– Oil pressure gauge in GB
The oil pressure in the GB hydraulic system at the transmissions with the crankshaft rotation
speed of 900
–1,800 RPM shall be as follows:
1.0
–1.2 MPa (10–12 kgf/cm
2
)
– for K-744R1, K-744R2 tractors;
1.1
–1.3 MPa (11–13 kg/cm
2
)
– for K-744R3, K-744R4 tractors.
The oil pressure growth on each transmission shall be fast. The pressure on neutraland in
engagement of synchroniser brake shall not be less than on transmission gears.
In case of pressure fall in GB below 10 kgf/cm
2
for K-744R1, K-744R2 tractor and below
11 kgf/cm
2
for K-744R3, K-744R4 tractors, a sound alarm will get operated in the intermittent
mode 30 s later.
On K-744R4St tractor, it is allowed to admit movement of the GB oil pressure pointer to the
beginning of the
“red” zone on the right at the maximum rotational speed of the crankshaft and
the GB lever set in the neutral position.
* It is allowed to switch on the indicator lamp of clogging of the pressure filter of the hydraulic system of steering control
for a short period of time until the operating oil temperature of the hydraulic system reached ~40
–50°С.
