Rebuilding Blown Polaris 800 Engine and reinstalling in 2017 RMK Pro

[@mikyg8564]

Great video bud. I have an 18 SBA 800HO and was doing a top end rebuilt. I’m familiar with engines but never done a new gen snowmobile so it was nice to watch your videos to familiarize myself with the entire engine, its component and the how-to about it. Thanks.

Great series of videos. Just about to rip in to my 2015 Switchback that has 22,000 km. Your series looks like it’ll be my go to, whether I buy a short block or decide to have the crank and cylinders done separately. I haven’t had the engine out of an Axys before so this is perfect for my needs. Thanks.

Need some break in footage. Let’s hear that new heart wail!!!

Would have been nice to watch it in a slower mode and with a little more explanation. Especially from the beginning when installing the oil pump and the water pump, fly wheel and stator, I thought there has to be installed a certain way for the timing, gap size between the stator and the flywheel, all the new rubber "O" rings rubber bushings you get when you get the new motor. Another thing is I noticed that you put the fuel injectors in after the motor was in. I am wondering if that would have been easier to do before putting the motor in. It's my first time doing this so I am having a little bit difficulty getting everything back together. Especially when I took the motor out and then apart almost a year ago. Tried to label everything and organize things best I could but apparently not good enough. It also would be nice if they would give the size of all the bolts used. Most a metric yes but you have some for example M10x1. 25 and M10x1. 5 etc. The service manual only tells you what to torque them at. Real pain in the Ass lol

Good afternoon! Great video!!! It would be nice if you could show me how to clean the ves valve. And then how to set it up? It will be very helpful for me! Thanks for making these videos, very helpful!

[@themediocregarage]

Thank you! I’ll see if I can do up a video of this for you at some point.

[@rawpoptart2046]

Also dope video.

[@stephrace]

Hello ! great video. Can I remove the starter completely, with the big bolt and an impact, or do I have to disassemble everything as you show when you reinstall it. Do I need to remove it to open the base? I have to open the base to change the water pump shaft. Switchback Adventure 600 2012. Thank you!

Good video! Bought a 2017 xcr 800 last month and unfortunately seized up on my first trip, now I know what I'm in for. Question, who should I send mine off to? Stator side is the issue, piston and head started to melt and the connecting rod seized to the crankshaft. Clutch sides power valve ears broke off too, one ended up in the exhaust, gouged up the cylinder a little. Any advice?

[@themediocregarage]

That sucks! BWC Powersports in Edmonton AB treated me really well and I highly recommend them.

[@ujarneqsrensen8745]

Did you prime the oil pump before starting it up?

[@themediocregarage]

No I didn’t. Pump stayed fully primed while removed. As I installed each line I just made sure there were no bubbles in the line.

[@rawpoptart2046]

How is the motor an 850 the 2017 came with a 800 is it because of the bike man kit?

[@themediocregarage]

Good catch! Typo on my part!

[@rawpoptart2046]

@@themediocregarage lol dang I was wishing you had a way to get an 850 in there

[@themediocregarage]

Lol you and me both!

just put a new top end in my sled and when i started it the oil light and engine light came on as soon as i started it did this happen to hou

[@themediocregarage]

No that does not sound right. Did they go out soon or stayed on?

[@PunisherGamingable]

@@themediocregarage it ran for about 2 minutes and didn’t go away so i shut it down

[@themediocregarage]

Thats no good. All I can think is to double check everything is plugged in correctly but hard to say. Hopefully you get it figured out!

[@Johnye75]

At how many miles should one expect to put top end? Same question for bottom end ? Great vid! Thx

[@fairbanksairriders]

Usually around 3,000 miles for a top end rebuild. 6,000 miles for bottom end but at this point the whole sled is worn out!

[@twisted__axis9435]

Who did you get your motor from?

[@themediocregarage]

BWC powersports in Edmonton. He was great to work with.

[@JMX07]

how has the fix kit treated you?

[@themediocregarage]

I got an awesome 1200km on it and then sold it once the 9R showed up.

[@JMX07]

​@@themediocregarage awesome! Do you remember what brand fix kit it was?

[@themediocregarage]

@@JMX07 was a wiseco durability kit.

[@danielleonard640]

When you gap the new rings, do you remember what you set them at?

[@haydenrichardp3712]

Those look like used pistons.
