HYDRAULIC PUMP ASSEMBLY 3A1692 - Caterpillar

Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of the engine components. Allow the engine to engine cool down before stopping. Avoiding hot engine shutdowns will maximize turbocharger shaft and bearing life.
Emergency Stopping
Emergency shutoff controls are for EMERGENCY use ONLY. DO NOT use Emergency shutoff devices or controls for normal stopping procedure.
Make sure that any external system components that have been operating to support engine operation are secured after any stop.Emergency Stop Button
Emergency Stop Button, shown mounted on a junction box.Emergency stops may be made by pushing the Emergency Stop Button located on the junction box (if equipped). The button requires resetting before the engine will start.Manual Stop Procedure
There may be several ways to shut off your engine. Make sure the shutoff procedures are understood. Use the following general guidelines for stopping the engine.1. Open the main electrical circuit breaker to remove the load.2. The engine should be run for a cool down period before being shut off. This can be accomplished with a COOLDOWN STOP function (if equipped), or the operator can control the cool down and shut off.3. The engine may be stopped by using the Woodward PSG Governor control lever (if equipped), or the mechanical governor control (if equipped).A manual shutoff shaft is provided to override the governor control. The shaft will move the fuel control linkage to the FUEL OFF position.
Woodward PSG Governor control lever.If equipped with a Woodward PSG Governor, move the control lever upward or forward, depending on the installation. Hold the lever at the FUEL OFF or STOP position until the engine stops.
Typical mechanical governor controlMove the mechanical governor control to the FUEL OFF position. Hold the lever at the FUEL OFF position until the engine stops.After Stopping the Engine
* Check the crankcase oil level. Maintain the oil level between the ADD and FULL marks on the dipstick.* Repair any leaks, perform minor adjustments, tighten loose bolts, etc.* Note the service hour meter reading. Perform periodic maintenance as instructed in the Maintenance Schedule.* Fill the fuel tank to prevent accumulation of moisture in the fuel. Do not overfill.
Only use antifreeze/coolant mixtures recommended in the Cooling System Specifications of this manual. Failure to do so can cause engine damage.
* Allow the radiator and engine jacket water system to cool. Check the coolant level. Maintain the cooling system to 13 mm (1/2 inch) from bottom of the fill pipe.If freezing temperatures are expected, check the coolant for proper antifreeze protection. The cooling system must be protected against freezing to the lowest expected ambient (outside) temperature. Add the proper coolant and water mixture if necessary.
