    Unhappy Fix for Clutch throwout bearing howel?

    Just finished with install of all new parts from MSA---
    For a early 73 240Z:
    Stock clutch
    Pressure plate
    Clutch collar
    THROWOUT BEARING----
    Dust boot
    Clutch master, hose, and slave were replaced a few months previously with new parts. Worked fine until the clutch disk lining finally wore out and it would slip under acceleration.
    A clutch disk alignment tool was used for the install.
    Bearing howels when clutch pedal is pushed in----sometimes quite loud and annoying, sometimes not so loud.

    Any fix short of taking it all down and redoing with a new bearing?

    Dissappointedly!

    Unfortunately no. How can you apply a fix when the part/area that needs fixing is completely covered by the bell housing?

    It does seem odd that a new bearing would make noise.

    It would not be the first new bearing that I have seen bad. You may want to also inspect the fork the bearing rides on along with the pivot. Either could be bent enough to put a side load on the bearing. I have replacements for both along with the bearing. I will install them as I put the motor back. I do not want to drop the transmission once I am back together.

    Thanks for the replys---

    I knew the answer-----wishful thinking??

    I will reinspect the fork and pivot on disassembly. They looked fine.
    I will also be looking for rough spots on the input shaft.
    I suspect that I have been victimized by a "bad in the box" bearing as a7dz stated.
    It does happen---but

    WHY ME?
