Apex 10 Stacked Tube Primer Assembly

[HOGRIDER]

Ran into an issue recently after installing a new #101-1181-01 Primer Housing Assembly that was replaced under warranty; and wanted to share my experience in case anyone else was having related issues.

 

Seems there was a run of Primer Shuttle Disks that had substandard machining on the U-shaped cutout that receives the primer from the Tube Assembly.  Started pulling the handle to begin a stroke, and for some reason the disk was sticking under the tube.  Of course when this happened, the toolhead alignment pin would hit the solid part of the disk and stop abruptly!  Discovered that raising the handle just a bit would all of a sudden release the disk and allow the entire stroke to be completed.  Was constantly happening; but just that bit of raising and lowering the handle would free the disk and allow the load cycle to be completed.  Short-stroking DID NOT come into play as the handle was only being pulled/returned enough to start the rotation of the primer disk.

 

My research found a couple of other users had recently incurred the identical situation; and one even had an excellent video showing the issue.

 

If anyone is experiencing a "sticking/hesitation" of the primer disk as it rotates out from under the primer stack tube, remove your tube and take a close look at the receiving notch in your disk; specifically the right half of the cutout:
