is minor pulsation a normal condition in typical clutch operation.
Operating the clutch should always be a smooth operation. If not, something is wearing out.
There is more than reason. A clutch has plates that engage and disengage. The plates can wear out , often mostly due to riding the clutch or other improper operation. The clutch also has bearing and springs- if any of these breaks, the clutch fails.
The clutch bearing for an AC compressor is located in the center of the clutch. If the bearing goes bad, then the clutch is replaced as a whole part rather than changing the bearing.
Can be a throw out bearing in the clutch assembly going bad.
If it is a standard transmission S10 maybe they are talking about the "throwout bearing" which is part of the clutch operation that can go bad.
bad clutch, bad pressure plate, throw out bearing, air in the hydraulic lines...etc
the front end load bearing or other bearing in the gearbox will be stuffed. when you engage the clutch the gearbox doesnt have any drive thru it so stops turning and then you noise stops.
The release bearing on the clutch is at fault. Throwout Bearing, replace the Throwout bearing and check the Fork for Damage.
With just that to go on I would say that your clutch release bearing is going bad especially if the noise quits when you put pressure on the clutch
Hydraulic or mechanical? If hydraulic Check fluid level Check operation of Master and Slave cylinders Check operation of throw-out bearing Check operation of pressure plate If mechanical: Check pedal to see if linkage disconnected or broken Check pressure plate and throw-out bearing
Yes, the clutch throwout bearing is hydraulically operated.
The clutch bearing or " throw out" bearing is going bad and will need to be replaced, take this opportunity to change the clutch as well.
The bearing lets the belt pully free wheel on the compressor input shaft that the clutch is attached to.
