Figure 7b. DIN Friction Coupling
Installation
3.5 PTO and prop. shaft drive alignment
Shaft cover
The compressor can be driven from either end of the input shaft (see section
3.3 for further details of the orienations possible).
The clockwise end of the compressor input shaft is protected with a shaft
cover. If this shaft is required, remove the cover and refi t it over the unused
shaft at the opposite end of the machine.
Drive couplings
See the ‘Ancillaries’ (section 3.8-torque coupling) for recomendations on
couplings for PTO drives.
Before fi tting, the tapers on the machine shaft and drive coupling should be
clean and damage free to help ensure the fl ange fi ts correctly. Both tapers
should be smeared with a light oil to aid future separation.
The companion fl ange should be fi tted to the compressor shaft in line with
Figure 7b, for the DIN type coupling and Figure 7c for the SAE type coupling.
The cap screw and washer which is used to retain the coupling to the shaft,
should be tightened to a torque of 88Nm.
Flange/coupling removal should only be undertaken with the aid of a puller
type device and screw in the shaft end, as shown in Figure 7a, to avoid
damaging the fl ange or shaft end.

Cap Screw (Item 5) should be
tightened to a torque of 88Nm.
