SHAFT-SUN GEAR 3677421 - Caterpillar

Hauling
Do not use the retarder control as a parking brake or to stop the machine.
Pay attention to your surroundings. Keep a safe distance from any machines in front of your machine.Do not drive over unprotected power cables. Do not drive under low overhead power cables.Know the maximum height of the machine. Know the maximum width of the machine. Maintain proper clearances.Always travel with the hoist control in the FLOAT position. Shift to the top speed that is anticipated. All further shifts will be automatic.During normal operation, use the service brake for all normal braking.Roads can be slick from ice or from snow. Also, roads can be slick from being wet. Reduce the speed of the machine in order to compensate for poor ground conditions.Traveling Down a Grade
Never coast down a grade in NEUTRAL. Always keep the transmission in gear. When the machine speed is greater than 8 km/h (5 mph), the Power Train Electronic Control System will not allow you to shift from forward gear into NEUTRAL or into REVERSE.Use the Automatic Retarder Control (ARC) in order to sustain the machine at a constant speed on a downgrade that is long or steep. When approaching a downgrade, activate the ARC and select the desired gear before you start the downgrade. The actual gear of the transmission should also match the selected gear before you start the downgrade. See Operation and Maintenance Manual, "Retarding" for further information.Determine the proper gear for the conditions, the load, and the downgrade. If you do not know the proper gear, use the common practice of selecting the gear that is required to go up the grade when the machine is loaded.See Operation and Maintenance Manual, "Retarding" for further information.Preventing Overspeed
If the machine builds up excessive speed, use the retarder control (lever) in order to reduce the vehicle speed. If braking force is needed, use the service brake. See Operation and Maintenance Manual, "Retarding" for further information.Note: If the engine reaches 2300 rpm and the transmission is in the same gear as the transmission direction and speed control, the transmission will upshift one gear. If the transmission is in the top gear, the torque converter lockup clutch will disengage.
Do not shift into the NEUTRAL position and do not freewheel down a grade.If the brake oil temperature gauge enters the red range, reduce the travel speed or stop the machine until the oil cools. This will prevent damage to the brake components.
Dumping and Spreading
Positioning
Personal injury or death can occur when backing the machine over soft edges. Use care when backing into the dump area. Stay clear of soft edges that could collapse under the machine.If the load is frozen in the machine bed and dumping is attempted on a slope, the machine can tip over causing personal injury or death.
Inspect the dump area before you bring in a loaded truck.Take care when you drive into the dump area. Maintain a safe distance from other machines.Avoid hitting sharp rocks.Be certain that no personnel are near the
