  • New to the gearboxes..

    Hi guys!

    Had a problem crop up here tonight. Lane 7 started piling up. After a few pileups in a row, i looked into it. The distributor runs fine. EXCEPT when there's more than one pin on the belt at any given time. I thought the belt was slipping.. not the case. When I placed my hand on the dist belt, the whole distributor stopped moving. The drive shaft from the gearbox stopped too. This gear box has had a slight leak for a while, but not a large one. The pinwheel pulley output shaft keeps running when my hand is on the dizzy belt. It doesnt affect that. I have no clue what's inside a gearbox other than an input and output shafts and gears

    I believe it's a Westinghouse gearbox. Not 100% sure though.

    Any help would greatly be appreciated!!! If you could, please post pictures with your replies! It would help us out a ton!

    I'm not familiar with a westy BE internals but from what I understand its a:

    National if the motor bolts on with 3 bolts
    Westy if the motor is held on with the 4 motor rods that run all the way down and the flange has no see through openings
    GE if the motor is held on with the 4 motor rods and there ARE 4 openings at the flange.
    When you know what to do, everything is easy.

      if it is a Westinghouse. this could be very simple. Where the dist drive shaft goes into the "u-shaped" slot there is a key in that and it may have broke. If you take the drive shaft out there will be a set screw in the bracket, just loosen that up and the bracket will come off. You can then check the key and also turn on the B.E. and see if the shaft is moving. Whatever you do though keep your hands out of the way while it is running, it will crush them.
      Sometimes we have to do stuff to get by....Just go back and do it right when the "by" has passed!!

        If you're lucky, it may have sheared the key on the dist. weldment. ( where the drive shaft balls slide in) but it probably spun the teeth off the end of the shaft that runs the pit belt (a112 belt) drain the oil, take the 3 covers off, slide everything out and you will find your problem. Or send in for exchange.

          Cody,

          It sounds like the very small key that locks the gear to the shaft sheared. If the gearbox is a real old West., some of the gears were pressed on the shaft and over the years will come loose on the shaft. If it's the key, then you will need a new shaft, key, and gasket to fix it. Take the motor off the machine and drain the gearbox. Take the 4 screws that hold the drive shaft cover in place out. Be very careful when working with them because they strip very easily. I think they are made of aluminum. Slide the cover off the shaft and remove that old gasket. Take hold of the shaft and wiggle it till it comes free. Slide the asy. out. Take the parts off the old shaft and transfer them to the new one using the new key. After putting it all back together, reinstall back into the gearbox. Before putting the cover on I'd replace the seal too. Clear off the old gasket material and using brown Permatex (aircraft quality) coat the box and put the gasket on. Next clean the cover and put some Permatx on it then slide the cover onto the shaft and install the screws. Let the thing sit for 24 hrs., refill the box, and it should be ready to go. I have at least 2 of these shafts made up incase one gets bent or sheared. Will try tomorrow and get a picture of the shaft and key. If you run into problems you know how to find me.

            On the end of the dist. shaft the small bearing likes the fail and that causes the two gears to strip out.

              We changed the whole gearbox off with another that is working now. The key on the shaft that holds the dist drive shaft is still in good shape. I'm certain that it's bad inside.
              Is it pretty self explanitory inside? We havent taken it apart yet.

                The back end gearboxes aren't too hard to pull apart and rebuild provided you don't have to replace the worm shaft! It's a bit long to type out the procedure here, but I can give it a shot if you like. It may be easier to follow the manual though, which you can download here http://customerportal.qubicaamf.com/...ls.aspx?page=4 or I can email it to you if you send me a PM.

                Best of luck! Andrew

                  HERE IS ONE PICTURE THAT I'D LIKE TO BE PUT UP.


                  CODY:

                  Here is what the dist output shaft looks like. Where the pointer is,
                  that's where the key goes that holds the big gear.

                    Thanks Doc! That's the key that you're referring to. Wasnt sure on that one. We havent yet pulled it apart to look but I'll definitely make note of it and let all of you know what we find!!!

                              As to the photo shown , it may be that the spigot shaft has broken that goes into the bearing , had this on a few occasions now and problem was how you described it
