Crankshaft Seal Flange with Integrated<br />
Engine Speed Sensor Wheel<br />
The crankshaft seal flange with integrated<br />
engine speed sensor wheel is a new<br />
feature. The crankshaft seal flange seals the<br />
cylinder block on the flywheel end. The seal<br />
is made of heat-resistant and nonwearing<br />
polytetrafluoroethylene (PTFE) plastic.<br />
The engine speed sensor is a Hall effect<br />
sensor mounted in the crankshaft seal<br />
housing and consists of a steel ring<br />
mounted in rubber. This rubber material<br />
contains embedded magnetized metal<br />
chips that have an alternate north and south<br />
polarity with a large north pole to serve as a<br />
reference for the engine speed sensor. The<br />
sensor wheel is precisely press-fit into the<br />
crankshaft flange.<br />
