Any road-up:

I do not think you will find a 'complete' axle/gear/wheel assembly, but you do not need it.

The axles will be fine, so you need a new gear, and if you are being 'really' finnicky, possibly one new wheel? - I think from what you have said, one wheels was not square, on the axle. This I would expect if the gear was worn, as it would slip/jump, and that would put pressure (via the rods) on the wheel,as things became stiff, or actually jammed.

LGB 34 tooth gear

Ah, right, I see what you mean. Here is a pic of the screw.

Its a hexagonal head, about 15mm long and about 2mm at the thread diameter. Not self tapping.

Ooooh, now that looks interesting. You are right, I'd be quite happy to just get the correct cog. I don't even need a wheel as I could most likely make use of one (or the pair) from the wheelset I bought.

Of course, my big question.... is this a pic of the cog I need... and if so, how do I go about ordering them?

CL30338 has 34 teeth.
CL30049 has 28 teeth and is for Toytrain steam locos (i.e. Otto & Oho).

I have both in stock (though CL30049 is not listed on the website yet).

Noted and documented as another source for axle gears, and cheaper?!

Thanks for the measurements. Sorry I didn't get to this at the weekend. 28 teeth at that size is not as close as I'd expected to a round-number "module" metric gear size but it's almost bang on Imperial 48DP. I don't think I have one of those on hand I'm afraid but if all else fails, it might be worth trying a cheap generic 28 tooth 48dp gear and seeing if it meshes, since they're quite common in RC cars and go for a few £ at most. But it looks as though all else has not failed and you have a good chance of getting an exact part.

I'm astonished by the price on that elriwa.de link... seems like they don't really want to sell them. Muns' shop seems like a much better bet.

Problem is:
That link has focused you all on the 28 tooth gear..
The OP requires the 34 tooth gear, and depending on the Postie, should be sorted?

"fine cog has 28 teeth, the coarse cog has 20 teeth"... I thought that meant it was the 28t (which looks obviously very worn) that wanted replacement, with the 20 being too fine? Never mind, all fingers crossed that it's sorted.

Are you sure Phil????

The OP stated that his rather worn gear had 28 teeth...

The fine cog has 28 teeth, the coarse cog has 20 teeth. Both are 16mm diameter and 5mm width.
The 38tooth gear has a larger diameter, ~19mm vs ~15mm.

So I think the problem is yours :)

I'm sure you all like a happy ending. The gears from Mark at Garden Rail Outlet were the correct ones, and once fitted (and jings, that's no as easy as I thought it would be), Casey runs smoothly once again.

My thanks to everyone who took the time to respond.

Here are a few pictures of her first run after returning from the workshop.
