Clutch not working

Recommended Posts

Hi guys, I recently bought a 2003 911 Turbo with 47k miles. After 2 week of usage the clutch is not working, I can't shift any gear and the clutch pedal is so loose that goes all the way down. I researched a little bit and notice that the clutch accumulator reservoir tank was empty, so I pour some pento chf 11s but still no gear engaging. I pressed the clutch pedal 35 times and still the same. right now i just can't move the car. any advised will be appreciated.

There was some case in the past were the clutch fork was broken. One way to see it, is to remove the starter and with a mirror there is a possibility to see a little bit of the fork movement. Also a slave cylinder failure is possible especially if there was no oil in the clutch reservoir..... The top part on the first picture and the location of the slave on the second picture... Remember the steering pump pressure is used for the clutch operation. Take a look at you steering reservoir to see if the level is normal.

Thanks for the information! double checking the sympthoms looks that the master cylinder clutch failed. I had not pentosin leak in any area but still no pressure in the clutch pedal. When the engine is on no gear can be shift, but once the engine is off then I can shift to any gear without any problem.

It is a possibility but my concern is where all this Pentosin went to, since the reservoir was found empty???? In the past we saw many Pentosin migration that was cause by a faulty slave cylinder. But your case seem different. To be honest with you I did not see a clutch master failure so far but a mechanical part can fail! May be , since the reservoir was empty, you should try to bleed the system....And do a very good leak check....

I had great news! I just fixed!!!

I came back and started to inspect the master cylinder and the reservoir area for any leaks. No leaks were found in the reservoir area, so I went inside the car to take a look of the functionality of the master cylinder clutch and everything seems to look right until I started to hand pressed the clutch pedal. I noticed that the master cylinder did not returned completely to the forward position, so I manually pulled the clutch pedal and felt a bit of pressure ( the feeling was like if the master cylinder was jammed ) then I pressed the clutch pedal a few more times and voila! Started the engine and the shifting was even smoother, made a test drive and works perfectly.

Good job! But keep an eye on the clutch reservoir level, it should not become so low....

Seems like if the clutch reservoir was that low that there must be a leak somewhere or bad accumulator.

Well the previous owner advised me that I had to check the clutch reservoir every 4 to 6 months, apparently he didn't checked for the past months. I heard that by time to time the chf 11s can be evaporated because it's a mineral oil and since we are in a tropical weather this should be expected, can this be true? Can this be the answer for the missing fluid? I had double checked for any leaks and their no signs.

Good job! But keep an eye on the clutch reservoir level, it should not become so low....

I will definitely gonna have it on the my preventive maintenance schedule.

Thanks!
