Stainz 20212 Direct Decoder Interface

[Mike Bett]

Can anyone tell me where the interface is and the easiest way to get to it?
I wish to fit a 55021 chip, preferably without taking out ebery screw!!!

Hi Mike, I think the board for that loco is on top of the weight in the boiler barrel. Its a total strip down.
From memory. remove the ploughs front and rear
Remove screws that hold chassis to body (not the gearbox cover screws.)
Unscrwe the chimney base nut. Two small screws hold the motion to two black brackets under the frames - remove these.
Ease chassis from bodywork - the motion needs releasing through the body work.
Unscrew one small screw on air pump moulding and unclip filler funnel at lower end.
Separate boiler halves.
Decoder interface is on top of the existing board.
Reverse.
For a basic loco - its a bugger.

Your right Chas. A bugger to dismantle but a battleship construction.

Anyone who says a German has no sense of humour should take a Stainz apart.

Thanks Paul - I have copied that link into the decoder list for future reference.

This might help you Mike :

I've dismantled one or two................

I have no problem dismantling them but keep asking
Why does the bloke in the cab grip the side like hell when you are trying to get it apart?
Why do you have to dismantle it a second time to replace the 2 weights that are always left over?
Why do you have to dismantle the loco into its component parts just to add a decoder?
Obviously designed by a bloke with a warped sense of humour!

Your quite right, he does. Pain in the backside until he unglues himself.

Thanks everyone, the links are more than one could hope for. Jeremy has posted the chip, the snow is falling, so will have bags of time to give it a go.
If I make a coblers of it and if the snow has gone, I will take up Alan's kind offer of help
I have chipped a couple of locos which do not have interfaces (V. old models) so hopefully all will be well.

I am still trying to get my avatar into that frame - just testing to see if I have managed it!!

When you take a Stainz to bits it becomes apparent just what a brilliant design it is (especially since its the starter set loco). Its certainly the most intricate lok I've ever dismantled.

A design masterclass

Actually the combination of high complexity and starter set means it's an outstandingly BAD piece of design, speaking from a production engineering viewpoint. The cheaper the item, the more basic you want the design to be. Piko are proving themselves brilliant engineers in that respect. Intricacy = cost = lower profit.

That said, the Stainz is a charming loco and I wouldn't be without my two!

Well some times you get lucky. Having opened the Stainz which I purchased as without a chip. I found changed wiring as in the attached photo. It looked like a chip had been inserted - but in a strange way. I checked it out with the computer interface, which confirms that a 55021 has been fitted and programmed correctly ( I have changed the loco number now).

I would have attached a picture if I could work out how to do it!!!!!!!!!
The black interface plug is there but is not attached, however the four wires that come from the chip have been plugged into the motor block.

The picture thing defeats me - I have tried in vain to get a picture into the frame, no joy, help.
