2004 R50 with 200+k miles. Bought used about 4 months ago. Put maybe 1500 miles on it.

Son was driving it and noticed the clutch slipping a bit, enough to tell me to start planning for a clutch. He pulled up to a light a day or two later, let the clutch out and nothing happened. So, he had to push it into a parking lot.

I get there and tried to drive it. Went through the gears and the clutch wouldn't engage. Basically spinning like the clutch was pushed in. Popped the hood and could see the clutch slave moving the lever without issue.

Assumed the throwout bearing went. Didn't figure it was the clutch disc as it didn't slowly get worse, just went.

Just got done pulling the transmission. Throwout bearing looked fine. Lever moving the bearing fine. Little oily inside the clutch housing area.

Pulled the pressure plate (no bent/broken fingers on the plate) and the clutch. All "looks" ok, no oil or scoring. Clutch was made by Valero in 2013. Clutch disc seems a little thin, but not to the rivets.

Anybody know the thickness of the stock disc to compare to mine? Mine is about 7.2mm thick, total.

I'm hoping it's just too thin and that's what the issue is. Because if not, I'm totally baffled at this point.

Hmm! R50. Have you consider the possibility of the gearbox is broken? Since you have it out. Try put in gear and check.

 

With the transmission off, I spun the prop shaft and confirmed the axle housing were turning in several of the gears. At first, I was concerned because i could stop one while spinning the prop shaft, but the realized that would be the case with the differential.
