Ok, so after someone's email, I had to go and open up my NYC F3s and investigate if my aforementioned technique would work, and it did!
All I had to do is:
- Remove the screws from the truck retaining ring
- Drop the truck
- Remove the steps from the truck (replace the removed screws with a 3mm flat machine screw instead of the removed pan head)
- Re-insert the truck
- Slide the lock washer in under the retaining ring
- Re-insert the 3mm pan head screws
And voila! A lowered Lionel TMCC NYC F3, that now matches the height of Atlas F2... Here's some pics of it nose-to-nose with the Atlas, and back to back with the already lowered Lionel F3 B unit.
Thanks,
Mario
