SUPPORT AS-FRONT 4W0664 - Caterpillar

Your engine may not have the same gauges or all of the gauges that are described. For more information about the gauge package, see the literature that is from the OEM of the vessel.Gauges provide indications of engine performance. Ensure that the gauges are in good working order. Determine the normal operating range by observing the gauges over a period of time.Noticeable changes in gauge readings indicate potential gauge or engine problems. Problems may also be indicated by gauge readings that change even if the readings are within specifications. Determine the cause of any significant change in the readings. Then, correct any cause of any significant change in the readings. Consult your Caterpillar dealer for assistance.Caterpillar requires two lamps in addition to the gauge package that is normally provided. The "Diagnostic" lamp is yellow or amber. The "Diagnostic" lamp will communicate the status of the electronic system of the engine. The "Warning" lamp is red. This red "Warning" lamp warns the operator of engine problems. The following conditions are some examples of the problems:
Low oil pressure
High coolant temperature
Low coolant level
High inlet air temperature
Be ready to activate the engine shutoff manually, if there is no oil pressure. Damage to the engine will result if the engine continues to run without the correct oil pressure.
Engine Oil Pressure - Typical oil pressure for 3176B Marine Engines at rated speed with SAE 10W30 or with SAE 15W40 is 207 to 340 kPa (30 to 50 psi). A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Reduce engine speed to low idle.
Shut down the engine, and allow time for the oil to settle back into the engine oil pan.
Check the oil level. Maintain the oil level at the proper amount.The diagnostic lamp will turn on if the oil pressure drops below a safe range. A safe range for the oil pressure is determined by the engine protection system. The diagnostic code will be logged in the Engine Control Module (ECM).
Engine Oil Temperature - This gauge indicates the engine oil temperature. Maximum oil temperature at rated speed with a full load is 104°C (220°F).
Transmission Oil Temperature - The typical range for the transmission oil temperature is 60° to 100°C (140° to 180°F). The normal operating range is 40° to 80°C (104° to 144°F). The transmission oil temperature depends on the temperature and the quantity of water that is pumped through the transmission oil cooler. Some marine transmissions have raw water that is pumped through the oil cooler. Other applications may have a system that is integrated with the jacket water system which is pumped through the oil cooler.
Transmission Oil Pressure (If Equipped) - Refer to the transmission "Operation and Maintenance Manual" for operating information and limits for lube oil temperatures and pressures. The transmission "Operation and Maintenance Manual" is provided by the OEM of the transmission.
Jacket Water Coolant Temperature - Typical temperature range is 87 to 98°C (189 to
