I am restoring a 1970 Schwinn Suburban and I am at a loss when it comes to removing this bottom bracket. The crank arms do not come off normally (no way to use a crank puller) and they won’t unscrew. I have put some lube on the side opposite the drivetrain and maybe I need to wack it with a mallet but any advice would be greatly appreciated!!
