7D-2 TRANSFER
The transfer is mounted on transmission case by fastening bolts with reduction drive gear in transfer and differ-
ential case in transmission coupled by involute spline. Driving force from transmission is transmitted to propeller
shaft through reduction drive gear, reduction driven gear and bevel gears in transfer. As bevel gears, which
change the direction of driving torque axis to the direction of the angle with 90 degrees, hypoid gears are pro-
vided. Hypoid gears have an advantage of preventing gear noise, at the same time, they require accurate
adjustment of tooth contact and backlash.
