| - | The little roll pin sticking out of the inside of the kicker cover acts as a stop pin. The release should rest on the pin when the clutch lever is fully extended and the adjustment of the release rod is slack. ((Bustert of the XLFORUM http://xlforum.net/vbportal/forums/showthread.php?t=2061986 )) Sometimes they will snap off. This could be due to it being a pretty wimpy size pin, and possibly bad clutch adjustment followed by abuse. ((DirtyHarry68 of the XLFORUM http://xlforum.net/vbportal/forums/showthread.php?t=2061986&page=2 )) \\ Up to '67, the hole was drilled all the way through where you could drive the old pin out from below. However, the sprocket cover changed in '68.

| - | * On further attempts, I succeeded in blocking up the hole with a welding rod, which was supposed to have fused itself to the inside of the pin at low amperage, allowing me to yank it out. Instead it broke off at the top of the pin.

| * A step before trying to spark erode the little sh!t out of there (machine paid for itself, removing broken easy outs, I hear) when I tried a carbide burr. Snapped that too, but it got deep enough to hog the old pin out before that happened, and I managed to pick the broken bits out. | * A step before trying to spark erode the little sh!t out of there (machine paid for itself, removing broken easy outs, I hear) when I tried a carbide burr.

| - | New 1/8” roll pin fitted. If this bigger size makes any difference, you can always relieve the arm a touch. ((DirtyHarry68 of the XLFORUM http://xlforum.net/vbportal/forums/showthread.php?t=2061986&page=2 )) but the larger pin would help with shearing.
