9.10 Installing the Brake and Brake Cable
Prerequisites Appropriate crane and sling
Procedure Follow the procedure below to install the brake.
1. Raise the rear half of the machine approximately 10 cm (4 in.) off the rear drum.
2. Away from the machine, loosely install the four screws (i) and nuts that hold the brake
caliper (j) together; do not tighten the nuts. Slide the brake caliper around the drive
plate; then tighten the four screws (i) and nuts.
3. Place the brake caliper into position so that when installed the two screws (h) will hold
the brake caliper. Then, using Loctite 243 or an equivalent on the two screws, secure
the two screws to the brake bracket.
4. Lower the rear half of the machine and reconnect the drive plate to the shock mounts.
Torque the screws to 76 Nm (56 ft.lbs.).
5. Install the spring (l) and the arm (k).
6. Install the castle nut (j) and the cotter pin (i).
