– 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 kgf/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.
14
– The air pressure gauge in the first circuit of the pneumatic system with built-in alarm
signaling of the minimum limit value of 0.45 MPa (4.5 kgf/cm
2
)
The air pressure in the pneumatic system in the process of operation shall be equal to 0.65
–
0.8 MPa (6.5
–8 kgf/cm
2
).
*
** 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.
