I recently replaced a set of K&B short arm jacks, and many of them came out on an angle after pushing the new center pin through - the tops of many jacks were not centered in the rep. lever slot, rubbing against the side of the slot. Could it be that the manufacturer of these jacks drilled the tiny center pin hole inaccurately in many of the jacks? Would a worn out center pin tool cause this problem? Even if there were some play in my center pin cylinder, wouldn't the center pin find it's way through the hole and not deviate at all? -------------- next part -------------- An HTML attachment was scrubbed...
