Double-cone synchronizer is adopted for 1st and 2nd gears to
reduce operating force of the shift lever.

(2): 2nd main gear
(3): Synchronizer cone
(4): Inner baulk ring
(5): 1st main gear
(6): 1st-2nd coupling sleeve
REVERSE GEAR NOISE PREVENTION FUNCTION (SYNCHRONIZING METHOD)
Description
Soon after the clutch is disengaged, the input shaft is still rotating due to inertia. This may cause a gear noise
when the gear is shifted to reverse position. The reve rse gear noise prevention function stops the rotation of
the input shaft and enables smooth gear shifting when the reverse gear is selected.
Operation Principle
1. When the gear is shifted to reverse position, 5th-reverse cou-
pling sleeve (1) slides in the reverse direction( )
5: 5th input gear
2. Synchronizer levers (2) with support point (A) at 5th-reverse
synchronizer hub (3) presses 5th-reverse baulk ring (4).( )
3. Friction that is generated at 5-reverse baulk ring presses syn-
chronizer lever on 5th-reverse coupling sleeve. ( )
4. 5th-reverse coupling sleeve that is presses by synchronizer
lever stops the rotation of input shaft. JPDIC0415ZZ
