V-BELT SET 7M4715 - Caterpillar

Proper operation and maintenance are key factors in obtaining the maximum life and economy of the engine. Following the directions in this manual will lower operating costs.The time needed for the engine to reach the normal mode of operation is usually less than the time taken for a walk-around inspection of the engine.After the engine is started and the cold low idle operation is completed, the engine can be operated at low speed and low power. The engine will reach normal operating temperature faster when operated at low speed and low power demand than when idled at no load. Typically the engine should reach operating temperature in a few minutes.
Operate the controls ONLY with the engine running. Report any needed repairs noted during operation.
Engine and Marine Transmission Operation
Operate a cool engine at low load. After normal oil pressure is reached and the temperature gauges begin to move, the engine may be operated at full load.Transmission Selector Lever
Typical ExampleFull power is transferred from the engine through the marine transmission, in either forward (1) or reverse (3) rotation, to the propeller shaft. The engine transmissions can be operated by mechanical, hydraulic, pneumatic or electrically actuated controls for the forward and reverse drives.A control valve directs the flow of oil to either the forward or reverse clutch (for forward or reverse operation). The valve is operated by a selector lever, which can be remotely operated (from the pilot station) or operated manually from the transmission (in the engine room).Moving and Getting Underway
The marine transmission selector valve is usually operated from the pilot house. It can also be operated at the marine transmission. Pilot house controls must be adjusted so as to permit full travel of the selector lever on the marine transmission, and full engagement of the clutch plates.To get underway after the engine has started and is warm:1. Fully engage the marine transmission control lever in the desired direction of travel. Allow one second before increasing engine speed.2. Wait a sufficient amount of time
