    Default Pilot Bearing Sound

    Good Morning Guys.
    My Name is Freddy, please help.
    I replaced my Clutch and pressure plate as well as the pilot bearing on my HIlux 4X2 Raider 2005 model 3.0 D4D.
    I am still getting a bearing bearing sound when Vehicle in motion, but when i depress my clutch pedal the bearing sound disapperars.

    What could be the possible problem. I used a Sach Clutch Kit.
    Thanks
    Freddy

    When the clutch is released (fully let out) there is no relative movement between these components:
    • Flywheel
    • Pressure plate assembly
    • Transmission input shaft
    • Release bearing
    • Clutch plate

    they are all rotating as a unit, and the spigot shaft does not turn in the bearing.

    The fact that you hear a 'bearing' sound when the clutch is let out could mean the release bearing is touching the pressure plate forks.
    I can't think of any other reason.

    I think 4eTouareg could be correct: the release bearing is connected/part of the clutch engagement arm/fork, and the release bearing by design goes over the main input shaft



    If the adjustment on the clutch engagement is wrong, the release bearing could indeed be spinning while driven by the clutch fingers.

    Also vote for possible clutch pedal adjustment, where does the clutch pedal take, very early?

    Release bearing could be badly installed too - one clip loose / misaligned etc.

    Release Fork pivot/support.

    Had the exact thing last week on a brand new clutch. A bit of grease and the sound is gone. Heard it briefly again when driving in the wet, but gone now. Search for the 'Sonbessie' sound/effect on this forum.
