RM Stator Improved Capped Magneto FF97 Flywheel for Polaris Sportsman Scrambler Magnum 500 1997-2004 | 3086983 / 3087166 / 3085558

Introducing our newest Heavy Duty Flywheel Rotor For Polaris ATVs.

Anyone who rides or repairs Polaris ATVs is probably familiar with the flywheel problems common to these models. Most of these machines will have at least one flywheel failure in their lifetime so far. Low quality epoxy was used on OEM flywheels to secure the magnets to the rotor body. Over time and many heat cycles, the epoxy fails allowing the magnets to come loose and contact the stator, potentially causing catastrophic damage.

For years, service shops & dealerships have offered low cost repairs for Polaris flywheels to save the 400$+ OEM replacement. This sounds like a great idea at first, but there are some serious issues!

The common repair is using JB Weld© Marine Blue Epoxy to reattach the loose original magnets, or to install new ones. Epoxy fixes do repair flywheels in short term, if they are done correctly. However, this kind of repair can easily cause immediate problems, and impact long term reliability of your ATV.
