I have a 85' 190d whit a manual tranny , when I drive if I touch the pedal I can feel a vibration / pulsation which dose not hapend if I desingage the transmistion in neutral ,I'm thinking the pressure bearing what you gent's think ?
Can I chech the brearing from under the car , I have a reson to lift the car and go under it, going to change the slave cylinder and the master clutch cylinder next weeck aftre part arrive .

That vibration is normal for diesels. Mine does it with a brand new throwout bearing and it didn't do it on my old gasoline engine. Replacing the slave cyl will be very difficult without removing the transmission from the car. Unfortunately you can't check the throwout bearing without removing the transmission.

The fingers on the pressure plate are uneven causing the peddle to pulse. UPneven fingers are caused by uneven diaphragm spring pressure. ( or uneven coil spring pressure on a lever clutch ) No real fix, just drive it and pay attention to slippage.

Be sure that if the clutch starts to slip at some point,replace the clutch very soon.
A weakening / cracked diaphragm spring will loose drive rapidly. ( A thin clutch disc will slip also and is the most common reason for slippage. )
