BW 47-36 Transfer Case Service Manual

SECTION 1. INTRODUCTION AND DESCRIPTION

1-1. INTRODUCTION

This manual contains maintenance, service and parts information for the 47-36 Transfer Cases manufactured by BorgWarner TTS (Beijing) Co., Ltd.

As you will see in the Table of Contents, this manual provides information for maintenance,

troubleshooting, installation, removal, disassembly, cleaning, inspection, repair or replacement, and assembly of transfer case.

Section 7 lists special tools. These tools, or equivalent are required for proper disassembly and assembly of the transfer case.

The exploded view illustrations in Section 8 make it possible to view the complete assembly in addition to the illustrations in the service sections relating to a specific service procedure.

1-2. DESCRIPTION

The BW 47-36 is a two-speed, part time transfer case. A planetary gear set is used to provide gear reduction. Power is transferred to the front wheel drive through a Morse Hy-Vo chain drive. The unit operates in an oil bath plus an oil pump is used to provide positive lubrication to the planetary gear set and other upper shaft components. Three selector positions are provided: 2H — In two high position, only the two rear wheels are driven and the transfer case operates at a 1.00 to 1.00 speed ratio.

4H — In four high position, all four wheels are driven at a 1.00 to 1.00 speed ratio.

4L — In four low position, all four wheels are driven and the transfer case operates at a 2.48 to 1.00 speed reduction ratio.

The electric shift transfer case is controlled by an electric clutch, a speed sensor and an electric motor that drive a shift cam within the case. A separate electronic shift control system is also necessary. The clutch is used to spin up the front drive system and permit shifting from 2H to 4H at any speed.

The 47-36 transfer case is used for SUV & light truck applications.

The identification tag is installed on the transfer case at the location shown in Figure 1-1. Figure 1-1 also illustrates the information to be found on the tag.
