If the bearing is full of grease you don't need to worry about water and mud getting in with normal driving. No grease as it comes from the factory will fill up with mud and water in no time, guaranteeing a bearing replacement coming soon. The 2020 570 sportsman takes a 35mm on the front and a 40 mm axle on the back. Use red tacky grease and once a year is all that is needed.
Greasing more often is better than not. Water and dust can immaturely where your bearing out sooner. Heat will break down the grease faster and allow water and dirt to stay between metal surfaces causing damage.
Grease often with a water resistant or water proof grease. Grease should push out of bushings. Wipe off excess. I have seen rust powder puff out of neglected bushings
I like my 2002 500 it has wet bath hubs no water issues ever ….. don’t forget the steering zerk under the headlight pod assembly ….I’d use Polaris purple grease or Amsoil grease
My manual doesn't even mention it! I thought my steering was harder than usual! On my 2007 I found an extra 5 spots with zerks. I bet there is more....plastics are coming off tonight after a wash. They change things all the time and its a hassle to figure out.
@@SeanWMODonnell If like my 2002 it will have about 16 zerk fittings … rear hubs, steering, drive shafts check it over really good … hoist it up if you have a safe way to do so
you make some great videos man. i have a 2016 850sp but all the same idea. I have been dealing with clunking into reverse or high, almost when the clutch releases, sounds like either slop in the driveshaft or coming from rear diff. Im lost, the machine only has 50 hours and 400 miles. Any ideas?
I also can’t find any grease fittings but the one on the prop shaft, any idea where they would be on a 2021 sportsman 570? Thank you for the video, it was very helpful
I have a used 850 and i noticed one of the rear wheel bearings was installed with the removable race to the outside. I greased and reinstalled do you think its a big deal? Or should i change it?
Should make no difference. I have seen them both ways from the factory. Just keep it well greased. Positive side is they are very cheap to buy when they do go bad. Good luck!
I ordered a Polaris 850 Premium Trail model, should be here the first week of August. Can you provide any information on where to purchase the greasing tool? Thx in advance....
One more question.......Upon delivery should I grease all the fittings or trust that it was done at the factory? Love buying American but there’s a lot of smack getting thrown at Polaris on RU-vid.......😢
You're over greasing for there to be that much grease thrown up against the jnside of the hub. There should be barely any visible grease coming through the seal/dust covers.
You do this every single ride? Geeze just grease them every 6 months and replace 1 when it needs it. You're doing way more labor and cost than just replacing then when needed
