Operation 38. Clean engine air cleaner
•
Remove the monocyclone (7), clear the
mesh, swirler and ejection slots from
dust and dirt.
•
Unscrew the butterfly nut (2) and
remove the pan (1);
•
Remove the basic filter element (5).
Pay attention to the condition of the monitor
filter element (4).
ATTENTION!
Pollution of the KFE
indicates a damaged BFE (the paper
shutter broken, the bottoms unstuck).
Note:
Taking out the MFE (4) from the
casing (6) is not recommended.
If the BFE has no damage, blow it with
compressed air first from inside, then
outside to completely remove dust.
ATTENTION!
To avoid a break of the
paper shutter, air pressure must not
exceed 0.2 to 0.3 MPa.
Direct the air jet at an angle to the BFE
surface. Avoid contamination with oil or
mechanical damage to the BFE.
•
If blowing with air is inefficient, rinse the
BFE in washing solution. The
concentration of solution is 0.02%. To
wash the BFE, dip it in the washing
solution for 0.5 hours, then rinse
extensively in this solution for 15 min.
Rinse the BFE in pure water at 35 to 45°C
and dry for 24 hours.
ATTENTION!
Do not blow the BFE with
exhaust gases and do not rinse it in
diesel fuel.
•
Clean the exhaust pipe, inner surfaces
of the housing and air pan from dust and
dirt.
•
Check condition of the sealing rings.
•
Make sure that the BFE is correctly
installed in the housing and tighten the
butterfly nut by hand.
•
Perform the Operation 24 to check
tightness of the air cleaner and intake.
