Default wheel back to back query

I have an odd wagon that does not run smoothly through the points, because the wheel back to back measurement is too small. I have managed to open out to axles from 13.6, to about 14.04mm. 14.4mm is correct, but I cannot open out the wheels on a Hornby tank wagon with square axles, and bent one in the process...

I can manage to pull wheel sets with round axles, but not square! I have a digital caliper, so don`t need a back to back gauge. But is there a correct way to do this please.

The wheels are moulded onto the square axle and they are plastic. My advice is replace with metal wheels on a metal axle.

Thanks Walkingthedog, for your fast reply.

I take it that the plastic square axles are not changeable? Metal ones are certainly easier to adjust.

The square axle wheels are not very good. Hornby make replacement wheels as do other companies. You need to measure the wheel diameter across the part that sits on the rail not the flange. I have replaced all of the plastic wheels on my rolling stock with metal ones, makes a huge difference.


Just an example. They come in different diameters.

I replaced all my rolling stock plastic wheel sets with metal ones. Apart from smoother running they look so much better. They are slightly noisier though.

Thanks for all your answers, that seems to be the way to go. Ten wheels for about a tenner, should do four and a half wagons. A pack of twelve would make sense!

I thought 12 would be best. 10 does 5 wagons or 2 1/2 coaches.

Can you get these for the locos too?? I had wanted to look at the ones one my Princess, but I was advised not to take them off cos of something called quartering.

But surely the rod attached to all three wheels will keep them in the right places as it doesn't go on any other way??

Quartering means that if the connecting rod are attached to the wheels on one side at the 12 o clock position the wheels on the other side should be at 3 or 9 o clock. A 90 degrees different. Yes you can get replacement wheels but it will cost a lot.
