Low Brake Fluid Pressure Symbol

Lockpin 4 is resting with full diameter on locking disc 2 . Selector arm 1a is turned when making 3rd 4th gear shift. Locking disc 2 must also turn via the stops of opening N so that lockpin 4 remains in the illustrated position. 5th Reverse Gear Shift Plane 5th Gear Engaged Selector shaft 1 must be pushed in direction of arrow to get into the 5th gear shift plane. This will mean having the face of lockpin 4 partially above opening 0 of the selector arm. If 5th gear is engaged, selector shaft 1...

924 Turbo Ignition Wiring Diagram

The diagram shows the basic ignition timing curve verses engine speed, without the ignition timing changes which result from input from the pressure sensor and intake air temperature sensor. To make starting easier, the ignition timing is relatively retarded during engine cranking. As the engine starts, the timing is advanced quickly and then retards as the engine approaches idle speed. If the idle speed drops e. g. when switching on electrical equipment or the air conditioner , the timing is...
