An air assist hydraulic clutch uses compressed air to enhance the operation of a hydraulic clutch system. In this setup, air pressure helps to reduce the force needed to engage and disengage the clutch, making it easier for the driver to operate. When the clutch pedal is pressed, the hydraulic fluid moves to disengage the clutch, while the air assist provides additional support, allowing for smoother and quicker engagements. This system is often used in applications where quick shifting and lower pedal effort are desirable, such as in racing or heavy machinery.
hydraulics work because fluids are considered a non-compressible material. therefore when you put your foot down on the clutch pedal it pushes the hydraulic fluid pressure through the line to disengage the clutch. if there is air in the line the air bubble will compress (gases ARE compressible) and you will feel a "spongy pedal" and you will have to "pump" the clutch pedal to move that air bubble down the hydraulic line before you get a "good" clutch
It probably has a hydraulic clutch so you will have to bleed the air out of it.
Yes the MCI MC5 has Air assist clutch its at the drivers side on the transmission which is a 4speed .
It is likely that you had to dismantle your hydraulic clutch to do the work so.Is there air in the hydraulics?Is the linkage and clutch release bearing assembled correct.Is there a hole in the hydraulicsIf it is a cable or mechanical linkage is it assembled correctly?
There is no adjustment on your hydraulic clutch. Try pumping (quick stabs on the pedal with your foot) the clutch a few times and then push your clutch all the way in. If the clutch works better after pumping it, your slave cylinder is leaking and needs to be replaced. If there is no difference, you may need to bleed your hydraulic lines - if you have air in there, the air will compress unlike hydraulic fluid and your slave cylinder won't have the full range of motion.
When the clutch is in the engaged position, it typically maintains around 10 psi of residual pressure in the hydraulic clutch line. This pressure ensures that the hydraulic fluid is adequately primed, allowing for smooth engagement and disengagement of the clutch. It helps prevent air from entering the system, which can lead to performance issues. Maintaining this pressure is crucial for the proper functioning of hydraulic clutch mechanisms.
Most hydraulic clutch systems do have a bleeder valve.
Those typically don't use brake fluid - they normally use air brakes. Can't really speak for the UK, but in the US, trucks with a Gross Vehicle Weight Rating of 26,000 lbs. or less tend to use hydraulic brakes, while vehicles heavier than that use air brakes. However, many of these vehicles with either manual or automated manual transmissions do use a hydraulic assist clutch, and brake fluid is what's used in those.
if its hydraulic there could be air in your line. bleed your clutch and refill.
To convert a cable clutch to a hydraulic clutch in a Vauxhall Corsa, you'll need to replace the existing cable mechanism with a hydraulic master and slave cylinder setup. This involves removing the cable clutch components, installing the hydraulic master cylinder on the clutch pedal assembly, and fitting the slave cylinder on the transmission. Additionally, you'll need to route hydraulic lines and ensure proper fluid levels in the reservoir. It's essential to bleed the system to eliminate air and ensure smooth operation.
If the clutch pedal in a Porsche Boxster won't work after a jump-start, it could be due to a few reasons. One possibility is that the jump-start affected the vehicle's electrical systems, including the clutch master cylinder or its hydraulic components. Additionally, there may be an issue with the clutch hydraulic fluid, such as low fluid levels or air in the system. It's also possible that the battery or electrical system is not providing adequate power, affecting the operation of the clutch.
