Jonny five said "No disassemble" oh yes I do!

I looked high and low for any thread on opening up a Bachmann G Heisler for battery/radio control conversion but nada zilch that I could find. Maybe I need new eyes as my glasses are fine… I converted a few Bachmann Shay-Climax but never a Heisler. Anyone or all know where there might be an answer ?
I read pictures very well hehe …

Cheers,
