Removing Flywheel from Motor

[andylvtrains]

Hi:

I need to remove the flywheel from an Atlas HO motor to change the engine mount.  Is there a way to do it wothout damaging the motor?

Thanks

You need a gear puller.  Walthers carries one made by Northwest Short Line called the Puller II that you might want to check out.

Hope this helps.

I have used the NWSL Puller for pulling flywheels, gears and drivers. Very good device.

I have a similar gear extractor from Micromark.  However there is not enough room between the motorcase and the gear to insert the puller between the two.  How do extract the flywheel then?

Thanks

Place a good hose clamp on the flywheel and crank it down then clamp the flywheel in a vise, the pipe clamp protects and holds the flywheel then gently use a pin punch to tap the motor shaft, if it goes easy just tap it all the way out otherwise just tap it until you have clearance for the puller.

I forgot to mention that. Happened to me with one loco. Just be careful so you do not bend the motor shaft.
I use a vise with rubber jaw attachments.
