Replacing a Broken Pallet Timing Bolt on a V3-12

Note: The following steps are to be followed when the only thing wrong with the pallet timing is the fact that the timing bolt has broken. Make sure that the pallet chain, located under the machine and the sprocket drive chain on the right-hand-side of the machine has not loosened up.

 

  1. Run the machine around until the PALLET DELIVERY ARMS ARE JUST STARTING UP.

  2. Note: Looking at the block placing or pallet moving cam ( farthest cam out on the left-hand side of the machine), be sure the roller is on the KSL (key seat line).

    Note: If the arms move too far you will not be able to place the pallet into the pallet-cradle.

  3. Lock and Tag the machine out.

  4. Take a pipe wrench and proceed to the back of the machine and place it on the pallet feeder back shaft.

  5. Place the pipe wrench on the bottom-side of the pallet feeder shaft and pull up on the pipe wrench until the pallet closest to the pallet cradles sits about ½ to ¾ of an inch back from the front end of the pallet cradle.

  6. Note: Make sure the pallet does not come into interference with the pallet positioning springs.

  7. Proceed to the right-hand side of the machine and replace the pallet timing bolt part no. 088041, use adapter (2) part no. 059425, lock-washer part no. 087881, and nut part no. 087806.

  8. Remove the lock from the electrical panel and run the machine a couple of cycles in order to check the pallet timing.

** Publication does not constitute approval for constant usage of this method. If repeated bolt breakage occurs, the cause needs to be determined and corrected to prevent further damage.
