MANIFOLD GP-EXHAUST 6I2298 - Caterpillar

engine speed as required.Extended operation at low idle or reduced load may cause increased oil consumption and carbon build-up in the cylinders. This carbon build-up results in loss of power and/or poor performance. When operating at reduced load, the engine should be fully loaded to burn excess carbon from the cylinders at least every four hours. Check the gauges and equipment frequently while operating under load.Gauges readings should be observed and the data recorded frequently while the engine is operating. Comparing the data over time will help determine normal readings for each gauge, and help detect abnormal operating developments. Significant changes in the readings should be investigated.Engine and Marine Transmission Operation
Shifting the Marine Transmission
Full power is transferred from the engine, through the marine transmission, to the propeller shaft. The power may be transferred in either forward or reverse rotation. The transmission forward and reverse drives can be operated by mechanical, hydraulic, pneumatic, or electrically actuated controls.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 transmission selector lever, which can be remotely operated (from the pilot house), or operated manually from the transmission (in the engine room).Marine transmission is usually operated from the pilot house. Pilot house controls must be adjusted so as to permit full travel of the transmission selector lever, and full engagement of the clutch plates.With the remote controls properly adjusted, periodic clutch adjustment is not required.Moving and Getting Underway
For best performance and maximum service life, shifting the marine transmission must be done in the following specific manner. To get underway after the engine has started and is warm:1. Fully engage the marine transmission selector lever in the desired direction of travel.2. Wait a sufficient amount of time to allow complete engagement of the clutch. Allow at least two seconds before increasing engine speed.3. Gradually increase engine speed as required.
Operate the transmission controls ONLY with the engine running. A rotating propeller shaft with an engaged clutch is not lubricated sufficiently when the engine is not running, and may be damaged.
Docking or Traveling (Direction Change)
Do not shift across the NEUTRAL position without a few seconds delay. The engine torque must be able to overcome the propeller and drive line inertia, the marine transmission inertia, and the propeller slip stream torque.A direct through-shift will cause severe shock loads to the engine, marine transmission and hull. Also, it can cause the engine to reverse its rotation (run backwards). If the engine reverses rotation, the engine and marine transmission oil pumps will be running opposite normal rotation. Oil will not reach the bearings, and severe engine damage will occur.When reversing direction of travel (propeller rotation), reduce engine speed to low idle. Place the transmission selector lever in NEUTRAL for approximately two seconds to allow the clutch plates to completely disengage and the propeller to stop turning. Move the lever to the other direction and allow two seconds in the position for the clutch
