5 MAJOR SERVICING
5.1 Air Pump Maintenance
5.1.1 Delivery and Suction Valves (A07)
Failure of the pump set to prime quickly or to discharge
the expected volume of air, may simply be due to faulty
valve operation.
To inspect and service, proceed as follows:
1. Remove air hose (single prime item (A01), twin
prime items (A39/40)) from suction valve box
(A03/A41), after loosening relevant hose clips
(A02).
2. Note the orientation of the suction valve box (A03)
and exhaust cover (A04) before commencing.
Remove exhaust cover (A04) and suction valve
box (A03) by releasing nuts (A05) and spring
washers (A06).
NOTE: The above actions allow the condition of the
two valve rubbers (A07) to be checked. Do NOT
attempt to remove valve studs (A08). If valve rubbers
are damaged, replace with new components. Pull old
valves off stud heads, and discard.
3. Check and, if necessary, clean valve seats in
outer pump body (A15) and valve box (A03).
Smear heads and grooves of studs with soft soap
and push on new valves ensuring that they seat
correctly.
4. The valve assemblies can now be replaced by
reversing Instructions 1 and 2 of this procedure. It
is advisable to fit new gaskets (A30).
5.1.2 Actuator Valve (A16)
Another reason for the pump set failing to prime
efficiently or to handle the expected volume of air,
could be malfunction of the actuator valve (A16).
To inspect and service, proceed as follows:
1. Remove nuts (A11), spring washers (A12),
washers (A13) and screws (A14), allowing outer
pump body (A15) to be removed complete with
attached delivery valve assembly. The actuator
valve (A16) may now be examined. If it fails to
seat efficiently on actuator (A20) or is in any way
damaged, it should be pulled off the actuator nut
and discarded.
2. Whilst the actuator valve (A16) is removed, it is
advisable to examine the condition of the valve
seat in the actuator (A20), and also to check the
security of the actuator screw (D36). This should
be checked and tightened to 60lbf ft (8.3kgf m)
torque.
3. To replace actuator valve (A16):
a) Smear soft soap on the conical end and
groove of actuator screw (D36).
b) Ease new valve rubber into position ensuring
that it seats correctly.
NOTE: It is advisable to examine the condition of
actuator seal (A18) whilst it is exposed. Refer to
Section 5.1.3 Actuator Seal (A18) for servicing
instructions.
4. To replace outer pump body assembly, fit and
evenly tighten screws (A14), washers (A13),
spring washers (A12) and nuts (A11), by
sequentially turning each screw a small amount
until they are all fully tensioned.
NOTE: It is important that the outer diameter of the
actuator seal (A18) should be evenly clamped.
5.1.3 Actuator Seal (A18)
A further reason for the pump set failing to prime
efficiently or to handle the expected volume of air,
could be a faulty actuator seal (A18).
To inspect and service, proceed as follows:
1. Remove outer pump body (A15) complete with
delivery valve assembly. Remove actuator screw
(D36).
