4.2.3 Sensor X (determination of the trav-
elled distance)
• Fitting to tractors without 4-wheel drive:
The number of magnets depends on the wheel size.
The travelled distance between 2 impulses of adjacent
magnets must not exceed 60 cm.
Calculation:
wheel circumference ÷ 60 cm = number of
magnets
e. g.:
256 cm ÷ 60 cm = 4,27 = min. 5
Magnete
• Fitting to four wheel tractor and MB-Trac:
The hose clamp with magnet is fitted to the drive
shaft.
• Fitting to Unimog (Unimog w.o. signal socket)
Apply universal grease to tachometer shaft with the
magnets and insert with the yoke downwards.
Screw on tachometer shaft to the free end of the
adapter.

A tachometer adapter is available for
Unimog. Dismantle tachometer shaft
from the gearbox and fit the provided
adapter.
The sensor should point towards the
magnet with a gap of 5 – 10 mm. It
should be fitted so that it cannot vi-
brate.
F
By using the provided V4A-steel bolts
fit the magnets in the wheel rim.
Evenly distribute the magnets around
the circumference.
Fit the sensor to the stub axle bearing
by using the provided carrier in such a
way that the end of the sensor points
towards the magnets. The gap should
be 5 – 10 mm.
