Thanks for the video I don’t have my dad around sadly he passed away 5 months ago and he would show me what to do so I am going to fix up my skidoo tomorrow by my self
Dont forget when installing those circlips that the notch HAS to be at 12 or 6 position due to the inertia of the up and down stroke. Could pop out if not and result in catastrophic engine failure and damage.
Is It easier to rebuild the top end with the motor still in the sled? I’ve got a 2003 Firecat 500 and I’m trying to decide whether to pull the motor or not for top end rebuild
"PIP Mark" for the top of the ring. It is usually a dot. Make SURE that the spiral circlip is all the way seated. Oh so the second cylinder has to be done properly?😂 The 1st one doesn't matter.
I just brought home a free barn find, (basement find actually) the tag looks like it says 1999 but doesn't really look like a 99. It's a Jag 440 Deluxe and the engine is seized. Gonna try dumping some oil in the heads. What could the reasons be why it's seized? Moisture in the basement or? What does AFS on the hood mean?
Could be from sitting or could have seized while riding. Could be why it was parked. Moisture could have gotten in if carbs were never drained or plugged. If the spark plugs were out, for sure moisture got in.
@@danofalltrades3567 Yeah I figured it out. I was being too careful about it.. I just heated the piston up with a torch and the wrist pin area then tapped it out with a socket extension with electric tape as kind of protection... anyway Piston changed old sled fired right up... adjusting the piston rings so the cylinder block would fit was a tough with out special tool or w/e haha just used a flat head and my fingers 🤣
You are advising people to use petroleum jelly on rubber O-rings! I suggest you do a little bit of research about that. You will find that it eats away at the rubber. Viewers, this is why you should thoroughly review the repair manual for your machine first and foremost before searching UA-cam because UA-camrs are not necessarily experienced mechanics
This is coming from a guy that has 1 subscriber and no videos. No one made you watch my video. By all means if you have a better technique, make a video and show people. Instead of beating someone down who is trying to help! (Btw this machine is still running.)
Thanks for being so helpful to the sledding community with your post. Says a lot about you as a mechanic. Best wishes.

Going to rebuild my Indy 500 soon, this video helped me a crap ton! Thanks guys!
Pro tip check ring gap in cylimder firts by running the ring threw the cylinder with a feeler gauge to make sure gap is within factory spec
I wish I could find a video on this.
Wouldn’t mind seeing a video on how to drain/fill antifreeze from the engine before and after rebuild 🤔👍
If you rotate the head to get the piston in is there a chance you are moving the piston ring to cancel the hole opening on the piston?
great job guys.....u explained everything good....
Thank you!
great video, thanks for posting!
I'm 16 and a rebuild is needed soon for my exciter 570 this helped give me an idea of what to do thanks

Wait wdym 12 or 6
@@darksilencegaming7749 think of a clock. 12 o’clock is straight up. 6 is straight down
circlips makes no difference on location. They have to be totally seated.
@@chaley9093you're right. But.the ristpin does. I rebuilt a 570 motor. It is running good. I
Have everything
On it is ready
Excellent video gentlemen👍
just what i needed Thanks
if you spin the cylinder dont you also spin the rings front there spot???
Hey I am in the process of installing a 580 in this same chassis
Good vid im glad you ain't painting the engine orange

It’s very possible in the sled and less wrenching.
great video
I have a 2009 arctic cat m6, what all should I replace when I rebuild the top end?
Top end usually consists of piston, rings, circlips, pin and bearing.
@@danofalltrades3567 ok, thanks
yeah good job but i cant really repair the top until i have the engine the track the track rail or guide
not bad but i never run my tourqe right up to 20ft lbs first shot tourqe half way and then up to final tourqe spec. but nice job
Excellent

What kind of piston was used for this install?
Don’t remember? The customer brought me all the parts
Pro x
on my f7 the marks on pistons face to the front of sled ?
Most of the time the arrow on top of the piston point to the exhaust (most)
Anyone know of i video of getting the piston off? I got one c clip from the piston still wont come off... 95 arctic cat 580 ext
Did the top end ever run hot? Wrist pin could be frozen in the piston?

Does it matter what ring goes on top and bottom?
Yes! Should be marked with a T or say top
Thanks
Thanks guys this video is awesome
There's gaskets in mine not o rings
