I have an Arctic cat 1991 ext 550 special and would like to attempt a track change. Do I need any special tools to do this and is it above the average joe's ability. Do I need to pull the jackshaft along with the secondary clutch to do this ?
Yes with a few basic shop tools you should be able to do it.
The secondary clutch must come off, but you don't have to take it apart. It should come off the shaft relatively easily without a puller. Take the speedo gear and jackshaft bearing out. Take the chaincase off, use rags to catch the chain oil. Drop the rear skid (suspension). Slide the jackshaft to one side (this can be tight) and remove. Track should be free to replace in reverse order.

I had never changed out a track, but I just got done changing mine out last week, and other than having the wrong length at first, everything went fine. No special tools were needed on mine, I had a chain hoist to pick up the rear end, and check for clearance if your lugs are bigger. I went from about a 3/8" (no kidding) lug to a 7/8" and it made a big difference in traction, and was worth the $200 I paid for a used track. Good luck!
Bman, why are you taking the chaincase off to change a track? How do you feel its nessesary? I'm just curious! In my experience, when you remove the speedo side bearing and the lower gear off, the shaft will slide right out of the case side bearing. and you just tip the driveshaft down and out it comes.
You must remove the chaincase cover and the gear that is bolted to that end of the drive shaft. Without doing this you will not be able to slide and remove the drive shaft. It is usually a very easy thing to do, and you should have no problems.

I am attaching a link to RV Sports in Thief River Falls MN. you might want to check them out. They are selling Cat tracks pretty cheap. I paid under $100 for a new one for my 88 ElTigre last year. It was a little dirty and had some surface rust on the clips but after a short ride it looked as good as a full price track. I think they had these sitting on the ground in a pole barn or something like that.
It's not very tough changing them just takes a couple hours.
bman-triumph& hotrod are all right, the chaincase must come apart, otherwise you will be struggling, and the driveshft will not move enough to free itself. wether you have 4 drives or 2, chaincase must be taken apart, or at least the nut on the lower sproket must be removed
O.K. I get it now. He's meaning the chaincase cover....Right? I mean its obvious that you must remove the lower gear on the case side. and you gotta take the cover off to get to it. I'm sorry I was getting to particular on terms. Its a German thing!!!
