SETTING THE BOSCH MECHANICAL INJECTION PUMP

XANTIA

Engine : DHX

TOOLS

- Flywheel locating peg

- Ring spanner

- Crescent spanner FACOM 57

- Dial gauge

- Dial gauge bracket

- 31 mm lever

: 7017-T.R.

: 4132-T.

: 11 X 13

: 3089-T.H.

: 7010.T.

Kit 7004-T

Kit 4123-T.

ꢀ

: 5003-T.D.

SETTING THE INJECTION PUMP

-Tilt the pump in the retarded direction (away from the engine).

- Fit the timing tool.

- Turn the engine (direction of engine rotation) until the peg engages in the flywheel.

- Ensure that the pump pinion can be pegged (if not, rotate the crankshaft by 1 turn).

- Remove the tool 7017-T.R.

- Find the B.D.C. position of the pump (by turning the crankshaft backwards) and set the dial

gauge to "0".

- Turn the crankshaft (direction of engine rotation) until locating peg 7017-T.R engages.

- Turn the pump, in the advance direction (towards the engine) until the dial gauge shows

(See the table on page : 158).

NOTE : The dial gauge needle must not move when tightening.

SETTING THE BOSCH MECHANICAL INJECTION PUMP

Engine : DHX (continued)

CHECKING THE INJECTION PUMP SETTING

- Remove the tool 7017-T.R.

- Rotate the crankshaft by 1/4 of a turn (opposite direction of rotation).

- Rotate the crankshaft (direction of rotation).

- Peg the flywheel.

- In this position, the dial gauge should show the value "X" (See the table on page : 158).

- The value "X" corresponds to the travel of the pump piston in relation to the B.D.C.

- Remove the tool.

ADJUSTING THE BOSCH MECHANICAL INJECTION PUMP CONTROLS

XANTIA

Engine : DHY

Engine cold.

- Check the fast idle speed.

- Ensure that the lever (3) is against its screw stop (1) by pushing it in the direction of the arrow # .

If not, adjust with the cable clamp (2), and then the cable tightener (6).

Engine hot.

- Ensure that the cable (9) is slack.

- Engine stopped : fully depress the accelerator pedal, check that the lever (8) is against its stop (7).

If not, move the position of the spring clip (B).

Adjusting the idle speed.

- Loosen the screw (5) until there is no longer any contact with the end of the screw.

- Move the screw (4) to obtain an engine speed of (see the table on page: 158).

Adjusting the residual output.

- Insert a shim "A" of (see the table on pages 158), between the lever (8) and the screw (5).

Adjust the screw (5) to obtain a speed of (see the table on page 158).

Adjusting the fast idle speed.

- Place the lever (3) against the screw (1) and turn the screw to obtain an engine speed of (see table

on page 158) .

- Check the operation of the manually-operated "STOP" control.

Adjusting the throttle lever switch (C).

- The contacts will open for an accelerator cable travel of 11 mm or a clearance of 8.5 mm at A".

FITTING BOSCH INJECTORS

Engines : RHY - RHZ

Evolution : Classification of diesel injector carriers

Reminder : RHY and RHZ are equipped with 4 diesel injector carriers marked according to their injec-

tion duct diameters (flow of diesel fuel).

16/11/98 #

Identification.

The injector carriers have an engraving or paint mark on the upper part of the coil, close to the diesel

fuel return aperture

Mark 1 = BLUE paint mark = Injector class 1.

Mark 2 = GREEN paint mark = Injector class 2.

Identification marking:

a : Supplier identification.

b : PSA identification no.

c : Identification of class.

After Sales operations.

ESSENTIAL : When changing a diesel injector carrier, order a component of the same class.

# 15/11/98 (RPO No.) (injector carrier without marking), always order a class 2 injector carrier.

FITTING BOSCH INJECTORS (continued)

Engine : THY

Fitting an injector.

[1] Injector spanner 77510-T

[2] 7008-T Kit 4123-T

The copper seal (1) and the fire seal washer (2) are to

be replaced each time they are removed.

NOTE : Fitting parts of different makes is PROHIBITED.

WARNING : Ensure that the fire seal washer (2) is

fitted the right way round

The needle lift type injector (4) is located on cylinder

No. 3.

WARNING : Should the needle lift sensor fail, the

injector holder assembly must be replaced.

IMPERATIVE: Do not reset the pressure of the injector

holder (4).

(3) Tighten lightly to avoid distortion.

Tighten to: 7 m.daN.

Tighten the injector holder on

the cylinder head to : 4.5 m.daN.
