Old Guy I see it now. The yellow tinted photo shows a belt drive water pump and radiator hose and I see that the fins aren't as long as I thought.
From my notes: John Deere ran the Liquifire 440 from 76 to 84.
76-78 was a Kioritz 440.
79-84 was a Kawasaki 440
76-81 the drive clutch was a JD Comet 102c
82-84 the drive clutch was a JD TR-800
I'm not clear if the drive clutch is original to the JD engine or not. It looks more like a Comet than a Arctic Cat.
Can't help much on the info on the driven. Arctic Cat used various drivens, St Lawrence/Salsbury and eventually made their own.
Its iffy to mix CVT parts but since you already have the stuff I guess its try and find out.
Which pulley is in front wont matter but they have to be orientated right. I don't understand your comment that the first one was on the other way and tore up?
