INSTALLATION GUIDELINES FOR ENGINES AND ACCESSORIES
3.1 De-preservation of new engine
After the engine packing crate is unpacked, carry out the pre-commissioning
inspection (PCI). Make sure engine and the sub parts supplied are as per the
purchase order, free from defects and all material supplied are as per the packing
list.
1. Wipe off the anti-rust coat, anti-corrosion agent, from the exposed parts such as
turbocharger, ywheel etc.
2. Drain preservation oil from the engine sump.
3. Inject sufcient lubricant to turbocharger lubrication line to ensure proper
lubrication during startup.
The preservation period of diesel engine is six months. When
the storage/ idle duration exceeds six months, conduct
inspection and adopt necessary supplementary measures as
per company recommendations.
3.2 Engine installation procedure
WP12 series marine diesel engine is assembled with SAE-I ywheel and ywheel
housing. Select the gear box and coupling accordingly. When installing the engine,
ensure the axial and radial alignment of engine crankshaft is linearly arranged with
the gear box input shaft. Dimensions from diesel engine-mounting bracket plane to
crankshaft centerline will be varying for different engine models. Fabricate / select
the correct base-frame according to the engine model (Refer gure 2.1 & 2.2).
It is advised to couple the diesel engine with gear box by using suitable elastic
coupling. After coupling the engine with gear box, no axial force is allowed to act
on the diesel engine crankshaft; otherwise it will lead to failure and damages of
engine’s major sub-assemblies.
