I have a 01 venture with 10K on the clutch and it rattles at idle.
How do I get the spider assembly off the back half of the clutch to replace the bushings?
I've looked around, but couldnt find any info
 
.. Cool. I have a polaris tool that i can make work.
Still not 100% on what way to loosen it, clockwise or counter clockwise
and what you do with that split ring thing when putting it back together
 
If you dont have any tools you can do what i did and stick 2 pry bars through the clutch and make sort of an x pattern with them." this is much easier with 2 people" Heat up the back of the clutch where the sheave threads are with a torch. turn clockwise and thats it! to keep the clutch from turning install 2 screws on the back side of the clutch where the threaded holes are and mount it in a vice. Be careful not to hit the weights with the pry bars.
 
The thread on the primary clutch halves are a left-hand thread, that is clockwise motion loosens the parts. The threads have loctitie on them so a bit of heat will help break down the loctite bond. The split ring parts come out as you loosen the spider from the clutch half. When you reassemble the parts, definietly use a small amount of blue loctite. The Yamaha "grunt" tool has a square opening in the end of the "wrench" which allows you to use a torque wrench. I have never reassembled the parts "by the book" with the torque wrench. It takes a fair amount of torque to disassemble the parts so I give them a healthy amount of torque upon reassembly. before reassembling the parts, I chuck the clutch halves in a lathe and polish them with 320 grit sandpaper to clean them up and give them some texture.

Thanks for the offer Scott, but i got it apart..
The thing is full heat cracks and its gonna cost a bucket of cash to rebuild.
Im thinking of putting a Comet 108exp on. Any thoughts?

You need primary? I have a couple would let one go for cheap.may need to be re-bushed that's about it. I'm in central new Hampshire
 
dont use a comet if your going to ride the sled for long. they rust up fast.
used clutch should be 150-250 depending on condition. or you can just buy the two sheaves.
when you put the thing back together, use the three slide bushing from a four stroke with the o rings, will take up slack and it wont rattle again.

From a Comet 108EXP owner that's the worst idea you could possibly have. If I hadn't found all the overhaul parts for mine super cheap including the spider tool i'd have replaced the hunk of shit with a stock Yamaha one. I am hoping I can get 2-3 seasons out of the current overhaul on it and then I'm going back to an OE Yamaha primary.

The comet's are junk and hard as hell to find parts/weights/springs for without taking a large chunk out of your wallet.
