Quoted from WizardsCastle:I installed it, and first thing I noticed was that the crank shaft almost seemed to small/tight for the flippers bats. I had to really work it in, twisting to get it to slide into place.
That's normal. Design issue, not the wrong part. And not necessarily a bad thing. Once replaced, it shouldn't need attention for several thousand plays. Tight start is ok.
How so? Once you have the right up and down play (about a credit card's thickness), snug it tight with the flipper positioned higher than it should be. Then push bat down to align with alignment hole.
****** IMPORTANT PART******
Once aligned with the alignment hole, raise the flipper slightly before tightening. If you try to tighten with the flipper in the resting position, torque will take it out of alignment as you tighten. It a weird physics thing. Raise the flipper slightly with one hand, then tighten. Also, if your bat shafts are chewed from previous tightening, that can make alignment harder.
Pinball Life has been the go to source for flipper rebuild kits forever. Coincidentally, they've also have had far and away the best LOTR mod forever, which you absolutely should get if you don't have them. Original flipper coils tended to fade after 20 minutes, couldn't shoot the ring. Upgraded 'special' coils have same part number as factory coil, much stronger. Installing them, then increasing pitch on the game to ~7 degrees takes the game to another level.
