INSTALLING THE EDM MODELS REPLACEMENT CORELESS MOTOR IN A BACHMANN 0N30 SHAY<\/span>\"\"<\/a><\/h2>\n

Faced with a Bachmann 0n30 shay that the motor had failed on and finding the Bachmann UK had not spares at all and that Bachmann USA only sold a complete motor gearbox unit some lateral thinking was needed.\u00a0 I could have ordered a new unit from the US but as I am based in the UK the cost of the shipping was more than the cost of the parts but I also have these coreless motors in stock for other projects. The result was a kit to re-motor the Shay with a high performance 12v DC coreless motor using a 3D printed adaptor.<\/p>\n

Bit of an Oops<\/span><\/h3>\n

A very small number (about 4) of these kits have escaped with the wrong length sleeve used in their assembly. As a quick check the distance from the motor to the outer end of the gear should be around 12mm. On the escapees the the distance is around 15mm. With the wrong length shaft the gear will miss the gear its supposed to mesh with and foul on the bottom of the gear case.<\/span><\/em><\/p>\n

Theoretically, the fix is push the worm up the sleeve 3mm and cut the excess off but there are some potential pitfalls as rthe worm is very tight on the sleeve so I suggest you contact me for guidance.<\/span><\/em><\/p>\n

SOME THINGS TO NOTE<\/h4>\n

These are the instructions for the kit so are here in the instructions section but there is an entire discussion page here\u00a0 https:\/\/ngtrains.com\/blog\/bachmann-0n30-shay\/<\/a><\/p>\n

The loco in the following pictures is a bit of a basket case that it slowly being rebuilt to be an 0n3 model with a wagon top boiler but it illustrates all we need to see here without taking a complete model apart<\/p>\n

The motor shown in the following photos is a double shaft model. The ones supplied in the kit has a cut down shaft as its about 3mm too long<\/p>\n

You can buy the kit on my website www.ngtrains.com<\/a> at the time of writing the exact location is here<\/a>. If that doesn’t find it look in the motor section or search “motor upgrade”<\/p>\n

Step 1 – remove the Ashpan Casting<\/span><\/strong><\/span><\/h4>\n

\"\"<\/a><\/p>\n

Remove the two arrowed screws and take the ashpan casting off.\u00a0 Note – the `beak’ faces to the rear when it goes back on. Also if your line has a hump in it and your shay catches on it this will be the bit that catches – leave it off<\/p>\n

Step 2 – Prepare to remove the Drive Unit<\/strong><\/span><\/h4>\n

The base of the boiler unit and the cylinder unit come out of the loco as one.<\/p>\n\n\n\n
