REPAIR INSTRUCTIONS
7.Using a suitable press arrangement, align fourth (eighth) gear slot with countershaft key and press gear onto shaft until gear hub is approximately 6.4 to 12.7 mm (1/4 to 1/2 inch) from contacting the hub of the second (sixth) speed gear.
The fourth/eighth speed gear must only be partially installed by itself (as shown) to avoid cracking in the circle of low-inertia holes.
8.Align the hub of the main drive gear with the key of the countershaft and allow the protruding hub of the gear to face the rear of the shaft.
9.Press the main drive gear onto the shaft until seated against the fourth (eighth) speed gear. Continue pressing on the main drive gear to install both the fourth (eighth) and the main drive gears on at the same time. This action places all of the press pressure on the hub of the main drive gear and none on the web of the fourth (eighth) speed gear. Check that the main drive gear is flush with the end of the countershaft after installation.
10.At this time, install a new bearing cone onto the rear of the No. 2 countershaft only. Using a suitable driver, apply force only to the inner race of the bearing cone. Install the bearing until seated against the surface of the reverse speed gear (part of shaft). Delay installation of the No.1 and No. 3 countershaft rear bearing cones until after countershaft installation into the case.
