i hav a 2001 polaris scrambler 500 an i was wondering does anyone know the procedure to replace the crankshaft on it. my crank shaft snapped on the magneto side. and i was hoping to replace thaat third can any one help me?

 

Thats a pretty big job, have to take engine out of bike, take the top end apart, spilit the bottom end cases and I would replace the entire crank , bearings and rodwith new bearing also

 

Replace it with a four stroke tech crank and get the big bore kit while you are at it. 628 cc's!
