The LFCM is recognized by one carbon brush and one copper brush, connected to a flat collector. The motor cover is rather big, and comes in two versions, with different motor covers. The two different motor covers, as well as two different rotors, comes with the conversion sets.
In a locomotive it may look like this:
This is the original LFCM in a Märklin 3068 locomotive. The motor from a
609?4 conversion set will not fit directly with this motor.
See the conversion of my Märklin 3068 NSB Di3a 3.641
The conversion sets:
There have been three different conversion sets for locomotives with the LFCM
motor.
Set | motor | decoder | Remarks |
---|---|---|---|
60904 | 5-pole high power motor |
c91 | No longer produced by Märklin |
60924 | mfx | ||
60944 | none | A decoder must be bought separately |
The c91 decoder in 60904:
This photo shows the c91 decoder without it's plastic cover. The lamp on
the top does not belong to the decoder.
In the 60904 it was (not produced anymore) a so called c91 decoder, with a row of eight switches (so called Mouse Piano) to set the decoder address and two potentiometers to adjust the maximum locomotive speed and the acceleration/deceleration time. The decoder receives data from the digital train controller, one way communication only. With a Märklin control device you may select between 80 locomotive addresses. The decoder dimensions are 36 x 21x 9 mm. If required, it fits into a holder 258820.
The mfx decoder in 60924:
In the 60924 conversion set we find a mfx decoder. It means, among others, that the decoder
is adjusted from outside, from the train controller. You can set a lot of
things, like the address (if you use a Delta controller or the 6021 Control Unit),
the maximum speed, which can be set rather accurate, the acceleration and
deceleration time can be set individually and you have some control of the
different functions of the decoder.
If using The Märklin Systems, either with the Mobile Station or the
Central Station, the decoder is reporting itself to the control system, two way
communication.
It is not necessary to set an address. The decoder dimensions are 22,3 x 15,5 x
5,5 mm. If required, it fits into a holder 456200. This decoder is
wrapped into a sort of rubber tube in the conversion sets.
The Märklin conversion sets 60904 and 60924 are no longer available from Märklin, and are replaced by a separate motor set and a choice of separate decoders.
The new motor conversion set, 60944:
The conversion set 60944 is the motor and small parts only. I think these
parts are identical to the motor parts from 60904 and 60924, but I have not seen
them yet. The decoder of your choice must be bought separately.
There are four different decoders types to choose from:
The new decoders:
60942, mLD, multi protocol decoder (mfx, MM1, MM2 and DCC) with an amplifier board,
six function outputs
60962, mLD, multi protocol decoder (mfx, MM1, MM2 and DCC) with wires and an 8-pole
NEM connector, four function outputs
6094?, mSD, multi protocol sound decoder (mfx, MM1, MM2 and DCC) with an amplifier
board, six function outputs and speaker
6096?, mSD; multi protocol sound decoder (mfx, MM1, MM2 and DCC) with wires and an
8-pole NEM connector, four function outputs and speaker
The sound decoder's number last digit: 5 is for steam engines, 6 is for diesel
and 7 is for electric locomotives.
The mSD decoders
60948 and 60949 has special amplifier boards suited for the 36-series Hobby
locomotives with bogies. 60948 for diesel engines and 60949 for electric
engines.
The mSD decoder 60940 has a 21 pole mtc connector, to fit into locomotives
with a factory fitted mtc21 amplifier board.
See this Märklin web site for detailed information.

Installation in a locomotive:
A number of locomotives may be converted without
any problems, but some require additional work. If you have some
mechanical and soldering skills, it is normally no problem to install the
conversion set into a locomotive. The locomotive must of course be in a
good mechanical condition prior to the conversion. If you don't have the
skills yourself it is recommended to leave the work to professionals, like your
Märklin dealer or the Märklin Repair Service in Göppingen, Germany.

The decoder functions:
Function | Direction | 60904 | 60924 | Remarks for 60924 |
---|---|---|---|---|
f0 | forward | yes, changing with direction | On the mfx decoder in 60924 these selections can be done with the Central Station 60212 or newer. In addition to the acceleration and braking delay, this decoder also have a shunting speed setting, normally also controlled with f4. This may be set to e.g. f3 with the Central Station. Also the output type and intensity can be selected, like light, flashing light, smoke unit etc. | |
reverse | yes, changing with direction | |||
f1 | forward | yes | yes, one direction only and/or on/off with start or stop may be selected. | |
reverse | ||||
f2 | forward | yes | ||
reverse | ||||
f4 | forward | acceleration and braking delay cancelled |
Shunt speed and delay may be separated | |
reverse |
A Central Station screenshot:
The left half shows an mfx decoder, identical to the one in the 60924 set, the right half shows a c91 decoder, like the one in 60904. The different functions are indicated far left and far right in the picture. From the top we have f0, front head lamps, f1, for instance interior light front end, f2, for instance Telex rear end, f3, shunting speed (not on the c91) and f4, cancelling the acceleration and the deceleration delay. The function order and position (which key to press) may be altered with the mfx decoder, but are fixed with c91 decoder.

There are many internet sites regarding this kind of conversions and how to solve the difficulties. Just search for Märklin 60904, 60924 or 60944 conversion.
