Centrifugal Oil Filter; Removal; Inspection - Honda CB350 Repair Manual

All Honda 350/360 models are of the
wet sump—type. This means that the oil
supply is contained in the crankcase
sump rather than in an 'external oil tank.
The 350 models have a plunger—type
pump driven from the clutch housing by
way of a connecting rod. The 360 models
use a trochoid—type pump driven off the
primary gear by way of an idler gear.
Before entering the pump, the oil passes
through an oil filter screen to remove any
large particles. The oil is further filtered
through a centrifugal oil filter before
being pumped under pressure to the cyl—
inder head, crankshaft assembly, and
transmission shafts.
