SYSTEMS OPERATION
The transmission control (gearshift mechanism)
consists of three shift rails, three shift forks,
spring-loaded detent balls and a shift lever. This
mechanism is designed so~that it is only possible
to engage one gear reduction at a time.
The interlock mechanism ~consjsts of a pin and
steel bails which fit into notches on the shift rails.
If 1st shift rail 7is moved for making a shift (the
shift lever is moved to forward 1st-speed posi
tion), for example, 2nd shift rail 8 and 3rd shift
rail 9 are locked by the steel balls. This holds the
transmission
gears
so that they will not slide out
of position.
