Weird Clutch problem

[ADCD875]

I have a manual 1991 318is. Just put a new rebuilt engine in. Also put in a new clutch, pressure plate, throw out bearing, etc. Everything fit fine and engine starts just fine. Until I decided to move the car. Started the car and pushed the clutch in... Awful grinding noise. This grinding only happens when I fully depress the clutch in. So, I dropped the transmission and found that the fork (cyliner side) was grinding onto the surface of the pressure plate. Checked all part numbers and pressure plate is correct (SACHS # 3082 895 201). One thing I noticed was; around the fork guide (opposite side of the clutch cylinder) was grounded (but not new).

What do you all think the issue here is?
Why suddenly the cylinder would push the fork too much into the pressure plate?

Thanks for any ideas!!

Might you have the wrong throwout bearing?

Thanks,
The new throwout bearing was too loose so we used the old one. Maybe that is it?

Reusing the old TO bearing shouldn't be the cause unless it was bad.

Did you remember to put in a new pivot pin & retaining spring in the bellhousing? It's the little plastic nub that pops into the tranny, the fork goes over it and then the wire spring holds it down.

Otherwise, I would have to assume that you have the wrong PP. Is it the same overall thickness as the old one?

What did you mean by "around the fork guide (opposite side of the clutch cylinder) was grounded (but not new)"?
