8 – Axle pump fails to
maintain water level
8.1 – Gland leaking
Tighten or re-pack the gland
8.2 – Balls valves in pump
sticking or leaking
Remove and clean balls and seats.
Replace balls if necessary
8.3 – Pump fitted upside down
Fit correctly with the inlet at the
bottom
8.4 – Pipes blocked
Blow through to clear. Check the
pump. Remove the top union,
cover the outlet with a finger, push
the loco to work the pump. Water
should overcome finger pressure.
Balls in the pump and non-return
valve can be heard ‘clacking’ when
the pump is operating
9 – Hand pump failure
9.1 - Balls stuck or leaking
Remove and clean ball and seats
(try hot water in the tanks before
removing the pump)
9.2 - Pipework or unions
leaking
See Problem 5.
PROBLEM
CAUSE
CURE
10- Injector failure
10.1 – Air leaks in the system
Ensure that rubber pipe
connections and glands are tight
10.2 – Blockage in injector
Check that there is a pinhole
through the body. If not soak in
vinegar and blow through to clear.
DO NOT attempt to clear a blocked
injector with a wire or pin. Return to
makers for testing.
10.3 – Water/injector too hot
Re-fill tanks with cold water. Cool
injector
11 – Lubricator failure
(mechanical)
There should always be oil
or oily soot around the top of
the chimney. Squeaks and
stiffness in the cylinders
indicates lubricator failure.
11.1 – Rachet does not move
forward one notch
Check for lost movement on
linkage. Raise the drive arm up the
lubricator arm to increase
movement
11.2 – Rachet wheel sticks
Damage to ratchet wheel or pawl.
Repair or return to manufacturer
11.3 – No oil feed
Check for blocked or leaking pump,
pipework or non-return valve.
Check the lubricator. Remove the
oil feed pipe, cover outlet with
finger. Turn the ratchet wheel to
work the pump. Oil should
overcome finger pressure. If oil still
fails to reach the cylinders, check
non-return valve for too strong
spring tension or sticking
