Once the needle roller bearings (9) have been removed from the rocker arm (18), upon reassembly fit a new needle roller bearing (9) on drift part no. 88713.1071 And lubricate with recommended grease.
Support the rocker arm and drive the needle roller bearings into the rocker arm bore until the tool seats against rocker arm.
Important
Introduce the needle roller bearings aligned with the hole to avoid any sticking: use a press, if necessary.

Insert one new seal (8) (with the metallic side faced outwards) into the drift and bring it fully home on the previously mounted roller bearing.
Repeat the above procedure for the other roller bearing (9) and the other seal (8).
Insert the inner spacer (13).

Position the linkages (10) and (12) on the rocker arm (18) by starting the screw (14).
Apply grease to the threaded side of the screw (14) and to the contact face of the nut (21).
Start the nut (21) on the screw (14).
Tighten the nut (21) to a torque of 45 nm +/- 5% (sect. 3 - 3, Frame torque settings).


Apply grease to the thread and under the head of the screw (15) that secures the upper part of the shock absorber (11) and insert it in the rocker arm. Tighten the screw (15) to a torque of 45 nm +/- 5% (sect. 3 - 3, Frame torque settings).

If the shock absorber reservoir covers have been removed, apply lubricant specific for rubber on the inner surface of the rubber cover (26). Fit the cover (26) on the shock absorber reservoir (a) and engage tab (b).
Note
Rotate the cover (26) until face (c) nearly contacts the fitting (d).

Apply recommended lubricant on the internal surface of the reservoir (25) support.
Position support (25) on the cover (26) and rotate support until face (e) nearly contacts the fitting (d).
Fix cover (26) and support (25) using ties (28), and position the ties so that the external profile of the retainers is about 20 cm away from the edge of support (25).
Note
The top tie (28) (yellow arrow) needs to be fully open in order to be positioned in its seat.
Fit

Fit the plate (23) on the preload adjusting knob (34) starting the screws (22) with the recommended threadlocker.
Tighten the screws.

Introduction
The injectors used on the diavel are top feed units, meaning that fuel is fed
into the top of the injector itself. The
injectors contain a winding which raises a needle when electrically energised.
This opens the atomiser nozzle, through
which pressurised fuel is dispensed, gener ...
Removal of the starter motor idler gear
Slide the gear pin (21) complete with the gear (19) and washer (20).
