Hi John,

Why not just buy the Piko model?

Thanks for making me aware of it.

I just had a look and at Euro 254.00 looks a bit expensive comparing their other range of locos.

plus you get a special tool to open or separate the housing from the frame but its a different story when putting it back again, not a task for the light hearted.
Don't think you can add a sound decoder and speaker.

John

Hi everyone,

Here are the first photos from an atempt to convert a Märklin 3001, 3002 loco from analog to digital.

2 photos have a lokpilot inserted (21 pin), 1 photo has already an ESU sound decoder installed.

1 Photo shows you the ESU adapterplate 51968 (4Aux functions), Ive drilled a hole through the adapterplate and it fits nicely with the screw hole behind it (loco frame), a small thin plastic washer has been place between the adapterplate and the frame

1 Photo the Roco telex coupling

1 Photo each shows the led's,
ballbearing, here you can see there is some room behind the perm. magnet and I hope the small speaker fits into this space and this is it, there is more room for anything else.
5 pole highefficiency motor

2 photos show the handrails and footsteps

1 photo shows the other under side (doesn't look good ) but this where the 2nd Roco trelex coupling will be placed.

When I first look at the loco I didn't think it all would turn out as it has, there are improvements and new ideas with each new conversion to use the space and wire connections as wise as possible.
although some solder pads from the adapterplate are so close to a specific connection I've waved the idea to use hard wire because the smallest movement rips the solderpad off the circuitboard.
again there will be 2 micro connectors for the top lights and I hope I can work this one out as well (space)

Because the wheel frame is the same distance as from a BR 191, I'm trying to see if I can add the brake pads on this loco as well

regards.,

John

Francisco,

thanks for your respond

ESU has bought out a new square loudspeaker, especially for locos where room is an issue.

Jacques, thanks for the tip but I haven't experienced it with mine.

I'm almost finished with the conversion and yes a loudspeaker does fit behind the perm. magnet.
the crucial part was the adapterplate from ESU, being able to drill a hole through it and finding it lined up where the previous screw hole from the reversing unit was, one needs a bit of luck which you altering locos like this.

regards.,

John

Jacques you think one has to have an eye for it ?

John

Hi John, looking great!
we need a video to see the sound working!
it maybe tempting...

Thanks Francisco,

Here is the rest of the family:

2 Märklin (E 63 02), 1 Hobby (E 163 Sound), 1 Primex (E 6308)

Mark,

thanks for your comment.

at the time there only had been 2 on the market Krois and Roco. Roco had trouble producing them because of patent rights, Märklin new version telex coupler came much later so I can't tell you which one is better or more suitable.
Roco's coupler however picks up every little bit of metal you may have lying on the track, on one side a good automatic cleanup tool but on the other side it can prevent the coupling of working.
another must is for the opposite coupling to be compatible and the same height. Roco's counterpart coupling (40397) works well

regards.,

John

Impressive performance John!!!!!
The tiny speaker works great, it is part number 50326 right?
Francisco

Sorry for bringing up this 'old' post but I have a 3002 running with an Uhlenbrok decoder which did not need to change any of the motor parts.
If I want to change the motor which of the Maerklin kits do I need?
Will the 60943 work on this engine? I'll use a LokPilot 4
Thank you

Hi Ray, thank you very much for your advice. So I keep the 3 pole rotor as is and with the ESU kit, you mentioned, I convert the loco.
Isn't it a bit of a waste though to use an MFX decoder on an engine that has a 3 pole rotor ?

The original engine of the 3002 is an LFCM or not ?

Cheers

thank you. is there an old topic in this forum about the Maerklin motor types or I saw it somewhere else?

I got the same loco and thinking about to convert it to digital. It is still anlogue. I found these technical specifications for the E 63.

Good advice Jacques!

I have seen this problem in the past, where removal of the reversing relay affects the adhesion weight of the loco. I use chunks of fishing weights to achieve the same result.
