Personal injury or death could result when towing a disabled machine incorrectly.Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.Follow the recommendations below, to properly perform the towing procedure.
This machine is equipped with spring applied, hydraulic pressure released brakes. If the engine or power train hydraulics are inoperable, the brakes are applied and the machine can not be moved.These towing instructions are for moving a disabled machine a short distance, only a few feet at low speed, no faster than 2 km/h (1.2 mph), to a convenient location for repair. These instructions are for emergencies only. Always haul the machine if long distance moving is required.Shielding must be provided on the towing machine, to protect the operator if the tow line or bar should break.Do not allow riders on the machine being towed, unless the operator can control the steering and/or braking.Before towing, make sure the tow line or bar is in good condition and has enough strength for the towing situation involved. Use a towing line or bar with a strength of at least 1.5 times the gross weight of the towing machine, for a disabled machine stuck in mud or when towing on a grade.Keep the tow line angle to a minimum. Do not exceed a 30° angle from the straight ahead position.Quick machine movement could overload the tow line or bar and cause it to break. Gradual and smooth machine movement will work better.Normally, the towing machine should be as large as the disabled machine. Satisfy yourself that the towing machine has enough brake capacity, weight and power, to control both machines for the grade and distance involved.To provide sufficient control and braking when moving a disabled machine downhill, a larger towing machine or additional machines connected to the rear could be required. This will prevent it from rolling uncontrolled.The different situation requirements cannot be given, as minimal towing machine capacity is required on smooth level surfaces to maximum on inclines or poor surface conditions. Consult your Caterpillar dealer for towing a disabled machine with inoperable engine. The engine must be operable or a power pack available to provide steering pressure. See "Towing Instruction."Towing with Final Drive, Differential and Transmission Failure and Operable Engine
1. Engage the parking brake.2. Remove "U" joint at the converter. 3. Remove sun gears from axle shafts.4. Start the engine, as long as the failure is not in the converter system.5. Turn the steering wheel right and left to check the steering.
Do not tow faster than 2 km/h (1.2 mph).
6. Hook up tow machine.7. Release the parking brake, pull with tow machine and apply the service brake on the disabled truck to check braking. Release the brakes if functioning.8. Before returning the machine to work, install the torque converter "U" joint and the sun gears to the axle shafts.
