TUBE AS 3465305 - Caterpillar

When the transmission is in FIRST SPEED FORWARD, Number 5 clutch (4) and Number 2 clutch (10) are engaged. The Number 2 clutch holds ring gear (23) stationary. The Number 5 clutch connects rotating hub (3) to Number 4 carrier (5) and ring gear (22) .Input shaft (1) turns Number 2 sun gear (11) . The Number 2 sun gear turns planetary gears (24) . Because ring gear (23) is held stationary by the Number 2 clutch, planetary gears (24) move around the inside of the ring gear. The movement of planetary gears (24) causes No. 2 carrier (9) and No. 3 carrier (9) to turn in the same direction as input shaft (1) .As carrier (9) turns, planetary gears (21) turn ring gear (22) and sun gear (7) . Sun gear (7) turns output shaft (2) .Ring gear (22) turns carrier (5) . Carrier (5) is connected to rotating hub (3) by the engagement of Number 5 clutch (4) . This allows power to travel from carrier (5) to sun gear (18) . The power then travels through Number 5 clutch to rotating hub (3) . Sun gear (18) and rotating hub (3) are fastened to output shaft (2) .As a result, the torque to output shaft (2) is divided between Number 3 sun gear (7) , Number 4 sun gear (18) , and rotating hub (3) . From the output shaft, power travels through the output transfer gears to the differentials.Second Speed Forward
When the transmission is in SECOND SPEED FORWARD, Number 4 clutch (6) and Number 2 clutch (10) are engaged. The Number 2 clutch holds ring gear (23) for the Number 2 clutch stationary. The Number 4 clutch holds ring gear (20) for the Number 4 clutch stationary. Input shaft (1) turns Number 2 sun gear (11) . Number 2 sun gear turns Number 2 planetary gears (24) .Because ring gear (23) is held stationary by the Number 2 clutch, planetary gears (24) move around the inside of the ring gear. The movement of planetary gears (24) causes No. 2 carrier (9) and No. 3 carrier (9) to turn in the same direction as input shaft (1) . As the Number 2 carrier and the Number 3 carrier turn, Number 3 planetary gears (21) turn. The Number 2 planetary gears turn ring gear (22) for the Number 3 clutch and Number 3 sun gear (7) . Number 3 sun gear (7) turns output shaft (2) . Ring gear (22) turns Number 4 carrier (5) .Because ring gear (20) is held stationary by the Number 4 clutch, planetary gears (19) move around the inside of the ring gear. The movement of planetary gears (19) causes Number 4 sun gear (18) to turn. The Number 4 sun
