a buddy's 04 rev 800 is due for its 3rd primary. inner sheave splines keep cracking, its getting ridiculous. gov. cup shot now too. like to replace with maybe a polaris primary, since doo's are too spendy at the rate he replaces them. any suggestions? what would have to be done to make one fit on his rev, and is it a reasonable thing to do, or would it really not work as well? anyone else have this happen often?
replace skidoo primary with ???

he doesnt want to spend too much more, thats for sure. he rebuilt the engine last year, just to have it fresh for the year, and the oiler cable promptly broke, so he bought a complete new one. had clutch rebuilt, due to cracked splines, and shop didnt put in new bushings, even though he asked for em. lasted about 20 minutes, and it went again. cost a stupid amount to get it fixed that time, they didnt go good for it at all. now its pooched again. he had new bushings and rollers in clutches last year, but it doesnt last. he does ride lots, and hard, but a bit ridiculous at this point. i really dont put any stock in the local doo shop at all. they dont stand behind their work, and let customers down lots. they just love selling replacement parts. any idea what woudl cause splines to crack that regularly? im not familiar with doo problems, have been too distracted with polaris' for last buncha years.
Putting on a p-85 on a ski-doo is the one of the best mod's for them.. for the money.. IMO... you will have to fit one that already has a ski-doo taper on it.. or find a machinist with the specs to cut a taper into the p-85 to get it to fit.. should be able to find one on here pretty easy
^^agreed.. definatly check the run out.. before you do anything!
yeah! sounds like your talking about me. My hifax are lasting longer than my clutches. I have an 04 skidoo 800 and i am in my 3rd clutch. First time my inner sheave was cracked on the splines, and the outer sheave was cracked which i think inludes the gov. cup. So all new parts where put on and low and behold about 1000 miles 1 year to the date almost... shot again. all new internals and a new gov. cup. Works great so far only a couple hundred miles on her. PLUMNUTS are you sayin my crank is not true? my sled "mountain sled" whitch is wide open on the hills most the time has 4k miles on her. If it was the crank I would think it would snap by now. Please someone let us know because that one hit close to home.
Yep.. out of round crank, or out of balance clutch, or improper mounting of the clutch

A guy doesn't see many 800HO engines with this kind of mileage on them that doesn't have crank issues. Tore mine down with 3000 stock miles on it and the bearings were already chattering real bad in the case.
Definitely check the run out but you won't always catch bearings unless they're almost ready to ruin your case halves. TRAs are usually known for going for thousands of miles before even needing rebuilt. Polaris clutches don't seem to last as long but you can also get them for $250 brand new and they do work wonders on the Doos with the factory Polaris weights.
