5.4.5.1 General instructions
Perform the previous operations, as well as the operations listed in this subsection
5.4.5.
5.4.5.2 Operation 45. Changing oil in the HLL and HSC conjoint tank, washing the filter
cartridge of the breather of the HLL and HSC tank
Before changing the oil, start the engine briefly for 2 ... 3 minutes to stir oil in the tank.
To speed up the draining of oil from the tank in the cold season, it is recommended to perform
an accelerated warm-up of the oil. To do this, with the engine running, set any of the hydraulic
output control levers to the “raising” position and hold the lever in this position until the hydrau-
lic system heats up.
To change the oil in the HLL and HSC tank, do the following:
- place the tractor on a level ground, set the RLL links to the lowest position, apply the
parking brake; the engine must be turned off;
- unscrew oil filler plug 1 (figure 5.4.44) and drain plug 4, drain oil from oil tank 3 into a
special container for used oil;
- put back and tighten drain plug 4, fill the system with fresh oil up to the required “П”
mark on oil level indicator 2. When using machines that require large oil takeoff, fill in the oil to
the level corresponding to the upper mark “C”.
- put in place and tighten oil filler plug 1.
1 - oil filler plug; 2 - oil level indicator; 3 – HLL and HSC oil tank; 4 - drain plug.
Figure 5.4.44 - Changing oil in the HLL tank
ATTENTION: THE OPERATION OF OIL CHANGE IN THE TANK OF THE HYDRAU-
LIC LIFT LINKAGE SHOULD BE PERFORMED ONLY WHEN THE RODS OF THE RLL HY-
DRAULIC CYLINDERS AS WELL AS THOSE OF THE MACHINES ATTACHED TO THE
TRACTOR ARE RETRACTED!
WARNING: BE CAREFUL TO AVOID CONTACT WITH HOT OIL AND HOT OIL TANK
SURFACE!
Simultaneously with oil change in the HLL and HSC tank, it is necessary to wash the fil-
ter cartridge of the breather of the HLL and HSC tank.
The breather is located on top of the HLL and HSC conjoint oil tank.
To flush the breather filter cartridge, do the following:
- clean the location of the breather on the HLL and HSC oil tank 4 (figure 5.4.45);
- disassemble the breather, for which unscrew plug 2, remove washers 1 and filter 3.
- wash the listed parts in clean diesel fuel;
- blow out the plug and washers, squeeze and dry the filter;
- put the parts in place, tighten the plug with a torque of 25 to 35 Nm.
