Clutch accumulator replaced, but...

[996TurboUK]

Replaced clutch accumulator, symptoms were typical, stiff clutch before engine started.

 

Anyway, nothing has changed with the new one!

 

Must add: First start-up. I.e. I started it up, tested the clutch, let the car run for around 10 mins (cos that's what I do..!) then off for around 3hrs. Returned to car, clutch stiff immediately (first pump).

 

Accu replacement was straightforward, literally half a dozen drops of fluid were lost, and because I read so on several posts, I did not even bleed.

 

Am suspecting that I may need to allow time / a bit of use for the accu to fill with fluid, but just guessing.

 

Any ideas?

Did you change out the clutch slave cylinder also?

Did you power bleed the system using Pentosin CH 11 S (or equal)?

To echo Loren's Q's...many folks that replace the accumulator also do the slave...perhaps because you are already in there or their failures are somewhat correlated.  I would think regardless you should bleed the system...a little air is bad!

Hi Loren, WRoss,

 

I guessed the accu was bad because the clutch works fine, just that the assistance is lost when the engine is off, which is what I imagine the accu is for.

 

So I did not replace the slave, it looks like a pig to get to so I would put it off if possible! Perhaps within the next year I will drop the engine and do all the must-dos and would replace it then.

 

I did not bleed because several posters said they did not find it necessary and I lost only drops of fluid, and they seem to have had a positive result. I don't really see how the accu can be bled because there seems to be no throughflow anyway? Perhaps I am impatient, I only started it up, let it run, then turned it off, perhaps it will be OK after a bit of usage?

I believe you will bleed it thru the clutch slave cylinder.   Try bleeding and see if it helps.
