Third Speed Forward
When the transmission is in Third Speed Forward, No. 2 and No. 3 clutches are engaged.The No. 2 clutch holds ring gear (5) for the No. 2 clutch stationary.The No. 3 clutch holds ring gear (7) for the No. 3 clutch stationary. Input shaft (14) turns No. 2 sun gear (20). No. 2 sun gear turns No. 2 planetary gears (19) .Ring gear (5) is held stationary by the No. 2 clutch. Then, planetary gears (19) rotate inside the ring gear. The movement of planetary gears (19) turns No. 2 and No. 3 carrier (3) in the same direction as input shaft (14) .Ring gear (7) is held stationary by the No. 3 clutch. The movement of No. 2 and No. 3 carrier (3) turns No. 3 planetary gears (18) inside the ring gear.The movement of planetary gears (18) turns No. 3 sun gear (17). No. 3 sun gear turns output shaft (15). From the output shaft, power flows through the transfer and bevel gears to the steering differential and planetary gears.First Speed Reverse
Illustration 5 g01221212
Power flow with the transmission in First Speed Reverse. The No. 1 clutch and No. 5 clutch are engaged.The clutches are identified within the numbered circles. (1) Coupling gear (2) Reverse (No. 1 Clutch) (3) Carrier (No. 2 and No. 3 Clutches) (6) Third speed (No. 3 Clutch) (7) Ring gear (No. 3 Clutch) (8) Second speed (No. 4 Clutch) (9) Ring gear (No. 4 Clutch) (10) First speed (No. 5 Clutch) (11) Hub (12) Carrier (No. 4 Clutch) (13) Sun gear (No. 4 Clutch) (14) Input shaft (15) Output shaft (16) Planetary gear (No. 4 Clutch) (17) Sun gear (No. 3 Clutch) (18) Planetary gear (No. 3 Clutch) (21) Ring gear (No. 1 Clutch) (22) Planetary gear (No. 1 Clutch) (23) Sun gear (No. 1 Clutch) (24) Carrier (No. 1 Clutch)When the transmission is in First Speed Reverse, No. 1 clutch (2) and No. 5 clutch (10) are engaged. The No. 1 clutch holds ring gear (21) for the No. 1 clutch stationary. The No. 5 clutch connects hub (11) to No. 4 carrier (12) and to No. 3 ring gear (7) .Input shaft (14) turns No. 1 sun gear (23). No. 1 sun gear turns No. 1 planetary gears (22). No. 1 carrier (24) has a direct mechanical connection with ring gear (21) .Ring gear (21) and No. 1 carrier (24) are held stationary by the No. 1 clutch. The rotation of No. 1 planetary gears (22) turns coupling gear (1) in the opposite direction as input shaft (14). Coupling gear (1) has a direct mechanical connection with No. 2 and No. 3 carrier (3). As the No. 2 and No. 3 carrier turns, No. 3 planetary gears (18) turn. The No. 3 planetary gears turn ring gear (7) for the No. 3 clutch. The No. 3 planetary gears also turn No. 3 sun gear (17). No. 3 sun gear (17) turns output shaft (15) .Ring gear (7) turns No.
