Replacement axle and gear set for Bachmann split chassis steam locomotives

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.

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.
