Shift rod
STRUCTURE

• The shift lever stroke has been set shorter to provide optimal shift feel.

• To realize assured shift feel, the shift link mechanism has been integrated.

• Due to the use of metal bushings for the sliding parts of the shift rod, sliding resistance during shifting is greatly

reduced, thus improving shift quality.

TRIPLE SYNCHRONIZER MECHANISM STRUCTURE [P66M-D]

E5U051100000N05

Features

• A triple cone synchronizer mechanism is used for the 1st, 2nd, 3rd and 4th gears.

• The triple cone synchronizer mechanism is a compact device capable of heavy duty meshing.

• The synchro mechanism reduces meshing time and improves operation.

• The triple cone synchro mechanism includes a synchronizer ring, a double cone, and an inner cone.

TRIPLE SYNCHRONIZER MECHANISM OPERATION [P66M-D]

E5U051100000N06

1. When the hub sleeve moves to the left (in the

direction of the arrow), the synchronizer key
presses against the synchronizer ring.

2. As the hub sleeve continues moving to the left,

the key causes friction between the synchronizer
ring, double cone, and inner cone. The
synchronizer ring turns only the distance that the
key groove gap allows, aligning the teeth of the
hub sleeve and the synchronizer ring. As the hub
sleeve continues moving, the friction between the
cones becomes greater, and the difference
between the rotational speeds of the synchronizer
ring, inner cone, and double cone (unified with the
gear) gradually disappears.

3. The hub sleeve then moves up onto the

synchronizer key and engages the synchronizer
ring.

4. The hub sleeve then engages the synchro teeth

of the gear to complete shifting.

SHIFT INTERLOCK MECHANISM FUNCTION [P66M-D]

E5U051100000N07

• This provides reliable double-engagement prevention.

End Of Sie

SHIFT INTERLOCK MECHANISM OPERATION [P66M-D]

E5U051100000N08

Structure

• During shifting, the shift rods, except for the one in operation, are locked in the neutral position by the interlock

pins.

Operation
Neutral

• Each interlock pin is in the groove of each shift

rod because no shift rod is operating.

1st/2nd shifting

• Movement of the 1st/2nd shift rod forces interlock

pins A and C out of the 1st/2nd shift rod grooves,
and the reverse shift rod and 3rd/4th shift rod are
locked. In addition, interlock pin C forces interlock
pin E out via interlock pin D, and the 5th/6th shift
rod is locked.

3rd/4th shifting

• When the 3rd/4th shift rod operates, the other

three shift rods are locked in the same way as the
1st/2nd shifting.
