial clearance and the 4th gear axial clearance (see COUNTERSHAFT IDLER GEAR AND 4TH GEAR AXIAL CLEARANCE INSPECTION )
