I was a bit suspicious that it didn't look right so I contacted my supplier who advised that it had the right tool to remove those screws. Of course, when it arrived it didn't, the screws are 2mm on those locos and the smallest nut driver in the set is 2.5mm. It seems like this is a major omission from the tool set for recent locos. The latest advice is to try a small pair of pliers. Fortunately, I do more than enough small mechanical work for me to easily justify buying extra tools - a Wiha 26592 set of miniature metric nut drivers is on its way. If you just want the single 2mm one it's a Wiha 26520. What do others use or recommend?

For instance I tried to access wheel tires on a 2023 Märklin steamer and I had the surprise to see that the hex screw was smaller than any of hex screwdrivers in the kit. That said the vast majority of my locos (approx 150 from 1949 till 2024) can be serviced. IMO the most needed parts that are not in the kit are: - a pair of clockword tweezers (I got mine from a visit in Switzerland in 1955 DUMONT factory) - a very thin screwdriver (less than one mm) to install correctly a traction tire and also to dislodge a wheel tire (yes it goes also very well by pinching the tire with tweezers) - as earlier explained a set of female hexscrewdrivers of very small metric dimensions - a LED large magnifier Cheers Jean

Also, available from a proper model railway company , Hornby R913 Con Rod Spanner 2.0,2.5 mm - will fix that glaring gap in the Marklin tool set.

Joined: 04/08/2018(UTC) Posts: 997		Those Wiha screwdrivers are very good last year i bougt Micro Combination spanner/wrench set from Donau Elektronik, as a suplement to my Wiha set. mostly for easier acess to some nuts on wheels etc. Coupler and smoke generator for size reference I have this Wiha 92092 set (ESD safe version): I use it quite often, not only on my Märklin but on many other things as well.

Well Mark I have the Hornby Rod Spanner, so that will suit me. In fact having run Märklin trains now for 19 years, I can only remember once or twice having to remove a rod nut to replace a tyre. And in one case, the loco (an Insider) was brand new, and the tyre was all twisted so the loco jumped along the track. But I use the 70900 tool kit tweezers and screwdrivers constantly so I have one in the layout room and another in my workshop. An alternative to the Wiha is the Expo 78040 small spanner set of 6 drivers which they call a Nutrunner set, very reasonably priced. I purchased the set from an English model shop when ordering other stuff. Maybe it is available in Australia, I never checked. Kimball

Seems like the best set out there for all kinds of super small nuts and hex head screws. I just bought two used 36244 locomotives (one with and one came without smoke generator). Both in need of some repairs, previous owners screwed up, but they never told me. One has probably fallen to the floor and needs a few new parts. The other one has some serious trouble with the valve gear rods. Probably been driven with some part of the valve gear dislocated for a while. All the tiny rod shoulder bolts (E129451) were almost worn through, one was broken. And they all have 2.0 mm heads.
