Quoted from Tommy-dog:My shooter rod has a lot of wobble in the white beehive housing. On my other games there is a sleeve bushing in the housing. I tried to add one but it would not fit.
Mine also had some looseness to it, so I replaced the beehive with one from Pinball Life: Product ID: 4A-115-W, Beehive Shooter Housing - White.
I took the shooter assembly off the game and used a caliper to measure some dimensions. It's difficult to measure inside holes, especially in plastic, so I used some drill bits to help out.
Shooter Rod: 0.376" OD
Current Beehive: ~0.383" ID
New Beehive: ~0.371" or 0.372" (clear through) About 0.375" each end
The Beehives have a front and a back. I found the holes in both the new and the old have offset centerlines. A drill bit would go into each end, but would not traverse through the other side's hole.
So, the shooter rod wouldn't work with the new Beehive, without some enlarging and straightening the holes in that Beehive.
I ran a 3/8 bit through the plastic and tried the rod again. It barely went through (both holes) and had way too much friction to work properly. I tried reaming it again with similar friction related results.
I checked and the next bit diameter was 25/64 or about 0.390", so too big to use.
So I tried lapping the hole in the Beehive, with the shooter rod and some grit. The only grit I could find was Comet.

So, I chucked the end of the shooter rod in a drill motor, got the rod wet and sprinkled on some comet on the wet rod. I then started the drill motor and moved the beehive up and down the rod. I did this 3 times, then took the setup apart and cleaned everything really well to get off any comet.
This method left a lot of very fine scratches on the rod, they didn't seem to cause any issues but wanted to let you know what I found.
After I cleaned everything up (water, alcohol and paper towels) I sprayed a bit of silicone on the rod and the rod moved freely in the Beehive. A little friction, but what one would expect on a tight fitting assembly. The return spring would have no difficulty in resetting the rod after release.
Then I put the new Beehive back into the game. Remember, the Beehive's through hole is at an angle, be sure to install it so that the rod points up slightly...not down slightly.
The holes in the new Beehive were very tight for the screws, I couldn't get the screws to bottom out and secure the metal plate inside the cabinet...even after I drilled out the holes with a 3/32 bit. So, I ended up putting the 4 spacers on 1 screw and finding another spacer in my box of parts for the other screw. If the assembly becomes loose later, I'll have to go in and rethink the spacer sizes.
One reason that people may have issues with getting the shooter rod assembly aligned correctly is that on my machine the ground braid is under the metal bracket on the inside of the cabinet. This really hoses up the reassembly.
I may have damaged one of the 2 led's (1 above and 1 below the metal bracket. The Beehive lights up before I launch a ball, but goes out after I shoot. It doesn't light up again until I need to shoot a ball again. Someone may have to help me on this, please.
So now my shooter rod has repeatable friction so I can try for a skill shot and it has no excessive wobble to it.
