ROCKER ARM AS 2941695 - Caterpillar

Pressurized System!Hydraulic accumulators contain gas and oil under high pressure. DO NOT disconnect lines or disassemble any component of a pressurized accumulator. All gas pre-charge must be removed from the accumulator as instructed by the service manual before servicing or disposing of the accumulator or any accumulator component.Failure to follow the instructions and warnings could result in personal injury or death.Only use dry nitrogen gas to recharge accumulators. See your Cat dealer for special equipment and detailed information for accumulator service and charging.
Personal injury or death can occur if steering is lost completely during operation.Do not continue to operate the machine using the secondary steering.If the secondary steering activates during operation, immediately park the machine in a safe location. Inspect the machine and correct the condition which made the use of the secondary steering necessary.
Personal injury or death can occur if personnel are trapped between the wheel and the frame.The steering system is hydraulically controlled and wheels can crush personnel during movement.Use caution when working between the wheels and the frame. If the wheels must be turned, ensure that all personnel are clear of the machine before any movement.
This machine is equipped with a secondary steering system. The hydraulic steering accumulators provide a limited amount of stored hydraulic pressure for steering if the power source for the normal steering system fails or the engine stops. The secondary steering system will only provide steering until the stored hydraulic pressure is exhausted from steering action by the operator.

Illustration 2 g02791577Perform the following field test to verify that the secondary steering system is functional. Perform the test when the dump body is empty.
Prepare the machine for maintenance. Refer to Operation and Maintenance Manual, "Prepare the Machine for Maintenance".
When the engine is stopped with the engine start switch, check the steering hydraulic oil level. Maintain the oil within green range (A) of upper sight gauge (2).
After engine start-up, check the oil level.
If the oil level within green range (B) of lower sight gauge (3) is proportional to the oil level within the green range of the upper sight gauge level in step 2, the accumulators are properly charged.
If the oil level is below the green range in the lower sight gauge, check accumulator charge before proceeding to the next step. Refer to System Operation, Testing and Adjusting, KENR8574, "793F Off-Highway Truck Steering System", "Accumulator (Steering) - Test and Charge" or consult your Cat dealer.
Turn the front wheels to the straight ahead position.
Chock the rear wheels and move the transmission control in the N position.

Stop the engine with ground level shutdown switch (4). This permits the accumulators to stay charged to provide stored energy for the secondary steering system when the engine is stopped.
Visually confirm the following:
Verify that the front wheels turn left as the steering wheel is turned left.
Verify that the front wheels turn right as the steering wheel is turned right.If the secondary steering system is unable to comply with any portion of this field
