In case of excessive clogging of filter
paper, when oil filter resistance exceed
0,13...0,17 MPa, the oil filter overflow valve
also opens and oil comes to the oil pipeline,
bypassing the oil filter.
The plug of the reducing valve
must not be turned off at the operating
diesel engine.
Oil is delivered from the main pipeline
of the diesel engine through passageways
in the cylinder block to all crankshaft main
bearings and camshaft necks. Then oil
comes from main bearings through pas-
sageways in the crankshaft to all rod bear-
ings. Oil is delivered from the first main
bearing trough the special passageways to
the intermediate gear bushings and fuel
pump drive gear and the fuel pump.
The parts of the valve mechanism
are lubricated with oil, which comes from
the rear bearing of the camshaft through
the passageways in the block, cylinder
head, drilled hole in the IV. rocking arm
shank to the body cavity of the rocking
arm axle and through the opening to the
rocking arm bushing from which it comes
to the adjusting screw and barbell.
Oil is delivered to the compressor
from the main pipeline through the drilled
holes in the cylinder block and special oil
pipeline. From the compressor oil is
drained to the diesel engine crankcase.
Oil comes to the bearing unit of the
turbocharger through the pipe at the oil
filter housing outlet. From the bearing unit
of the turbocharger oil is delivered through
the pipe to the oil crankcase.
