PTO and prop. shaft drive alignment.
Changing the machine rotation
The current direction of input rotation is indicated by cast arrows on the
compressor body. Changing rotation is a simple process of swapping over
the plastic cowls, key & drive flange as shown in the diagram below.

Figure 6. Drive Flange Removal
Fitting the drive flange
Standard drive flanges (and fasteners) are supplied with all new packages to
fit either end of the rotor shaft.
Before fitting, the shaft and flange should be clean and damage free to
ensure it fits correctly.
Both the shaft and coupling bore should be smeared with a light oil during
assembly to aid future separation.
A Hollow Set Screw (Grub Screw) should be used for retaining the drive
flange, in position on the shaft.
Apply Loctite 270 to the Grub Screw and tighten to a torque of 7.2Nm.
A puller type device will be required to remove the flange (see Fig. 6) to help
avoid damaging the shaft or flange.

Figure 5. Changing Rotation
The machine rotor must
always rotate in the same
direction, but the opposite
input drive rotation can be
achieved by driving the rotor
from the other end of the
machine.
