Sweeney2255So the ref sensor to flywheel stud top is not 0.8mm? its o.5mm? Not sure what happened to the old one but was flush 😕
WaylanderFlywheel stud (for ref sensor) screw in with loctite 270 and adjust to 5+- 0.1mm that means 5mm + - 0.1 does it not, or am I reading that wrong
peanutCrank speed and hall effect sensors operate differently . The hall effect sensor registers when a magnetic field passes the sensor , it then emits a electrical signal in the form of voltage every time a magnetic field passes the sensor . The hall effect ( HE) sensor on the back of the distributor housing senses the position of the cam of each cylinder relative to TDC (half crank speed ) and sends a signal to the ECU which on the Motronic 2.5 tells the ECU which injector to pulse sequentially The crank TDC sensor on the bell housing is essentially a magnet which creates a magnetic field . When the flywheel reference pin passes the sensor it varies the magnetic field sending the position of TDC to the ECU .The gap from reference pin to sensor is critical. Later cars have a combined speed sensor and TDC position sensor and use a toothed ring attached to the flywheel.
