3D printed replacement axles and gear for the no longer available Bachmann J72 split chassis locomotives.
New revised tooth geometry. We have re-engineered the gear to overcome some of the 3D printing process limitations, and the gear now meshes with the worm drive much better and gives improved running.
These parts have been reverse engineered from the original Bachmann parts and are 3D resin printed. Each set comprises of 2 plain axles and 1 gear axle. See our other
j72 listing for square drive version, this is the round drive version
Note: You will need a back to back gauge to correctly set the wheels on the axles, and you will need to correctly quarter the wheels to ensure the connections rods and cylinders function correctly. As this is a round drive loco kit, you will need a jig to correctly quarter the wheel sets.

3D printed replacement axles and gear for the no longer available Bachmann split chassis steam locomotives.
New revised tooth geometry. We have re-engineered the gear to overcome some of the 3D printing process limitations, and the gear now meshes with the worm drive much better and gives improved running.
These parts have been reverse engineered from the original Bachmann parts and are 3D resin printed. Each set comprises of 2 plain axles and 1 gear axle
These axles were fitted to many different early Bachmann split chassis steam loco’s. We know they were fitted to V1, A4 and 43xx Mogul, but it is not possible to come up with a definitive list as there are so many variants. To check your loco, please remove and separate one wheel set. If the centre axle pin is square and approximately 2.05 x 2.05mm , the outer diameter of the gear is approximately 14.7mm and it has 28 teeth, these gears will fit.
For smaller 0-6-0 locos, please see our other listings.

These parts have been reverse engineered from the original Bachmann parts and are 3D resin printed. Each set comprises of 2 plain axles and 1 gear axle
These axles were fitted to several different very early Bachmann split chassis steam loco’s.

3D printed replacement final drive gear to fit a Heljan class 23. There are 4 final drive gears per loco, but these are also used as one of the intermediate gears in the gearbox meaning there are 8 in total in the loco. This listing is for a pair of gears, to replace the final drive gears on one bogie.
A pair of resin 3D printed replacement buffer beams, retainers and coupling droppers to fit a ViTrains class 37. Please note, these are just the plastic part and do not include the coupling dropper springs, which will need to be sourced from elsewhere.
A pair of resin 3D printed replacement couplings to fit a ViTrains class 37. Please note, these are just the plastic part and do not include the metal hook which the customer will need to source from elsewhere. These are printed in high strength resin.
A pair of resin 3D printed replacement coupling droppers new conversion to fit a ViTrains class 37. Get rid of the ViTrains couplings and fit Kadee couplings to your ViTrains 37 with our new NEM pocket conversion kit. You will need the short NEM Kadee couplings to use with these pockets as the bracket hangs down rather far forward to meet the exact NEM position to buffers standard.
We will be closed between Sunday 14th June and Friday 26th June 2026. Any orders placed during this period will be processed on our return. We wll have limited email access during these dates, but will do our best to respond to any messages as quickly as possible.
Due to increased costs, documentation requirements and the EUs plan to introduce fees to ship products into the block, we now no longer offer shipment to anywhere except the UK.
