On an 08 D8 155, Stock all the way, the secondary clutch outside sheeve is exhibiting stree wear fractures and the inside in the same area shows very poor casting quality. Has any boby had this issue? Also, possibly related, I found the front PTO engine mount bolt sheared this weekend and and wonder if the rocking engine motion is putting additional/extreme stress on the secondary.
Secondary Clutch cracking Issues

The Mount bolt is a fairly common problem, MountHorse posted a fix last year. Have never seen (or even heard of) a driven clutch cracking. Could you be looking at casting lines?
I've got some outer surface stress fractures on one as well. Mark em with ink and check em occasionally do see if they are continuing to run out. Also verifies if they are from the castings cooling stretch or if they are a stress related fatigue. Common on all use aluminum parts over time that have heat and vibrations associated to them.
Since SnoopDrag posted this question I will add to it. He is a friend of mine and the sled resides in my garage during the winter and usually I am the one working on it.
The bolt and washer (that hold the clutch on the Jack Shaft) on his driven clutch fail to contact the clutch itself when the bolt is tightened down. There is about a 1/16 of an inch gap between the washer and the face of clutch. I have never seen this gap on any other Polaris and do not believe that is how it should be. Is it possible that one of the shims behind the clutch has broken and fallen out causing this gap? Thanks...Jeff

There is supposed to be a gap.It is there to allow the clutch to float back and forth to maintain proper allignment with the drive clutch.It should be set at 1/16 to 1/8 of an inch after proper allignment with the drive clutch.
Lets see some pics!
Okay, I was not sure, my 2000 RMK has no gap but a little bit of in and out play with the Jack Shaft. This was the first time looking closely at the secondary on SnoppDrag's sled. This was a good day, I learned something new. Thanks...Jeff
Of what? SnoopDrag's bent up lower A-arms that I just replaced
What do you say Snoop, how did those A-arms get turned into pretzels?

Pretzels?
Endless days of bottomless powder searching for the finest mustard I could find!

The cracks on the secondary.
Yea, I figured something to do with the secondary, I was just poking at Snoop. I will wander down to the garage in a minute and try for a good picture. My photography skills rank right up there with my communication skills, which my wife says are non-existent.

Right above the two lines under the word team.
One either side of the nut, not positive these are cracks but they look like it.
I keep threatening my buddies to sell their sleds from my garage, it is half full.

Hmmm.
I hope its not lost on all of the riders out there how cool Polaris guys are! Notice the hospitality? Artic Cat, Ski-Doo, and in the way back, an'81 Yami 440 Exciter that goes bullets! It sure is nice of your Polaris' and their attitude to share the warmth? Tall snow makes strange bedfellows.

I think those are casting marks. My Team Secondary has those EXACT same marks. clean the clutch and they are a little more obvious.
I think the two on either side of nut are probably casting marks. The other one I can put a utility knife blade in, we will keep an eye on it. Does your clutch have one in the same place as the first picture? Thanks...Jeff
Check to see if your camera has a "Macro" mode. That allows you to zoom in really close. You can actually take pictures of the ridges of your fingerprints with most cameras using Macro.
I will do that, thanks for the tip. Looking now.....
While you're looking for your glasses, put your hearing aides back in so that you can hear the phone ringing!

You are a funny guy, I don't need glasses and I am not getting any hearing aids. Some of us were out doing man work tonight, you were on the phone when the page went out.
It does, cool! You are right about the ridges too. Thanks for making me dig the manual out.
