If i have the updated clutch for the 03 GTX SC with 40-50 hours on it i wonder if it would be worthwhile to change out the clutch this winter with the 06 model since i'm gonna have it apart.

I have the same question, since I`ll be adding rpm`s and work to the pump. I was thinking, do the shaft kit the same time doing the V imp. Alot of people say if it`s not broke don`t fix it, but if your modding something wouldn`t it make sense to tighten that up to!...PR...

Not to mention the headache grenading a clutch first thing next season would cause.

1st post after lurking for some time- so first thanks to GH & friends for the site- it has to take some work and is much appreciated.

Now- to the '06 kit- is this kit the same as the RR clutch kit? Does it come with a HD shaft? For that matter does the RR kit come w/ shaft or is it sold separately? Has SD changed the diameter of SC shafts on recent model years or are they all the same?

What diameter shaft did Bomb give me when they sold me my SC? lol!

Sorry about all the questions- but thanx in advance for any answers. Vic

Welcome to the forum!

The 06 SC rebuild kit is pretty close to the Rotax Racing heavy duty clutch. It uses thicker ceramic disks, but not quite as thick as RR's unit.
The shaft in the 06 rebuild kit is not the thick heavy shaft you get with the RR unit.

For basically the same price I would recommend you go with the Rotax Racing heavy duty setup.

Thanks, GH. The reason I ask is I'm thinking of freshening up my stock RXT this winter- it's got about 80 hrs on it.
It looks though, that alot more tools are required when changing the SC shaft. Also the manual states that when removing the shaft- the bearings should be replaced. Any input on this?
I figured just a spanner wrench to replace the stocker. Have you guru's settled on a slip moment as of yet? Definately going to use an accurate inch pound torque wrench there. Vic

Both the 06 and heavy duty setup from Rotax come with replacement bearings.

My slip moment is right about 8-9 ft lbs and my clutch is holding up fine.

Do all the kits come w/ new shafts as well? Is replacement of the shaft recommended whenever the clutch washers are replaced?
