3 Diesel engine installation and connection
3.1 Diesel engine hoisting
Incorrect hoisting will cause damage to diesel engine.
Fig. A
Fig. B
2 special cylinder-head bolts have been installed on each diesel engine, which are used for hoisting
diesel engine. A M14 threaded rod is mounted on the six-square end face of the two bolts, which is
used to mount the special slings (see fig. A) and lifting eyes. When using the special slings, screw
the suspender with M14 threaded hole onto two cylinder head bolts, adjust the center of gravity
and then it is good for hoisting. If the engine is hoisted through the lifting eyes attaching to the
cylinder head bolts, the slings as shown in fig. B is recommended. When hoisting the engine, its
crankshaft should be at horizontal level and two slings should at parallel status. Do not use one
sling which will lift the engine in the way of triangle. If you use one sling, the sling, cylinder head
bolts and lifting eyes are not at the same line. Therefore, this could cause damage to the bolts and
even fracture during hoisting, leading to damage to diesel engine.
3.2 Diesel engine installation
Apply the elastic coupler and ensure the crankshaft center line is concentric to the axis of the input
shaft of gearing equipments (gearbox, transmission). There should be no additive axial force on
the crankshaft caused by installation.
