MAINTENANCE TO BE PERFORMED AS REQUIRED
Procedure 60. Adjusting the Oil Pres-
sure in the Engine Lubrication System
If the oil pressure in the lubrication sys-
tem is below 0.28 MPa on a warmed-up
engine and at the rated speed of the
crankshaft, stop the engine, locate and
remove the trouble. Check the oil pipe-
lines for leak-tightness and the safety
valve of the oil paper filter for operability.
One of the ways for increasing the pres-
sure is slight adjustment of the filter at a
specialized workshop.
Procedure 61. Adjusting the Gear-Box
Centrifugal Oil Filter
The valve (2) maintains oil pressure on
the GB hydraulic system to within
0.9...1.0 MPa – for the GB 16Fx8R;
0.9…1.1 MPa – for the 24Fx12R.
If pressure drops below this limit, adjust
the valve by inserting additional shims
(5) between the spring (3) and the plug
(6).
IMPORTANT! If the pressure drops
below 0.7 MPa, stop the tractor and
seek help of a technician.
The valve (7) maintains oil pressure up-
stream of the centrifuge rotor. It shall be
0.75 MPa and can be adjusted, if re-
quired, by inserting the shims (9).
The lubrication valve (12) is adjusted to
within 0.15...0.25 MPa and maintains oil
pressure in the GB lubrication system.
The valve is adjusted by insertion of
shims (11).
