Inspecting the Nozzle
Introduce needle (16) (Fig. 2) with diesel fuel into
nozzle element (15). When pulled out halfway by its
thrust pin, the needle must sink back onto its seat by
its own weight. Should the needle (16) bind, it must
be renewed as a unit with nozzle element (15).
Nozzles may not be reworked.
Since the nozzles are supplied in greased
condition, clean them in diesel fuel before
fitment.
Refitting the Nozzle
Clamp housing (4) (Fig. 1) in a vice with flat face at
top. If dowel pin (6) presents shear marks, renew pin.
Place nozzle element (15) with needle (16) and stop
bush (5) on the carefully cleaned and dried flat sur-
face. Apply Deutz S2 compound to thread of nut (7)
and pressure face between nozzle element (15) and
nut (7).
Tighten nozzle nut (7) as specified (Section 3.6,
item 50).
Do not tighten the nozzle nut beyond the value
specified, otherwise difficulties may be en-
countered when releasing at a future date.
Set injector with testing outfit (Job Card 07.08.01),
and check setting. To prevent baking on in the cylin-
der head, equip injector with new washer (29) and
apply heat-resistant Deutz S1 to nozzle element (15)
and to seat of injector. Install injector (Job Card
07.07.01).
Dismantling the Injector as a Whole
Unscrew clamping nut (18), separate adapter 19
from housing (4). Remove gasket (17). Screw out
sleeve (11) and adjusting screw (10). Turn housing (4)
upside down to take out spring (9) and plunger (8).
Remove nozzle as already described. Clean all com-
ponents. Renew O-seals (2) and gasket (17).
Reassembling the Injector as a Whole
Introduce plunger (8) and spring (9) into cleaned
housing (4). Turn in adjusting screw (10) and sleeve
(11) through a few threads. For further reassembly
and setting of injector, see ”Refitting the Nozzle”.
