My trusty steed finally gave up a few weekends ago, and curious of ones opinion on how things came to this. History on this unit is that it has been the best Polaris I have owned.
Started mountaing riding in 2009, and have only owned Polaris'.
Did the original topend at 200 hrs 3100 miles, as leakdown dropped to 6-7% on PTO side, MAG was 2-3% still. Was suprised it was solid numbers until this point. Fresh top end lasted 20 hrs, as I broke a wristpin clip that went through the piston/cylinder on the MAG side. Replaced cylinders and new piston kit installed last fall. This season she made 6 days of riding, until she seized up at the end of March. Was in a bad spot tree riding, so I worked the clutch free with my shovel handle while putting oil into the cylinders for approx and hour. Got it running and made it back out 2-3 miles to a trail that was able to tow it home from, seized solid at this spot. 4400 miles, all mountain. Have the engine torn down and PTO bearing must have been going as it got hot !, The 2 oil lines going to the PTO side were melted off their spigots. PTO bearing inner cage melted away, and crank lobe worked itself off it's pin and into the case and away from con rod. Now, it's looking like she needs a new long block. Anyone ever seen a crank porkchop come off its pin like this ?
