1935 Chevy Clutch Care
The dry disc type clutch requires very little care during its life.
There are two very simple and easy adjustments that can be made
to maintain clutch efficiency and assure longer life. One of
these adjustments is for floor board clearance and the other
for the amount of travel that the clutch pedal has before the
clutch begins to disengage.
When the throwout bearing begins to squeak, the toe board and the
plate on the top of the fly-wheel housing should be removed and
the oil cup on the top of the throwout bearing filled with a good
grade of heavy engine oil, or a light transmission oil, being careful
to keep this oil from the other parts of the clutch.
