TROUBLE SHOOTING & MAINTENANCE
On a working model of this nature, it is important to keep all
working parts well lubricated. With constant heating up, cooling
down and the stresses of hard work, screws etc. can work loose
so, it is good practice to check all fixings and cylinder screws
regularly but remember, never over tighten.
STEAM LEAKS
The cylinders are fitted with 'O' rings in the glands sealing both
piston and valve rods. These can be adjusted if steam leaks
develop. They should only be tightened just enough to stop the
leak, as over tightening will affect the running of the model.
Cylinder covers are fitted with gaskets and valve chests with ’O’
rings. A little ‘bubbling’ of oil may sometimes occur around these
and is quite normal; however, steam leaking past the gasket should
be attended to.
If ‘nipping up’ the retaining screws does not stop a steam leak, a
service kit is available which includes replacement gaskets and
seals and full instructions for fitting. Valve chest screws can only be
accessed by removal of the power bogie from the locomotive.
REGULATOR NOT SHUTTING
The steam regulator seating and seal can, after a period of time
become worn or compressed so that when the lever on the radio
control is fully closed, the locomotive still moves. To overcome this,
a trimmer is fitted to the transmitter. As wear takes place in the
regulator, it can gradually be adjusted to compensate. When no
more adjustment is possible, it is time to reset the trimmer and
adjust the linkage between the servo and the regulator in the cab.
If adjustment does not cure this problem, the internal '0' ring is
probably damaged and requires replacement. Contact the factory
for further advice.
Periodic oiling of the gland will help keep the regulator working
