Title: Spring caps touching clutch cover
Post by: Yellow Meanie on March 05, 2009, 02:12:04 AM
Not long after I got the bike, I took off the clutch cover and cleaned it out.
Since then, I have noticed the spring caps have been rubbing against the inside of the cover.
They aren't cutting into the metal at all, they're just touching the paint.

Is there something wrong here? Or have I just tightened up the bolts too much, which squeezed the cover on closer to the caps?

Did you put the rubber spacer back inbetween the cover and the case?

+1  There are brass spacers in the rubber gasket.  I had the same problem with an aftermarket cover.

are you sure you tightened all of the bolts holding the caps on tight enough?  it looks like one of the caps isn't scratched...

Make sure that the nut holding the clutch hub on is tight.

I've seen this happen twice.
One, the owner noticed something was wrong before it got too bad.

The second one, on a 996, owner had no clue.
Spring retainer bolt snapped, retainer jammed against the cover, rear wheel locked and the bike hit the deck.
Luckily it was low speed and damage wasn't too bad, rider was OK.
~$1300 repair.

I couldnt see that gasket making that much of a diff.   I looked at mine and I have a 1/2 inch clearance with that gasket on and I know that gasket isnt taken up a 1/2'' ...   
Tho I have the proitalia clutch cover so i am not sure if it has the same depth is the same as the stocker.

What rubber spacer? :-\
I'm pretty sure it never had one.
I'll just space it with some washers then.

Clutch hub nut. I had it happen to me. It got the point where the clutch hub dislodged itself and froze the clutch. Luckily I was right around the corner about 5 houses from my gf apartment and managed to find neutral before it gave out.

Take off the pressure plate and tighten the giant nut in the middle.

Ouch. Sounds like a good reason to ride with an open cover to keep an eye on things. @ OP, too.

Time to upgrade?

Don't take the easy route of spacing the cover out until you check and make sure that center nut is tight.  Be safe rather than sorry.

i had this problem last time i cleaned the plates...
turned out i had not gotten the index mark exactly where it needed to be, causing the pressure plate to sit out too far.
this in turn caused the spring caps to rest against the (open) clutch cover.

luckily, i figured it out before i fired the bike up

Ditto ..........this happened to me after a dealer did not torque the clutch up enough , set fire to the cover when the paint got red hot .

Check out a parts diagram - the stock setup has a rubber gasket, about 1/4" thick, that has brass spacers captivated in the gasket at each bolt location. The spacers are what actually hold the cover up, not the gasket.  But, I suspect there is something else happening too, as even without the brass spacers, I don't think my caps would touch.

Side question. After looking closer at the picture I noticed that there is no notched spring post. On my '95 m900 there is a notched spring post to show where the marking on the pressure plate should go. Did the later models not have this notched post?

There is a mark somewhere.  Different manufacturers use different markings.  On the other hand, if yours is working fine, no need to worry.

Absolutely.  If the center nut is loose the results can be catastrophic.

You can't see the notch if the springs are installed.  With the springs off you have to look at the post with the notch then line it up with the mark on the pressure plate. 

I think there is something else amiss besides the spacing though.  I have the DP open cover installed on mine and I am NOT using the spacer and I still have a 1/4" of space before anything hits.  You need to double check the clutch hub nut.

I pulled off the pressure plate and the hub nut is wired in position. There's no chance of it loosening.
Although I didn't check to see if it is actually torqued up. :-\

Make your own open cover.  Take a dremel or similar tool and cut out the front of the stock cover.  Then you can see what is going on.   ;)

I just have to paint it before I show it off to you all ;)

You know I thought about that too but I was like dam unless he had a chop saw sitting right beside the PC (or the PC right beside his chop saw) there really was not much of a chance he did it that fast.
