25. The efficient  operation of the injection  nozzle 
assembly  is dependent 
on four  main  conditions, as 
follows: 
The  nozzle  valve  must open  at 
135 Ats. 
The  rate of back  leakage  must  be within 
150 to 
100 Ats. 
Seat  tightness  must be sufficient  to prevent 
leakage. 
Spray  form 
must compare  favourably  with the 
illustrations. 
26.  Pressure  setting, back leakage  and seat  tightness 
tests  may be made  by coupling  the injection  nozzle 
and  holder  assembly...

3. Lightly grease the copper  washer into position on 
each  injector  before fitting to the  cylinder  head. 
4. Fit the  injector  and evenly  tighten  the retaining 
nuts 
to the correct torque 6 to 8 Nm (4 to 6 Ibs  ft). 
Uneven 
or overtightening of the injector nuts  could 
distort  the nozzle  and cause  misfiring when  normal 
running  temperature  is reached. 
5. Reconnect  the injector  pipes  but  do not 
overtighten
