Question about water pump impeller

Flywheel,stator and plate and even the recoil cover can stay on. You have to get the cam at tdc. Mark the head inline with the index pin. Remove the tensioner, thermostat housing(to get to the cam plate) cam plate and rocker arm blocks. Remove the sprocket(without moving the flywheel and let the sprocket and chain drop down. Pull out the old cam,in with the new one and align the sprocket with the cam. Wiggle the chain if you have to but not the flywheel... The rest is on the post you found.

That's the thing on most of the aftermarket cams shown. They don't list whether it's an actual HO cam or not. Only difference between the two cams was the duration. Lobe height was the same on both HO and non HO cams. They are mostly listed like this.
THIS PART REPLACES OEM POLARIS #'s:
CAMSHAFT:
- 3086212 (Non HO cam part#)
- 3084898 " " "
- 3085855 (This is the HO cam part#)
Haven't heard of any complaints from people on these after market cams so far.Either one of these aftermarket cams or $230 or more for just the oem cam,doesn't include the rocker arm.
