  • PBL

    What the hell is that mess of #$@%^#@! that makes up the light ball sensor? I have very little to no knowledge of the PBL but I picked up a 70 center (4 lanes) and on the low end...LOL...lane two, the LBS fights the light balls on the even lane. What should I look out for?

    Just to clarify my feelings on the PBL it seems like a pretty decent piece of equipment but the LBS seems like over kill....JMO

    Re: PBL

    Hey ED
    I said that along time ago. Only my statement was it's like driving a Indy car to a grocery store. Rip them out & throw them in the trash. Reduction pulley's on old fashion paddles work just super.

      Re: PBL

      I have a mod that will allow you to apply enough strength to the paddle to kick out 2 16 lb balls + a pin, but is slow enough (and hesitates on each side long enough) for the 6 lb'ers to get back in the door before the paddel moves again. If you are interested, private me, and I will describe it.

        You'd think the LBS is something a Brunswick engineer would design. :p

        They are a bit overkill. But when they are adjusted right they're great.

          I had 2 pairs with LBS's and was having all kinds of problems. Bought a couple of mini PBL's from vantage and won't ever put back LBS's.

            I have found the LBS are a nightmare to adjust and set up correctly, Ours just push the 6 & 7lb balls back out onto the Carpet. if anyone can invent an easy solution we would be very intrested.

              The LBS does work very well if you know how to use them up here in alaska that is all that the 70 centers have. one thing that works very well is to put c clips underneith the trip cams to strenthen up the trip cam. if there not there it lets the trip cam movee back to where it was before it triped.
              They say that the **** rolls down hill but the smell always starts at the top.

                Charlie the PBL is a very simple mechanical operation. I don't want to sound like BEBOP (who has no trouble with anything) but the best way to learn the operation of the LBS is to take the whole unit paddle and all, put it in your vice (clamp the paddle shaft) and operate it by hand. You can easily see where it is giving you problems.There are a couple of places you might have to do a little shimming. The only thing you won't be able to check is the cam reset and if you haven't got the cams too tight that isn't a problem. What is the big problem????

                  Re: PBL

                  I had a 40 laner full of LBS's. they were touchy, i mean we're talkin millimeter adjustments determines when/if the cam flapps flip. and replacing the worn cams and flip spring things isnt cheap. i made due pretty well while i was there. but man, alotta do about nothin, compared to a slowed paddle with a mechanical rudder.

                  IMHO, it would save big $$$ in the long run to just trash the LBS and the maintenance required, and just convert.

                    For all those people that want to trash the LBS. Please send them my way. I would much rather have them than the spring shock setup.
                    Need about 19 of them.

                      Thanks for the help guys, I think that I will just yank it out and break it down. Can't be that dificult. Jim, please forward your mod info to me via message or better yet just place it here in the thread so every one can benifit...please.

                      Hell, if I can figure out how a "B" works I guess I should be able to handle this. [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] LOL

                        All mine got thrown into the scrap pile. Prob. made into a corvet by now. Think I might still have 2 laying in the corner. Plus a couple used for parts laying with them

                          Re: PBL

                          am happy to post it here, just a bit windy, so I will give brief details, and anyone who wants more info, just let me know.


                          Basically it is a mini PBL, with 1 minor and 1 important difference.

                          I use the Kicker Mousetrap (Belt tensioner) assy. but retain the spring hanger on the pulley shaft. (make sure you use the reduction pulley) Instead of using the small spring at the top of the rod, I use the smaller of the 2 Distributor springs.

                          I also Retain the large black paddle drive pulley, but replace the crank shaft and plate with the smaller one from old aluminum kicker crank pulley. (the big crank plate bolts will hit the wide part of the paddle drive shock) You have to drill new holes in the black pulley for the new crank shaft. I also offset 1 hole about 1/2 inch off of center. Then use the adjustable pressure paddle shock adjusted almost as strong as you can get it.

                          For the adjustment on the reduction sheave, you want to make the gap as large as you can without allowing the belt to slip down onto the threads. by increasing the offset of the stud on the pulley, you increase the delay on either side, but your overall travel speed will increase, so you just have to find a happy medium. You shorten and lengthen the shock to equalize delay on either side. (I get almost 2 seconds) You will also have to use 2 36 inch belts to drive it, one from the lift to belt tensioner, one from tensioner to paddle drive. It is unnecessary to change the drive pulley on the lift, but you can if you want to.

                          This has the effect similar to a 10 speed bike. Slowing down the paddle, and the delay allows the 6 lb balls to get back to the door in time.

                          I have a hard time explaining it in writing, I can provide anyone a phone # if they want a better explanation.

                          I am off next 2 day, I will get a full parts list, and a better explanation that I will have available in a week or so for those who are really interested.

                            Re: PBL

                            I have worked with the LBS and the spring loaded rudder link in the PBLs. I belive the best is the rudder link. I have mine set about medium stiffness and with enough travel so that there is enough pressure to kick a pin and a 16lb ball out of the hole. I also feel it is a good idea to use the largest ball lift drive clutch pulleys. This also slows down the lift making life easier on the bearings. Like JimDorsin, I keep the spring on the belt tightener. Without, I never seemed to get enough belt pressure. Makes putting the belts on easier too!

                              Yes, I like the 5 inch lift clutch pulleys too...the thing that my mod has is the bigger back pulley....it almost cuts the speed in half....
