Usually you need to remove the center rail pickup roller. I forget if the screw is top down, or bottom up. Take note of any spacers and plastic washers that fall out! You need to get them back in the correct places to prevent an internal short. Then there should be a screw in the bottom of the truck block. Take that out and then motor and truck should separate. That will allow access to your screws. BTW, now is a great time to replace the traction tires! Assembly is the reverse.

Thanks. I’ll give that a try. 

lehighline,  thanks again.  Your suggestion worked.  Screw was from the inside top down with wire connector.  All put back together and working fine.  If you look at picture, you will note a critical piece is missing.  I carelessly broke off the horn.  I reglued it back on without problem but pretty stupid of me. Anyway, back in operation, many thanks to you. Regards.
