5.2 Assembling
Note the following points when assembling the injection valve:
⇒ Clean the injection valve parts. Use only clean diesel oil (gas oil) or fresh
kerosene, and dry compressed air.
⇒ The fitting position of nozzle tip 8, nozzle body 14 and nozzle holder 5 is given
by dowel pins 16 and 17 (Fig. ’D’).
⇒ Make sure that the red marked sealing faces ’SF’ are in perfect condition and
that no lubricant is applied.
⇒ Fit the nozzle tip in accordance with section 7.
⇒ If tappet 10, compression spring 12 and spring tensioner 7 with collar nut 6 are
already fitted, the spring tensioner must be screwed by approx. one turn only,
in order to prevent the compression spring from being under tension in any
case, otherwise nozzle body 14 does not lie flat on nozzle holder 5 during
assembly.
⇒ Apply a layer of Never-Seez NSBT-8 to the thread and the seating surface
’SS’ of coupling nut 11.
First tighten the coupling nut to 89
Nm (see paragraph 5.1) using socket
wrench insert 94269C−55 and torque spanner 94011A. Starting from this
position, tighten the coupling nut by a final angle of 30_ by means of test bench
94271 and hydraulic cylinder 94269B.
D Repeat the tightening procedure on the initial assembly.
D An angle of 30_ corresponds to 16.8 mm on the circumference relating to a nut
diameter of 64 mm.
⇒ Apply a layer of Never-Seez NSBT-8 to the thread and the seating surface
’SS’ of clamping nut 15.
⇒ Tighten the clamping nut to 172 Nm (see paragraph 5.1) using socket wrench
insert 94269C−41 and torque spanner 94011A.
After assembling the injection valve must be checked and judged according to
sections 2 and 3.
