Check/service engine air cleaner of BELARUS-1021.3 tractors
Check condition of the paper filter elements (PFE) for paper break and correct installation
of the PFE. To check the basic filter element (BFE), proceed as follows:
- open the tractor hood to get access to the air cleaner;
- pull the yellow latch (1) (Figure 8.4.15), turn the cover (2) counterclockwise by 12.5° and
remove it;
- remove the basic filter element (3);
- check if there dirt in the master filter element (MFE) without removing it from its
housing.
- blow the filter element with compressed air first from inside, then from outside to
completely remove dust. To avoid a break of the paper blind, air pressure must not exceed 0.2 to
0.3 MPa. Direct the air jet at an angle to the filter element surface. During maintenance work,
protect the filter element from mechanical damages and contamination with oil.
Attention:
do not blow the BFE with exhaust gases or rinse in diesel fuel.
Attention:
removing the MFE from its housing is not recommended. Dirt in the MFE
indicates a failed BFE (break of the paper shutter, loose bond of the bottom). In such a case, rinse
the MFE and replace the BFE.
Clean the supply pipe, the inner surfaces of the casing and the cover of the air cleaner of
dust and dirt.
- check condition of the sealing rings;
- assemble the air cleaner in the reverse order;
- make sure that the BFE is correctly installed and close the latches (1);
- set the hood mask to its original position.

Attention:
untimely maintenance of air cleaner worsens air cleaning and leads to dust in
the engine, which causes increased wear of the cylinder-piston group and engine failure!
Attention:
after assembling the air cleaner, check tightness of all intake connections
(connecting pipes must not be broken or cracked, clamps must be securely tightened). If the check
reveals any faults or damages, find out their reason and take measures to eliminate them!
Attention:
in case of operation in high dust, perform the maintenance operation of
check/maintenance of engine air cleaner every 20 service hours of the tractor!
Operation 22. Check tire pressure
Check tire thread condition and air pressure. If necessary, bring the pressure to the required
in accordance with the load as specified in Table Standardsof loads on tires to choose the operation
mode at various internal pressures in 6.10 of 6 UNITIZING;
