Problem with loco.

[joegriffin1984]

Hi all, Im having a problem with one of my locos. When you power her up to go, shes making a revving like noise but not moving. Its like she wants to go but somethings stopping her. The higher I turn the power controller the higher the noise from the loco. Any Ideas?

Which loco is it?

 

Some of the ones I have with flywheel motors connect to the bogies via 'power rods'. These rods can become disconnected from the motor if the box gets knocked about, and the symptom is usually exactly what you describe.

 

Pry off / unscrew the body and take a peek - you should see the connections are off / loose. Should be a simple enough job to pop them back into place and you'll be underway again

Is it easy enough to do? Its the steam loco off the Hornby Mainline Steam set.

You will need to pop the body of and check that the worm on the end of the motor in engaging the gear sprocket

Ok so this is where Im at now.

Do I need to remove the two screws in photo 2 underneath?

Have you tried running it with the body off - so that you can see what is/isn't happening?

[joegriffin1984]

Tried it there. Still making the same noise. The two circles in the photo below, these parts are spinning around when i open the throttle up. Dave said I can drop it over to him if I cant fix it.

The worm - the black plastic screw on the end of the motor shaft - should cause the gear that is underneath it, parallel to the main wheels, to rotate.

[joegriffin1984]

No probs. Thanks for the advice folks. Ill think I will drop it over to Dave whenever I get a chance.

If the motor and worm gear are spinning freely then it could possibly be an issue with the connecting rods on the main wheels being slightly out of sync.
