The torque converter and the transmission are bolted as a unit to the flywheel housing on the engine.Transmission (3) - The transmission has spur gears and helical gears that are in constant mesh on all shafts in order to provide a range of forward speeds and reverse speeds. The speed range and the direction (forward and reverse) are selected when the clutches and synchronizers lock specific gears to the shafts.Front axle differential (4) and rear axle differential (5) - Power is directed to the differentials from the transmission via drive shafts (6) and (7). Each of the differentials has a ring gear and a pinion (bevel gear set) in order to provide the primary reduction. The differential for the front axle can be locked in order to improve traction on adverse ground conditions.Final drives (8) for the front axle and final drives (9) for the rear axle - Power is transferred to the final drives for the front axle and to the final drives for the rear axle from differentials (4) and (5). The final drives in the front axle and in the rear axle have planetary gears. The planetary gears provide the secondary reduction.The torque converter and the transmission have a common hydraulic system for operation, for lubrication, and for cooling. The transmission case and the hydraulic tank serve as an oil reservoir. Oil flow through the system is provided by a pump that is mounted on the casing for the transmission.Machines are equipped with one of the following transmission arrangements:
Power Shuttle transmission with four speeds
Powersynchro transmission arrangement with four speeds
Powersynchro transmission arrangement with five speedsNote: The five speed Powersynchro transmission is an option on some machines. Your machine may not have this option. The transmissions with five speeds and the transmissions with four speeds are identical except for the added components for the fifth speed. The Power Shuttle transmission is identical to the Powersynchro transmission with the exception of the mechanism for shifting the transmission.Note: This machine must be serviced by a technician. The technician must be familiar with Caterpillar Electronic Technician (ET). A number of parameters can be installed and modified through the configuration screen. The configuration of the machine may appear as a interlock. See TESTING AND ADJUSTING, RENR5195, "ELECTRONIC CONTROL MODULE (ECM) - CONFIGURE" for information concerning the machine configuration.The clutches and the synchronizers for the Powersynchro transmission are engaged by oil pressure. The oil pressure is controlled by solenoid valves that are mounted on the transmission.
