I have been restoring several Lionel Alco FA engines. I am perplexed on how to remove the truck frame from the top plate assembly. It looks like there are 4 tabs from the truck frame that poke through the top plate, I could try a screw driver as a wedge below and pop it off, not sure how the process to reattach it would work. Thanks in advance for any help.
Here is the picture of the 8010-100 motor truck from the Service Manual Supplement #1

This is the shell, all clean!
