Precautions relating to maintenance (3)
Handling of the torque sensor
1. Keep away from magnets.
Do not use magnetized screwdrivers or per­
form maintenance near large sources of
electric power.
2. Avoid strong mechanical impact.
Torque sensors which have been dropped or
which have been removed through the use
of a hammer or the like cannot be used be­
cause the torque sensor reference volt age
can change significantly due to varia tions in
the internal magnetic circuits.
3. Do not crush or press in the axial direction.
Any deformation of the torque sensor case
by crushing can result in changes in the
torque sensor reference voltage. Torque
sensor reference voltage changes can also
be caused by the application of a force of
over 2 kgf on the sensor shaft while the case
is clamped in place.
The installation of a one­way clutch having a
tightly­fitted spline can apply excessive force
to the sensor shaft and result in volt age
changes.
4. Do not pull leads.
Do not pull forcefully on the small circuit
board leads which connect the torque sen­
sor body to the torque sensor. It can change
the torque sensor reference voltage.
5. Do not allow water to come in contact with
the Drive Unit.
Any rust on the sensor shaft or the main axle
can cause output fluctuations or can reduce
the strength of the parts. Do not per form ser­
vicing on the sensor in wet loca tions.
6. Organic solvents
Do not apply gasoline or solvent­based lubri­
cants (consumer spray­type lubricants) to
the sensor shaft or the circuit board. It can
reduce the unit’s ability to prevent short­cir­
cuits.
7. Do not reuse damaged drive axles.
The sensor shaft and the drive axle slide in a
metal bearing. It will be difficult to install the
one­way clutch and the sensor shaft if there
are scratches on the surface of the drive
axle.
8. Do not disassemble the torque sensor.
Do not disassemble the interior of the sen sor
because the torque sensor cannot be read­
justed. Torque sensors that have been disas­
sembled cannot be used.
