  • PBL upper pulley

    I am wondering what I am over looking here.
    Have a few PBL's where the top pulley does not sit straight. The wheel is turned off at a slight angle.
    I have replaced the roller assembly that the bracket sits over to help reduce play. Have squeezed the bracket tight so it fits snugly onto the roller so no movement from side to side. Adjusted the spring.
    What am I missing here? Is it due to the pin that intersects the PBL shaft holding the yoke securely?

    one possibility is that the ball lifts were converted over to pbl and the brackets where the links connect were not installed properly.

      I have taken a steel pole, stuck it between that bracket and the pulley, and twisted it to make it straight. There might still be a little play but at least its centered up.

      I have yet had anything break but youve been warned.

        rd, a bit of heat on the main tube might be a good idea, if the lift would be out of the machine.

          Loosen the 2,3/8 bolts on your bracket and then you can twist the upper pulley to align, then tighten both bolts

            I like the roller and the aluminum casting to which the channel bolts to fit on the snug side especially if you are running Humpbacks like we are. It will bend very easily by taking it off and tapping one of the lips on the channel with a hammer on the floor or a steel plate. By hitting the bottom lip where the roller rides will move the pulley to the left. Conversely, by hitting the bottom lip where it bolts to the casting will move it to the right. When these things are formed at the factory, they are not always (right on the money) and need to be "tweaked"
            Yeah but, We've always done it that way.

              The head of the pbl twists if you have altered the spring length, so just take it in your hands and twist the head in the direction you want to go. that is the plate on the sides job, to hold it square. When twisted straight, it will stay in line.
