1 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 fil-
ter (3). From here the oil, starting from the bypass
valve (4), is directed 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 () takes it
to the crankshaft to lubricate the roller bearing on
the crankpin; the other (7), whose flow is regulated
by a calibrated hole in the cylinder base gasket (8),
feeds the valvegear (9). The oil then returns to the
base of the crank chamber from the piston, the con-
rod assembly and the cylinder walls, and is drawn
in by the scavenge pump (10) through the mesh
filter (11). It is pumped through special jets (12)
and lubricates 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.
