Hi - pickup up a 1975 Bally knockout tomorrow and was wondering if anyone could help me understand how to remove the head? Ive never moved an EM before. 4 bolts on the inside and uplug connectors?

any help would be appreciated so I get be prepared for the pickup. Thanks

Thanks all - Ive not dealt with a machine with a back door on the backbox. I assume this is opened in the back by a key? If no key available anything to watch out for if drilling it out? Ive moved several Gottlieb System 1's with lock on side but the door swings out toward the playfield.

Bad idea to use a dolly to move the backbox? It will unfortunately only be me on the pickup

One last question - remove backglass? or ok to transport with it in the back box?>

Cool thanks guys I hope I have the right tools when Im there sounds pretty straight forward.

Wow this is so much more than what I expected to get from this thread - great stuff thanks a ton. Its coming out of a basement and through 50 ish degree Ohio weather to the car. 25 min drive home

Good call on the drywall screw. I posted this to make sure I had everything covered I feel like i do now.

Couple weeks ago I went to grab a DE machine and had everything but that damn Allen wrench. Almost lost the deal cause I couldn't take it that day.

Successful grab! Thanks

Haven't turned it on yet need to figure out what to look for on these EMs before turning on.

Ok check coils if locked. What about cleaning the Jones plug?

I had thought about just manually moving any moving parts so make sure they aren't restricted. Thanks for help.

I have keys for back

Thanks was just looking for general direction I know plenty of info out there. Ill report back.

Yeah sounds like good advice I have experience with newer pins but ZERO on EMs
