Hello all , new to the forums here just want to say thank you for all the helpful tips so far.
I recently purchased a 2006 sportsman 500 ho efi with 5000km. Great condition overall. I was out riding last weekend and noticed the machine was stuck in awd no matter what I did I couldn't get it out.
This week I drained the fluid and disassemble the front differential and didn't see any damage to the cage or rollers. All gears gears bearings and seals are good. The armature plate had some wear rings on the back side .
When I applied 12 volts the armature would stick to the "case side" and with power removed it will not unlock.
I ordered a new John Deere armature installed it and bench test does the same , except when I rotate the prop shaft in reverse direction it will unlock the armature.
Put the differential in and went for a test ride awd engages but to disengage i need to put the machine in reverse for a brief second then back to high and it is back in 2wd.
Anybody have this problem? I like my equipment working as it should but maybe this is just a quirk with the machine?
Any tips would be appreciated. Thanks
