2008 SL

as of 2016-08-23 my car had done 107,894 miles on its original clutch

at that point snapshots were reading between 5.4 and 5.7 mm "worn"

and the TOB was leaking, leaving me with no 1st gear above 90 deg F,
no 5th gear above 100 F, and occasional engine stalls on 1st-to-2nd --
a bit challenging to drive on my 1k mi road trips to the Sierra Nevada

I made it to Concorso... and (with a lovely round of stalls when exiting
the golf course onto the city street where a bunch of folks were filming
cars as they left) back home... and to the shop for the big one, at last!

the old clutch still had a tiny bit of life left: the groves where still there
except for a few bald spots on the outer edge -- with road trip drives I
could have made it for another 1-2k mi i.e. to 110k mi total... which is
exactly what the regular E-gear snapshots were predicting for years

went with a factory rev F clutch, a new TOB, and a new position sensor

the replacement job went smooth, as expected, performed by/at LGLC

I was able to watch the installation of the clutch assembly and the TOB
in person, and take lots of good pics/vids in the process -- thumbs up!

immediately went on another 1k mile road trip the next weekend...

so there you have it -- ~108k mi on my original/1st rev F clutch

onward! ...to 200k miles

 

Extremely impressive, without a doubt. The clutch discs seem to wear unevenly surface to surface, with (1) of the inner surfaces wearing the most. Such must be the case with your clutch assembly as well, since that outer disc does look to be in remarkably good condition!

I should take a closer look at the inner surfaces -- I have that old
clutch sitting in my garage, ready to be turned into a coffee table.

I'm also curious about the spotting on the pressure plate: it does
seem to cluster around the upper right quadrant (in the pic) near
the direction of the pilot hole (=small hole, near the center bolts).

You would think that there should be even wear here (=spinning),
especially after some bedding-in time (a la brake discs and pads).
But apparently not. Mmh. Let me go research this some more.

 

That is truly remarkable. Well done sir. On my personal cars, I generally see about 1MM/10k miles but 100k is unheard of. Great job.

 

Great to see people driving these cars!

 

How much freeway driving do you do?
