- indicator of oil pressure in GB
Oil pressure in the GB hydraulic system at gears with the crankshaft
rotation rate of 900-1800 RPM shall be:
1.0 - 1.2 MPa (10 - 12 kgf/cm
2
) - for K-744R1, K-744R2 trac-
tors;-
1.1 - 1.3 MPa (11 - 13 kgf/cm
2
) - for K-744R3, K--744R4 trac-
tors.
Oil pressure growth at each gear shall be rapid. The pressure on
neutral gear and at engagement of synchroniser brakes shall not be
less than on transmission gears.
Upon pressure fall in the hydraulic system below 10 kgf/cm
2
for
at least 30 s, indicator starts blinking and the instrument panel
provides an intermittent sound signal on low pressure in GB.
When a buzzer sounds in the course of operations, they shall be
stopped; using mechanical pressure gauge, make sure that the
pressure in GB corresponds to the operating pressure.
