I brought my S60R to a shop to replace my slave cylinder. He informed me that i should also replace the clutch and flyweel at this time. I replaced with stock clutch and a used dual mass flywheel. Clutch slips at 4000 rpm at half throttle. Shop did job twice and cant figure out why its slipping. It was the original clutch with about 100000 miles on it with no slipping. I bought the car used with upgraded parts IPD software, 3 inch exhaust besides that im not sure. Mechanic told me that original clutch wasnt slipping because the bellhousing had brake fluid in it. What should we do?

Lots of variable at play here. Are you using the correct DM flywheel that you purchased used? What model year is your S60R? Did you reuse your original clutch or buy a used or new clutch disc/pressure plate?

Dual mass is correct. 2004 S60R New OEM clutch kit with pressure plate.
There are two dual mass flywheels used on the R, depending on your engine's serial number. You should make sure you found the right one. One has a deeper recess cut into the flywheel, where the clutch disc mates when assembled.

Also, was the used flywheel resurfaced at all?

Was the clutch disc properly installed using Volvo special tools? You must used a pressure plate compressor and a clutch disc self adjusting mechanism tool.

Get ALL parts new. It's not worth it to re-do over and over again. Providing the release mechanism/system is working right and the system is bled properly, irregular wear on the flywheel can cause slippage. Sorry to hear of your troubles.

There are 2 OEM clutches for the R and they switched when the AWD went to pre-charged rears. Buying the wrong clutch will cause the presure plate to slip like you are discribing.

Look at this photo, 04's and 05's get the one that looks rusted. The 06+ get the one that looks shiny. The different is the clover shape bar on the silver one:

What are your ideas on brake fluid causing old clutch not to slip?
Fluid contamination of any type that is likely to be found in your engine bay will only cause the clutch to slip more! There are wet oil immersion clutches,often used on motorcycles, but this is NOT ONE!

I call bogus on any such claim as brake fluid causing the old clutch NOT to slip.

Others have nailed the problem, you must have the correct components or you will experience what you have.

Also regardless of your mods, a new clutch will not slip at half throttle, 4000 RPM.

I am a fan of the stock clutch assembly myself, but others prefer aftermarket.

What sites are you looking at? Because I believe KillerB is correct.

After a couple supplier sites, I was thinking the same thing, they were prob not reputable.... But then on iPd?

http://www.ipdusa.com/products/8841/120114-clutch-kit-2004-2005-s60r-v70r


There is another clutch post that is newer where the poster had installed a Sachs kit... Wonder if this this an issue
I would put less emphasis on the photos and more emphasis that the correct part numbers are ordered.
Since your car is a 2004-2005, you need clutch kit with part number 30783258.

Currently, Sachs does not offer an aftermarket clutch kit that will fit the 2006-2007 models, within their North American distribution market.

Thanks George.

Your single mass flywheel fits with this kit correct?
