Default King Charles rebuild

OK for my next trick I'm going to see if I can resurrect this old Lima crate. I rather like it in blue

Doesn't run although the bloke who sold it to me reckoned it did grrrr

OK first question. Where does this part go. It fell out when I opened it up and I didn't see where it came from (yeah I know rookie error )

That part clips on top of chassis just ahead of the cylinders. There are bright metal parts sticking out of front of cylinders (valve rods) and they sit in the flat ends of the valve linkage in front of cylinders.
REF This part = valve linkage.

There is no reason why it will not work it is just a simple Ringfield motor. Just make sure that all the wires are soldered on correctly and the brushes and springs are all OK . Try testing the motor with wires from a controller set at about 1/3 speed to start with. Touch the wires one on each brush holder and the motor should work.

OK next question, I'm making on with this today, the bodies are washed and primed and waiting for paint. The motor has been overhauled and runs very nicely...HOWEVER...

Look at these pics. If I put a croc clip from my test transformer onto point A and then the other at point B it runs beautifully.

If I then move my croc clip to point C (the axle) it runs

Point D (the copper strip underneath) it runs

Point E (the axle stub) it runs.

Point F the wheel rim it does NOT run. A multimeter is telling me there's no continuity between wheel rim and axle. How can this be? There is continuity between different parts of the wheel rim. Do I have a wheel with a plastic middle bit?? (Notwithstanding the fact that it was sold to me as a runner!)

Looking carefully at the wheels you might notice that they have counterweights and holes where a con rod may have once been placed. Unlikely on a tender? Are they the wrong wheels?

That’s because the wheel rim is insulated from the axle. It also has a tyre on it. The wheel on the other axle on the same side as F should also be insulated and is missing a tyre you can see it has a groove to take one. On that loco the power to the motor was from one side of the tender and the other side on the loco. Some picked up from both sides of the loco but always only one side of the tender.

Hope I’ve not given you duff gen, it’s been a long time since I’ve owned one.

The reason it fell out was the body holds it in place.
