    Rear Wheel Help

    Hello All

    I have my bike on the bike lift in neutral. I can rotate the rear wheel only a few inches but it won't spin freely. Isn't it supposed to spin freely? I am finishing a complete frame off rebuild so I am not quite sure what to expect. However, if the bike is in neutral shouldn't the rear wheel spin?

    Dragging rear brakes?

    My first guess would be a rear brake issue,
    # 1 try loosening the bleeder valve or #2 remove the caliper completely
    From there I would continue to move forward as needed ...hub,Differential,shaft, middle drive etc..
    Keep after it

      When you spin that rear wheel in neutral you are spinning, 1 the wheel, 2 the final drive, 3 the driveshaft and U-joint, 4 the middle drive, 5 a portion of the gears in the transmission.

      And most of those components are bathed and/or submerged in thick oil.

      The shaft drive system isn't the most free wheeling type of drive, but definitely the smoothest.

      Chain drive is the most free wheeling with the least resistance but certainly NOT the smoothest or maintenance free.

      If it seems to tight check the rear brake caliper for binding.

        When it comes to the point that it won't go past, is there a metal to metal feel, or just a tightening to the point of not turning?
        If there is a thunk and each end of rotation, it is mechanical drive, if it is tightening, it is probably brakes.
        Since you are stripping the bike anyway, take the drive train apart, and inspect all the components for wear, and any problems will be apparent.

          I know it's not the brake because I don't have that installed. Also, it moves a few inches then it stops. I haven't tried to force anything for fear that the bike might slip on the lift. When I first assembled the bike after the rebuild it wouldn't move at all. So I took the wheel off, dismantled the final drive, pulled the shaft and inspected all. I then reassembled the final drive and put it all back together. Now I at least get some movement which is good, but I am not sure it is enough. Shouldn't I be able to spin it by hand? I have never ridden the bike because it was in such bad shape when I got it so I don't know what is normal.

            One way to check if it's in the final drive or drive shaft is to take out the 4 bolts that fasten the u joint to the middle drive. If it turns then the issue is in the middle drive or the transmission.

              Heh Greg,
              The old "two gears at once " problem?
              2 inches sounds about right for drive train slop.

                You mean if the shaft and the final drive turn after I disconnect it from the middle drive?

                  Yeah but if you read the first post he says it's in neutral CZ

                    If it's sat for any length of time, the clutches can stick together. Even in neutral, this wouldn't let the wheel move any more than the lash in all those components Greg mentioned, since the discs can't slide against each other. Lots of people have had to break those loose.

                      In neutral the clutch is taken out of the equation Tod.

                        Broken shift fork, leaving a gear engaged?

                        Since he has never ridden the bike, and we don't know what "rebuild" entails, TRBIG may have the answer.

                          When I rebuilt (2nd gear fix) the shift forks and gears were all in good shape. Everything rotated as it should before I buttoned everything up and installed the engine. I am going to check the middle gear drive this week. I am interested in hearing more about the clutch plates sticking. Is there a way to check that, or repare if necessary? Thanks
