The plug has an "8" adjacent to one corner.  Is that the orange wire connection??

I have an old version (non-spectrum) Pennsy 4-4-0 with very brittle plastic valve guides..and one snapped.  Is there any way I can get the metal guides that I have on my other Bman 4-4-0 and then install in place of the plastic ones?

A fellow club member has an "old" BMAN diesel with an "Athearn Like Motor" that has two flywheels.  I cannot "twist off" the flywheels as I can easily do on Athearn motors.  We need to take the motor apart to try and tune up this engine.  Does Bachman use an adhesive on their flywheels that I will have to "break" to take off the flywheels? 

I think the motor is unbalanced as it vibrates a bit much for my liking.  So we need to either fix that or try another motor.
