Model Railroading > Flywheel Removal

I am replacing the very weak motor in a Bowser C430.  I need to find a comparable replacement motor, but the flywheels are very tightly fit onto the old motor.  What is the best way to remove these flywheels as I want to use them on the new motor.  Any help appreciated.

Put a grip on both flywheels then twist and pull until you pull one off. Then put a vise grip pliers on the bare motor shaft and your hand on the flywheel so you can pull and twist until last flywheel comes off.

I have used a soldering iron that I place on the end of the flywheel for a few moments. This will let the flywheel expand just enough to remove it from the shaft of the old motor without causing any damage to the flywheel ie. gouges etc. Hope this helps.

NWSL made a "puller" that would do that job easier and without harm to the motor shaft.

Also by clamping the flywheel with something it can be distorted enough so its harder to remove. Brass is soft and easliy distorted with something like vise grips. That would be the last way I would try and have much experiance in removing things being a retired mechanic.
 

A few comments. 

Those motors are junk for sure and very weak. Bowser did come out with a better motor but it is not amazing but definitely an improvement. You can order them direct from Bowser for $30@ plus shipping. Just email them and they will tell you which one. I just replaced 2 C636's with new Bowser motors and it was quite easy. They come with flywheels attached. I would be careful to not remove any flywheels without a flywheel remover and it be frank, those flywheels may not fit the new motor shaft and you have to balance them also. It's not black and white.  There is a guy on Ebay that sells some and they appear to be good based on Ebay feedback. In my opinion, getting replacement motors from Bowser is the best choice. Drop in and easy. Bruce

I never said to clamp the flywheel with anything but a bare hand. If that is going to gouge the brass flywheel then I don't want to shake your hand.

The pliers grip on the motor shaft is no big deal account the motor is headed to the trash bin.

Doesn't anyone read the whole thread anymore?

It was unclear as to what you were using to grip it had to be more than your hand. Later in  your statement you said vise grips  made it sound like that was used to grip it. OK now thats why OK????

Well, you did use TWO sentences.
