  • D-Shaft assy

    Is it possible to replace a d-shaft assy while it's still in the detector?I have a machine that once in a while it will set pins while being held up on the lowering hook,problem started after a clutch reset lever cracked at the weld,i replaced it and adjusted the dashpot but every now and then it want's to set pins the wrong way.,all else seems to be fine,i am thinking d-shaft has a problem,if at 270 i move the d-shaft inward i can get the lowering hook to slip off and it seems to easy to get it to slip off.I see nothing binding in the detector,no excess oil to make something slip off and blocking surfaces are all good.Now it's starting to bug i thinking in the right way...D-Shaft assy?,worn out spring or bent shaft?
    Adjustments are on yet it wants to slip off.It's bugging me alot more now!

    Run machine to 270 setting pins, unplug. Remove x washer pin from butterfly ( flag actuator ), roll pin from strike cam follower then slide shaft to seven pin side untill the 12-150183 hook selector latch can be removed. Either replace with a new one or resurface old one on a belt sander, needs a sharp , distincitive point on it. Very hard to accomplish on any thing but a belt sander.

      Did you mean part #12-100183,lowering hook selector,it's the only number i locate for that.
      (pg.14,#gb196 in the service parts book).I don't have a spare(yet)but i did try to smmoth it off some and i was getting a better hold after that instead of slipping off.
      In amongst stuff lying aroung in back i did find a partial detector and will have to finish it so i have a spare,it will be my first detector to rebuild.,then i can swap one out when need be.
      Thank you for the advice!

        Sounds like this place when I first got here, the detector was in a 5 gallon bucket of oil and in more pieces than I could ever imagine, I thought it was for spare parts until I removed all the pieces and cleaned them up. Having never rebuilt one before it was to say the least a fun job. They are really not that bad if you don't get in a hurry and just accomplish one section at a time. We remove the D shaft every time we change the hook selector bearing so changing it out should be the same process but you would remove it entirely instead of us only sliding it back half way.

        Have fun with it!
