I've got a Liliput Zillertalbahn 0-6-2T where the wheel rims have worked loose. After an unsuuccessful attempt to araldite them back in place, I had to resort to obtaining a spare wheelset from Bachmann. I've stripped the loco down by unscrewing every screw I can find (including the chimney) and have a nice box of bits ... but the old wheelests are still in place! I'm guessing there's a keeper plate somewhere I need to remove - but how do I do it?

Hi Richard
There are two different chassis used in the 0-6-2 over the years. The older one dating from the 1970
You'll have a hard job getting the keeper plate off - there isn't one! :o
At least there is not one on the older chassis that I have... Bachmann have a habit of changing chassis designs for no readily apparent reason (except perhaps for ease of asembely by the Chinese workforce) so the modern design may be different.
I would guess that if your new wheelsets have the gears set behind the wheels down one side then the designs of chassis are the same (or close enough to be compatable). However it may also be worth comparing the gears, as it is not impossible that the ones on the new wheelsets Bachmann have supplied are different to the ones on your chassis (diameter, number of teeth). On the chassis I have the gears are seperate from the wheel they are behind and sit on a splined hub. So it should be possible, once you have the wheelsets apart, to swap the gears over.
If the new wheelsets have the gear in the middle of the axle then they probably will not go in and you'll need to rethink things.
Assuming that the design of yours is the same as mine, to get the wheelsets out you'll need to pull a wheel off the axle.
Before you do anything, check that the replacement wheelsets have the same diameter axle as those in the chassis block (dial or digital calipers are best for this). If they are the same, then it is a straitforward job of swapping the wheels, either by pulling the wheels off both sides and replacing them with the new ones pulled off their axles, or by pulling the wheels off one side of the chasis (go for the no-geared side) and sliding the axle out of the chassis - replacing is just the reverse. Don't forget to measure the back to back with the calipers so that you can reset the new wheels to the same distance (or get a back to back gauge for N / 9 mm gauge).
If the new axles are a different diameter then you will need to either make the axle holes in the wheels bigger and use the original axles (if the new ones are smaller), or make the holes in the chassis block larger (if the new axles are bigger than the old). The best way to do either of these is to use a tapered cutting broach to carefully enlarge the holes, making sure that you do not go to far and make the holes too big - especially if working on the wheels!
If you do not think your skills are up to the task it may be worth getting in touch with Brian Guilmant (Sales Officer - details on Page 3 of 009 News) to pass on the details to Ian Turner. Ian does all the servicing and repairs to the sales stock when it comes in and is a wizard when it comes to loco chassis. He can probably convert the new wheelsets to fit, or may even have a replacement set of 'old style' wheelsets to put in the new wheels will not fit.
Hope that helps.
Julien.
Thanks for confirming my suspisions of there being more than one chassis design Brian. Your replay came in as I was typing mine, and thinking about it using one of the specialized locktites to re fix the original tyres may be much easier.
