XC600 Crank Bearings

Yesterday while flying across a field the motor locked up solid on my 98 XC600. After a little while it loosened up and I was able to start it to get it on the trailer. Any thoughts? Maybe a crank bearing or a sieze? Anyone else have any problems on this sled? Thanks Mark

Sounds like a cold piston seizure, had you been running a while, Or was it right off the trailer? If it was crank bearings, it most likely wouldn't have started back up.

Re: XC600 Crank Bearings

I had been running for several hours. Earlier in the day when I was running wide open for a while it started to bog but when I stopped it idled fine and ran fine after that. I hope it isn't a seize, I hear the jugs on these are expensive to repair. Thanks Mark

Re: XC600 Crank Bearings

Is there a chance you sucked in some snow? On those piston port motors, sometimes if you are in deep powder, you can suck some snow in and clean off the lube on the pto piston causing some problems. The easiest thing to do is take off the carbs and look in your intakes and see if any of your pistons are all scarred up. Then take a bore light and one by one drop the pistons to the bottom of the stroke and look in through your spark plug holes to see if you see any scarring on your cylinder walls.
