Lubrication - roundhouse WILLIAM Owner's Handbook Manual

There has to be a space above the water to allow steam to be raised so, insert
the end of the plastic pipe into the boiler and withdraw 30ml of water with the
syringe. Replace the filler plug finger tight.

3) LUBRICATION

Regular lubrication of all working parts is important and should be carried out
before each operating session. There are two types of lubrication required:
The external moving linkages and bearings are lubricated with a medium oil
such as motor engine oil, and the internal steam mechanisms such as cylin-
ders, pistons and valves are lubricated with a special steam oil that is mixed
with the steam. Infrequent external lubrication will allow parts to run dry, and
over oiling can form pools around operating parts that attract dirt and grit. If
too thin an oil is used it will evaporate very quickly as the loco gets hot –
leading to dry running. We recommend the use of a 20-50 motor oil for exter-
nal lubrication.
Internal lubrication is achieved by steam oil that is mixed with the steam in
the displacement lubricator, housed in the left-hand side of the cab. Remove
the knurled cap from the top and slacken the drain screw two or three turns at
the bottom but do not remove it. Any water in the lubricator will run out
through the drain screw. Tighten the drain screw and refill with the steam oil
supplied, then replace the cap. Take time filling the lubricator, especially
when cold, as the oil takes time to run down and may trap an air bubble. Both
cap and drain screw are fitted with '0' rings and need only be closed finger
tight.
NOTE: Only special steam oil as supplied should be used in the lubricator
and under no circumstances should ordinary oil be substituted, or damage may
result.

The gas and steam regulators will require periodic lubrication see the
troubleshooting section for details.
