To discharge the accumulated oil, baff,Jed by the flywheel gland,
the crankcase is provided with oil-drain passage 1.
To prevent the oil leakage from the crankcase to the clutch, the
flywheel hub is fitted with a rubber gland; the breaker is protected
against oil contami nation by means of a rubber gland on the cam -
shaft.
The centrifuge is used as a s· econdary oil fil~er. Before reaching
the centrifuge, the oil is cleaned by passing only through the gauze
of the oil header. Aluminium body 8 (Fig. 11) and centrifuge cover
