I have one of these lovely (and useful) locos, but yesterday the motor died. I have done all the checks I can think of, i.e. continuity across the commutator, cleaned the brushes, but it appears only one segment is ok. Terminal isn't it? So can I get a replacement motor, with or without the worm?
It's an old model and I see on the web I can get a new loco complete for about 50 notes, but being a sentimental old chap, I would like to get it going again. Can anyone help please, sell me one or point me in the right direction?

Tod,
On ebay Sven van der Hart of Tramfabriek offers a coreless motor conversion for
Thanks for that. I will have search later after a dental hygenist appointment this morning. Nice girl, but not the slightest interest in model railways, I wonder why?!!!

There are several versions of the Roco diesel loco chassis over the years.
I think the conversion is only for the more recent versions with the gearbox at the front and a spring drive.
The earlier versions had no spring drive and the worm on the motor shaft, however, the actual original motors are the same size and will fit all!
Here is a link to the Roco parts sheet for 33206:

The motor is still available from Roco it is part number 85015 and is about 50 euros + postage etc.
With this cost in mind you have three options:
Get a complete new loco.
Get a second hand loco in working condition and swap the motor.
Get a replacement motor from Roco for about 50 Euros.
Fit a replacement coreless motor from Tramfabriek for 25.50 euros + postage. But note that you may need a modern controller if you do. https://translate.google.co.uk/translate?hl=en&sl=nl&u=http://tramfabriek.nl/&prev=search
Brian, the coreless motors I sell through the Tramfabriek work great with traditional controllers I have by Trix and Fleischmann, from the 80's. It is true you'll get an even better performance using fx the Gaugemaster Model W controller, but that doesn't mean that you need a modern controller to get the advantages of this coreless motor. The coreless motor doesn't work on controllers with feedback switched on, though.
Roco's motor, btw, is hugely overpriced. I know I am biased, but it wouldn't make sense to buy the one from Roco. The coreless motor gives way better performance, very obvious at slow speed.
The only problems with coreless motors, and I use a lot of them, are that they do not like feedback as Sven says and also they do not like pulse power of any sort which includes the Minitrains PWM controller.
I have been away from the forum for a little while, due to a major crash of my laptop. I lost most of the data, but now back up and running, I can update you on my loco issue. I had a brainstorm which directed me to an old Tenshodo spud unit in my spares box.
I had to modify it by:-
1. Removing the shaft at the opposite end from the brushes.
2. Remove the worm from the remaining shaft.
3. Remove the worm from the dead motor.
4. Bore out the above plastic worm to be a push fit on the Tenshodo shaft.
5. Using scrap pieces of plasticard an open box made to hold the motor in position laterally.
6. A piece of brass wire formed to be a spring clip to hold the motor down vertically, in mesh, as it sits at an angle.
7. No mods were needed to the body as it just fits over the motor and it runs beautifully!
It sounds a lot, but it took no more than a couple of hours including thinking time. I will try to put a photo up, once I have been taught how to do that!!!
So back from the "dead" scrap line, saved from the cutter's torch, to live and run again.
Happy modelling folks,
Happy bunny, Tod
If it is the Roco diesel with the worm gear on the motor shaft this version went out of production over 35 years ago now!
The later version with the spring drive and the gearbox at the front was introduced in about 1980.
