Mamod steam loco - removing the bodywork and boiler

Undoing the two screws under the cab, and the buffers if fitted, allows the body to be lifted off the frames;


Again I've replaced the screws back into the frames so I don't lose them;


The boiler can then be slid back out of the body;


Disassembling the body is straightforward. By removing two screws in the cab frontsheet which sit either side of the boiler back plate the combustion chamber, which sits around the boiler, can be dropped out. Four more screws, two per side, hold the cab sides to the cab front aided by the handrails which also need to be removed;


I haven't mentioned the cab roof, simply because mine has already been unbolted, but it's just held in place with four screws. All parts are steel and cleaned up well just with handsoap and an old toothbrush.

Hindsight is a wonderful thing. Looking back, I think it would have been easier to remove the smokebox and body together rather than separately by undoing the two screws that sit behind the cylinders and screw into the smokebox casting, and the two that sit under the cab and attach the cab to the frames. Ho hum.

The next job will be to strip down the frames.

  1. It is struck me that this looks like a loco assembled from the kit, rather than a factory built example. I never did get mine to steam properly, I think because I hadn't lapped thecylinders. It languished for years before disapearing in a house move

    1. It is, something that I meant to mention above. This has made life easier as I haven't had to get the drill out, and as the sight glass cover is screwed in place rather than riveted it's also made cleaning the boiler out easier.

  2. What diameter are the axles please? Many years ago I saw a very neat battery electric conversion which may be a possibility for my example which has been languishing in the attic for 30 years....

    1. 4mm.
      A battery version sounds interesting, although you might get lynched by live steam purists!

    2. The Mamod was my first 16mm loco and it put me off live steam locos for ever! The one I'm thinking of was actually on a BigBig chassis rather than the original Mamod running gear.

    3. I can't imagine the weight of a Mamod body on a Big Big chassis would do the running gear any good!
      I know that Mamods have a certain reputation, but I'm curious to see just how well I can get mine running. And I haven't got the kind of money 'proper' live steam goes for.
