Polaris 570 Motor Rebuild

We finally rebuilt Kevins Polaris Rzr 570 with a Wiseco HC Piston to give this beast 570 a bump in performance. Lets see how it goes. This video also shows how to rebuild the cylinder and time a Polaris 570 motor for others.

[@charlieriggio194]

Perfect extremely helpful video. If this video doesn’t help you rebuild the top end on a polaris 570 you shouldn’t own tools

[@Solitude313]

Haha thank you very much. Glad you found it helpfull.

i have a 2015 rzr 570 with 400 hours onit and all most 4000 miles , change all fluids every 30 hours includeing oil filter and it has run fault less , never fail to start even after being lay up for a few weeks , never used any oil between oil changes , i am very much into maintenence and think it helps alot to keep on top of this sweet little engine as it has to work very hard

Que tipo de aceite debe llevar este motor?..,

[@tgdibello]

This is incredibly useful for me, thank you. Doing an Ace 570 that ate too much dirt.

[@malcolmmcintyre4584]

Awesome thank you so much for sharing your video very easy to follow 😅

[@PeeterPuncher]

For those of you wondering why out-of-adjustmant valves cause a no start, as the valve seats wear from the valves seating millions of times and the slight wear of the cam lobes riding on the buckets, the valves actually sit deeper In the seat which causes the valve stem to rise. The rise of the valve stem also raises the bucket (which sits on the valve stem) and closes the gap between the cam lobe. The loss of the clearance gap will cause the valve to not fully close losing compression through the slightly open valve......almost all car engines use this same design as well.

[@RB-mv4fz]

Awesome video! Thank you!

[@CarlKahler]

Great vid tyvm

[@NotJustAnotherCody]

I appreciate the video had my sportsman for few years 570 .when I get the chance to ride its hard .but you mad it look super easy keep up good work

[@petitogaming5659]

torque spec for cam carriers??

[@fivedogsranch9288]

How much lateral movement should a piston have, if any? My son borrowed my 2015 Ranger crew 570 and smoked the clutch belt. He replaced the belt then started it up and heard knocking in the motor. I got it back and started it and heard a fairly loud knock from the lower part of the motor. Doing the rear down when I got to top end of there was lots of water or coolant in the cylinder, piston top and on the gaskets when I pulled the cylinder off. One burnt valve and I can move the piston side to side quite a bit. Thanks. And your video made the tear down simple! Thanks.

[@Solitude313]

Side to side is ok, Just not up and down.

[@fivedogsranch9288]

Ya, that’s kinda what I figured. Removed piston and sure enough the rod has both lateral and vertical slop. The up and down of the rod is the knock I could hear!!! 😡

[@dustincribb8616]

Also what are torque specs for the cams and Sequence

[@OldGlory1776]

Well done video!

[@Solitude313]

Thank you

[@kyledeleshaw1]

I'm currently doing this. What's the trick for getting the cylinder back over the new piston??

[@BrianSmith-lo3mj]

That is exactly what I was wondering. I know that on a regular engine that you would find in a car or truck that you would use a regular ring compressor but with that engine design it looks like it's a whole different ballgame.

[@CumminsDriver]

Great video. Im curious how much the high compression piston helped power? Also, what octane is required with that piston? Thanks

[@jimsimpson4385]

i have 2015 570 split one side off is the other sidr pressed in the case with crank bearing ?.I can not remove the crank do i need to press out of the case??

[@blackmetalchevy]

good video! Very detail!

[@Solitude313]

+blackmetalchevy Thanks man, Im trying to get better quality and still figuring the whole video thing going.

THANK YOU BROTHER!! GREAT VIDEO AND VERY HELPFUL, I WISH EVERYONE MADE VIDEOS AS GREAT AS YOU DO!! #SUBSCRIBED THE MOST HELPFUL VIDEO ON KZbin!!!!

[@terryallery4608]

terry allery i have a 570 every thing is out including crank is there a place to send the motor to fix or i am looking to buy a new or rebuilt with more power any sugestions on where to buy do you sell them

[@Solitude313]

I dont sell, and I usually just go to the Manufacture Website and get the Part #'s and then Google the cheapest price.

[@TheHondaOutlaw]

Nice video, but i have to ask why not do a big bore, or was it just a want to keep it somewhat stock rebuild.

[@Solitude313]

+TheHondaOutlaw We couldnt decide what we wanted to do. We are going to send off the jug that was taken off for a Big Bore tho so itll be ready next time.

[@TheHondaOutlaw]

Solitude313 Sounds like a good plan.

[@ronaldmcguire1581]

How did you change the piston? Did you have to split the case?

[@Solitude313]

No, all with the top end off. Rocked the cylinder on to seat the rings and good to go

[@jasim1234567890]

What is the socket size for the tensioner bolt for the cam

[@bkeenan85_outdoorlife]

Great build, have a question when doing my rzr 800 bbk, 1 of the head bolts stripped the treadmill. Do you know which time-sert to use? I've heard the Toyota rav 4 could be used. any other comments out there would be appreciated! thanks, enjoy watching your videos!

