i have a complete reman polaris 800 crankshaft for 2000 to 2005 bb 800 has all new mains with the 800 dragon pto bearing on it, this is one of the best things you can do to help prevent pto breakage some case mod's may have to be done if yours are not done already and pto crank seal modifacation has to be done. but this works well i have a few on the snow and they are working great. $500 exchange also case modifacation available if needed. you can call if you have any questions 435-979-1189
