SHOE-CIRC GDE-YM 4194706 - Caterpillar

When the transmission is in First Speed Forward, No. 5 clutch (10) and No. 2 clutch (4) are engaged. The No. 2 clutch holds ring gear (5) 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. 2 sun gear (20). No. 2 sun gear turns No. 2 planetary gears (19). The No. 2 clutch holds ring gear (5) stationary. Then, planetary gears (19) rotate inside the ring gear. The movement of the planetary gears turns the No. 2 and No. 3 carrier (3) in the same direction as input shaft (14). 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). The No. 3 sun gear turns output shaft (15) .Ring gear (7) turns No. 4 carrier (12) . No. 4 planetary gears (16) are connected to No. 4 ring gear (9). Ring gear (9) is connected to hub (11) through the engaged No. 5 clutch. Power flows from carrier (12) to planetary gears (16), to ring gear (9), and to the No. 5 clutch. Then, power flows through hub (11) to output shaft (15) .As a result, torque to output shaft (15) is divided through No. 3 sun gear (17), through No. 4 sun gear (13), and through hub (11). From the
