installing pre war wheel gears

There is not enough material to hold the gear on if it is pressed on?  I am generally just pressing the gears on to my American Flyer wheels and that is enough.

I did the same repair on a 248 motor, and used JB Weld to secure the gears.  Works perfectly.

If you are using the MEW wheels, tapping the gear down flat on the wheel, using a ratchet socket, there is plenty of room to "peen over" the 4 corners of the gear hub w/ a flat punch to attach the gear firmly.

 I have not used either of the other 2 importers of the same wheel to compare.  Just wanted to set the record straight.  Harry 

It is very important to make sure that there is no casting flash or anything else causing an uneven surface which would prevent the gear from fully seating. A little work with a file will assure a flat surface. In over 50 years, I have never had to resort to the use of glue. Follow Harry's instructions. Good luck!

I filed the flash off the wheel and got the gear to lay flat.what I see though is that the corners of the new gear are sort of rounded out making for less space to peen the corners of the boss down.I will try and send a picture tomorrow.

Hi alright I am going to try to post photos(not very good at this stuff.In one photo I have an old gear and a new gear for comparison,if you look at the corners of the new gear you can see it is rounded out.I am afraid that this will take away from the amount of material that holds the gear to the wheel.

Considering the rounded holes in the corners of the replacement gear, the JB Weld is your best solution.  As I posted above, I did a gear/wheel replacement on a 248 motor, and it works perfectly.
