1. Install the countershaft front bearing races by heating them with a bearing race heater, and pressing them on with an arbor press or appropriate race driver.

2. Install the auxiliary countershaft front bearing races on the front countershafts by heating them with a bearing race heater, and pressing them on with an arbor press or appropriate race driver.

3. For timing purposes, use a highly visible toolmakers die to mark the 4th gear teeth on each front countershaft. Locate and paint the two adjacent teeth that line up with the timing mark on each shaft (usually a ’0’).

4. Slide each front countershaft into the auxiliary countershafts while lining up the marked teeth on the countershaft gears with the marked teeth on the mainshaft gear as shown.
