Throwout bearing pin fell out? (anti rotation pin?)

[saki302]

Hello,

While servicing my transmission (removed to take care of 2 minor leaks), I noticed a pin fell out of my throwout bearing. I assume it's there to keep it from spinning?


Is this a critical part? I tried turning it, but it's pretty solidly fixed in place- I didn't push or pull the clutch arm though.


Should I try and reinstall the pin, replace with a roll pin, or just leave it alone? I assume it was running like this for a long time.


I did find the pin inside the bellhousing on the bottom- it's a solid pin, not a roll pin, which is why it probably fell out.



Thanks!
