What is the best technique for cleaning the clutches? Straight from the center out, or in a circular motion? Pre spray with WD40, then rinse with Brake clean and blow off?

 

Just blow em out first in an open area to get the majority of the belt dust/dirt so you don't breathe this crap in. Best to remove the rear clutch so you blow out the back area around the helix.This area usually has a lot of trapped dust.Then you can spray brake/electronic cleaner to get the residue if you wish.Even better with the rear clutch off to go ahead and break it down and replace the ramp buttons while you're at it.

 

Thanks OPT! Does it matter where I source thebuttons from? Going to bite the bullet and get an SLP Clutch press.

 

You don't need the clutch press on a non ebs clutch. Just tap the helix down with a dead blow hammer a little enough to get the circlip off. Same way when you install the buttons,prewind the clutch,just tap it down then use c clamps to hold the clutch sheaths or helping hands,then install the circlip back on. If you can find after market buttons,probably wouldn't matter,but I've never looked.http://www.ebay.com/itm/3-OEM-2011-2012-2013-Polaris-Sportsman-400-500-4x4-HO-Secondary-Clutch-Buttons-/400742053733?hash=item5d4e167765&vxp=mtr
