ENGINE
CHECKING AND SETTING THE VALVE TIMING
Engine: RHR
Refitting.
Rotate the crankshaft ten times
(in the direction of rotation of the engine).
Peg the crankshaft, using tool [2] and the camshaft drive pinion, using tool [3].
Lock the flywheel, using tool [6].
Slacken the screw (8)of the auxiliaries drive pulley (7) and the screw (12)of
the tensioner roller (17).
Turn the tensioner roller
(clockwise), using a hexagonal spanner at «e».
Position the index «d»opposite the notch «f».
Tighten:
- The screw (12)of the tensioner roller (17)to 2,1 ± 0,2 m.daN.
- The auxiliaries drive pulley to 7 ± 0,7 m.daN.
Remove tools [2], [3]and [6].
Rotate the crankshaft two times
(in the direction of rotation of the engine).
Refit tools [2]and [3].
Check the position of the index «d», it should be opposite the notch «f».

CHECKS: LOW PRESSURE FUEL SUPPLY CIRCUIT
Tools.
[1] Ø 10 mm low pressure connector: 4215-T
[2] Ø 8 mmlow pressure connector: 4218-T
[3]Pressure gauge for testing boost pressure: 4073-T Kit 4073-T
Connect the tool [1]between the booster pump and the fuel filter
(white mark at "a" on the fuel
supply pipe).
Connect the tool [2]downstream of the diesel injectors, between the high pressure fuel pump and
the fuel filter
(green mark at "b" on the fuel return pipe).
WARNING: Any check of pressure downstream of the fuel filter is PROHIBITED.
Checks on pressure: static.
- Switch on ignition.
For 3 seconds
(normal functioning):
- Fuel supply pressure shown by the pressure gauge [3] = 1.8 ± 0.4 bar.
- Fuel return pressure shown by the pressure gauge [3] = 0.5 ± 0.4 bar.

CHECKS: LOW PRESSURE FUEL SUPPLY CIRCUIT
Checks on pressure: dynamic.
Engine running, at idle (normal functioning):
- Fuel supply pressure shown by the pressure gauge [3] = 2 ± 0.4 bar.
- Fuel return pressure shown by the pressure gauge [3] = 0.7 ± 0.4 bar.
Abnormal functioning
Fuel supply pressure Fuel return pressure Checks
Between 3and 3.5bar0.7 ± 0.2 bar Check the condition of the diesel filter
More than 3.5bar Less than 0.7barCheck the low pressure regulator incorporated
in the filter
(locked shut): replace.
More than 3.5bar More than 0.7barCheck the fuel return circuit
(pipe pinched or trapped…)
Between 0.8and 1.5bar Less than 0.7barCheck the fuel supply circuit:
- Booster pump (low pressure), piping
Impossible to start the engine:Check: diesel injector return flow
(table below).Fuel supply pressure less than 0.8 bar:
- Check the low pressure regulator incorporated in the filter (locked open).- Check the high pressure pump distribution valve (locked shut).Uncouple the diesel injector return pipe.
Check: Observe:
The flow should be drop by drop Diesel injector functioning correctly
Excessive fuel return Diesel injector locked shutEngines: RHY - RHZ (continued)
