  • A question for King and some old heads

    I always wanted to ask about this and never got around to it.

    Why, on the sweep rocker arm assembly, is there that drive rod connecting block on the table motor side of the rocker arm, for the long sweep drive rod. There is no block on the sweep motor side.

    I always had to run the table side long tie rod longer than the sweep side long tie rod.
    If both long drive rods are set to same length, the sweep goes farther into the pit on the sweep motor side.

    I never understood why that block was there!
    Maybe one of you know why!

    Its very simple. That block is there to allow the rocker arm to go under the table gearbox. If you look at it closely with the sweep at zero and imagine if it was the same as the ten side you would see how it could run into the gearbox which is why the sweep drive rod can be no shorter than 10-1/8". The pivoting points on both sides of the rocker arm are exactly lined up, you can see this with one out of the machine, and the block is added there because the arm on that side is slightly rearward as compared to the ten side and the block puts the mounting hole for the rod in the same spot as the other side.

    Its funny you ask because I used to wonder the same thing.
