I wonder whether you have put the body on with the motor in that configuration? I'm doubtful that it would fit and not foul and short out on the top; also there is very little space between the firebox sides on the Wills saddle tank which are quite heavy castings. You may have to remove some metal to get the motor in. For these reasons I went for a different gearbox setup as previously described,

Well, I think I've measured it out ok but I'll try it out, possibly this evening, when I get home and I'll let you know. I'm using one for Chris's new ish coreless motors which is only about 13mm dia. But as you say it may be too long...time will tell!
Thanks for your advice on spacer attachment and your concerns over the space I'm allowing for the motor being vertically mounted in the firebox. I have now tried it out and all appears ok. Take a look at the photos and tell me what you think, if you would. Having said that, I don't yet know if this quite small motor will have enough grunt to spin the wheels if necessary, we'll see.
Here you can see how far the motor extends.
And here if you peer into the murk, you can just about see the top of the motor through the safety valve hole in the top of the tank. It lies about 4mm or 5mm below the tank underside.
Here's hoping it all works out.
