Maintenance – Section 5.3 - Assembly Procedure
Pump Assembly – Fluid Section / Air Motor
1. Fit plug (68) and seal (77) to inlet cylinders (80)
2. Mount inlet cylinders (80) onto end plates and over each shaft and bellows. Secure
loosely with lightly greased 4off M14x40 cap head screws (65) and 4off Ø14 washers
(63).
Do not tighten at this stage as this may lead to bellows damage when assembling
the piston to the shaft.
3. Apply Loctite 243 to the piston shaft threads
and screw the piston assemblies onto shafts,
tighten up to 50 Nm. Note: If both fluid sections
are being assembled tighten by holding one
piston with its 14mm hexagon socket and
torque the other piston using its socket.
4. Lightly grease with type # the pistons and fit
the piston seals (77), wear lip pointing away
from the shaft thread.
5. Fit outlet cylinder sub-assembly over the seal,
secure with lightly greased 4off M14x40
caphead screws (65) and assemble with 4off
Ø14 washers (63) to hold the cylinders
together. Tighten evenly all the cap head screws to 50Nm.
6. Tighten the caphead screws holding the inlet cylinder to the air motor to 50Nm
7. Mount inlet (93) and outlet (94) manifold to the fluid sections using clamps (92) and
seals (91) to orientation required.
8. Install mufflers (90) into exhaust adapter. Alternatively hose fitting (192802) and 1” plug
(192803) can be fitted where piped exhaust is required.
