SECTION 3 POWER TRAIN SYSTEM SECTION 3 POWER TRAIN SYSTEM GROUP 1 STRUCTURE AND FUNCTION GROUP 1 STRUCTURE AND FUNCTION 1. POWER TRAIN COMPONENT OVERVIEW 1. POWER TRAIN COMPONENT OVERVIEW Transmission Engine Front drive shaft Center drive shaft Rear drive shaft Rear axle 760F3PT01 The power train consists of the following components: В Transmission В Front, center and rear drive shafts В Front and rear axles Engine power is transmitted to the transmission through the torque converter. The transmission is a hydraulically engaged four speed forward, three speed reverse countershaft type power shift transmission. A calliper-disc type parking brake is located on the transmission.
The transmission outputs through universal joints to three drive shaft assemblies. The front drive shaft is a telescoping shaft which drives the front axle. The front axle is mounted directly to the loader frame. The front axle is equipped with conventional differential as standard (option : Limited slip, Hyd lock differential). The rear axle is equipped with conventional differential as standard (option : Limited slip differential) The rear axle is mounted on an oscillating pivot. The power transmitted to front axle and rear axle is reduced by the pinion gear and ring gear of differential. It then passes from the differential to the sun gear shaft (axle shaft) of final drive.
The power of the sun gear is reduced by a planetary mechanism and is transmitted through the planetary hub to the wheel. 3-1 Front axle
