Alignment
The D900 input drive and the vehicle Power Take Off (PTO) should be parallel within
1 degree and positioned such that the linking drive shaft makes an angle of no greater than
12 degrees.
Note: Refer to PTO manufacturers literature when installing.

Belt Drive.
The D9000 unit is designed to be belt driven from the vehicle PTO. A belt drive unit suitable
for the installation and capable of transmitting the required power can be ordered via your
Drum dealer. Figure 6 shows the components of a typical Drum belt drive unit. The belt drive
can be fitted to either of the two shafts on D9000 but the direction of rotation of the D9000 unit
must be maintained
(see section 2.3).
When ordering the belt drive the following information will be required:-
•
The centre distance between the D9000 driven shaft and the PTO driver shaft.
•
The angle of inclination of the belt drive to the horizontal.
•
Required step-up ratio (standard is 1.78 : 1).
Belt Drive Installation.
The Belt Arm Assembly must be fitted
AFTER
the D9000 unit has been fitted to the chassis
and not whilst the Compressor is on its delivery pallet. The pallet is not designed to allow the
lifting of both Compressor and Belt Arm Assembly.
Assemble the inner Arm (1), Outer Arm (2), Outer Bearing Housing (3), and spacer (7) onto
the D9000 compressor at the required side and angle of inclination. (Refer Fig 6, Page 8).
Note: The driver pulley is factory fitted in a mid position and may need adjustment when
checking the alignment of the pulleys.
Fit Driven Pulley onto D9000 Drive Shaft using Shaft Key. Position pulley to acheive the best
possible taper lock, and lock onto the drive shaft using the stud, securing nut and washer.
Loosen M10 setscrews (4
)
clamping the outer arm to the inner arm, slide the outer arm so the
centre distance between the compressor and the bearing housing shafts is at a minimum.
Re-tighten any two of the setscrews to hold this position.
Flange faces to be parallel within 1°
