  • Locked up gear box

    Hey guys. Yesterday, I believe my gear box locked up, and I'm really not sure what to do. It is at 180 standing pin. So the pins are in the scissors. I can't manually dis or re engage the clutch. By pushing down the actuator and everything, nothing will click into place. I can spin the worm shaft rod, but the pulley that the belt is on won't budge. Anyone have any advice for me? It would be greatly appreciated. Thanks!

    Try putting a wrench on the nut closest to the clutch cone. Make sure you are turning to back up the machine (clockwise).
    You don't have to be crazy to do this job...But it helps!

      Well if the pulley with the belt won't turn, then it sounds like the pulley bearing is frozen. If you can rotate the worm shaft, you should be able to get the gearbox to move. Seeing that it is on STANDING pins, you could pull the clutch apart. If it was making noise before this happened, I would guess a bearing. Good luck.

        Phil he said that it is at 180 and clutch disassembly would be dangerous.

          If you can turn the worm shaft, remove the motor to elevator belt and see if the motor will turn the gearbox or turn the worm shaft nuts as cuda96 suggested. The bind may not be in the gearbox.

            He said standing pins...if the pins are in the air, then do not pull the clutch unless they are on the floor.

                  Curious... Why are you posting this again when on the 12th, you had already posted about this same issue (entitled "worm shaft nuts") and had some good replys?

                    I believe this reply was somewhere in your other post, but I will post it here because I experienced it. I had the same issue on a machine. It would cycle freeze and squeel. I could back it up manually like clearing a jam, and it would run to that point and then freeze again. I bring this up because I believe (it was quite a while ago) it was around 180 standing pins cycle. Just needed to top off gear box oil and it was all set.

                      You state that you can spin the worm shaft rod...but the pulley won't budge. What happens when you spin the worm shaft rod?

                      You can take the clutch apart at any point in the cycle unless you have 27:1 worm shafts and worm wheels. You can NOT remove the worm shaft at certain locations in the cycle...but taking the clutch apart is not removing the worm shaft. Take the clutch apart and see if you can get the deck back down. Either direction will do...once you reach 90 or 270, you can remove the worm shaft if need be.
