Just wondering what size wheel bearing greasers fit on the 2020 sportsman 570? Are front and rear same size? Where did you get them? Thanks!

Mine is a 2014 and it takes the 35mm front and 40mm rear. I think polaris upgraded at some point 2017/2018. $17 on ebay for the set. 40mm and 45mm. Will cover you and any utv buddies you may have. Worked great.

Shielded aren’t sealed. Thin gap around the inside race. Oozes out around there.

We're on our third generation of Sportsmans, 2 ea:. 2005 700 twins, 2015 570's, and now 2020 570's. I've never seen greasing the wheel bearings on the maintenance schedule, and never had an issue with wheel bearings. Out of curiosity, what conditions prompt you to grease them, and at what intervals? In Idaho, we're rocks and dust. Is it water and mud over the hubs that necessitate greasing them?

OEM bearings are undergreased from the start!

There are videos showing how the grease tool works, and brand new bearings cut open showing very little grease. It’s an inexpensive tool and worth giving long life to wheel bearings. Yes mud and water riders will need it much more, but all can benefit from it.

I see 35mm & 44mm for 2018, not 45mm. Can someone Please confirm size.

Can someone post the link to the correct tool? And the video for how they do it? I’ve got a 2019, with 1200km on it and now you have me worried I don’t have any grease in there.
Thanks!

Mine had 1,000 mile on it when i bought it and had next to nothing in all 4 bearings. Also dropped the a-arm off the ball joint and not one bit of grease under the boot. Greased them up as best as i could as well.

Water and mud.

My sportsman 570 has a bit over 2000 miles on it and I just recently installed the 3rd set of wheel bearings. This time, I bought the bearing greasers. I was able to put about 18 pumps of grease into the new bearings before they were full.

I really think the bearings should NOT be filled with grease, they aren't designed that way. If you're riding dry conditions and haven't experienced premature wheel bearing failure then it seems like this isn't a product you need. BUT, filling with grease is better than them taking on water and mud which is what happens in short order in my riding area.

Ok, so we have 3 570 sportsmans in the neighborhood. (1) 2017 570. (2) 2018 570 EPS. (3) 2018 570 touring. Can someone confirm the F/R bearing greaser sizes for these machines. And do the 2017 and 2018 machines all use the same size. A link to purchase would also be great....thanks guys 👦

Search for sportsman wheel bearing greaser on ebay. They are everywhere. $17 for a pair. 35mm front and 40mm rear. The 35mm one i got fit the bearing but was too small to go over the axle. Worked out fine because there aren't grease zirks for the ball joints anymore so i had to drop the front a-arm to pull the axle out of the bearing to grease it and then pull the little rubber boot off the ball joint and grease it too. My ball joints were bone dry and a little rusty. Used a needle point on my grease gun to get it in the ball joint and worked it around and then left a good bit in the cup of the boot. The rear one needs a 45 degree zirk on it to get the grease gun on.

I don’t understand the confusion. Doesn’t ^^^ that explain everything. Choose any greaser you like and have them confirm whether it’s for a pre or post 1/15/2018 Sportsman 570/450 build. If they don’t know the difference then find a company that does “know” what they are selling.

So 35mm fits all fronts, ok I get that, but listings mostly state parts for Rzr not sportsman 570, and there is talk about a 44mm tool. The chart u posted only shows the bearing size for after 1,15,2018./ 40mm. the first has no bearing size. So the 35 and 40mm will grease the 2017 and 2018 570's ?
