John, I have seen a crank seize in one instance on a friends ski, it would get hot and lock up tight, we removed the jugs and inspected, all checked out fine. Told him then something was phunny in bottom end, noticed a little slop in the PTO rod to crank bearing but he really wanted to try to run the ski again when I told him the prices for a crank kit. Any way he tried the ski again that weekend with the same outcome. So finally convinced him to tear down the bottom end, what we found was somehow a roller or two had gotten broken and fell out. And had assumed a sorta/kinda square shape [img]smile.gif[/img] Any way while cool they would allow the crank to turn but upon heating would sieze the lower unit. I guess if you look long enough you will see all kinds of strange things happen!
