Appendix L. Installing LLS 20230 Fuel Level Sensors 3 to 6 m in Length
Determine the necessary length of the fuel level sensor LLS 20230 and cut off the sensor extension part.
Attention! The sensor extension part should be cut off only from the side without a thread.
Place the fuel level sensor LLS 20230 and the sensor extension part as shown on the Figure (Figure 52). Measure 50 mm from the end of each part and make marks.
Put the nut, the ring, and the coupling on the fuel level sensor LLS 20230; put the nut and the ring on the sensor extension part (Figure 53).
Shift the nut, the ring, and the coupling according to the fuel level sensor LLS in a way to provide the obstacle free access to the thread of the extension part of the fuel level sensor LLS. Match and tighten the central pivots (Figure 54). A gap between the tubes should not exceed 10 mm.
Set the rings and the coupling according to the marks. Consecutively tighten the nuts by a nut wrench of the size 32, holding the coupling.
Make sure that there is no backlash or rotation between the tubes of the sensor.
Attention! It is prohibited to carry the fuel level sensor LLS, holding it by the sensor extension part (Figure 57).
