re assembling a 2-8-0

[Anonymous]

I recently had to disassemble my spectrum 2-8-0 to add a constant light circuit, but when I put it back toghether and operated it, it made a buzzing noise and then it stalled with the motor still running. I suspect that the wormgear isn't aligned with the wheel's gear, any ideas to correct this?

The wire to the new lighting circuit may have gotten tangled up in the worm gear or drive shaft. Disassemble it again and check your wiring.

it's not the wiring, the gears are not aligned so the motor runs but the loco doesn't move

I've never disassembled my Spectrum Consolidation and don't have the exploded drawing handy right now, but other Bachmann models use a rubber belt drive instead of a worm gear. Try to locate your assembly diagram and see how the drive train is assembled. If it does use a worm gear, the lighting board you added may be preventing the boiler from seating properly back down onto the frame, thus holding the gears apart.

I checked that also, and I guess I didn't place the wires right so apparently the are holding the motor a little to high. One more thing, it seems like the reason for which I opened the engine in the first place burned out during a photo shoot... murphy's law once again

For some reason I'm still having trouble with that engine. after solving that little flaw I wanted make a little test run, but when I flipped my power pack on, the headlight came on but didn't move, then I realized I mistakenly hooked the wires on AC instead of DC (don't ask). When I put the wires where they should be, and added power, the engine didn't move, I opened it again to see if anything had burned or something, but everyhting seemed fine, now it turns out the motor won't move unless i spin the flywheel a bit, is there any fix for this or do I have to replace the motor?

Hello there!
I suggest that you try to clean the brushes and the collector on the rotor first - the collector consists of five (more likely in new models) or three metal parts - depending on how many poles the motor has - forming a "ring", and the brushes slide on the collector. Sometimes the grease, oil, dust and carbon particles coming off of the brushes can fill the little grooves on the collector and cause the motor to short circuit. You can carefully clean those grooves with a needle - avoid scratching the collector, and fini***he cleaning with alcohol. If that doesn't help, judging by the symptoms most probably one of the poles of the rotor is burned, in which case you need a new rotor.
Just go slowly and patiently. Good luck & best regards from Croatia!
