HELP! Will an 08 m8 primary clutch fit an 06 m7?

[jdpbassman]

I have an 06 m7 that has a primary clutch that is done for. The only clutch I can find locally (quickly) is a used 08 m8 clutch. Will it work?

 

[minet]

yup

 

[jdpbassman]

So even though the sheaves on the m8 clutch are slightly shorter by about an 1/8th inch I'm not gonna chew belts from riding to high in the sheaves?

Nope - But make sure one of them has the Harmonic Balance Plate, and be sure that you get it put on the one you will be using. You will be sorry if you don't!

So ah what happens when you don't?

??

So bill what's going to happen if you don't put that on? I have seen them taken off and have never seen adverse effects.

Throw those balance rings away, all they do is slow the engine spooling down. They do nothing to balance the clutch.

No ring on my after market primary =disintegration. .. harmonics get out a whack.. your risk tolerance may be greater

 

[sledtahoe]

no ring

Had opposite effect, got new primary put the ring on and was way out of balance with it. It better be balanced with ring or forget it. Yes i toke it off and runs way better.They go about 4k then toast .m7 is on third clutch

What will you be sorry about without the ring? My original clutch on my m7 lasted a bit more than 2k miles, replaced it with a brand new '08 m8 clutch without the ring and that clutch lasted pretty much exactly the same as the first one. Replaced that clutch with a '14 m8 clutch without the ring and so far so good but only have a couple hundred miles on it as I bought a new sled and the m7 became the backup.
