Sound of grinding/whirring when clutch in - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

After my 5 speed swap I've been having this weird sound coming from down under. It sounds like grinding or so when clutch pedal pressed. The slave is properly bled, I greased the Input shaft, but not sure what was going on. I later replaced the TOB during my second tranny swap due to the previous one being pulled from pick n pull (a hit or miss). Got my second tranny up now and with a NEW TOB and still have that same noise. Rev match and it still makes the same noise. My Short shifter is also stiff but doesn't seem like the likely cause. Someone help a brotha out.

it almost sounds as if it is a super single clutch! OS GIKEN, ORC, Cusco, Exedy etc it will chatter a bit anything that has a floating plate will chatter, if that is the case then it is normal...

Sounds like you damaged the tob during installation.

Appreciate the reply.
I have the Competition White Bunny Kit (brand new), and comparing to my friend's that has the same kit and did the 5 speed swap as well, his does not chatter...
