what mileage did your Clutch slave Cylinder give up at?

[T5R92011]

What are the advantages of CSC over a regular external slave cylinder?

It boggles the mind that on something like a Honda accord, the slave cylinder is so accessible it practically high-five's you when you open the bonnet. 10 minute job. No reprecussions.

But on the Volvo? £1,000 onwards, Sub-Frame removal, DMF replacement, whole clutch replacement......

Stupid Stupid design, putting something that is guarenteed to fail INSIDE the gearbox.

Almost everything made in the last 20 years uses a CSC, including Hondas. Volvo switch in about 1997 on their FWD cars.

My understanding is that it allows a higher ratio for a lighter pedal with throw-distance being limited by a fork. Given that weight (and torque) is climbing ever higher, the clutches need to have higher clamping force, and hence higher release force.

But yes, they're a huge pain when they fail.

Big thumbs up on the 360 Turbo btw James,
had a GLT decades ago and toyed with fitting a Turbo motor from a 700?

I gather it was never a factory model?

Great car, but sadly got rather frilly so i derby'd it...

My concentric slave cylinder failed in April this year at 152'000 miles and of course when it was the most inconvenient time.

I had just refueled and went to pull out of the garage, pedal went the floor so I pulled the pedal back up with my foot but then the clutch engaged by itself and then I knew straight away what had failed.

I got out of the car and there it was, fluid pouring out of the small drain hole at the bottom of the gearbox.

What I will say though is that I did have warning signs prior to it failing, and these were intermittent in the form of a rough bearing sound when the vehicle was started from cold and finally the week before failure it had a squeaking noise that only went away when the clutch pedal was pressed.

I had my vehicle recovered to Volvo for repair and asked them to fit a replacement dual mass flywheel, clutch kit and csc, the total cost was £1700.

OK, I am a V40 owner currently considering buying a used S60

What should I watch out for with the CSC? and its it a guaranteed-to-fail-eventually part (like the worthless thermostat volvo fitted to the petrol S/V40) or just one that sometimes goes?

Its odd as this issue is unheard of on the V40/S40 forum despite our cars using the same engine family, same gearbox and presumably similar hydraulic clutches

The thought of buying a £1000 car then being faced with a repair bill of the same magnitude is concerning: it makes me wonder if all the cheap S60s around are cheap because the owners realised the CSC was going....

You want a cheap s60, well there isn't such a thing. There are loads of issues a list longer than my arm that would cost you a fortune to repair. The s/v 40 cars as you know are hellish reliable. If you want an s60 save and spend a little
More because you will get a better car. I like my s60 but if I couldn't repair it my self then ownership costs would been through the roof. My slave started to leak but then stopped so I'm currently risking
It. There a very common failure on these cars and 1000 pound plus repair.

An interesting thread.

V70 2.4T. Twelve and a half years old. 116k miles. Still on all the original drivetrain components.

Reading the thread though makes me wonder whether to bite the bullet and preventatively maintain the clutch assembly. I trust my village garage completely - and they are also within walking distance of home - so will ask them to price:

> Replacement of clutch and slave cylinder with Luk or Volvo boxed items (whichever is cheaper)
> Replacement of DMF at the same time if seen as necessary when exposed to view

The car has been BSP PPC software tuned - with measured massive torque increase over standard - for over 10 years and probably something like 90K miles so I am amazed that the DMF is still apparently in good health with no symptoms of vibration or sloppiness on power take-up.

2002 V70 B5244S2. The clutch itself started slipping though, so I guess it's time for the whole lot.
How can I tell btw if I've got DMF fitted?
And one more thing - I will go for new rear oil seal, but what is "core plug" ?

Its a blank for an oil-way, its got a rubber seal which fails, new one is a modified design i believe.

The engine manufacture YAMAHA thought it would be fun to create an oil leak hazard within car manufacture which could potentially cause a hazard to their other market, MOTORCYCLISTS.

Now that you mention it I recall poking around the back of my old Toyota TA-40 and finding Yamaha on the back of the head. How many engines are they making in their piano shops and is this where the phrase a tune-up came from ?
