PENNSYLVANIA K-4 4-6-2
Lubrication
1. Oil all external moving parts of the
engine and tender with a high grade,
lightweight machine oil like 3-in-1.
Don’t forget the wheel bearings in
the pilot and trailing trucks, as well as
those in the tender. Dont’ over-oil; a
tiny drop will do the job.
2. Place the engine and tender on the
track and couple them together. The
drawbar between the units has tow
holes. For tighter curves, use the rear
hole. For wide-radius curves, the en-
gine and tender can be coupled more
closely together, using the front hole.
Then connect the water feed, fuel, and
water return lines.
3. The adjustable lubricator located
in the cab ensures the cylinders and
valves are properly lubricated inside.
As the steam passes through it, a
small amount will condense into water.
This water will sink to the bottom of the
lubricator, forcing a similar quantity of
oil into the steam line and thus to the
cylinders.
Remove the lubricator cap and draw
out any water from previous run with
a syringe. Use only proper steam cyl-
inder oil. Fill the lubricator, but leave
a small air space between the oil and
the cap.
4. Fill the front compartment of the ten-
der with water. Open the throttle valve
a little and pump water into the boiler.
Fill the boiler through its filler cap until
the water reaches the top of the glass.
This is BIG locomotive and it will take
a lot of water. Do not overfill the boiler;
there needs to be room above the wa-
ter for steam to form.
Use only distilled water in your en-
gine’s boiler. Tap water contains min-
erals that will leach out, cloud the
water glass, and ultimately affect per-
formance of the engine.
5. The fuel tank is located in the tender
Butane gas can be purchased at the
grocery store or at a tobacconist’s as
cigarette lighter refills. (Butane can
also be purchased more economically
in larger containers at camping sup-
ply store, but these cans will require a
special adaptor for filling the engine’s
tank.) Simply press the nozzle of the
butane canister hard onto the filler
valve at top of the tank, making sure
that the gas valve is closed
You will hear the gas transferring and
will see a little gas bleed out of the
valve. The gas may tend to sputter
a little from time to time while filling.
When the tank is full, the gas will be-
gin to sputter a lot and much more gas
will escape the valve. When the gas
tank is full you are ready to fire up the
engine.
