This section will allow you to properly identify all the components of the transmission and selector mechanism, and understand how each one of them functions as an essential part of the whole unit.
How The Transmission Works
There are five gears on the mainshaft, (Fig. 23) one of which can be
slid back and forth to engage the gear on its left. This engagement is
done by small pegs on the sides of the gears. These pegs are called engaging
dogs. The mainshaft also utilizes a separate gear engaging device called
a sliding dog.
