Here's a clutch puller for a Comet 103 HPQ performance clutch for Polaris and Kawasaki ATV's.
You can see if your clutch looks like any of these. AMToqConvert

 

No wonder it was loud.. A worn out Comet clutch that looks ancient that the po stuck on there. If the puller that jumbofrank shows doesn't work,this expensive one probably will. https://www.denniskirk.com/comet/clu....prd/28464.sku IF you can find any numbers at all on it that may help also.Once you're able to get it off chunk it in the trash..The driven clutch I hope is from Polaris. Here's the cheapest ebs style clutch that matches the rear clutch you should have. 180 bucks versus 500 bucks for an oem clutch.https://www.ebay.com/itm/PRIMARY-DRI...laZ3vY&vxp=mtr

 

I contacted Certified Parts Corp, they said:

"Use part number 217336A, this has a 5/8"-18 UNF thread to fit the stem of the drive clutch."

 

Either get the tool or go to a hardware store and get a bolt that size,use an extension if needed and chunk that clutch in the trash..

 

Yup. Thinking the home made route is preferable.

 

This is the driven clutch. Do I need to buy a spring and weights too for the drive clutch? Or can they be reused from the old Comet clutch?

 

Attaching the photo of the driven clutch again.

Still need to figure out if I need to buy weights and springs for the Caltric or Nuche brand clutches.

 

Comet and Polaris clutch parts don't mix. You actually have a choice on a non ebs or ebs clutch as both will work with the rear clutch(IF it's a Polaris clutch.Several Niche and Parts Ace clutches for your model show to be complete with springs and weights. Tear the rear clutch apart. Has 3 rollers if it's a Polaris clutch. If the rollers are in good shape you can reuse them. If it's a Comet driven clutch,who knows,but it would need to be exchanged for any non ebs driven clutch,new or used. Plenty on ebay or amazon. Plus look at the ones I've already posted pics of(One non ebs,one ebs drive clutches) Rollers are#11 in the pic.

 

Looks like the recommendation for clutch puller 216097A was right after all. I can buy the parts for a home made clutch for less than $20. I have to make one more trip to the bolt store to get the correct thread.

The first recommendation from Comet (CPC) was incorrect, the bolt was too small. Now they are thinking the clutch was made prior to 1995, so it will need a ¾-16 thread. Clutch is older than the ATV...

The Caltric guys are saying their clutch has weights and springs included.

I still need to pull off the driven clutch.

 

Most driven clutches are able to be just jerked off. I rarely had to use the driven clutch puller unless the clutch was really rusted on. If it's a Comet that may be a different story.
