    Hi Brandon, Here's the way I do it. Clear deck and pit of pins. Pull pit board. Undo pit frame and pull it towards the front. Remove ball belt from tension idler. Loosen top rollers on both sides and pull out of the way. Remove the allen head screw that holds the roller on the shaft. If it wont slide of because of wear on the shaft, you will have to take the whole unit of. Right behind the shaft there is a large allen head screw that needs to be loosened. Take a 1/4 inch allen wrench (I think) insert wrench and give a good wack with a soft hammer. Remember this is a left hand tread, so turn it clockwise. You might have to cut part of the allen wrench off to get it inserted. Hope this helps. PJ

      JUST WANTED TO ADD
      THERE IS NO ALLEN BOLT IN THE BACK. THIS IS ONE OF THE OLD SOLID AND IN PLACE ONES.

      ANY OTHER SUGGESTIONS?

          to remove the roller this is what i do:

          remove nuts on the rear pitframe mounts( i use the old style) if you use the new style remove the nut, bolt and spacer). remove tension from ball wheel belt. loosen upper ball wheel guide roller arms and flip pull them up. i use a 3/8" threaded rod that i bent to hook around the bottem of the upper pitframe and the cross conveyor support. hook the rod under the upper pit frame lift it and hook the rod to the cross conveyor support. then lift ball wheel and put an old jackshaft under (at the top) the ball wheel the ends of the jackshaft should sit on the top of the elevator frame and the motor mount shaft. if you have kickers on the ball wheel put the jackshaft on the kicker. this will keep you from damaging the ball wheel. then you should have easy access to both rollers. hope this helps.

            A2,
            I assume you are having trouble getting the roller off the shaft...not figuring how to get to it. Try this...remove the obvious items as everybody else has stated. Reinstall the Allen cap screw without the countersunk washer that holds the roller to the shaft. Remove the cap screws holding the front flange onto the roller. Obtain a harmonic balancer puller from the local automotive parts store. Use two 1/4-20 X 3 inch bolts through the balancer and into two opposite holes that held the flange on. Now remove the roller like it was a harmonic balancer on a car. Sometimes the rear bearing will remain on the shaft after the roller and front bearing have been removed. If this happens...you will need a bearing separator. Some automotive shops will have them...some don't. Here is a link to a picture of what I'm talking about.

            This one is quite large...but you will get the idea. Use this with the balancer puller and remove the stubborn bearing from the shaft. To replace it, I would use the Quality part number 12-4238. I hope this helps you.

            Just my two cents worth...

              A2:
              All good suggestions.
              On the welded ones, I soak them with WD-40 and drive two curved short tire irons down between them and the frame,curved side to the trunion, as JBEES says, sometime the rear bearing stays on, but easly driven off with the tire irons, reversed. As with any hammer assisted tool, safty glasses de rigure.
              Carry four different types of tire irons, and never changed a tire yet.