[@bkeenan85_outdoorlife]

*stripped the head threads

[@Solitude313]

Man Im am not sure to that question haha. I cant wait untill I do my 800 build tho.

[@noahkruetzkamp7122]

2 questions. Did you order that kit straight from polaris website. And is that an aftermarket kit or oem

[@Solitude313]

No, I ordered it through Partzilla and Wiseco and made my own kit.

[@noahkruetzkamp7122]

@@Solitude313 okay thank you

[@williamduke5588]

I have a 2014 Polaris ranger with a 570 in and only 180 hrs on it, It started burning oil real bad not sure what went wrong. I've never over heated and the oil is not over filled (questions I've been asked) I have to put oil in every couple of hours of use, do you think if I just replace the same parts you did it will fix it? I have't heard of this problem coming up with any other 570, also the air filter box is dry so its not sucking it up that way.

[@Solitude313]

william duke Yea kinda sounds like you had some dust get through and ate up the rings. I'd do a top end and have the head reworked

[@Tony-kr8nd]

Hi. What kind of lube you use in 17:11 min of the video?)

[@alexramirez8444]

Does anybody know if I could use the same top end parts for a 2020 sportsman ?

[@davedemme1577]

Great video I’ve watched it several times. I rebuilt my daughter Suzuki 400 it’s amazing how similar the two motors are. What’s the most miles you seen on these 570s.

[@Solitude313]

Dave Demme Quite a bit, this one has probably 1000, but known to hit 10k if maintained right

[@kevinmasters7189]

SolitudeCustoms i wish my 03 kodiak 400 had an odometer on it. I had that quad for 13yrs and bought it brand new. I rode the shit out of that thing plowing a quarter mile drive every winter, hauling firewood, pulling logs, going on 30 mile+ rides at national parks several times each year and just riding around the property in general. Still had the same power as the day i bought it and the oil came out just a shade darker than when it when in on the last oil change before i sold it. Changed oil and filter once a year. That was a well built motor. Never changed the belt all those years i had it either. No joke. Only sold it to buy a sxs.

[@kasperkauppi]

my RZR 570 has 21 000 kilometers on it... still running good

[@gabesgarden57]

I have a 570 sportsman with 7500 miles, still running great not many issues besides axle boots and axles.

[@davedemme1577]

Do you think adding an Alba cam chain tightener help with longevity.

[@Solitude313]

Yes I do recommend those. they help with the backlash

[@chrisstepp3114]

Would this be the same for a 15 570 sportsman

[@davedemme1577]

You said that when you were done rebuilding the motor it wouldn't start. So you had to change bucket shims. Any reason why you would have to change them when all you did was install new piston. Maybe cause it was a high compression piston?

[@Solitude313]

No it was 2 different things, it would be hard to start so we did the piston and got a Lil more power thinking that would fix the hard start but the whole time it was the valve adjustment

[@davedemme1577]

Do you think 3000 miles is a lot for this motor. Still runs strong. Not smoking or anything. Just wondering how long till I should do a top end.

[@Solitude313]

It's up there in miles but as long as you keep the Air Filter clean and Oil Changed you should be good

[@MARCO30112509]

Olá amigo eu marco Brasil sabe me dizer qual e a folga das válvulas Escap e Ad.

[@elkbow]

How many hours / miles on it when you rebuilt? Good video.

[@Solitude313]

Maybe 600, but it was really not needed

[@tammypapa1]

ended up being valve's but was your compression low i've the same issue not starting only 101 hour's 2016 rzr 570 let me know about the compression thank's

[@joshuahall7509]

Cleve Caulder was your valves stuck? I adjusted the shim buckets with no luck. Still has low compression I’ve not tore into it past the shim buckets to see why

[@justinrhinds]

I read in the comments that you had to adjust the valves. I have a 570 sportsman that won't start. Trouble shooting and suggestions tell me to adjust the valves but I'm not sure how and can't find a video. Do you have one for this fix or could you give me a summary on how to? Thanks for the rebuild video and any help you can offer.

[@Solitude313]

Kthulus Wrath I have a update video of this motor rebuild that explains it some. Adjusting the valves is kinda tricky and there us a big chart to go by in the manual. Do you have one?

[@justinrhinds]

Hey man doing the same job on a sportsman 570 how do keep it at tdc. I read there is a tdc lock out and you put a 1/4 extension in it behind the flywheel??

Pull the crank sensor and look through that hole

I actually just did the same job you need to pull the stator cover off and then the flywheel and there is a tdc lock out and then you can be perfect with your timing

[@billhambler8310]

I have a 2012 Ranger 500 efi. The oil supply line tore off while riding. Engine ran until I heard knocking, fixed line added oil and started. I now have a engine rattle or knock. Shut it off and haven't used since. What engine component fails commonly fails in this instance?

[@Solitude313]

If its a knock, then the crankshaft most likely. The bearing let go and probably the piston is scared

Hey its a ENGINE not a motor look at the owners manual or the service manual or listen to the manufacture kzbin.info/www/bejne/pYDLf4WfjdF3rM0 How you can read the owners manual, service manual, brochures and advertisements where they ALL SAY ENGINE then spew motor is really weird, you do have a starter MOTOR and a fan MOTOR.
