You can use Helmut Kern's website to help with motor identification for most Marklin locos up to about 2004.

The AJCKids website in the US has lots of good info on conversions, including a table of motor types

http://www.ajckids.com/TRAINS/MAIN.ASP?nr=92

There are 3 motor conversion kits:

60941 - DCM conversion kit
60943 - SFCM conversion kit
60944 - LFCM conversion kit

So, for your locos

3098 BR 38 - SFCM
3083 ETAT - LFCM - see https://www.marklin-user...p-needed.aspx#post249506
3094 Streamliner - LFCM
3084 (BR 50) - DCM - see http://www.saebonet.com/svein/Tog/sites/d/3084.htm

Keep in mind that the LFCM can have 2 armature types (7 tooth and 8 tooth versions) and 2 different motor face plates. You need to select the correct types for the loco you are converting. Both types are included in the 60944 kit.

Good to see you are still here and active! I read a number of your earlier posts and you list a lot of links to material I would like to read. The links from back in 2009 unsurprisingly no longer work. I was interested in the Marklin_Insider_-_Marklin_Digital.pdf file. Do you still have it around?

Cheers and thanks for the quick reply.

Kim,

What you will find out of the 4 locos you can convert 1 with a digital conversion set 60901 (3084) without modifications.

all the others need special attention to be able to fit a new brush plate (60904) for a high efficiency motor to be installed.

however you could use an ESU permanent magnet and use the current collector and brush plate.
so before buying up big and wasting your money you may have to follow the links which have been provided, I did a successful conversion for one of our members but can't remember how I did it.
What you will find using the 2 options I've mentioned by using the perm. magnet you will not get the smoothness at low crawling speed and the other option you have to make modifications and again if you stuff it up you need a new brush plate.

regards.,

John

Hi Kim

Far from being a conversion guru, after all of two conversions, I have converted my Marklin BR12 (3310) with the Marklin 60760 kit and I have put an Uhlenbrock 75000 into my BR216 (3074).

I am really not good with electronics and feel completely out of my depth, with some assistance from Johnvr, it's actually a breeze. The 60760 kit comes with all that is needed (motor included) and besides a little soldering it's close to a 'drop-in-and-play' option. I am not sure about the other loco's you have but the 60760 will work for the 3084. I plan on putting this kit into the two 3084's I have.

The Uhlenbrock 75000 is just the decoder, so if your current motor needs replacing then you would need to source that separately. Unfortunately the motor in my 216 does need replacing so although it is now digital, it's running characteristics are not all that great.

Hope that helps in some way.

If anyone is interested I have a blog about what I am doing here:
