'Gordon' 4-Wheel Drive Chassis Assembly Instructions
It is suggested that you read these instructions through before commencing construction.
A minimum of tools are needed to assemble the kit. Sandpaper and sanding block, some strong
rubber bands or weights to hold parts in place while the glue dries. You will also need a small
cross head screwdriver to attach the motor and soldering equipment to assemble the wiring.
The included motor is designed to run on 2 AA batteries (Not included). These can be either
rechargeable or disposable. (In an R/C setup you can use a maximum of 6v with this motor)
This kit requires glue and paint to complete. It can be built entirely with PVA (exterior type) or
aliphatic resin, except for the grille mesh which is best attached with epoxy resin. A favourite
glue is Titebond 3 aliphatic. Excess glue can be wiped away with a damp rag.
As MDF is by its nature not moisture proof the model should sealed before use with MDF sealer,
thinned PVA or automotive primer. The cut edges may need more than one application of primer
to seal them. To finish the model cans of automotive spray paint work well and give a good
finish. If brush painting then use acrylic or enamel paint.

A minimum of tools are needed to assemble the kit. Sandpaper and sanding block, some strong rubber bands or weights to hold parts in place while the glue dries. You will also need a small cross head screwdriver to attach the motor and soldering equipment to assemble the wiring.
  • Page 2 Assembly Carefully separate the parts from their sheets. Wriggling them lightly is normally enough to break the retaining tab. Sand the retaining tabs away on all parts before beginning assembly. Start by attaching the motor supports to the chassis cross member Attach the brake parts to the chassis cross member with the etched detail facing outwards.
  • Page 3 Attach the chassis baseplate to the chassis sides and cross member Attach the inner buffer beams to the chassis Insert the body locators into the loco base. Glue the loco base onto chassis. The body locators will only allow the chassis to fit the correct way onto the chassis 3 of 7...
  • Page 4 Assemble the buffer beam overlays and coupling parts by stacking the three coupling parts into a sandwich with the cut away one in the middle. Add the coupling and buffer overlay to the chassis Add two washers onto each end of the axles, then add the top hat bearing with the flange outermost Fit the wheelsets into the chassis.
  • Page 5 Assemble the axle boxes by layering the five parts for each axle box as shown. Glue the axle boxes to the chassis. Make sure you don't allow glue to seep into the bearings. Align with the top of the chassis. Glue the three motor holder hoops together as shown in the picture.
  • Page 6 The chassis is now fully assembled, just add the batteries and switch to complete. If using this chassis with our Gordon loco body the switch fits in a hole in the cab front wall. The body is designed to be a friction fit onto the chassis between the body locators.
  • Page 7 Troubleshooting. If the nylon worm gear wears very quickly it is usually down to one of two things:  Ensure that the nylon gear is central to the brass gear when running in both directions and adjust if necessary. A 0.6mm hex key is required to adjust the brass gear When assembled correctly there will be a minimum amount of end float of the wheelset.
