important that no obstructive structures are built next to engine driven pumps, as well as
camshaft and crankcase doors.
However, also at locations where no space is required for dismounting of engine parts, a
minimum of 1000 mm free space is recommended for maintenance operations everywhere
around the engine.
18.2.2 Engine room height and lifting equipment
The required engine room height is determined by the transportation routes for engine parts.
If there is sufficient space in transverse and longitudinal direction, there is no need to transport
engine parts over the rocker arm covers or over the exhaust pipe and in such case the
necessary height is minimized.
Separate lifting arrangements are usually required for overhaul of the turbocharger since the
crane travel is limited by the exhaust pipe. A chain block on a rail located over the turbocharger
axis is recommended.
