is moved forward to engage the
rear of the main drive gear. The
ring gear remains in the neutral
position. Thus the main drive
gear is in contact with the main-
shaft through the clutch sleeve.
3rd or Direct Gear - Power Flow
- Torque imparted to the main
drive gear is applied directly to
the mainshaft through the clutch
sleeve.

Action - The shifter fork slides
the ring gear rearward to engage
the rear gear on the reverse idler
gear. The forward gear of the

Torque imparted to the main
drive gear is applied to the
countergear. The middle gear on
the counter, being in mesh with
the idler gear, transmits the
torque to the idler gear. The idler

the ring gear and t r a n s m i t s
torque to it and the clutch sleeve
to which the ring gear is splined.
The clutch sleeve then turns the
mainshaft.
