SPACER 2802072 - Caterpillar

The BrakeSaver provides auxiliary braking to slow the truck and to control speed on long grades. Governing the deceleration or downgrade speed of a vehicle by using the BrakeSaver results in greater safety, and reduces wear on brake linings and brake drums. It helps save the service brakes for emergency stopping requirements.Braking effort is a direct function of engine speed. The greater the engine speed the greater the braking effort.The BrakeSaver utilizes the engine oil and cooling systems and eliminates the need for additional oil or cooling systems.When changing the engine crankcase lubricating oil, it is also necessary to drain the oil from the oil cooler. Remove the drain plug located on the bottom of the BrakeSaver control valve.Make a frequent check of coolant and oil lines for leakage and deterioration of hoses. If an oil or water leak develops, do not operate the engine until proper repairs can be made.Scheduled maintenance on the BrakeSaver, or additional engine maintenance, is not required.Trucks equipped with the BrakeSaver require an additional amount of engine lubricating oil. See the LUBRICATION AND MAINTENANCE CHART for service intervals.At oil change intervals, fill the crankcase to the proper level. Operate the engine for a short period. Stop the engine and check the engine oil level. Be sure it is at the full mark on the dipstick. Add oil if necessary. MANUAL CONTROL: The hand operated control lever, usually mounted on the steering column, provides a smooth modulated application of the BrakeSaver to apply any desirable retarding of the vehicle, up to engine rating. This controlled modulation of the BrakeSaver is especially desirable on slippery roads. Increasing or decreasing the BrakeSaver action is accomplished by moving the control lever. AUTOMATIC CONTROL: The mode selector switch must be in the AUTOMATIC MANUAL position for automatic control. The BrakeSaver will then automatically shut off when the clutch is disengaged. It will engage again when the clutch is re-engaged.Slight accelerator pressure will turn off the BrakeSaver. This will allow the truck to coast and be retarded only by engine friction and normal rolling resistance. GAUGES: The BrakeSaver CONTROL AIR PRESSURE gauge indicates the pressure at the BrakeSaver control valve. Air pressure should not exceed 50 psi (345 kPa).If the indicator shows reduced or no pressure, stop the vehicle or operate at a reduced speed. Control vehicle stopping with proper downshifting and service brakes until proper repairs are made.The BrakeSaver oil temperature gauge indicator should register in the NORMAL (green) range. If the indicator moves to the red range, move the BrakeSaver manual control lever to the OFF position.Operate the vehicle with the service brakes only, or stop the vehicle and let the engine idle until the oil temperature registers in the NORMAL range. No special skills are required to operate a vehicle with a BrakeSaver. However, it requires the driver to watch the engine speed and the BrakeSaver oil temperature.For maximum BrakeSaver effectiveness, select the proper gearing to keep the engine RPM as close to the rated speed
