  • 4:1 Shaft Replacement

    Greetings all. I have an A-2 that has a lot of slack in the 4:1 shaft. I can lift the 4:1 arm up and down over an inch and the rest of the gear linked shafts also move (2:1 and 1:1) Seems to me to be a bad key way in the worm gear/ 4:1 shaft.
    I have looked at the Brunswick book for removal of 4:1 and I wonder if there are any short cuts or easier ways of doing the removal. I am working in the local center as a consultant and temporary mechanic. I have done a lot of repairs on A-2's but never a 4:1.
    Customer wants to run the mach but I advise against it. It seems the detector is off by a tooth which just makes things more complicated.
    Any input is appreciated.

    Ross has all the shaft removals in the technical reference forum. I do mine as Ross.
    My father told me to never get old...I should have listened!

          Hey, guys. I changed a 4:1 today and after we fired up the pinsetter, it began emitting a high-pitched squeal from either the worm shaft or somewhere else. It didn't start until...
