COVER 2002045 - Caterpillar

Personal injury or death can result from a machine moving during driveshaft removal and installation.Block the wheels securely so that the machine cannot move.The towing connection must be rigid, or towing must be done by two machines of the same size or larger than the towed machine. Connect a machine on each end of the towed machine.
This machine is equipped with a parking brake that is spring-applied and electro-hydraulically released. If the engine or the system for brake pressure is inoperable, the parking brake is applied and the machine cannot be moved.These towing instructions are for moving a disabled machine for a short distance at low speed. Move the machine at a speed of 2 km/h (1.2 mph) or less to a convenient location for repair. Always haul the machine if long distance moving is required.This machine can be towed by removing the drive shaft from the machine. Refer to the machines Service Manual or consult your Cat dealer for the removal procedure for the drive shaft and for the installation procedure for the drive shaft.Shields must be provided on both machines. This will protect the operator if the tow line or the tow bar breaks.Do not allow an operator to be on the machine that is being towed unless the operator can control the steering and/or the braking.Before you tow the machine, make sure that the tow line or the tow bar is in good condition. Make sure that the tow line or the tow bar has enough strength for the towing procedure that is involved. The strength of the tow line or of the tow bar should be at least 150 percent of the gross weight of the towing machine. This requirement is for a disabled machine that is stuck in the mud and for towing on a grade. Only attach the tow line to the towing eyes on the frame, if equipped.Do not use a chain for pulling a disabled machine. A chain link can break. This may cause personal injury. Use a wire cable with ends that have loops or rings. Put an observer in a safe position in order to watch the pulling procedure. The observer can stop the procedure if the wire cable starts to break. Stop pulling whenever the towing machine moves without moving the towed machine.Keep the tow line angle to a minimum. Do not exceed a 30 degree angle from the straight ahead position.Quick machine movement could overload the tow line or the tow bar. This could cause the tow line or the tow bar to break. Gradual, steady machine movement will be more effective.Normally, the towing machine should be as large as the disabled machine. Make sure that the towing machine has enough brake capacity, enough weight, and enough power. The towing machine must be able to control both machines for the grade that is involved and for the distance that is involved.You must provide sufficient control and sufficient braking when you are moving a disabled machine downhill.
