Crank Angle Sensor Unit
1. General
The crank angle sensor unit is installed at the free end. The connecting unit (2) is
attached to the crankshaft (10) over the driving shaft (1). The connecting unit absorbs
all unwanted radial and axial movements of the crankshaft.
The toothed belt (8) operates the two crank angle sensors (7), which give indications
of the crank angle positions. A proximity sensor monitors the position of the TDC
signal (see 4628−1 Pick-up for Speed Measurement).
All differences are monitored and displayed with an alarm.
You must lubricate the ball bearing (9) at regular intervals. For data about the
lubrication, see the Maintenance Manual 0380−1 and 9223−1.
