I have been having with my 2008 Polaris sportsman 500 ho. My issue is that my atv won't come out of 4x4. It is stuck in 4x4. This happend after I serviced the atv.y buddies told me to see if it's atv actuator switch or pump, but I can't find the part anywhere. Is there anything that you would recommend for me to look at or troubleshoot so I can maybe get an idea what the problem might be?

 

Problems most of them have are either a magnetized armature plate,cracked roller cage that keeps it engaged,and rare occasions the coil itself. If you used the correct fluid(Demand drive Plus) and it still does it about the only thing you can do is to tear it down and check it out.A lot of people are going to aluminum roller cages to eliminate cage problems.Dirt Cheap Yamaha, Polaris, Suzuki & Kawasaki OEM Parts & Accessories – Cycle Parts Warehouse

The exploding Plastic Roller cage was a issue. Why was it in the shop? Sure can't blow up a cage while its in a shop ,unless a employee went for a secret test ride.
