One of my pins I just got up and running was playing well until after a quite a few games. Then I noticed the right hand flipper acting sluggish and sticking.

I readjusted the flipper. No help.

I swapped in a new sleeve. Still no help.

Finally, I removed the plunger and link.

I have not heard anyone talk of this problem before. It is something else to file away in the knowledge base.

The problem: The flipper link is binding on the roll pin. I put a drop of super lube on and the problem went away---for awhile. It is sticking again so I will be replacing either the link, or the roll pin, or the link, or roll pin assembly.

Yeah, I know. It was not something I expecting to have to look for. When the old "stick in a new sleeve" failed to correct the problem I had to look deeper. Once I pulled the plunger/link assembly I could feel the problem.

After I had hit the roll pin with some super lube, the pin played very well for about 50 short-ball-time games. I guess the lube wore out or dried up because I am seized up again.

I going to have to drive the pin out. Right now, I don't know if the pin is too large of diameter or if the hole in the link is undersized.

So now you know. If a new sleeve does not correct the problem, this rare issue might be what ails you.
