Chevy Clutch Problems & Solutions
This is only for Chevrolet Antique Cars
The purpose of a clutch is to provide a means of engaging and disengaging the motor from the transmission and rear axle to permit gear changes. It consists of a cone shaped disk which engages in a recess in the fly wheel. The face of the cone is covered with a leather band firmly riveted to it To prevent grabbing, expanders are placed under the clutch leather so as to present slightly raised points of contact.
The releasing and engaging of the clutch will in time produce the following conditions:
If the clutch takes hold too quickly causing the car to start with a jerk (when the clutch is engaged slowly) the expanders should be adjusted.
The clutch leather will in time “dry” out, resulting in “grabbing” or slipping. Rub a little neatsfoot oil on the leather to soften it. Should the clutch leather become greasy, wash off with gasoline or apply a little Fuller’s earth to it. Do not use sand or other gritty substances to make a slipping clutch hold.
Clutch Pedal Strikes Floor Boards
As the clutch collar wears, the clutch pedal moves backward.Occasionally the movement becomes great enough to permit the pedal to strike the floor board. The clutch, under these circumstances, will not be fully engaged and the clutch will slip.
Clutch Leather Worn
In time the clutch leather will become worn to the point where no adjustment can be made, in which event the only remedy is to renew the leather.
Occasionally the transmission bolts on Model Four-Ninety and G loosen from vibration, allowing the transmission to shift, throwing it out of line with the clutch. This will cause the clutch hub to bind on the transmission main shaft. In this case it will be very hard to operate the clutch in either direction.

Clutch Rattles and Chatters When Released
The tension on the clutch spring when released is carried on a stud, one end of which is flanged to form the ball race of a thrust bearing On Models Four-Ninety, Superior, FA, G, this bearing is lubricated by pressure through an oil hole drilled in the end of the crank shaft. Occasionally one or more balls become worn or broken.On Models FB, T the thrust bearing is lubricated from the transmission.
Weak Clutch Spring
This seldom occurs, as the action on the spring is very light. However, if none of the above conditions are the source of trouble, renewing the spring will usually correct the difficulty.
