Hello folks, I'm new here and came for advice since your community seems resourceful.

So yeah, I have a Schwinn Suspend mountain bike and I'm trying to remove my crank set to repair the bottom bracket (bearing separator is destroyed). I've managed to remove the left pedal from the BB with no problems using a crank puller. The right side though doesn't want to move at all. It's a regular square taper BB and looking at it there's nothing that should be preventing it from being removed. I've applied a huge amount of force on the crank puller and tried using wd40, but to no avail - all I managed to do is slightly bend the crank puller (which is hardened steel, so it gives you an idea on how much torque I applied). I tried working with a hammer and a metal rod from the back of the crank while applying pressure with the crank puller, but it doesn't want to move at all.

At that point I'm out of ideas.
Thanks in advance.
