94 chevy s-10 clutch won't release comepletely after replacement
Replaced the clutch with the proper kit, plate, throwout bearing etc. after reassembly the clutch will not release completely. I can get it to shift into 3rd and 4th but no 1st, 2nd or reverse. I've tried bleeding the clutch 3 times with the same result. please any suggestions would be greatly appreciated
Two things to mind, sometimes when you get a new clutch it comes with blocks in pressure plate there put in there from the factory for shipping purposes, they have to be removed otherwise it will do what you discribe. secound if you got the wrong length throwout bearing will do it to. most likely its one or the other. if you sure everything is right as far as clutch, pressure plate, and throwout bearing, than the only other thing i can say it could be is slave cyl. bad. hope this helps. OLD SCHOOL.

It sounds as though the clutch pressure plate has become weak.
When you press the clutch pedal the release/throwout bearing presses against the centre of the clutch pressure plate. This causes the metal 'fingers' -the springs- on the pressure plate to flex and release pressure on the driven plate - momentarily disconnecting the drive from engine to gearbox.
A weak pressure plate isn't fully releasing the driven plate. If you're going to do any replacing of parts - a clutch should be replaced in 3 units: Pressure plate, driven plate and release/throwout bearing.
Insert a pilot shaft or an old input shaft into the center of the clutch disc, pressure plate, and the pilot bearing in the crankshaft.
With the pilot tool supporting the clutch disc, loosen the pressure plate bolts gradually and in a crisscross pattern.
Remove the pressure plate and clutch disc.
Clean the transmission and clutch housing. Clean the flywheel surface with a non-oil based solvent. Wash your hands before installing or handling the clutch assembly parts. Hold the clutch disc by the center hub only.
Before assembly, slide the clutch disc up and down on the transmission input shaft to check for any binding. Remove any rough spots with crocus cloth and then lightly coat the shaft with Lubriplate.
To remove the throwout bearing assembly: Remove the return clip and take out the throwout bearing carrier and the bearing.
To replace the throwout arm use a / 16 in. punch, knock out the throwout shaft spring pin and remove the shaft, springs, and the center lever.
Do not immerse the throwout bearing in solvent; it is permanently lubricated. Blow and wipe it clean. Check the bearing for wear, deterioration, or burning. Replace the bearing if there is any question about its condition.
Check the shafts, lever, and springs for wear and defects. Replace them if necessary.
If you hadn't planned on replacing the clutch disc, examine it for the following before reusing it. Loose rivets. Burned facing. Oil or grease on the facing. Less than 0.3mm left between the rivet head and the top of the facing.
Check the pressure plate and replace it if any of the following conditions exist: Scored or excessively worn. Bent or distorted diaphragm spring. Loose rivets.
Insert the control lever into the clutch housing. Install the two return springs and the throwout shaft.
Lock the shift lever to the shaft with the spring pin.
You probably have a hydraulic clutch. A hydraulic clutch has both a master and a slave cylinder. The slave cylinder engages/disengages the clutch plate. You might be low on clutch fluid in the master cylinder, or the system may need to bled similar to bleeding brakes. Worst case is you need a new clutch, pressure plate, and throwout bearing. They should all be replaced when doing a clutch job.
this sounds like the throwout breaing is going or gone bad and may have lost it purpose of controling the pressure plate, by not being able to select a gear tells me something has gone bad in the clutch system like the bearing which pushes the pressure plate to release the cluch which allow ****** to stop spinning so that the gear can be selected. the repair for this would be to replace the clutch kit. the clutch pack will come with new bearing clutch disc and pressure plate and if needed a polit bushing, the whining noise was a warning that something in the cluch system was going bad.
Lets start with what was replaced : Clutch pressure plate, throwout bearing,pilot bearing,input shaft bearing, was flywheel cut or replaced,Clutch cable or slave cylinder (whatever is applicable,) Lets see what repair shop says. Depending on what they say they did or didn't do we will take it from there.
keep me posted
It sounds like your throwout bearing is shot. There is a bearing called a throwout bearing that goes against the clutch forks when you push on the clutch, which causes the pressure plate to release the clutch which also releases tension from the input shaft which lets you change gears. Replace that throwout bearing and I think you will find all your troubles gone. Hopefully it hasnt ruined the pressure plate forks. if your pressure plate forks are good there is not need to replace the clutch though if there is lots of miles on it you might choose to go ahead and do it since the transmission will be out anyway. Of course that is a lot more money. the choice is yours though so dont let a shop talk you into it if you dont want to. Cheers.
You must remove the transmission from the vehicle. The clutch release bearing (throwout bearing) rides on the input shaft of the transmission, and is the only part of the clutch kit that remains attached to the transmission upon removal.
Make certain you reattach the bearing retainer mechanism to the bearing fork, so that the bearing doesn't ride on the face of the pressure plate while you're not using the clutch pedal.
