I  can't give  you  any specific instructions on  how to  access it, but  can  give you  a tip  on breaking  loose  and  removing the  nut holding in on the  shaft. Most try  to  do  it   with  just  putting the  quad in gear  to try to  keep the  shaft from  turning ,  but the  nut is usually    so  tight  it  turns  anyway ..   Put  the  chain  on the  sprocket  and then  clamp the  chain  so   it holds the  sprocket and keeps it from  moving while  you  undo the   nut .. There  are  videos   on  Youtube  showing  others  changing the  drive  chain  so  you  can see how it  is done  and  adjusted.  I didn't see  one  on   changing the  Polaris  sprocket though .  Search   Youtube for  changing the front  drive  sprocket  on your  machine . You may not get  a full  video of  your  machine   but  you  will  get videos of  others  being  done . . I  didn't see any  mention  using the  chain  to  keep the  shaft from  turning when  you  go  to  remove the  nut but  it  is  a  trick I've  used  many times   removing  sprockets   on machines a  lot  bigger  than   a  quad..   LOL... Wrap  that  chain   around the  sprocket  and  clamp  it  so  the  chain  can't  move  and  the nut  will  come  off without  the  shaft  moving.
