You should be able to get an axle, with brass gear..
Google 'Bachmann Europe'..

You may have to order one from the Bachmann Estore in the USA - yep, you've got to pay extortionate postage but it's well worth it - they're lovely locos.
The chassis dismantling is fairly straightforward, just lots of screws and you need to dismantle a fair bit of the motion to get the axle out.

I did both of mine a few years ago, but if you're stumped at any point, I might
be able to steer you through 
If you arrange the wheels and motion, so something is horizontal (or vertical) then take photos on your phone of both sides, you have a reference to gets things in the right place when you put it back together.
Same when you take the motor-block apart..
Check if screws are different sizes, in different positions. - They may be the same gauge (diameter) but different lengths.

Just remembered - if you should drop a screw into the works, wait until you have got the lower chassis cradle holding the axles in place before you turn the loco over to shake the miscreant screw out. Otherwise you get absolutely everything all over the floor
Don't ask me how I know

philp thanks again for all your help -the part came today(it was the axle with the gear fitted)-removed all the bits and pieces but noticed after removing the original axle and gear the remaining gearbox housing seemed quite loose -your pdf instructions mentions that during reassembly you have to lift the gearbox a little -so is it kind of floating around until its all back together or does this mean the motor is loose -its just that i am reluctant to take the boiler off if i can get away without doing it -best regards
It does float, because of the sprung axle. I'm not sure of the motor fixing arrangement (I've never dived in to look) but for obvious reasons it's not rock solid - it just needs to be retained to prevent it winding round the axle. From your description, yours sounds normal / OK.
One of the necessary fixes with these locos was to use a little bit of Loctite when putting the motion screws back on. Loctite 248 thread locker is good for this as it will allow you to removed the screws at a later date if necessary.
Another little trick:
When putting the screws back in, if you rotate them 'backwards' (as if undoing them) you should detect a slight 'click' as the thread on the screw drops into the thread cut in the plastic..
This makes it a little easier to drive the screws, and does not chew up so much of the inside of the mounting holes.
Don't force the screws..
If it won't pull closed, you have something trapped, or not sitting correctly..
I sometimes find I have a problem, and a loco just won't go back together. - Leave it for a while, and come back to it.. Then work through it again.. It is then you find the trapped wire, or something not quite sitting correctly.
