  • Honey...I'll be back in an hour....

    Last Saturday 1 PM, it was my day off, sun was shining mhhhh getting ready for a nice day on my terrace(had enough of coffee and knew a lot of cold beers were waiting for me).....
    Pring pring...(telephone ringing on my day off makes me nervous, most of the times it's family or friends but you always think "oh no not the bowling")..
    I saw on the display it was the bowling indeed(at this saturday a new guy is working with only one month experience so I hoped it would be something not to bad)....
    "hey Martin I've got a problem with a BE motor, it's getting hot and the carpet won't move either, the evening mechanic did try three other stators already"(I forbid to change BE stators only because we have to much different BE motors; GE, Westinghouse long and short ankers, Nationals(also different types), 60 HZ and 50 Hz and ofcourse all of them LH and RH)..
    "I did change the complete gearbox plus the stator like you told me,it was the last one I could find"(we allways have 3 complete RH and 3 Lh ready}"but it's still running too hot and the carpet won't move..."
    I did put my unopened beer back in the fridge and said my wife I had to go to my work and would be back in an hour or so.
    WRONG, WRONG, WRONG!!!!!!!!!!!!!!
    Oops the wheather is getting to bad now with a lot of thunder, I have to shut my computer down for some time....I'm affraid something goes wrong ...will be continued..
    We haven't had rain for about three months and now we have the whole bunch at once, the thunder sounds less hard so I can continiou(lost a computer in a thunderstorm once too much).

    "WRONG..." that's where I left.

    Came in the bowling and went to the 'office'and saw 5 BE motors standing there ripped to the bone, said "aw my god" and went to lane 13(?)where I found our new pinchaser with question marks and clouds above his head.
    "I did my best but I'm realy lost now"he said.
    I saw the "half moon"bearing retainer was broken and the shaft of the rear roller was GRRRGRRiinging in the side plate, at this moment I knew my "sunny afternoon" was gone.
    I also saw the cushion plank was broken and the plows were loose and the ball door was broken(they all could have survived till monday but I decided he could learn something from this so we did go all the way).
    We took out the front roller ,rear roller, bounce plate,carpet, balldoor, plow, cushion plank etc.
    We cleaned the place and I wanted to show him how dangerous the front bearing assy's are by removing one of the carpet removing pins, after removing it itstead of banging against the tail plank it stayed on the same position..., No movement possible on that thing (the new mechanic started to look at me..."is he kidding me????"
    I tried the grease "gun"on it but nothing came through, so I tried to get it of.. I did get it of, but also the pivot stud broke of*&^%$#$%%^&^%, my new mechanic nows nothing about welding but he knows how to use a mirror and bend a welding stick 180 degrees now.
    Well, got that thing going again, after reading somebody did get the spring on by hand I did give it a try too and it is actualy easy(if the bounce plate is gone try this out for fun once). Luckaly the small plow was broken and already removed so the acces to the the broken half moon bearing support was easyer already so I just needed to grind the old welded one of and bold a new one on.
    After renewing the worm gear and the clutch plate (broken and bended thanks to a motor running the wrong side before)The machine did run again.. but the sun was gone and it's raining all day now, so be carefull with lane 13.

    Hope I didn't bore you

    So it goes.

          Bolt on pivit stud and a Stahl's front roller bracket removal tool , a must for any serious technicians tool box.

          My question is, has anyone ever had a bolt on pivit stud fail, snap off, etc..

          Almost forgot Lampie, better you then me. :p

          Haha just kidding Lampie. Anytime I start a new center I try to go through all the pits in 90-120 days. We all know that this area is avoided like the plague by 90% of staffed center mechanics.

          The machines I have now are getting some years on them and the half moon bearing supports for the rear rollers are getting fatigued enough to collapse at any given time. If you have older machines I would think about replacing them.

          For now, the easiest thing to do is pull the plows and mat, apron. Just pin the front roller and pull the rear roller. wrap a sizable bungy cord around the bounce plate to hold the carpet out of your way.

          The best thing to do is to first center punch and drill out the two exposed holes on the old retainer. Now, if you have a torch, cut off as much of the old retainer as possible then grind off flush, treat the steel with a primer (paint if prefer), bolt on the new bearing support retainer and drill out the remaining two holes.

          If you do not have a torch, block off as must area as possible to keep your grindings off the machine, pbl, and also from going out onto the lane area.

          The lenght of your bolts is critical, too long and which way they face is up to you. There are different ways to look at this.

          I like to have two stove bolts in the carpet drive pulleys, therefore, if I have to I will face the bolts from inside the ball lift area, two long and they'll turn a carpet edge to shreds. The only detriment to this direction is that you cannot get flat washers on the retainer side without grinding them.

          Well I have babbled long enough. Now I'm boring Lampie. [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

            Dear Mr. Felix an dear Mr. Mike; I know these studs are x-isting(?) I even have them, but only having one hour left before the machine(s)were needed again and having a lot of welding mess at the other side of the machine plate(plus not knowing what was wrong-more than I knew at that moment-)made me decide to reweld the broken pivod stud.
            Boringyou yours,
            So it goes.

              Martin, there is nothing wrong with welding the old on back on. I'm sure it is just temporary anyway and you are going to fix it properly another time.

              Been there, no fun. Just thought since we were talking about metal fatigue and/or failure, I would hit on the rear roller bearing support.

              Take it easy.
