volvo 66 help
 

Could any one suggest what this unit does or is called? and does anyone have drawing or picures of where all the vaccume pipes go in the engine bay? I have accuired a 66 but it has no pipes connected ony to the cvt

much appreciated

ahh the clutch servo disengage valve :) you might find the gears grind when putting it into gear if this does not work .the tilt switch on the gear lever works this valve which then allows vacuum down to the servo on the clutch housing which is the equivalent of pressing the clutch down on a manual car , this allows you to get the gearbox in gear without the gears grinding when the choke is out . There are only two pipes one vacuum pipe from a T Piece from the inlet manifold and the other goes down to the clutch servo on the clutch housing .

thanks for this..very helpfull..has anyone replaced this with a newer version?
