How to change hydraulic clutch hose on 1996 Chevy deisel c3500 series

Is it hydraulic.Or cable operated

Hi most chevy"s are fitted with a concentric slave thrust bearing. This normally creates hydraulic fluid leakage between engine block and gearbox bell housing if not so , check hydraulic pipe lines for leaks. bleed system and be certain hydraulic pressure maintains .If problem persists check and replace clutch master and slave or might be a rare case of a faulty pressure plate.

It sounds like the clutch is not disengaging when depressed. What is the year make and model? It most likely has a hydraulic clutch. Many vehicles have the clutch slave cylinder inside the bell housing of the transmission. This means that the fluid line to the slave cylinder was removed to remove the transmission. If a new slave cylinder was installed when the clutch was replaced (this is a good idea to do when servicing a clutch with a bell housing internal slave cylinder) then the system will need to be bled to remove air from the system and allow the clutch disengagement to function properly.

It's a manual transmission, then? If it is, your clutch is not working. You need to check at the transmission's bell housing to see if the clutch pedal being depressed causes the clutch fork to move-either forward or backward, it should move about an inch with the pedal pushed to the floor.. The clutch pedal will either be cable operated, or it will be a hydraulic clutch with a clutch master cylinder on the firewall, and a steel tube going down to the bell housing, where a small "slave cylinder" operates the clutch fork.

If you see the clutch fork move a fair amount, at least an inch, then you probably need a new clutch disc and pressure plate. A clutch job means removing the transmission to replace the clutch.

If the clutch fork does not move, either the cable has too much slack-for cable operated clutches, or the hydraulic unit has a problem-for hydraulic operated clutches. One of your hydraulic cylinders may be bad, either the clutch master cylinder or the slave cylinder.

Do you have a hydraulic operated clutch? The slave cylinder for a hydraulic clutch would be on or sometimes inside the bell housing. Some ford and chevy trucks put the slave cylinder in a very difficult to reach place-the transmission has to be removed to service the slave cylinder. Most cars have the slave cylinder mounted on the outside of the bell housing. If they leak, replace or rebuild, although those internal slave cylinders I think can only be replaced.

The slave cylinder will be mounted on the bell housing and will push on an arm that comes out of the housing. It will have a bleed nipple (same type as on the brakes) at the end of the cylinder near the rubber hose attached to the cylinder .. (This is relevant if the clutch is not cable actuated). Regardless of wether it is 2WD --4WD or how many drives it has the clutch slave cylinder is attached to the bell housing and pushes on the clutch throw out arm in the bell housing. The bell housing is that section between the rear of the engine and the front of the gear box and houses the clutch assembly

The clutch master cylinder is located on the firewall in front of the clutch pedal and has a solid plastic line (hose) that runs directly to the clutch slave cylinder which is located inside the bell housing of the transmission. Unless it has rubbed against something and developed a leak, which is very unlikely, the leak will be at the slave cylinder and drip from the front edge of the bell housing where it meets the engine. This is a common problem with older Chevy trucks and the best fix is to replace the entire hydraulic system with a pre-assembled unit available at most parts suppliers. These units come with the master cylinder, hydraulic line and slave cylinder with a new release bearing (throw-out bearing) and are pre-bled and full of fluid. Replacing just the slave cylinder is a major job and bleeding these systems have been known to drive people crazy. Replacing ALL of it aint much more work and saves your sanity not to mention all those dirty words.

get a service manual on CD over on ebay for about 5 bucks. jack car way up, drop the drive shaft, disconnect shifter and clutch linkage, unbolt the bell housing from the transmission and remove, unbolt pressure plate and take off flywheel, have flywheel resurfaced and reinstall, install new clutch and pressure plate, replace throwout bearing, put transmission and bell housing back in, connect shifter linkage and clutch cable or hydraulic, put drive shaft back in and you are done.

you will need to replace the clutch release cylinder

Your truck has a hydraulic clutch , that works just like brakes. A master cylinder connected to the foot pedal sends fluid to a salve cylinder inside the bell housing. If there is any air in the lines , the slave cylinder will not move far enough to disengage the clutch. The lines can be bled of air bubbles much the same way a brake line can be bled. Hopefully this is the problem. A worn out Master cylinder is not too big of a job to replace , however , on your vehicle the slave cylinder is inside the bell housing of the transmission , and replacing it would require removal of the transmission. If you are not loosing fluid out the slave cylinder it is probably ok.
