LUBRICATION CIRCUIT
The output oil pump (1) draws in oil from
the area at the base of the gearbox through
its own mesh oil filter (2) and then sends it
to the paper oil filter (3). From here the oil,
starting from the bypass valve (4), is direc-
ted in three different directions: by means
of a jet (5) it lubricates the piston pin and
takes heat from the crown of the piston;
and it passes through two pipes, one of
which (6) takes it to the crankshaft to lubri-
cate the roller bearing on the crankpin; the
other (7), whose flow is regulated by a cali-
brated hole on the cylinder base gasket (8),
feeds the valvegear (9). The oil then returns
to the base of the crank chamber from the
piston, the conrod assembly and the cylin-
der walls, and is drawn in by the scavenge
pump (10) through the mesh filter (11). It is
pumped through special jets (12) and lubri-
cates the transmission gears. The oil in the
cylinder head, however, returns to the base
of the gearbox passing through the timing
case and the inner clutch casing.
