I recently installed a new set of clutch discs in my 2008 RK.
It was the Screamin' Eagle performance clutch disc kit. Part # 37980-10.
This is supposed to be an upgrade to the oe clutch discs.
When I removed the old discs I noticed the first two discs that were installed into the clutch basket were narrower that the rest. They are the damper spring seat (1st installed in the basket) and the damper spring (2nd installed in the basket) followed by the friction discs and plates.
Ok, so the directions say not to reinstall the damper spring seat and damper spring. And goes on to say to install a friction disc 1st then a plate and so on.
There lies my question!!! Shouldn't a steel plate go in the clutch basket 1st so the friction disc is not against the aluminum surface of the clutch basket???
Either way, I followed the directions and did not reuse any old steel plates as the directions had stated.
Seems to me the friction disc will wear down the back seat of the clutch basket, but I followed the directions, test drove it and it seems to be ok.
So should I have put and old steel plate in first to protect the rear seat of the clutch basket or not???
Can I expect an early clutch failure the way the directions said to install the performance clutch disc set, or will it be fine?
I'd be on the phone with the dealer right now asking that question, but it's Monday and they are closed!
So if a HD Tech or anyone who has installed this upgraded clutch (part # 37980-10) can help I'd appreciate it!
It's a peace of mind thing.
