I need to find a screw that holds the drive wheel (front right) to the axle. I bought loco at estate auction and discovered it when I tested the loco at home. Where can one find these?
 
Thanks Greg, I went to a R/C Hobby Shop today and found some. They measured the thread count and size. I ended up with 6 black button head hex drive screws 3 x 6 mm for a grand total of a dollar. Not sure if they are stainless tho. Can I use a mild loctite on these to prevent them from backing out?.
 
Yes, but your issue with the Aristo steamers goes deeper, it's the tapered fit and lack of keyway combined with a high torque motor.

I would suggest lapping the wheels to the axles to better the fit.

Make sure you have the star washers in place.

Make sure that the screw tightens the star washer which then tightens on the recess in the wheel, NOT on the axle end.

Loctite is not the answer, but it cannot hurt.

Please read the section on "Axle Slippage" on the following page: https://elmassian.com/index.php?option=com_content&view=article&id=215&Itemid=248

This is a complicated issue, but can be solved. If your loco slips a wheel, it is EASY for it to destroy gearboxes and rod gear.
