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.

SECTION 4. CLEANING, INSPECTION, REPAIR OR
REPLACEMENT
4-1. CLEANING
NOTE: Prior to cleaning, check magnet for presence of metal particles. Larger, granular or irregular shaped particles indicate chipping or similar damage. Smaller, powder-like particles indicate uneven or excessive wear. If metal particles are detected, be on the lookout for damage or wear when inspecting rotating part and those with which they mate.
4-1-1. GENERAL CLEANING PROCEDURE
Wash parts in cleaning solvent to remove old lubricant and dirt deposits. Use a bristle brush to remove caked-on deposits. Parts that cannot be cleaned by brushing may be scraped but use care not to damage metal surfaces.
4-1-2. DRYING CLEANED PARTS
Dry parts with low pressure (20 psi max) compressed air. Wiping parts dry could leave lint deposits. Hold bearings to prevent them from spinning when drying.
4-1-3 LUBRICATING BEARINGS
Immediately after cleaning, lubricate ball bearings (8, 12, 52 and 53) and needle bearing (14) with transfer case lubricant. Rotating or spinning dry, unlubricated bearings could result in damage. Cover lubricated bearings to protect from dust.
4-2. INSPECTION
4-2-1. GENERAL INSPECTION PROCEDURE
Visually inspect all parts (except hose coupling, O-ring and oil seals, which should be replaced with new parts) for damage or excessive or uneven wear. Reject parts with damage or wear that would affect serviceability of the part. Inspection terms used in this section are as follows:
Burr: Local rise of material forming protruding sharp edge.
Chip: An area from which a small fragment has been broken off or cut.
Crack: Surface break of line nature indicating partial or complete separation of material.
Excessive wear: Heavy or obvious wear beyond expectations considering conditions of operation. Indentation: Displacement of material caused by localized heavy contact.
Galling: Breakdown (or build-up) of metal surface due to excessive friction between parts. Particles of the softer material are torn loose and welded to the harder material.
Nick: Local break or notch. Usually displacement of material rather than loss.
Scoring: Tear or break in metal surface from contact under pressure. May show discoloration from heat produced by friction.
Step wear: Heavy wear that produces a step that can be seen or felt between adjacent contact and noncontact surfaces.
Uneven wear: Condition of localized, unevenly distributed wear. Includes hollows, shiny spots, uneven polish and other visual indications.
4-2-2. SPECIFIC INSPECTION PROCEDURES
Inspect parts in accordance with table 4-1 and as specified in the following paragraphs. Index numbers used in Table 4-1 are those assigned to the exploded view in Section 8.
4-2-3. GEAR OR SPROCKET TEETH INSPECTION
When specified in Table 4-1, inspect gear or sprocket teeth as follows:
NOTE: Do not confuse contact patterns with normal tool marks that are a result of manufacture. Typical tool marks are shown in Figure 4-1.
a.Check gear or sprocket tooth contact patterns. Contact patterns likely to be encountered are
shown in Figure 4-2. Parts with contact patterns shown in the ACCEPT column are OK for further service provided they meet all other inspection requirement. Parts with contact patterns shown in REJECT column are unacceptable and must be rejected – no repairs are authorized.
b.Check gear or sprocket teeth for chips. Compare tooth chips or nicks with those shown in Figure
4-3. Parts with small chips as shown in REPAIR column may be blend-repaired (refer to paragraph 4-2-4) and reused. Chips or broken teeth as shown in REJECT column are not repairable and the part must be rejected.
4-2-4. SPLINE TEETH INSPECTION
Check for broken or chipped spline teeth. Small chips may be blend-repaired in same manner as gear teeth (see Figure 4-2 and refer to paragraph 4-). If any spline tooth is broken, the part must be rejected. Spline teeth will not show contact patterns as gear teeth do. However, they may show evidence of step wear which is cause for rejection.
4-3. REPAIR OR REPLACEMENT
Parts which are rejected at inspection shall be replaced unless repair procedures specified in the following paragraphs, or other obvious minor repair, will restore the part to complete serviceability.
4-3-1. GEAR AND SPROCKET TOOTH REPAIR
Repair shall be limited to blend-repair of chips within the limits shown in Figure 4-3.
a.Blend-repair chips using a suitable hand-held, high speed grinding tool.
b.Blend chip into surrounding base metal, but do not remove any more metal than necessary.
c.Blend all sharp edges into smooth contour. Sharp edges may chip again or develop cracks.
4-3-2. REMOVING SMALL BURRS
Use a suitable abrasive stone to remove burrs. Be careful to remove only raised material, not base metal.
4-3-3. PARTS REPLACEMENT
Replace rejected parts that are not repairable. If there is any doubt about the serviceability of a part, replace it.
Table 4-1. Inspection
