It might bolt on but everything inside it wrong. You would have to change the weights and the spring at the very least.

The 01+ 800/900 big twins use a clutch with a 33mm taper vice everything else using a 30mm taper. So short of modifying the PTO stub or Clutch, it will not fit. Also, the 660 four stroker has different diameter, so I would avoid that one also. All the others should work though. There are a couple of other oddballs out there to. Early pantera's had a longer pto shaft, so those may not work either.


Keep in mind you will have to recalibrate whichever clutch you put in, unless you find one that was supposed to go in that machine. I believe the clutch that came in your sled was either a version of the Comet 102c or one of Artco's own models. I am leaning more towards one of Artco's though. I thought Cat went away from the 102c's in the early to mid 80's. Maybe when they went under for a spell.

I have an arctco hex clutch on my 74 merc sno-twister and I asked Bob at Image ent. in Eagle River, WI the
same question. He said that most the newer clutches use a wide belt and the hex clutch uses a narrow belt.
Won't work properly, he said. Not sure if you can take shims out of newer clutches to make them narrow
enough to work with the stock secondary. Changing the secondary usually requires a custom jack shaft.
Image Ent has these custom made to accomodate a modern secondary to match modern primary. These are for Merc Sno-Twisters, but may also work on your sled, since the merc used Arctic clutches. Have to see
if they also used same jack shaft-chain case geometry.
Hope this helps.

'02 on up ZL/ZR's have the 33mm taper, '01 was still 30mm

660's have 30mm as well
