PTO and prop shaft drive alignment
Drive couplings
See the ‘Ancillaries’ (section 3.8-torque coupling) for recomendations on
couplings for PTO drives.
Before fitting, the tapers on the machine shaft and drive coupling should be
clean and damage free to help ensure the flange fits correctly. Both tapers
should be smeared with a light oil to aid future separation.
The companion flange should be fitted 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 flange or shaft end.
