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 new 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) on the
carefully cleaned and dried flat surface. 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 in cylinder head
(Job Card 07.07.01).
Dismantling the Injector as a Whole
Unscrew cap (12). Turn 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 components. Renew O-seals( 2)
and gasket (13).
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 installing the nozzle
and setting of injector, see ”Refitting the Nozzle”.
