Do not install any mod with the machine turned on.
The pictures show the process, but heres a overal description in this order.
Remove playfield glass.
Raise and pull out playfield to rest on the secured rubber feet.
Unplug the two spot light wiring plugs from the board in pictures.
Remove the 2 lower apron panel screws, carefully push it forward and remove and set to the side.
Remove the pictured nuts on the right channel rail.
Leave the 3 included screws assembled as the shipped. Insert and slide one of the screws that has 4 nuts on it. Then install the nut with 3 screws on it followed by the other screw with 4 nuts.
*****( Jersey Jack has those studs custom made for their channel and only in that size. That size is not available anywhere.. The included screws heads are wide enough to use as installation screws)*****
Slide the 3 screws into place close to the picture. Finger tighten them into place only using the lowest nut. Then run the others down to make contact with that tightened nut. Remove the top nut and 1 washer from each of the new screws.
Unbolt the right wireform at sling post and center stud. You do not need to unbolt the 2 small screws at kaboom ramp or remove the rail switch. You need to pull the other wireform out of the left side of machine and lay to the side. The wireform can be lifted up enough to install everything.
Lift the front of the wireform slightly and curl the head support under it. Once its under and roughly in placd install the screw into the headsupport washer hole and into the wireform hole that holds tbe left wireform. Do not tighten it. Just start it enough to hold it on wireform.
With the wireform loose take the slinky and seperate (spread apart) the very first coil to form a “c”. Then start with the first coil and turn the slinky in your hand while guiding the coil around the wireform. It is very easy to do and take your time coiling it over the wireform. After it is around wireform on both ends of slinky just leave it loose and towards the front of wireform.
Install the tail section and foot section together in one step. You will need the wireform to be raised slightly as you do that. Once both are on the studs, place the removed washer and nuts back on the screws. Lower the wireform down and postion the center spine of the tail so its lined up with rail. And you might move the feet around to a desired position. Once those are in place tighten the lowest nut.
*****Do not over tighten the lowest nut. It just needs to be snug. You can hold the screw threads above and tighten the nut. If you need to you can use two wrenches and lock the upper two nuts in place and then tighten lower nut. You should not have to do that. I have held the screw threads and tightened the nut…*******************
After the lowest nut is secured work the remaining ones down to that one working your way up. Start from the bottom, tighten the next one up and then the next….
Once the tail section is in place and tightened slide the slinky over the spine. If needed put small pressure on the spine downward to get the slinky down it towards the tail..
The new screw that holds the head rear support arm also holds the spine support. Let the wireform rest on the sling stud roughly into place and make sure the head will be in place at those 2 mounting points. Slide the stud as needed and lock into place in the same manner as tail section screws.
Have the head over that screw first making sure there is a washer under it. Then install the spine support with the larger washer going over the screw and the smaller one on to the spine. You will need to apply a small amount of pressure downward to get the support arm over the spine. Once in position as seen in photos, place the removed washer and nut back on to screw and tighten it. Again. Snug is good.
Check ball clearance by rolling a ball below that small washer on arm. Only check this when its tightened completely. If the ball hits all you need to do is adjust it with a washer or turning the nuts to adjust it. I put everything on my game prior, so it should be good.
At this point you need to reinstall the left wireform. Looking at the right wireform mounting screw you want it to be stacked as shown. Right rail, left rail, washer then slink mount. And you reinstall the right wireform mid point screw.
Install the head as shown starting at the right head side mounting hole. Feed the wireform into the right hole and then through the head. Take your time and push it slowly into the head while looking at the left side of the head hole you will see the wireform. Get it through the head completely and then through the other support. Once in place push the chin bar so that it is under slinks chin. Let it hang an look at the chin bars centerline. It needs to be in the middle if the two ball traveling rails. Once that is lined up take one of the removed lock washers and push it over the wireform towards the support arm. That lock washer should not be against the support washer only next to it to keep the head into place. It will make sense when you do it. Either with pliers or I use a small socket that is smaller than the washer and hold the other side of support and push into place.
Launch a few balls and verify the ball clears spine washer and the head pivots.
Reinstall apron panel, 2 screws ensuring the apron is engaged with sliding locks on playfield. They insert into cut outs. Then plug the spotlights back in.
