TRANSMISSION CASE PREPARATION
Surgically clean the left side of the transmission case in preparation for installing the new
GrudgeBox main drive gear and gearset. This surgical cleansing includes the main drive gear
and countershaft bearing boss areas, the three inner primary mount bosses, and the shifter
pawl boss. See figure 7.
The bearing boss areas must be clean to ensure that no dirt or debris scores the bearing bores
during the removal of old bearings and installation of new ones. The three inner primary mount
bosses need to be clean so that the tool plate registers flat on the left side transmission case.

TAPERED ROLLER BEARING ADAPTER AND MAIN DRIVE GEAR.
WATCHING THE VIDEO AHEAD OF TIME WILL GIVE YOU THE TIPS,
TRICKS, AND KNOWLEDGE TO ENSURE A PROPER INSTALLATION.
CAUTIONARY NOTE
There are special tools available from other manufacturers that remove and install the
countershaft cup bearing, but they all have one fundamental error
– they push on the inside of
the cup (from right to left in the motorcycle) for removal and installation. THIS IS WRONG! Cup
bearings require that the installation force be applied to the outside of the cup (from left to
right). BAKER TOOLE-07 (sold separately) applies removal and installation forces in the
proper direction.
