Engine Installation
Engine Installation Points
The systems for the engine that need to be connected are shown in Illustration 1 and 2. The systems must be connected to the vessel before operation of the engine.
 | |
| Illustration 1 | g00743293 |
The 3056 Marine engine is shown. (1) Exhaust systems (2) Electrical systems (3) Engine mounting (4) Starter cables (5) Fuel inlet (6) Stud for the zinc anode bonding system | |
 | |
| Illustration 2 | g00743294 |
The 3056 Marine engine is shown. (7) Refer to the Operation and Maintenance Manual, "Engine Lifting" for information on lifting the engine and the transmission. (8) Fuel return (9) Air inlet (10) Cooling system (11) Engine control | |
Installation Angles
 | |
| Illustration 3 | g00784642 |
3054 and 3054B Marine engines (1) The heel angle is 25 degree continuous and 35 degree intermittent. (2) The heel angle is 25 degree continuous and 35 degree intermittent. (3) Vertical installation (4) Acceptable heel angle | |
 | |
| Illustration 4 | g00784656 |
3056 Marine engine (3) Vertical installation (4) Acceptable heel angle (5) 30 degree maximum (6) 30 degree maximum | |
The marine engines are designed to be mounted so that the cylinders are vertical. The engine cylinders should be vertical when the engine cylinders are viewed from the rear of the vessel. On the 3054 and 3054B Marine engines, the heel angle is 25 degrees continuous and 35 degrees intermittent. Refer to Illustration 3. On the 3056 Marine engine, the maximum heel angle is 30 degrees. Refer to Illustration 4.
 | |
| Illustration 5 | g00784657 |
(7) The sea water should be at this level when the engine is installed in the vessel. (8) 3 degrees minimum (9) 17 degrees maximum | |
Mount the flywheel end of the engine in a downward position. The minimum is 3 degrees from the centerline of the crankshaft. The maximum is 17 degrees. Refer to Illustration 5.
 | |
| Illustration 6 | g00784658 |
3056 Marine engine (10) The sea water should be at this level when the engine is installed in the vessel. (11) The minimum angle is 3 degrees from the centerline of the crankshaft. (12) The maximum angle is 5 degrees from the centerline of the crankshaft. | |
If necessary, the 3056 marine engine may be installed with the flywheel end of the engine higher than the front of the engine. The maximum is 5 degrees from the centerline of the crankshaft. If the engine is installed with the flywheel end 5 degrees above the front of the engine, a new expansion tank must be installed. The new expansion tank should be higher than the flywheel end of the engine. Refer to your Caterpillar dealer for information on the expansion tank for this installation. Refer to Illustration 6.
