I had a couple of locos with that chassis MG. I guess it could be mounted either way round.

It could be. I no longer have mine to check. The problem is that to correct such an issue I've not tried as I have not come across it as yet. I do have a Thomas somewhere as I'd bought it cheap as a non runner and fixed it up, but this works fine.its con rods are held on by mini carpet tacks as I couldn't find the correct crank pin thingies for sale at the time I needed them. It actually works well as it is so is never bothered changing them since. Thomas amused my youngest brother and was in service throughout his youthful years untill finally he wanted to swap his trains for my scalextric collection. He is not really into trains these days like I am.

Yes at all speeds,maybe I'll contact Hornby,maybe mountain goat has a point .loco is DCC fitted and therefore wheels are very narrow and back to back measurement is more important . thanks for your help

I've never tried it myself. The only advice I can give is to go easy with any adjustments, just in case. I have done back to back adjustments. For these go carefully so you dont upset the wheel quartering.
Wheel quartering is where the connecting rods (Con rods) of the wheels on one side of the locomotive need to be a quarter of a turn different to the wheels and con rods on the other side of the train. If one wheel is slightly out you get a banging noise and if one or more is very out the thing jams up.

I have never had to adjust the back to back on driving wheels.

I have, but normally due to projects where I've changed wheels or changed chassis etc.
I really need to get me one of those back to back gauges. I tend to match them up from locos or wagons I know are correctly set, so if mine are out it is not by much.
To be honest it is with wagons that I tend to check the back to back measurements with, especially if I go changing wheels on Triang cast chassis as I need to slide new wheels onto the Triang axles.

Yes I have when changing wheels but never out of the box.
