Hey there everyone.

I am relatively new to the hobby. I picked up a RBION. It looks like the magnetic bolt height was never properly adjusted. I believe it should be sitting flush. Anyways as a result, it has mushroomed. I'd like to remove the bolt, coming out the play field side and grind it down. However underneath it is held by a nut. I'm assuming you simply turn the nut counter clock wise but it will not break loose. I mean I can get it off, but I'm afraid I may break something or crack the play field. Any suggestions would be greatly appreciated.

Thanks in advance.

You should be able to loosen the nut, and then use a screw driver to turn the core clockwise and remove it through the top side of the playfield. That nut can get pretty stuck sometimes, so you may need a lot of torque.

Huge screwdriver and pliers on it for extra torque.

Thanks for the replies. Can too much torque cause anything else to break?

Update: Got it. Heard nothing cracking so I kept going till it broke loose.

Thanks again everyone.

They probably use loctite. You can get a new magnet core very cheaply. Might as well since your game is apart.

I have always had good luck heating the nut with a mapp gas torch or lighter for the stubborn magnets, being very careful not to burn anything around it.

^^^ + 1 on heat^^^....A little late to the game, but a hair dryer works great also....heat/turn/heat turn etc. if badly mushroomed take out from the top.

May not work flush ! Mine sticks up so does all the ones I've seen . Factory adjust all of them wrong ? After the mag. stops the ball - it needs to roll off - then the mag. flips it back .

TenaciousT mine doesn't flip ball back, is it the coil or something else? it grabs it strong for a second, but instead of the second pulse flipping it to the back, it just drops and heads to the centre of flippers?
