Making the Bachmann 4-6-0 run more smoothly

[Rhinochugger]

By popular demand - OK, one person asked - I will try and put my attempt to improve the Bachmann 4-6-0 in some sort of chronological order with the few photos that I have.

Let's address the elephant in the room:

The Bachmann Anniversary model, which is, I think, the fifth iteration of the 10-wheeler, must be the worst loco that I have ever had the please of trying to take apart. I now remember why I was a bit reticent to undertake this.

There is no logical assembly sequence, super-detailing bits have been added on without any logical thought for disassembly / re-assembly, and it is all too easy, as I found out, to damage bits if you try to dismantle things in the wrong way. For example, the front pair of footboards slide out of / into place once the four screws holding the body to the chassis at this location have been removed. the rear footboards can only be removed from the body, once the body has been successfully disentangled from the chassis and, therefore, have to be fixed back on before the body is offered up to the chassis . That's only one little thing.

So, why even try?

Well, the Slim Princess is based on an Annie chassis, and has always stuttered from time to time. It'll run OK for one or two laps of the garden, then it will start to stutter. On the other hand, the Centennial 4-4-0 will run smoothly all afternoon. Why does the 4-4-0 run better than the 4-6-0?

 

[Rhinochugger]

I made some home-made current collectors for the bogies on the tender, and this seemed to help for a while, but after some less than satisfactory running earlier this year, I bought a couple of tender bogies from Bachmann USA which are intended for the Mining Mogul, and which have ready made current collection with suitable wheels.

However, I have long complained about Bachmann's failure to use flywheel mechanisms. They're of no benefit to DCC users, nor for battery power, but for track power they are de riguer in the smaller scales, so why not include them in the larger scale designed for outside use where current collection is as much of, if not more than, an issue.

Dismantling

I don;t intend to list every screw and piece to be removed, because I'd inevitably get it wrong, but after removing the cab, and then undoing anything is sight, you will eventually end up with a chassis and boiler which have a number of wires keeping them joined. Having removed the base plate from the chassis, you can locate two screws (one either side) which are basically connector terminals. There are only two colours of wire - red and black - so it's safe to undo these and let go. You will also need to pull the small pins off the long brass current collector strips, and this will allow the body to be free.

Even with the wires removed, the motor is a close enough fit in its original location, so there;s no chance of getting a flywheel on it in its current position.

You will also need a double shaft motor, so we need to get the rear axle out; this requires removal of the hexagonal crank pins on the rear and centre axles - no more valve gear dismantling is necessary.

The gear box has a long, locating pin through it that goes right through the chassis, and this needs removing. I used a large clamp with a 40mm nail and, by serendipity, pushed it out the correct way - it is only knurled on one end, and from memory that is the right hand side, so push from the left. I rested the jaw of the clamp on the chassis side, clear of the pin, and it popped out easily.

Next remove the wheels ................... next time.
