Clutch feels out of adjustment may have air in line. How do I adjust or bleed the line. Pedal goes almost to the floor before engaging to change gears.Vehicle has 65,000 miles.It is a B2300 2.3liter, 16 valve 4 cylinder,hydraulic clutch.
Look for the small master cylinder resiviour beside the larger one for the brakes. Take the cap off and check the level, it is probably very low fill it with the type of fluid labled on the cap. The clutch is self bleeding these days, pump the pedle fast for like 50 strokes or whatever it takes to get a firm pedle. Check your fluid level again, you will probably need to add more. now look under the truck for a leak, especially dripping out from between the bell housing and the engine.

for the pedal to go to the floor there is still air in the brake system. Start again starting from the longest line bleeding each in turn to the shortest line . make sure you have adjusted up the rear brakes before bleeding as every time you press on the pedal the shoes expand right out and when you take your foot off the pedal the shoes go all the way back in. adjust them manually and do not rely on the self adjuster as it only adjusts on wheel movement
If the clutch is hydraulic operated, you need to bleed the clutch at the slave cylinder, down on the transmission housing. Bleed it just like you bleed brakes of air in the line-open bleeder valve, someone pushes clutch pedal slowly to floor, close valve, and repeat until fluid comes out valve in a steady stream. Make sure the clutch reservoir is full before starting. It uses regular brake fluid. If not hydraulic, it would be cable operated. Adjust the cable until clutch pedal is right.
The one item I would suspect is the through-out-bearing not completely
disengaging the pressure plate from the fly wheel. If the vehicle is in neutral
and you slowly depress the clutch and release it do hear a singing or whining
sound? Since you cannot adjust the clutch any more the through-out-bearing is
the component which moves the pressure plate from the fly wheel to stop the
power from the engine to the transmission. It is difficult to shift when the
engine is on because the fly wheel is still engaged and powering your transmission.
TO ADJUST PEDAL HEIGHT ADJUST WITH A STOPPER LIMITING THE UPWARD TRAVEL OF THE PEDAL.PEDAL FREE PLAY IS ADJUSTED AT THE MASTERCYLINDER PUSH ROD.IF PUSH ROD IS NON ADJUSTABLE FREE PLAY IS ADJUSTED BY PLACING SHIMS BETWEEN THE MASTERCYLINDER AND THE FIREWALL.ON A FEW MODELS PEDAL FREE PLAY CAN ALSO BE ADJUSTED AT THE OPERATING SLAVE CYLINDER PUSHROD.PUSHRODS ARE AVAILABLE IN THREE LENGTHS FOR THE 310.PEDAL HEIGHT ABOVE FLOOR IS 6.73 - 7.13 INCH PEDAL FREE PLAY IS 0.04 - 0.12 INCH.YOU HAVE CLUTCH FLUID LONG AS YOU SEE BRAKE FLUID IN MASTERCYLINDER.IF MASTERCYLINDER LOW YOU HAVE TO BLEED THE THE CLUTCH MASTERCYLINDER BY LOCATING BLEED SCREW ON SLAVE CYLINDER. REMOVE THE BLEED SCREW DUST CAP.ATTACH A CLEAR TUBE TO THE BLEED SCREW.PUT OTHER END OF CLEAR TUBE IN A CLEAN CONTAINER OF BRAKE FLUID.FILL THE MASTERCYLINDER WITH BRAKE FLUID.OPEN BLEED SCREW 3/4 A TURN.DEPRESS CLUTCH PEDAL QUICKLY.HOLD IT DOWN.HAVE A HELPER TIGHTEN THE BLEED SCREW.ALLOW PEDAL TO RETURN SLOWLY.BLEEDER SCREW TORQUE IS 5 - 6 FT LBS.IF YOU SEE AIR BUBBLES CLEAR BLEED TUBE.REPEAT THE BLEED PROCESS UNTIL YOU SEE NO AIR BUBBLES.DONT LET CLUTCH MASTERCYLINDER GO DRY WHILE BLEEDING.IF SO YOU GOT START BLEEDING PROCESS ALL OVER.HOPE THIS HELP.
Check and make sure you have fluid in the clutch master cylinder. If it is low fill and check for leaks. Repair leaks as needed and bleed system. If fluid was full check adjustment and bleed system, if there is air in the system pedal will go to the floor.
ok every time you open the clutch resevoir you have to bleed the slave ..next hold down the clutch to the floor open the bleeder screw 10 mm bolt and then close it and pick the pedal up off the floor if your clutch is not right the pressure plate is failing most likely on mitstu stuff ...bleed first ..
the problem is that either the master or slave cylinder for the hydraulic clutch have failed, it is always recommended that they both replaced together, u can bleed the clutch but the problem will occur again.
Check the fluid, check for leaks, if there is replace the cylinder or hose and bleed the lines of any air. There a two cylinders, the master cylinder(on the fire wall not far from the brake cylinder) and the slave cylinder(on the gearbox) i think this maybe your problem.
