'93 Polaris 350l 4x4. What are the symptoms of a broken piston skirt?
severe knock / rattle under load
excessive smoke as the crack normally occurs at the oil ring groove dropping that ring into the sump
describe the symptoms that you have as if it is a rattle under acceleration that will be detonation and is a air/fuel mixture problem or ignition timing too far advanced the skirt is what maintains the alignment of the piston crown so if it is cracked /broken off you will have no doubt of the noise at idle and at rpms
pistons seldom fail because of the engineering and material used so it would have to be an extreme operation that would cause the failure
other similar noises can be from loose valve seat insert
piston hitting valve head from failed valve spring big end bearing cam lobe worn out

09 850xp won't turn over but power turns on
you nee to locate the battery wire on the starter then with a test light or meter put the probe on the post of the starter and it the start button, you should have 12 v at that point if so replace the starter, if not the check the solenoid

My 2004 Polaris ranger 6x6 won't go into AWD, the switch lights up but no front wheel engagement ?
First off be careful because you will be working under your vehicle.
Check your linkages, fittings, bolts (that none are missing), and splines.
Obtain a new gasket and gear oil then drain and remove the inspection cover (s). Check that the gears, splines, bushings, bearings, etc. are good and intact.
Check oil sump areas for fragments or broken parts.
My guess something inside the transfer case has snapped but you never know could be something that came loose.
