Volvo clutch

[JMBT]

All 04 and newer volvo’s I have seen have the hydraulic over air slave cylinder. There is no adjustment on it, it either works or it doesn’t. There maybe be some adjustment on your clutch. If it is a Solo self adjusting clutch, sometimes the little wedges get stuck and won’t let it adjust. There is a procedure you can look up to reset it. It involves caging the clutch housing and tripping the wear indicating lever. Also measure the gap between your throwout bearing and clutch break, should be 1/2”, I think, when pedal is released.
If you need the slave cylinder the Volvo part number is 20857740, and they run between $800 and $1000, depending on which dealer you get them from.
