  • Ball lift and sweep squealing

    OK in this small town we had our big six game travel league today. So last night we had some lanes go down and it continued through today.

    1st a couple of weeks ago we had a sweep that would squeal on the way down to 33. I thought it may be the gear box so I chaned that and the noise stopped for a couple of weeks. In the second game of this event the noise was back. I tried all day and could never find what it was. Any ideas. I thought it was the teliscoping shock, Wrong! It sounds like it may be comming from somewhare in the drive shaft. Any ideas?

    Here is the hard one. In the last frame of our Jr. leagues Sat. Lane 10 started squealing. I was able to trace it to the clutch assembly on the lane 10 side. I put new parts in for the clutch. This also quieted the ball lift down. Low and behold in game 4 of today it was back!. When I relax the carpet drive belt for lane 10 the noise would quit. Then I would engage it for a second or two to get the ball back and the pins in the pin wheel. After two hours of this in the 8th frame of the last game the noise quit.

    As I get the dynamite ready for these two lanes I thought I would ask you guys here if you had any ideas before I light the fuse.

    Thanks in advance for the help.

    Thanks guys.

    Re: Ball lift and sweep squealing

    I'm not sure about the sweep squeak as I am not that experienced in 70's sweeps. But as for your squeak on lane 10, it could be in your ball lift bearings or clutch (but since you put new clutch parts in, it's probably not). Since the sound disappeared when you disengaged your carpet drive pulley, I would check your front roller bearings and hinges. They might be getting dry. Also check your rear roller bearings and your front roller brackets. Give everything a good lubricating and see if the squeak goes away. If not, at least you have one less machine to lubricate.

      Well, Pat, it sound like it's time to put some WD40 in a bug sprayer and give them both a goo spray-down! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] (Just kiddin')

      Sometimes the sweep squeak on 0-to-66 can be in one of the pillow blocks or the main self-aligning bearing on the 1699 shaft. Try sraying a little WD40 onto the bearing.

      As far as your ball lift is concerned, could it possibly be the tensioner pulley? Sometimes it's not even the bearing in that pulley, but just the edge of the carpet drive belt rubbing up against the flange of it.

      Give everyone earplugs! :p

        Is the ball lift shaft rubbing the side plate of the machine?

          before you go tearing up the tail end of the machine, take a look at your filler pad. It has two little rubber bumpers that the kicker stops sit against. If the filler pad loosens and moves left or right too far, the rubber bumpers will squeal like a banshee against the kicker wheel shaft.

          Very common problem.. to locate something like this, turn off 1 pit at a time until the squealing stops. Once you find the side that is making the noise, to verify if it is this problem, press down firmly on the belt tensioner arm for the kicker (where the springs attach). This will ease up the tension on the kicker and stop the squeal, or it will change pitch.

          To repair it, drop the kicker springs, remove the paddle, loosen the filler pad mounting bolts, re-center it, tighten, put the paddle and kicker springs back on, and test for proper operation.

          We've notched a flat spot into the rubber bumpers to allow for more adjustment without causing squeal, since some of our tail ends were not installed the correct distance apart.

            Jerry's right, and if you do not get into it soon your rear roller shaft will be cut through. You'll get a ball call go down there and see your rear roller sheave lying on the ground.

            As far as the sweep goes, a lub job should take care of its squeek.

              When I had kickers....I super glued the bumpers to the kicker housing.

                Thanks for the advise on everything. For the sweep I was going to start with the pillow block. Thanks for the idea.

                For the ball lift I am pretty sure that it is the clutch and not the roller bearings. That is a good idea to check. I sat in this for over two hours and I am 99% sure that I have located the problem is in the clutch. To be sure I will trace it further. I think that I am just going to replace the whole shaft and the asemblies with it.

                Thanks guys I will reply tonight after I light the fuse or fix this stuff.

                I don't know the bug sprayer filled with wd40, hmmmmm maybe we could kill two birds with one stone. I am wondering how well does wd40 hold a lane pattern? [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

                  Re: Ball lift and sweep squealing

                  OK guys here we go. I told you I would write and tell you what I found.

                  First the sweep. We have older machines that have two 000-021-743 / 734 bearings on the sweep drive shaft. The bearing closest to the gearbox was what was squealing. I am going to convert it to only having one bearing. I have been doing this on our table drive shafts if we break a drive shaft.

                  Next is lane ten. It was is a roller bearing. Does crow taste like chicken???? The roller bearing on the ball lift side is going out and not sitting in its seat correctly. So the roller is being pushed to the opposite side and the common side bearing is rubbing on the machine. You know this has to be on the side of the house that has a wall right next to the machine. So to get the shaft out I need to pull the pit and take the roller through lane 9. The dynamite is starting to look good right now [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

                  I am going to bed now. Have a great day all.

[img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] pat...I'm guessing it's the rear roller you are talking about. I thought you have to pull the pit whether there was a wall there or not? [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] Even if there wasn't a wall so close to the machine, how would you hammer a new bearing on? [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] Maybe I'm thinking way off line here? Anyway...Good Luck! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

                        King you have helped me out a lot!!

                        Louie, Your right it is the rear roller. usually I can slide it under the carpet of the lane next to where I need to get the roller out.

                        Thanks for the help guys. [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

                          Jerry, you may have to adjust your scorecard. Pat does not have the pit apart yet so he has,t done a thorough inspection.

                          My reply was right on the target area and the noise pat was hearing I doubt was the bearing. The noise was the shaft against the machine wall or the shaft against the welded bearing support bracket.

                          I have great hearing and could recognize Pat's post as a grind and not a squeal. [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

                            Mike you are right! The bearing is out on the ball door side and pushing the roller to the common side so the bearing and shaft are gringing on the side of the machine.

                            I am glad that you have good hearing. I think that my hearing is gone after having my head in that machine for so long! [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]
