GD150 Installation, Operating & Maintenance Manual
Installation
3.7
Machine and PTO Alignment
The drive axis on the majority of PTO’s is at 3 - 5° to the horizontal, which
reflects the angle of the engine and gearbox.
The compressor should be mounted so that its drive axis is parallel to the
PTO’s drive axis (within 1 degree) - see fig 7 .
The compressor should also be mounted so that the prop. shaft angle
between the PTO and GD150 in any plane (including compound angles) is
less than or equal to 12°.
Consideration should be given to the prop. shaft length when mounting the
machine and the prop. shaft should be sized so that it always has sliding
clearance.
Also check the prop shaft
manufacturers information for
the permitted installed angle.

3.8 Pipe work
- Figures 1 & 8 show typical pipe work layouts
Standard inlet
A flexible inlet pipe, inlet filter, machine inlet flange and gasket are all
provided in the inlet induction kit.
Fabricated pipework
Where any pipe work is to be fabricated, the following points should be
followed/noted to prevent damage to the machine:
• A stainless steel slip-on-weld flanges provided with the machine
for use with 1.5” nominal bore pipe work.
• Inlet pipe work should be made in stainless steel or thick wall aluminium to
help prevent corroded particles entering the machine.
• Outlet pipe work can fabricated from any material (including mild steel) to
suit the application, although stainless steel is recommended.
• All fabricated pipe work should be carefully de-scaled/cleaned before
commissioning the compressor.
• Pipe work should be attached to the vehicle chassis using flexible
mountings to prevent unnecessary vibration, expansion stress, noise
transfer and avoid distorting the machine body.
• A flexible element is recommended in the discharge pipe work (and inlet
pipe work when necessary) to absorb any pipework distortion created
through chassis movement and heat expansion.
• All inlet and discharge pipe work should be as free from bends as
possible to minimise pressure drops. This allows the machine to work in
the best inlet conditions and provide the maximum discharge pressure.

Note: The combined angle in any plane
should not exceed 12˚
