Risk of Destruction!
The fastening screws of the knock sensors must not be tightened too much,
otherwise the sensors will be damaged and will no longer function properly.
Observe the following information for sensor mounting:
– Torque: 20 Nm ± 5 Nm (14.8 ± 3.7 lb-ft) for mounting screws:
–
made of cast iron: M8 x 25 mm (0.98"), Strength: 8.8
–
aluminium: M8 x 30 mm (1.18"), strength: 8.8
– Torque: 15 Nm ± 5 Nm (11 lb-ft ±2.2 lb-ft) for M6 fixing screws, strength
10.9 with sleeve .
The torque for mounting in the case of mounting with M8 screws (strength 8.8) is 20 Nm ±5 Nm
(14.8 lb-ft ±3.7 lb-ft) and with M6 screws (strength 12.9) with sleeve 15 Nm ±3 Nm (11 lb-ft ±
2,2 lb-ft).
Also, lay the sensor cables in such a way that no resonance vibrations can occur on the cable.
Otherwise, there is a risk of breakage.
The required mounting of the knocking sensors may vary depending on the engine type used.
The following locations are, in principle, possible for fitting the knocking sensors taking into
account the aforementioned specifications
– On the engine block
For mounting on the engine block use screws of the type M 8x30-8.8 (AL-engine block) or
M 8x25-8.8 (CI-engine block).
