@rplst8 posted:I’m beginning to wonder if it’s the not movement itself that is the problem, but rather the spacer bushing riding up against the shaft bushing and grinding it down. For models with a lot of travel, they get more movement. For models without much travel, they eventually still will probably get additional play, but maybe never enough for gear disengagement. For models that have a spacer bushing larger in diameter than the shaft bushing, it will probably never be a problem.
This is what my findings were from the get go on page 1, then re-emphasized on page 4……more than likely, the ill fated 2011 batch of K4s’s suffered from some sort of portly manufactured bushing material that simply accelerated the disintegration, but I can’t see any of the gear boxes WITH THIS particular design lasting without some side shifting. That’s the idea behind the “fix” ….we’re taking away the variable, and now the two pieces can’t meet up to kill one another…..😉
