D     6V-6640     Sealant     1    Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement.Note: When brake service is required, replace both friction discs. Replace all piston seals and all retraction springs. Inspect all surfaces for wear. Replace components, as required.

Install bolt (19) and plug (18) in axle housing (2). Tighten bolt (19) to a torque of 0.45 0.05 N m (4 0.4 lb in).
Apply Tooling (C) to dowel (7). Install dowel (7). Seat dowel (7) in the bottom of the bore.
Apply clean SAE 30W power train oil to O-ring seal (8). Lubricate O-ring seal (8) and pin (9) heavily with the oil that is being sealed. Install O-ring seal (8) and install pin (9) .

Note: Apply Tooling (C) to dowel (12) before installation.
If necessary, install dowels (6) and (12). Seat the dowels in the bottom of the bores.
Install the rubber portion of seal assembly (16) first, as shown. Install the backup ring of the seal assembly. Make sure that the inside rounded edge of the backup ring is toward the rubber seal. A permanent color mark indicates the side of the backup ring with the rounded edge.
Install seal (17) .
Apply petroleum jelly to seal assembly (16) and seal (17) .
Apply clean hydraulic oil to piston (15) .Note: Install piston (15) evenly. Twisting or binding of the piston may cause seal damage.
Install piston (15) in the differential housing assembly.Note: Using a friction disc with less than 7.65 mm (0.301 inch) of friction material will result in accelerated wear. Do not use the color of the friction disc as an indication of wear. The overall thickness and disc groove depth are better indications of wear.
Inspect friction disc (13) for wear. Replace friction disc (13) if the thickness of the friction material is less than 7.65 mm (0.301 inch). Immerse the friction discs in clean SAE 30W oil. Install friction disc (13) .
Install cup (11) and spring (10) .
Install two springs (5) .
Install reaction plate (4) .

Improper assembly of parts that are spring loaded can cause bodily injury.To prevent possible injury, follow the established assembly procedure and wear protective equipment.
Apply Tooling (D) on the mating surfaces of the axle housing and differential housing.
Fasten Tooling (A) and a suitable lifting device to the rim of the
