2020 Drive Gear replacement question

Welcome to the forum.

I've never done this myself, but I've always heard that a wheel puller is always recommended.

BTW, in regards to your avatar, looks like you're inside an anechoic chamber.

lol, yes.  I'm a voice actor by trade.  That was shot in my studio.

You will need to remove the middle drivers that are closest to the rear wheel set before you can remove the rear wheel set.

You may want to consider replacing the axle bearings while you have it apart.

This work is best done with a wheel puller to remove the wheels, and an arbor press with wheels cups to remount them.

Welcome to the forum!

As has been stated, a wheel puller is is used to remove the wheels properly without damaging them, the axle, or locomotive frame. Reassembling the wheels and quartering them really needs a proper press with wheel cups. A press does not come cheap. The procedures necessary to do the repair can be done without the proper equipment if you are handy and innovative. A trip to your local Lionel repair shop would be recommended if you are not sure, or you want the job done properly.
