During a recent spring-clean, I've unearthed an old motor from a Lilliput Zillertalbahn 0-6-2 (#701) - the rest of the loco has fallen to pieces. If anyone would like it for spares, I'll happily mail it to them.
There are two different types of Mabuchi motors fitted to the early Liliput locos. (I assume that is what you had as the chassis blocks were made of mazak that does tend to crack and fall apart.)
The Mk1 chassis had a short shaft with a flexible plastic coupling; the MK2 chassis had a longer extended shaft.
Although it is possible to use the motor in either type it is not an easy job to remove the shaft extension or then re-fit it to a Mk1 motor as the Mk1 motor has a shorter shaft.
Here is a Mk1 chassis with the flexi coupling and bearings for the worm shaft either side of the worm:

Here is a Mk2 chassis with the long extended motor shaft and no bearings for the worm:

Yes - it's the Mk.1 version with flexible plastic sleeve on the drive shaft.

As a matter of interest the reason the design was changed quite early on in production was because the flexible plastic sleeve on the drive shaft is affected by any oil applied to the worm or motor bearings.
This results in the sleeve slipping on the shaft with the motor running but the loco not moving at all!
