Clutch Life?

[ZiMMie]

how much more Km is left in this clutch?

Post a pic of the side, not the clutch faces. Friction discs are just like brake pads, the life is pretty much determined by the thickness.

Looks like quite a bit of friction material left on that disc- but that's not the only determining factor in clutch life. If the driver rides the clutch pedal, it can wear out the pressure springs on the pressure plate so that even with alot of friction material left, the clutch does not have the holding power it should.

All that aside, if you've got the tranny out, you should at least replace the disc with new, since most of the time and trouble involved is in getting to the clutch- not the clutch replacement.

IMHO.

measure the distance from the rivets to the friction surface itself, 99% of clutches i've seen / delt with start new with about 3mm's of actual material from the rivets so you know if you've 1mm left the clutch is 2/3's worn out, so say the clutch is 100,000 miles old you've got about 50,000miles of driving left depending on the operator and the abuse it's put up to. also check the fingers on the pressure plate for wear, if they look worn replace it.

there is no reason to drop a tranny only to put a used clutch back in. just get a new stock one, they aren't that expensive and it will save a headache down the road..

Minimum thickness is 19/64" for OEM disc. Aftermarket may use thicker rivets and have less usable friction material. I agree that the disc looks practically new from the photos. I'd use it - a new one knocks out a $100 bill.
