Ball door ring bolts

[MCSS]

I have a machine where the ball door ring bolts have pulled thru the side frame. What have other people done to fix this? With out replacing the side frame.

Thanks

We only had one machine that had this happen... we made a steel plate to fit it, MIG'ed it on, and ground it smooth.

Re: Ball door ring bolts

I just installed 12 Humpback's and found many holes badly worn and some worn through. I have a high quality 110 volt buzz box. I use 1/16 all position rod and run a bead around the hole, grind flat using a soft pad disk and then using an 82 degree two fluted counter sink. It is fast and easy and the counter sink will not crawl because it has two flutes. The only problem is that you have to be fairly good with a stick arc.

<font size="2" face="Verdana, Helvetica, sans-serif">Dumb question. Is it causing a problem? I've been around PBL's for about 9 years and have seen bolts fall out without causing a problem. I don't mean to sound lazy, but...what would it hurt to run with only 3?

Maybe next year it might only be 2, and the year after that?

<font size="2" face="Verdana, Helvetica, sans-serif">Clutch Plate's answer is a good one. Just make sure it's a 5/16" SAE washer that's thin enough to flex, and to keep it centered as you tighten the cap screw down. Otherwise you might end up with the washer sticking out from the plate enough to damage a ball.

But only 2 bolt's are holding it in place right now.

As far as only 3 bolts, I think that could cause the ball door ring to break prematurely.

Re: Ball door ring bolts

Like I said, it was a dumb question. Good answer about the washer being thin enough to flex. Just make sure it is covered by the fiber plate on the side of the machine.
I had a bolt in one of my machines that someone had slipped an allen wrench in. Marked a lot of balls before I found it. Watch them bolts!!

<font size="2" face="Verdana, Helvetica, sans-serif">Did either of you guys have any problems with the scoring system after zapping the machine with a welder? Just curious, because I was a always taught never to weld on a machine (that has automatic scoring) with anything but gas.

Re: Ball door ring bolts

Good point Triac, I think that most of us are taught that welding on a machine can be harmful to the scoring system.


I have done plenty of welding to AMF &amp; B's with no adverse scoring affects.


Speaking of scoring: I think we were all told to have the steel concentric roller (in place of nylon) to ground the machine. I have no steel rollers and have no scoring probs. Mabye this was for early scoring systems. Sorry I forgot to mension this is on 70's distributors.

Re: Ball door ring bolts

i dont think this is a dumb question, it is right to repair the machine frame and hold the ring in all the provided places, because the ring will fatigue and break prematurley otherwise, but more importently if you leave bolts out YOU HAVE BODGED THE JOB!


an example of what leaving bolts out can do:
i paid someone else to service one of my hire generators as i didnt have time and they left one of the bolts out of the drive flange between diesel engine and main alternator, because of imbalance and other factors the remaining bolts sheared about 2 hours into a show i was being paid a lot of money to do, the guys half-arsed workmanhip cost me the equivalent of $5000 in downtime penalty, just because he didnt put all the bolts back in, he left it sitting on the skidframe!

he got sacked at high speed!
