Gen3_ITC - Installation - Volvo L120H Main Head & Rod Pressure Sensors
The hydraulic pressure sensors are used to measure the lifting load of the ITC
Installation Steps:
- Completely lower the boom. Apply
the handbrake and insert chock
under wheels.
Once lowered, release any residual
pressure by pulling on the manual
release valve.
- The rod end pressure sensor is
installed inline with the rod hydraulic
line on the left hand main lift
cylinder. The sensor is installed
using the manifold block.
- Remove the existing the rod end line
from the connection point.
- Install the manifold block (HY001103) in series and apply the new longer bolts M12 x 70mm. Tighten the bolts for the hose to 41 Nm using a torque wrench. Make sure the sensor is positioned facing downwards on the right hand side.
- The Head End pressure sensor is
installed in the counter balance
valve block.
It is installed on the left hand main
lift cylinder.
- First remove both head and rod
fittings from the manifold block.
Install the pressure sensor at the
rear port marked TP.
- Reconnect the rod fitting and then
reconnect the hydraulic lines.
Start the machine, pressurise the
boom and check for leaks.
- Connect the supplied M12 4 metre
cables (CB001026) into each of the
pressure sensors.
Cable tie to the flexible hydraulic
hoses nearest to the sensors. Make
sure the cable isn't pinched or
stretched when the boom is raised
or lowered.

Failure to tighten the bolts to the correct torque on the
pressure manifold may result in a pressure failure on the
counterbalance valve causing an uncontrolled fall of the boom.
