Transfer Case: Description and Operation

GENERAL DESCRIPTION
The aluminum transfer case directly connected to the back of the transmission contains the input gear, countershaft & gear, output rear shaft, output low gear and output front shaft (for front drive) connected by way of the hyvo-chain.

The transfer has such a selective mechanism as to enable the shift control lever to make selection of high speed (direct connection with transmission output: main shaft), low speed (speed reduction by input gear, counter gear and output low gear) or neutral by way of the reduction sleeve located between input gear and output low gear, and selection of two-wheel-drive (high speed only) or four-wheel-drive (high or low speed) by way of the front drive clutch sleeve located at the center of the output rear shaft.

The front drive shift fork has an auxiliary spring to make a smooth shift from 4H to 2H possible.

When reassembling the transfer after servicing, it is necessary, like with the transmission, to use sealant to seal the case and to tighten bolts exactly to the specified torque by using a torque wrench. Also, note that the case has an oil gutter to provide proper lubrication even under the strict conditions of use.

When towing the vehicle for the purpose of repair or the like, place the shift control lever to the N position and follow the towing instructions in OWNER'S MANUAL.
