Thanks again for this thread Vid! I utilized it on Motordome to take the three bumpers apart, replace what needed to be replaced, and then put them back together correctly.
It's too grotesque to post a picture off, but I found one of the pops had its "Big Spring" rolled over in on itself. It was actually partially trapped in the yokes/plunger. It's as bad as it sounds
All is well now, though!
Thank you again for taking the time to document the Bally 80’s pop bumper rebuild section... It's much appreciated and utilized!
