I just rebuilt the flippers on one of my games last weekend and came upon something weird. The coils are standard FL11630s. Blue wrappers. OEM coils. When I tried to put new coil sleeves in them, the sleeves were too tight to fit in the coils. These are new sleeves from Pinball life and I know I have used them before with no problems. Of course the first thought is that the coils must have overheated and warped at some point. But they did not look like they every overheated. I had about 12 new sleeves and they were all too tight for either coil.
So I have some new coils on hand and was going to replace them. I noticed the new coils had sleeves already in them. Just on a chance I slid the sleeve out of the new coil and tried it in the old coil - surprise, it slid right in. What the heck is going on here. Have the sleeve outside diameters changed? I looked closely and the new sleeves do appear to be made of slightly thicker material.
Anyone else run into this?
