- This Is the most important of the videos on this stupid compression release that Polaris has sold it shows you how to alter the spring to make the compression release actually function it also shows how this thing works and how to reassemble the spring and the cam and the shaft the Polaris manuals are very confusing don’t Explain this at all
Thank you for the excellent video. The pictures and your slow methodical approach make things clear. I struggled for years with no compression release. I had no idea the solution was so simple.
Wow! You knocked it out of the park! I had give up and carried a extra battery to start mine. But after your video and explanation I was able to get the compression release to work. Thank you.
Good information. Thank you. But please but a camera tripod. 👍
Thank you, sir!
good job I apreciate the video thanks
This would have been a great, useful video IF .... I'd been able to see & hear what you are doing! Next time, please recruit someone to work the camera. Thanks anyway for trying.
I would half to agree with you he mumbles around for 5 mins can’t see the part then you can’t tell what he doing I was hopeful for a good video explaining this but i just took stills of his close ups to try and tell about how it goes . Also did anyone see how wore out that exhaust lobe is !!!
Thanks!
You are totally wrong @ 1:33 when you said "the ball is completely safe, it is never gonna fall out, it's trapped in there for life". I repaired a 2010 sportsman 500 in May of 2022 and that actuator ball had indeed came out of the camshaft!! AND AGAIN, I said it in your other video and I will say it again, YOU ARE NOT SUPPOSED TO WIND THE SPRING TO TIGHTEN IT!! Polaris specifically states that on the instruction sheet they send with a new OEM camshaft, or the compression release will not disengage when the engine starts!!
First , I start my video by identifying MY POLARIS 1998 500. Polaris changes designs like a high schooler changes dresses. The ball in MY POLARIS IS TRAPPED FOR LIFE. SECOND ,MAYBE just maybe by 2022 polaris MIGHT have learned how to make the spring. Obviously they are STILL MAKING DEFECTIVE CAMS .EBAY has page after page of venders selling REPLACEMENT CAMS for polaris. I am a tool and die maker and spun my cam in my lathe. The spring disengaged at 500 rpm, the idle speed is around 800 rpm.This is perfect. Edwin Dirnbeck
@@ed631941. Engine rpm is measured at the crankshaft. The camshaft rotates at half the crank speed. If the compression release stays engaged until 500 rpm on the cam alone then the engine would need to be running at a minimum of 1000 rpm to get full compression. That’s too high. Cam speed is not the engine idle speed.
Why don’t you just put another turn on the spring to increase pressure? That’s a lot easier than trying to remodel the spring, and will probably provide more tension than your un-coiling method. Do you think that would create too much pressure? Or??
Thanks
if you pre-wind the spring you will get way too much return spring tension and your compresion release will not release at idle.. (you can hear it stuck on tapping the valves open when it should be released no suprise this will also effect your abilty to idle and probbly does wonders for the cam follower and the Exhaust valves) the spring return force needs to be very light , that is why he is making such a point as to slightly unwinding the spring so that when you install it will provide just enougth tension to return the compression release back to the dowel pin , But as soon as the machine starts , the cetrifical force on the weight must be enougth too overcome the spring and rotate the rod into the release position. I made the mistake of adding prewind to the spring and had to take it apart again , as it would not disengage the compression release untill I got over 700 RPM
@@brianperkins6121 I’ve learned that the info in this video is entirely wrong. If the spring is modified to increase tension, the engine will run but it makes a hellish racket because the ball beats against the cam rocker. But when installed as per factory specs / spring, it works fine.
In short, this video is full of it IMO.
@@russchastain9375 The issue I have experenced myself is replacement cams where the compression release's spring tension was incorrect out of the box,, the spring tension has to be just barely strong enougth to return compression release weight to the dowel pin , otherwise , the compression release wont kick off after the engine starts , tweaking the spring so that it just barely provides enougth counter torque to return the weight to the dowel pin , '"but" not so much counter tension that the centrifugal force acting on the weight will dissengage the compression release at idle , its quite a delicate ballence , I have also had issues with very weak return springs causing the compression release to not work and the starter being unable to overcome full compression .. the design polaris used is very prown to even tiny issues causing issues with its operation .., his point is correct you cant wind a turn onto the spring its return force will be to high , you have to unwind the spring adjusting its tenson if you run into an issue with its counter torque being to low to spring back the weight to dowel pin , you cant wind an extra turn onto the spring the return force torque will end up being so high the compresion release will refuse to disengage and you will also hear the racket it makes in the process.. you should not have to mess with it at all it should just work but in my findings that has not been what I have run into ,,
need a video on a 02 325 magnum comp release...
How many turns did he tighten the spring ?
I like your video, can this repair on the Spring be done without removing the whole cam from the motor?
Yes
The camshaft looked chewed up on the lob the bike will begin to lose power
P
My ball fell out
I guess take it out and toss it .
