Pneumatic Compressor
To ensure reliable operation of the trac-
tor pneumatic system and tyre inflation,
the engine is equipped with a single-
piston, single-stage compressor. When
performing the agricultural works which
do not require the energy of com-
pressed air, the compressor shall be
turned OFF.
The compressor is mounted on the fuel
distribution unit cover flange and driven
from the fuel-pump drive gear. The
compressor is air-cooled. When the
compressor is running, the fan shall be
switched to the forced mode.
The compressor delivery is 180 l/min at a
backpressure of 0.6 MPa (6 kgf/cm
2
) and
the rated rotational speed.
NOTE:
With the compressor running,
the engine fan shall be switched to the
forced mode.
