Can someone help me with two part numbers for a High Hand? I broke the shoulder bolt on the ball count unit. I just got it and don’t have a manual yet.

I’d also like to order one for the credit unit since that needs to come apart to and will probably break. I’m not sure if they are the same or not.

Thanks!!

I found it. Looks like the ball count unit is the A1059 and the credit unit is A1058. Maybe the correct term is shoulder screw and I said bolt?

Spyderturbo007, It looks like the nut is still on the broken screw in your first photo. If you don't remove the nut from the back side before turning the shoulder screw, you'll break it every time.

...and, Gottlieb used something like loctite in those parts. The only reliable way to remove them is via heat.

I broke mine from an Abra Ca Dabra bonus unit.

Marcos has a similar part but the threads aren’t long enough and you can’t get the nut on it.

Waiting for a bigger order for PBR.

It is. I was actually trying to take the nut off when it snapped.

This is my first experience with shoulder bolts. It appears as though they aren’t supposed to be tight? Even with a little bit of Teflon lube, when I tighten them the arms don’t move.

Looks like I get it to where things can still pivot and then lock it down with the nut. Is that right?

100% correct.

Yep, This is the reason why I rarely take them apart anymore. I have freed some up that seemed like they were welded on without removing that screw. I use synthetic Super Lube to soften and get it moving. Followed by a solvent like 91% alcohol or mineral spirits. I liberally flow the solvent on and scrub it with a toothbrush until all the old grease breaks down and is removed and it pivots easily. Then I add one drop of super lube where they originally put that grease. I did some like this over 20 years ago (some with and some without the extra drop of oil) and they all still move freely.

Other sticky pivots that just require removal of a pin or clip I still disassemble to clean, but these just aren't worth the risk. If I couldn't free them up I would still take them apart, but I haven't found that necessary, so far.

Hey there! Got a moment?
