Tools Required

A selection of cross head and normal miniature screwdrivers

Small pliers

Small plastic bags and labels to identify parts and screws when dismantling

Small files

Soldering iron (for electrical connections)

A steel rule

Back to Back wheel gauge

Plastic solvent, superglue and epoxy resin (24 hour and 5 minute)

In all cases, bag and label all small parts and source of screws as soon as removed (they are all different) - trust us on this one!

Dismantling the Locomotive

Unscrew the front and rear screws, pull the chassis vertically to remove it from the body.

To remove the keeper plate (with brakes attached), remove the remaining screws to allow the keeper plate to be removed and remove the wheels.  Remove the glued-on sandboxes (by twisting with pliers) and sand pipes from the keeper plate. Store these for use later.

With the wheels removed from the chassis, unscrew the machine screws from the wheels and remove the coupling rods. Put the screws back into the wheels for safekeeping.  The chassis should now look like the photo.

De-grease the chassis sides.

Hold the centre wheels and with a twisting pulling motion pull off the wheels from the axle. Also, slide off the brass bush.

Place the axle with centre gear in a vice such that the gear wheel is supported on the vice sides but the axle is loose. Tap the axle with a hammer or similar and the gear wheel will slide off the axle.  If you do not have a vice use a pair of pliers on one side of the gear wheel, gently slide the plastic gear down and off the axle by holding the axle vertical and pressing down. It is very important not to damage this gear.

You will now have a box of bits and an invalid Bachmann guarantee!
