CORE AS-RADIATOR 1363851 - Caterpillar

Personal injury or death can result if two persons are not used in the following procedure.Make reference to the on the first page of the Testing And Adjusting section.
1. Position the machine so that it is level from side-to-side. Stop the engine and engage the parking brake.2. Lower the oil level in the axle housing to a point below the bottom of the inspection ports.3. Remove the inspection plug which corresponds to the brake disc to be checked. Oscillation of the rear axle may provide better access to the inspection ports.4. Depress and hold either brake pedal. This will hold piston (1), disc (2), and plate (3) tight against one another.5. Using a feeler gauge, measure the distance between the ear cast into the brake piston (at the inspection port area), and the plate.6. The minimum thickness [dimension (A)] of disc (2) worn is 7.65 mm (.301 in). The thickness [dimension (A)] of disc (2) new equals 9.10 0.13 mm (.358 .005 in). Service the brake before the thickness [dimension (A)] of disc (2) is less than 7.65 mm (.301 in).
Measuring Depth Of Brake Disc Oil Grooves Groove depth is the most critical dimension. If the depth of the grooves on the brake discs are too shallow or nonexistent, oil flow will be inadequate and cause excessive wear and abrasion. See the chart.7. Using a wire gauge, measure the depth of the oil grooves on BOTH sides of the service brake disc in each service brake axle housing.8. The minimum depth of the oil grooves must not be less than 0.32 mm (.013 in). Operation Checks
Personal injury can result if the machine moves while testing.If the machine begins to move during a test, reduce the engine speed immediately and engage the parking brake.Make reference to the on the first page of Brake System Testing And Adjusting section.
Service Brake Test Procedure
Be sure the area around the machine is clear of personnel and obstructions.Be sure the steering frame lock link is in the stored position.Test the service brakes on a dry, level surface.Fasten the seat belt before testing the brakes.1. Start the engine, and raise the bucket slightly.2. Place the transmission neutralizer switch in the OFF position.3. Apply the service brake and release the parking brake.4. Move the transmission to third speed forward.5. Gradually increase the engine speed to high idle. The machine should not move.6. Reduce the engine speed to low idle, move the transmission to NEUTRAL. Engage the parking brake, lower the bucket to the ground and stop the engine.
If the machine moved while testing the service brakes, inspect and repair the service brake components as required before returning the machine to service.
Parking Brake Test Procedure
Be sure the area around the machine is clear of personnel and obstructions.Be sure the steering frame lock link is in the stored position.Test the brakes on a dry, level surface.Fasten the seat belt before performing the following brake test.1. Start the engine, and raise the bucket slightly. The following step
