by the pump through acontrol valve to the filter, the enginemain bearings and, by way of external pipelines, to the rocker arms.
Also, read the heading 9.2.
Oil circuit pressure (with hot engine):
min / 800 rpm = 1.5 kg/cm
2
(21.3 psi / 147 kPa)
máx / 3000-3600 rpm = 3-5 kg/cm
2
(43-71 psi / 294-490 kPa)
(1) without change oil filter (only change oil)
