Adjustment of the belt for the pump drive-
Fig.15a, 15b
Tightening of the belt for the pump drive is performed by the
shift of the complete pump (position “1”) in the grooves of the
pump consoles.
Fig.15a
Procedure:
1. Loosen 4 securing bolts of the pump (position “3”) so
the pump can freely move at the ends.
2. By symmetric pushing of the pump from the frame by
means of two pressing bolts (position “2”), tighten
the belt. Proceed according to Fig.15b and the
Table. (Note: A low tightening force may cause
skipping of the belt pulley teeth in the case of large
loads)
3. In the correct position, 4 securing bolts of the pump
are tightened.

Adjustment of brakes– Fig.15c
1. Adjustment of air brake valve
The adjustment of the brake valve is based on the
adjustment of the clearance between the brake plates and
the disk of the brake. It is adjusted with the released
terminal of the draw bar of the brake when the joining
spring does not produce any force on the level of the air
brake valve. The clearance is decreased by screwing the
pocket of the axis into the body of the air brake valve. (On
the contrary, during the unscrewing it is increased). The
correct clearance is achieved at the angle of the deviation
of the lever of the air brake valve from the neutral position
to the contact of the brake plates on the disk within the
range 15-20
o
.
2. Adjustment of the draw bar of the brake:
After the adjustment of the air brake valve, there is the
adjustment of the draw bar of the brake by the relocation
of the terminal on the draw bar and its securing by the nuts
in such a position where the join spring is tensioned and
slightly “wheezes” in the holes of the lever and the
converter.
