How to Properly Set Your Throwout Bearing Clearance

Too often a failed clutch isn’t the result of shoddy workmanship or–the excuse heard all too often–excessive horsepower.

Quite often the real culprit is as simple as improper clearances. This is especially true with the hydraulic throwout bearing. The throwout bearing is used to activate the clutch. When you depress the clutch pedal, the throwout bearing extends, pressing in on the clutch fingers.

The problem comes when the throwout bearing is too far from the clutch’s fingers, then you are shifting gears when the clutch isn’t fully disengaged. Or you can have too little clearance which keeps the clutch from getting full engagement with the pressure plate. Neither scenario is ideal.

But properly measuring correct throwout bearing clearance is relatively simple and easy. You can mock everything up and make your adjustments on your workbench or even while the engine is in your car. And then you will have the peace of mind knowing all your horsepower is actually making it to the rear wheels.

    Interesting, will this work with a mechanical throw out brg too? I'm thinking it should

    Yes, the concept is the same. Just make sure you know where the mechanical fork positions the bearing when it is at rest. May not be against the face of the transmission like we discussed in the video.
