  • Pinwheel belt

    Hi all,been experimenting with the 5" pulley to reduce the speed of the pinwheel.
    Got the pulley mounted to a Westinghouse 50hz.
    Now, I read somewhere that a 188" belt would be needed to fit this reduced sized pulley,so I duly ordered one but found it impossible to fit due to being too tight....so I ordered the next size bigger and this too was too tight!The next size up from this was the original belt I had fitted!
    The pinwheel would rotate but any resistance from there being to many pins in the pinwheel at once would cause the pinwheel to stall.
    I tried to add pressure to the belt tensioner but this just made it worse!
    I came to the conclusion that the belt was just that little to big and not having a belt to fit that exact dimension am back to square one!
    Anyone had this same problem?

    The 188" belt is needed for 4" pulleys.

    The 5" pulleys can utilize the original belt.

      Re: Pinwheel belt

      Have had wonderful success with BK50 pulleys combined with B-188 belts.Then I shimmed up my B.E.gearboxes with some 3/16" hard plastic between drip tray & gearbox.This "raising up" of the g.box has been paying dividends by:
      A)Dist. drive shaft is closer to level causing less continuing wear to u-joint.
      B)A-112 belt is now tighter, releiving the occasional wear on the small belts tentioner.One can even omit the A-112 tensioner if one wanted,as well.(I don't,however)
      C)The little gap that you now have between bottom of gearbox & drip tray will now neatly accept a minipad if you have a leaky g.box you're not quite ready to reseal/level out just yet.
      D)And as previously stated;gives you the good fit/tention on that pinwheel belt.

        I like that shim idea. When I have 5" pulleys with original belt I use a heavier spring. works well. I think it is a kicker spring. Post if you need a part #

          Re: Pinwheel belt

          Another thought though. If you shim the motor up and have 5" pulleys on the ball lift the a112 belt may be too short

            Use the adjustable green 82-30 belt!
            So it goes.

                Nice point 70.
                My appologies for forgetting to add that I have also changed out the original 3 1/4" carpet drive pulleys in favor of AK 28's (2.8" I'm gussin').This smaller pulley slows down carpets,lift belt,rudder etc.

                Also,neglected to mention that to help in the leveling process of back end gearbox,we put one small washer in each of the bottom holes of the b.e. gearbox brackets.This brings the stator end "up".That translates to reduced leakage out of the notorious dist.seal and the shaft above it.

                Good stuff!

                  We have the "holey" belts on a bunch of machines. We buy them locally, but they're about the same as the 82/30 ones.

                  The biggest thing I like about them is that we can thread them around the wheel without having to move other parts (like the distributor post beam). Makes 'em a lot easier to put on.

                  We made a tool to tension them up pretty good. We took a pair of Vise-Grip C-Clamp pliers and welded a set of nails on to the jaws. Stick the nails thru the clamps, pinch the pliers a bit to pull tension on the belt, cut it as needed, and attach the metal splicer easily. Time, knuckle, and aggravation saver... and you don't need 4 hands to pull the belt together and attach the clamp.

                    Re: Pinwheel belt

                    When I shorten a belt on a 30, I take the belt off the pinwheel, unscrew the clamp bars, cut the belt, put back the bars, then roll it on the wheel. Simple, one man job.

                      Gman. Where are you getiing them locally? And how much? My suppliers want big $ for the stock 30 belt
                      NOOLIO. What does slowing the carpet do? Changing the carpet pulley would affect the carpet only. (other than giving you room to shim the motor).
                      I'll look into the washer idea. D*mn 70 BE's all leak. I had 50 yr old 30 BE's that were dry (on the OUTSIDE)

                      Has anyone tried a smaller pulley on the motor? This would slow ALL of the ball return. Might be a problem if you have kickers?
                      I have PBL's. What would you kicker guys think?

                        oops I was thinking of the pulley on the rear roller. I kinda missed the 3 1/4 " thing. You answered one of my ?'s
                        Thanks

                            I've 5" pulleys on westy's &amp; Nationals and I'm just trying something at the moment &amp; seems to be working ok. I've replaced the belt tensioner pulley (070-002-094) with ratchet tensioner pulley (000-021-408). It looks a bit odd but fits ok and is a straight swap. With greater surface contact the tension is higher and you can use the original belts. What do you think?

                              The place we got them from was Holmes Metallic, now called Bearings &amp; Drives Unlimited in Wilkes-Barre. They have a couple locations:

                              If I remember right, they sell it off a bulk roll, and you just buy the clip (2 screws &amp; 2 plates) to put it together. I seem to remember the clips being around $5-8, but can't place what the cost of the belt was. The belt has to be pretty well tensioned, because to use it you have to remove the belt tensioner... the clip can't be bent backwards (hence the reason we came up with the "tensioner" tool.
