Pressure-Measurement
Oil Pressure after Oil Filter before Bearing Road
Attention:
a. Engine must be turned
“off” before working with
the manometer.
b. While measuring the oil
pressure, engine must be
in hot (working) conditions.
1) Remove HOLLOW SCREW
M12x1,5 (SW 17)
2) Place M12x1,5 Hollow ScrewAdapter with Copper Seal Rings.
Adapter is marked with
number 88.
3) Tighten it with a torque of
20Nm+/- 2
4) Connect pressure kit hose and
use the 9 Bar- Manometer
Oil Pressure can be 1 – 7 Bar
depending on engine behaviour.
The max. allowed delta of oil pressure
measured after the oil filter and after the
bearing road (oil pressure sensor) should
not be more than 1,3 bar.

4) A correct functioning Fuel System
should have a min. pressure of
3.5 Bar.
If the measured fuel pressure is
too high  indicator for a blocked
fuel filter
It depends on the Fuel
specification and Fuel
Temperature.
