squeak in FM trainmaster

[Anonymous]

This trainmaster (made in Michigan) appears to be well lubricated but has an intermittant squeak coming from one motor or its drive train. when the squeak occurs the engine slows down as if it were encountering increased resistance.

On bench test, squeek is isolated to one of the two motors and independed of being on a track. Lubricant seems adequate. I purchased this used recently.
Any suggestions to isolate the problem & repair or should I take it to Charles Ro?

Thanks

Huizc,

You might try running the loco on the bench with the shell off. Look at the two flywheels and see if they are spinnng at the same speed. You may also be able to pinpoint where the squeak is coming from easier.

Does the squeak occur on each revolution of the flywheel or is it associated with a revolution of an axle? This will help you to determine which drive line component is causing the squeak.

If you have TMCC, try to run it on the bench as the TMCC speed control will allow you to run the engine really slow.

Regards,
Roy

Hello Huizc ! One of the axle bushings might be dry. Check the in & out movement of each axle to see it any of them are dry,If so couple of drops of Labelle oil should help.Also check the armature shaft bearings to see if they are dry. These are the areas of the engine you should look at to find your problem..............Keith

Also check to to see if the flywheels are rubbing against anything as they revolve.
