[SOLVED] Pivot was gummed up with old grease. Cleaned pivot.

Short version: Outhole coil buzzes while trying to pop and plunger is very stiff. Will not eject ball to trough.

Fired up TZ after a few years. Ran tests and all seemed fine so I tried a game. The powerball was first out and was recognized. Shot it around a bit and as soon as it passed the flippers, the game could not find any balls and stayed in 'Give it back' mode and would periodically pop around the machine to find a ball.

In test mode found the outhole coil does not fire, only buzzes repeatedly. I can push the plunger but it's stiff (with machine turned on). If I push it out it does pop the ball just a bit. There is a bit of residue by the coil and it also appears to have been replaced at some point.

The powerball is still in the outhole position with one regular ball in the trough.

Any advice much appreciated.

The pivot was badly gummed up with old grease. Got it cleaned out and everything moves freely now.

What kind of grease (if any) should I use on the pivot to put it back?
