Usage:
Remove Track Brakes
START BY:
a. remove final drives
1. Disconnect oil lines (3) from housing (5).
2. Remove bolts (1) and oil manifold (2).
3. Loosen bolts (4) evenly to release the tension in the springs in housing (5) for the track brake. Remove bolts (4) and housing (5).
4. Bend the ends of two short pieces of wire. Use the wires to remove discs (6) and plates (7) from ring (8).
5. Remove ring (8) from the final drive case only if a replacement is necessary.
Install Track Brakes
1. Put 6V6640 Gasket Maker on the outside diameter of ring (2). Install ring (2) on the final drive case with the holes in the ring in alignment with the bolt holes in the case.
2. Put clean SAE 30 oil on each brake disc (3) and brake plate (1) before assembly.
NOTE: A brake disc is made of friction material, and there are five discs for each track brake. A brake plate is made of steel, and there are four plates for each track brake.
3. Install brake discs (3) and brake plates (1) in ring (2). Start and stop with a brake disc.
4. Put brake housing (4) in position on the ring with the holes in the brake housing in alignment with the holes in the ring, and install the bolts that hold it in place.
5. Put oil manifold (5) in position on the final drive case, and install the bolts that hold it in place.
6. Connect oil lines (6) and (7) to the brake housing.

Disassemble Track Brakes
START BY:
a. remove track brakes
1. Put two bars (1) across the plate as shown. Bars (1) are flat pieces of steel approximately 16.5 cm x 31.8 mm x 6.4 mm (6 1/2 in. x 1 1/4 in. x 1/4 in.). Put ring (2) over the bars as shown, and install two bolts (3) through ring (2) and the housing, and install washers and nuts on the bolts. Bolts (3) are 3/8"-16 NC bolts, 5 in. long. Tighten bolts (3) evenly to put the springs in the track brake in compression. Use a soft hammer to push piston (4) through the plate so ring (5) can be removed. Use tool (A) to remove ring (5) from the piston.
 |
Bolts (3) are used to hold the springs in the track brake in compression so ring (5) can be removed. Ring (2), bars (1) and plate (6) can be released rapidly and cause injury if the tension in the springs is not released before bolts (3) are completely removed. Be sure all the tension in the springs is released before bolts (3) are removed. |
 |
2. Loosen bolts (3) evenly to release the tension in the springs in the track brake.
3. Remove bolts (3), ring (2), bars (1) and plate (6) from the track brake housing.
4. Remove two springs (7) from the track brake housing.
5. Use a soft hammer to push piston (4) out of the track brake housing.
6. Remove O-ring seal (8) from the parking brake housing.
7. Remove seal assemblies (9) and (10) from the piston.
Assemble Track Brakes
NOTE: Put clean oil on all parts before assembly.
1. Install seals (1) and (2) on the piston as shown.
2. Install piston (3) in the track brake housing as shown.
3. Install O-ring seal (4) on the track brake housing.
4. Install springs (5) in the track brake housing as shown with the inside diameters of the springs together and the outside diameters apart.
5. Install plate (10) with the counterbore for the ring up.
6. Put two bars (6) across plate (10) as shown. Bars (6) are flat pieces of steel approximately 16.5 cm x 31.8 mm x 6.4 mm (6 1/2 in. x 1 1/4 in. x 1/4 in.) Put ring (7) over the bars as shown, and install two bolts (8) through ring (7) and the housing, and install washers and nuts on the bolts. Bolts (8) are 3/8"-16 NC bolts, 5 in. long. Tighten bolts (8) evenly to put the springs in the track brake in compression. Use a soft hammer to push the piston through the plate so ring (9) can be installed. Use tool (A) to install ring (9) in the groove in the piston.
7. Loosen bolts (8) evenly and let the springs in the parking brake push plate (10) over ring (9).
|
Ring (9) holds plate (10) in place. Plate (10) holds the springs in compression. Ring (9) and plate (10) can be released rapidly and cause injury if ring (9) is not completely engaged in the groove in the piston and counterbore in plate (10) before bolts (8) are removed. Do not remove bolts (8) until ring (9) is completely in the counterbore in plate (10) and engaged the groove in the piston. |
|
8. Remove bolts (8), ring (7) and bars (6) from the track brake housing.
