The VUK in the upper right corner of my TFTC is experiencing sporadic issues kicking the ball back up to the playfield. Sometimes it kicks the ball up on the first try without any problems and other times it takes 2, 3, 4, 5, 6 times or so until it is successful in kicking the ball up to the playfield.
Upon further inspection of the VUK/Coil assembly under the playfield there is quite a bit of slop when I wiggle the ball popper cap. I have attached photos of this VUK assembly below.
On the VUK assembly there are only two compression rings when the manual calls for 3 compression rings for this assembly. I am guessing that this may be the cause of the extra slop in the assembly.
I have ordered the following VUK component kit from Marco Specialties as it appears to have everything that I need to re-build this VUK on my TFTC.
This kit also has 3 compression rings. I also checked the VUK on my JP which works basically 100 percent of the time and it too has 3 compression rings.
Do I need any type of special tool when installing the compression rings around the plastic ball popper cap to ensure that it is nice and snug and that everything works as it should?
