  • Pulley nut backed off !!!!!!!

    So my belt broke recently... I have a custom back fender and thought that it may have got into it . But after getting it home the pulley nut backed off . It looks to have buggered up the spline . Any one know what kind if job this is going to be ? Is the transmission separate? A new shaft and pulley does not look to be expensive...I've read you can weld it ? Is that true? Any input would be greatly appreciated. I'll come back and post pics once I get it in there and see what the spline looks like . 2007 R* 1700

    It’s not the transmission, it’s the transfer case that just has two sprockets and a chain on the right side. Before you replace the final drive shaft, at least see if you can get the final drive pulley on the left side tight. Sometimes it’s just the pulley that is damaged and needs to be replaced. If not, several folks here have replaced the shaft. You do it from the right side, not so hard, just time consuming. Don’t weld it, cuz you could damage the seal and never be able to remove it in the future.

      if you welded it and needed to remove it in the future you would just have to grind the weld off to remove. It wouldn't be stuck forever. If mine ever gets damaged it will get a new seal installed and then welded to hold it. I'll worry about removing it in the future if it ever needs removed. But that is my bike not yours. If I was to repair on someone else's bike I would replace the parts unless requested to repair by welding. I just wouldn't be concerned about welding it. The worse that could happen if it didn't work is that you would have to replace the parts and that is where you are now.

        Those are my thoughts exactly. If it is damaged enough to have to replace it I feel welding it would be the less time consuming. And if it ever fails I really dont see it being to hard to get off. I'll see when I get the nut off tonight. In posting a couple pics of the spline let me know what you fellas think .

        You won't know until you actually remove the entire pulley. It could be that just the splines on the end of the shaft are damaged and not along the entire shaft.

          check Pinwall cycles or Sun coast cycle sports for used parts.
          suncoast has the transfer case with shaft:

            Good looking out man! I bought that one . Got it for 110$. Saved me a bit of money for sure . The shaft alone was 295$ from a dealer . I'm gonna try to tack the old one but I'll have this one and maybe swap them out over winter . Thanks again !

          i found some years back that my nut had also come loose, there was some 'lash' between the teeth on the pulley and splines. i used permanent thread locker on every spline and re torqued up the nut. it has been fine ever since. i have warned my friends about the nut coming loose. when i did this work the squealing also stopped.

            I, too, had one come loose, resulting in some lash between the teeth on the pulley and splines. I was told on the old Clinic forum it might work to Loc-Tite red the whole thing up. I did, and it has held ever since... Can't remember how many years back it's been.

              Well the spline looks to be good and just as mentioned only messed up on the front edge . Buuuuutttt the threads on the the shaft are destroyed...I'm guessing the only option now is to replace right ?

                  Yeah looks like the threads are pretty much toast.....soggy, old, wet toast. You can replace the shaft thru the right side I think.

                Maybe just a new nut with original deeper threads?

                  It looks bad.... I think I'd just go replace the shaft thru the right side.

                    I would still replace the seal and tack weld the nut to keep it from ever moving loose.

                      Dave the pic I seen where the nut needs to sit there are no threads to file, wore down to the shaft.

                      Mort the pics above look like they have about 6 or so threads next to the splines. that should be enough to start a nut to weld.Grinding the buggered threads on the end of shaft off to make that part of the shaft a smaller diameter should allow the nut to pass and allow it to get to the few threads remaining by the splines. He does have a new case coming so I guess changing it isn't that big of a deal either. Just thought a quick fix would work to finish out the season and swap boxes if needed in the winter down time.

                      I'm definitely looking for a quick fix then I would rather tear it down this winter . Time is something I dont have a lot of

                    i'm with Dave, nothing to loose this way.. used to do that on my old sloper panther. such a shame nut a timely reminder for us all.. and Questcap; that's where i got the idea from the old RS clinic

                      Hey Jed,

                      Sorry to heard about the pulley nut, bummer. For reference, how many miles are on your bike?

                      Thanks for the update Jed. I bought mine used so who knows if it was ever checked before, I’ve got 28k on the clock so I’d better check!

                        I am a machinist and have drilled and tapped nuts between the id and near the flats in 3 places with a small set screw. After you tighten the nut, you simply tighten up the three set screws. depending on how thick the pulley is behind the nut, you could lightly drill into the pulley about .125 deep and use a pointed set screw, therefore locking the hole system down, never to back off again.
