Dear Dealers,
Situation
Through ongoing analysis of customer concerns, we have identified reports of difficult
detection of the “neutral” gear (N) with consequent possible engine cranking. The clutch
installed on the Ducati models has been designed so that, both in cold engine (ambient
temperature) and warm engine conditions, the correct quantity of oil and pressure are ensured
for a proper lubrication of all mechanical parts for correct operation.
This Service Bulletin is to provide you with the correct procedure to measure and adjust the
clutch oil pressure if the situation mentioned above should occur or in case of crankcase
replacement. Note: this procedure applies only to the models with adjusting threaded dowel.
Beginning January 2018, the clutch oil pressure check is carried out in the production
department. All new units manufactured since that time should not require adjustment unless
necessary during other service or repair work.

NOTE
Due to different crankcase design on the Diavel and XDiavel models, it is necessary to
use the mounting base portion of tool part no. 887132695, remove the oil pressure
detection rod and fit rod part no.887136156 instead.

In conjunction with the tools specified above it is also necessary to use a pressure
measurement tool:
Analog oil pressure measurement
A. Precision glycerin-filled pressure gauge (2) with incremental measurement from 0-2 bar
B. Polyurethane Rilsan pipe (1) 40x60 mm and with a length of L=300mm
C. Two quick-release inserts (3) for Rilsan pipes to connect the pressure gauge and the
clutch pressure specific detection tool

Procedure to measure and adjust the clutch oil pressure
NOTE
Following example is the procedure to measure and adjust the clutch oil pressure of the
SuperSport model using the specific tool part no. 887132695. Proceed in the same
method for the other models using the specific tool required for the model.
WARNING
To take the clutch oil pressure measurement correctly it is necessary that the test is
performed with engine at ambient temperature (bike has not been running for approx. 12
hours).
1.
Position the bike on the rear paddock stand
2. Take clutch oil pressure measuring tool part no.887132695 (Please refer to chart for the
correct tool number applicable to the vehicle model being tested)
3.
Install measurement tool on pressure adapter tool
4.
Remove the 3 screws (4) M6x16 securing sprocket cover (5) and slide it out
5.
Remove the screw (6) M6x16 securing plug (7) (for models with cable actuated clutch)

NOTE
For the models with hydraulic clutch control rod it is necessary to remove the clutch
actuator unit (8) and the control rod (9)
6. Install clutch oil pressure measuring tool part no. 887132695 and secure gently with key (10)
NOTE
The special tool part no.887132695 is used in this example with the SuperSport model.
Please refer to chart for the correct tool number applicable to the vehicle model being
tested

WARNING
To correctly measure clutch oil pressure:
• The test must begin with engine at ambient temperature (bike has not been
running for approx. 12 hours)
• Engine rpm: 2500 rpm
• Pressure read and adjusted if needed within the first 30 seconds from engine
starting to avoid oil temperature to increase beyond 30°C
NOTE
We recommend performing this operation with the help of a second operator to
enable clutch oil pressure reading and adjustment, while a maintaining the
appropriate engine RPM
The following table shows the clutch oil pressure ranges for all models equipped with engine
with pressure adjusting threaded dowel:
