    OEM clutch plate question

    Recently bought a 2007 TW and the guy said the clutch was slipping a bit when cold (but fine when hot) so I thought I'd just replace the clutch friction and metal plates. I ordered new OEM Yamaha plates from Rocky Mountain ATV*MC (where I pretty much buy all my MC parts from) and I noticed the new metal plates look different than the old ones, new ones aren't symmetrical. The parts fiche says "336-16324-00-00 (replaces part #137-16324-00-00)" so I'm wondering two things, are these plates a newer version that are physically different and if so how are they installed (orientation...)?

    Here are pics of the plates:

    Original:

    New:

    ************************************************** **************

    EDIT:

    To avoid having to scroll through the multiple pages for an answer, the answer to my questions were eventually provided by Yamaha USA.

    Me: What is the correct orientation for the new design plates?
    Yamaha USA: Thank you for reaching out to us. These clutch plates should be offset as shown in the image below:

    Me: Any idea what the purpose of the nubs are?
    Yamaha USA: This shape allows more oil to enter between the clutch plates to improve lubrication. Thank you for your inquiry.

    So to sum it up, after installing the first of 5 friction plates in the clutch basket, the first steel plate would be oriented with 'nub' at 12 o'clock position (as shown in image below) then a friction plate then another steel plate with 'nub' at 3 o'clock and so on for all 5 friction plates and 4 steel plates.

    Are they all that way? I’ve never had to do a TW clutch but that strikes me as a defect.

    Yes, all 4 are that way. If you google either the original part number or the superseded one you'll see multiple listings on Amazon and various MC parts suppliers that reference them as the correct clutch plate for the TW and other Yamaha models, and show the one with the 'nub' on one side. I can't find any web reference to questions or installation. Since there are 4 of them I would think the correct way to install would be to orient the 'nub' 90 degrees from each other simply for balancing purposes.

    Thes e are the low speed eccentric torque optimizer plates. They are meant to be aligned together at the nub when oriented this way there is a “flywheel” effect that increases torque for low speed crawling. JK

    Does "JK" stand for "just kidding"?

    yes.sounds good though. Or they could be the crankshaft resonance balancer plates for less vibration at top speed.

    When I first read it I was convinced, you sold me. But then I thought about it for a minute........and I came to the conclusion "NO WAY!" However the "resonance balancer for the crankshaft" sounds like a really good idea.
