Porsche Synchronization Components A

The hub (A) connects the sleeve and pinion shaft. The shift sleeve (B) can move in an axial direction. The shift sleeve engages the 39 teeth of the hub with a loose fit. The champhered side (arrow) is used to hold the gear in the engaged position. The flat surfaces of the hub are machined the synchronizer ring and locking parts are held in place by these surfaces. The shift sleeve (B) of the Porsche synchronization system is the immediate friction part for the synchronizer ring. The teeth of...

Ignition System

The Porsche 928 models are equipped with breakerless transistor ignition. The control unit is located on the right front of the engine compartment. The ignition coil with both resistors is mounted on the left front of the engine compartment. There are timing marks at 5 intervals on the vibration damper. The TDC mark and the 31 BTDC ignition timing mark are colored to facilitate identification. The control unit receives current when the ignition 2 is turned on. When starting the engine, starter...

Info

19 Piston in slave cylinder The clutch and service brakes are operated by suspended pedals, which are mounted on a common shaft. By mounting plates on the pedals, the distance to the pedals can be reduced by 15 to 30 mm. The clutch pedal 1 rides on the shaft with two needle bearings to keep the operating force as low as possible. An over-center spring reduces pedal effort from approx. 21 kp to 14 kp. In the released position, the spring's force will be slightly in the direction of the pedal...

Transmission Electronic Speedometer Sending Unit

Speed related pulses are used to indicate the road speed and the distance travelled. A magnet carrier 7 with 8 permanent magnets 6 is located on the differential 14 . A sending unit 3 with a reed switch 4 is inserted in the rear transmission case cover 5 . Each magnet lt 6 passing the sending unit will close the reed switch 4 with its magnetic field. This magnetic field is not weakened by the aluminum transmission case or the plastic housing of the sending unit. As the differential 14 turns,...

Synchronizer ring

The synchronizer ring is the main part of the Porsche synchronization. The ring is slotted and has a slightly oval shape when relaxed. This oval shape approx. 1 mm provides an exact fit to the shift sleeve during synchronization. The inside surface with annular grooves is matched with the locking parts. The stressed outside surface has a molybdenum coat, which is only approximately 0.1 5 mm thick and very wear resistant. The frictional pairing of hardened steel against molybdenum assures...
