Drain tank
The position of the drain tank
is often in the double bottom.

Drain tank
Pumps draw the lubricant
from the drain tank.
From the cooler the lub oil
passes through the distribution-
branches in the engine.

In a crosshead engine oil bores run through
the crankshaft, crankwebs and crankpins,

The oil passes through the main lub-oil
supply line to the bearings.

In a trunk engine
the cylinder-lubrication
is done by the
oil mist
thrown up by the crank.

Used oil is passed through the
strainers (S) before it returns to the
drain tank.

Before the lubricating oil is entered
into the system again, it must be
purified by the strainer in the drain tank.

The oil-level is indicated with a level gauge
and is measured through a sounding pipe.
