High-Range Clutch and Power Takeoff (fig. 2-l). a. High-Range Clutch Components (fig. 2-1). (1) The high-range clutch consists mainly of housing (16), piston (15), piston return springs (58), four internal-splined, bronze-faced steel clutch plates, three external-tanged steel plates (17), and a steel reaction plate. (2) The housing (16) has a 6/8-pitch, 57- tooth power takeoff drive gear, integrally machined at its outer circumference. The housing has internal splines in the hub which connects it to the turbine shaft (59). (3) The external-tanged clutch plates (17) engage the housing (16). The internal-splined plates engage a hub which is integral with the intermediate-range planetary carrier (54). b. Operation of High-Range Clutch (fig. 2-1). (1) Power from the turbine (6) is transmitted to the clutch housing (16) through the turbine shaft (59) and the hub splines. When the clutch is released, the housing and three external-tanged clutch plates rotate but do not drive the four in- ternal-splined plates. When the clutch is applied, hydraulic pressure pushes the piston (15) rearward and compresses all seven clutch plates against the clutch reaction plate. This grips the internal-splined plates and causes them to rotate with the external- tanged plates and housing. The internal-splined plates drive the intermediate-range planetary carrier. (2) The housing (16) rotates when the turbine shaft (59) rotates. The shaft (59) rotates when the turbine (6) rotates. Thus, the housing (16) can rotate in neutral, reverse gear, or any forward gear when engine power is applied through the converter by speeding up the engine. For this reason the power takeoff drive gear is part of the housing. Its teeth mesh with a driven gear in the power take-off assembly (or assemblies) which may be mounted on either side of the housing (31). (3) In high-range operation, torque is trans- mitted at the same speed from the turbine shaft (59) to the intermediate-range planetary carrier assembly (54). The intermediate-range planetary carrier (54) is attached to the low-range ring gear (23). The low-range sun gear (46) is splined to the turbine shaft (39). Thus, two members of the low- range gear set are rotating at the same speed as the high-range clutch. The third member (low-range planetary carrier) is meshed with these two and, therefore. must also rotate at the same speed. This results in the transmission output shaft (33) being driven at the same speed as the turbine shaft (59). 2-3
