PIN AS 9R8594 - Caterpillar

Proper operation and maintenance are key factors in obtaining the maximum life and economy of the engine. If the directions in the Operation and Maintenance Manual are followed, costs can be minimized and engine service life can be maximized.The engine can reach normal operating temperature in less than the time for a walk-around inspection of the engine.The engine can be operated at the rated rpm after the engine reaches operating temperature. The engine will reach normal operating temperature sooner during a low engine speed (rpm) and during a low-power demand. This procedure is more effective than idling the engine at no load. The engine should reach operating temperature in a few minutes.Gauge readings should be observed and the data should be recorded frequently while the engine is operating. Comparing the data over time will help to determine normal readings for each gauge. Comparing data over time will also help detect abnormal operating developments. Significant changes in the readings should be investigated.Engine Speed Governing
The engine speed governor monitors the throttle position and the actual engine speed in order to help control the following items: engine speed, response, torque output and smoke limiting. The engine speed governor also helps to maintain constant engine speed.The engine speed is controlled by the governing of the fuel injection duration of the electronic unit injectors. Throttle input is used to calculate the desired engine speed.Engine Synchronization
Engine synchronization connects the Electronic Control Module (ECM) of the port engine and the ECM of the starboard engine to a common throttle. Engine synchronization increases the convenience of the operator and the control of the vessel. This feature is standard in marine applications.The engine synchronization enables either throttle to be used in a backup situation. The operator can use a switch to transfer the control of both engines to either the port throttle lever or starboard throttle lever. Refer to the Installation Guide for more information on engine synchronization.Engine and Marine Transmission Operation
Transmission Selector Lever
Power is transferred from the engine through the marine transmission to the propeller shaft. The marine transmissions can be operated by using one of the following methods:
Mechanical
Hydraulic
Pneumatic
ElectricalA control valve directs the flow of oil to the forward clutch or to the reverse clutch. The control valve is operated by a transmission selector lever. The transmission selector lever can be manually operated or remotely operated.Normally, the marine transmission is operated from the pilot house. The controls of the pilot house must be adjusted in order to permit full travel of the transmission selector lever. This will also permit full engagement of the clutch plates.When the remote controls are properly adjusted, periodic clutch adjustment is not required.Moving and Getting Underway
For the best performance and the maximum service life, shift the transmission in the following manner:
Fully engage the marine transmission selector lever in the desired direction of travel.
Wait for at least 3 seconds in order to allow the clutch to engage completely before increasing the rpm of the engine.
Gradually increase engine rpm.
Operate the marine transmission controls ONLY
