Polaris 570 Rebuild Part 3 - Top End Reassemble

In part 3 I show how to completely reassemble upper end of the Prostar 570 engine. This is the same for the Ranger, Rzr and Ace. Now the Sportsman is going to be exactly the same process other then the engine case is slightly different in shape. @PolarisNuts Garage

Rebuilt my whole engine with your videos! Really appreciate it.

[@user-xg9yh6tv6t]

Thank you so much for putting videos together like this!! I just did a 570 rebuild top and bottom watching your video and spot on...she is running like a top after I had an air lock in the coolant system!! Thank you.

[@richardpreiato4600]

These videos gave me the courage to do my rebuild which has sitting for a year and a half.

[@montemania198210]

I’m so glad to hear that. Enjoy your rebuild.

[@chadrwalker]

You are totally saving my A$$ with these videos!!! Keep up the great work.

[@benjaminhathaway377]

Thanks helped me get my 570 engine back together perfectly! Froze the crankshaft overnight and baked the housing in the oven at 200 degrees for 15mins she fell right in! 😃

[@Un4givinSi]

So thankful for these videos. Pulling a 570 out of a new to me ranger and gonna rebuild it for the next deer season.

[@montemania198210]

Glad I could help out. Currently building video library for the 570, don't forget to subscribe for more great content. Thanks for watching.

[@GabrielSturm-cy3fz]

Thanks a lot for making these videos!! They have been extremely helpful for my Polairis 570 rebuild!!!

[@luckyreed1152]

I don't see the video for the stator and side cover install, Loved the trick with freezing the crank, went in smooth as butter!

[@yoreh]

Thank you for your videos. I learn alot. I wish to see a video on the 330 as well.

[@montemania198210]

Your very welcome and thanks for watching. As soon as I get a 330 in I’ll be making videos on it.

[@justinpruitt177]

Great videos, would have liked to have seen references to valve lash since you had to use new cams, but all in all great videos showing this can be done in one’s garage with simple hand tools.

Big hose clamp makes a good ring compressor......

[@phishboy66]

Thanks for the video, do you have part 4?

[@rayaustin2560]

Just replay episode one and go backwards and refer to your manual at the same time.

[@malibu7935]

Thank you for your video I'm having trouble with the starter and the gear it's my first time replacing starter the starter wheel but is the 4 starter on it need some help

[@petitogaming5659]

Can you switch from silver bolts to black bolts and be okay?

[@rightwinggunslinger1]

Thank you! Are these 570s all similar to each other? Exactly the same? Ebs vs SP vs ranger vs sportsman? A 2016 sportsman with goofy noises fell into my possesion yesterday. I have a feeling i will be watching your videos a lot at some point soon. Thanks again. Cheers from central minnesota!

[@amartinez81]

Thank you for this video. Probably a dumb question but I’d like to make sure…this will work for a 2015 Polaris ranger 570 utv ?

[@montemania198210]

Yes it will work

[@lloydporche4790]

I just finished my rebuild and got installed back in the machine Thank you for all your help! Is there a coolant bleeding method! I seen something about clamping off the lower antifreeze hose but the engine run for a little bit shut it off and then unclamp the hose.

[@montemania198210]

That’s wonderful to hear. Yea there is a bleeder on thermostat housing. Open it up while filling system. Close when air bubbles stop coming through. Fill rad rest of the way. Start engine let her come to temp then shut down, let it cool and recheck. Also when starting engine for first time vary your engine speed between 1500 and 2500 to help rings to seat in.

[@lloydporche4790]

@@montemania198210 Thank you it worked perfectly!!

[@chickchickboom324]

Why was one of the intake valve buckets missing when you put it back together???

[@austinrenaud690]

Will you do a 570 valve rebuild with clearances and new seals

[@frankdonato922]

Will the cam chain tensioner conversation kit for the 570 work on my 2019 ranger 500 I can’t find any info on it.

[@petitogaming5659]

is there a way to ensure tdc is being held while engine is in quad? i plan on doing a 570 rebuild on a sportsman, but im not doing the bottom end. engine is going to stay in quad.

[@The_Squad_1967]

Great video do you have a video on adjusting the valves ? What brand of assembly lube are you using and what brand of grey sealer did you use ? Thank you for the great videos

[@montemania198210]

Thank you. I use permatex products. I don’t have a video on valve adjustment yet but will soon. No easy way of adjusting them, if out of spec you need to change the tappet bucket in order to bring into spec. There is a aftermarket company that makes adjustable buckets that u can shim making adjustments easier.

[@The_Squad_1967]

@@montemania198210 Which grey permatex did you use there are several grey permatex sealants to buy. Thanks

[@The_Squad_1967]

I adjusted my valve clearance it was negative on intake side after 200hrs had hard starting when it was cold outside and installed hot cams tensioner starts right up no problem with below freezing temp. Thanks

My engine says made in USA on it not mexico

[@andythurlow9502]

I really think I would keep things cleaner?
