First off, Merry Christmas and Happy New Year to everybody!

Santa left a BR610 (#34761), that needs some TLC, under the three for me.
So first thing to do is to install a missing slider, a 7164 according to the manual, but the question is how to do that?
Manual say, just to screw it on like any other lok... but there is no contact plate that would transfer the current.... Am I missing something?

Regards

Hi
It seems to me you have a 2-rail version as we can see clearly the wheel sliders

So almost surely your reference is not correct.
The 34761 appeared on the 2000-2001 catalogue page 108 and is a Fleischmann model
34781.png (1,139kb) downloaded 10 time(s).
The following year it disappeared from the Märklin catalogue
I cannot access the explosions diagram nor the spare parts list.

So what are the Fleischmann sliders? You bogie does not seem to have a slider interface
Alternately you may be dealing with a Fleischmann model (nothing to do with Märklin) so you will have to make some mechanical adaptations and some wiring.
You may also want to have non-insulated axles for better occupancy detection
Cheers

Hi Jean Pierre
Maybe this kind of slider (Märklin E206370) would fit into the 4 holes
- 13 mm center to center between square holes lengthwise
- 8 mm transverse grip
- 50 mm slider total length

Another view of the fixing bracket

This is now a very common Märklin slider
I hope this helps

Hi Jean Pierre
Märklin has many sliders in its sleeves
This one is the E225 647
It is used on quite a number of recent locos (BR 24 and others)
Here is the overall view
Grips are oriented OUTSIDE unlike the previous one


Here is a closer view on the bracket
Notice the outward-looking grips

I hope this one fits better
Here is how it looks on the loco


Cheers
