5 Fit the pump head piece
into place and tighten the
screws (52), Fig 16-1 by hand. Fit and tighten the screws (9) by
hand.
Note! The sealing surfaces must be absolutely clean.
6 Tighten the screws (9) and (52) crosswise to torque in
three steps according to chapter 07., section 07.1 to ensure
equal tightening of every screw.
7 Turn the pump and fit the control sleeve. Move the fuel
rack to a position where two marks can be seen. One of the
control sleeve teeth is chamfered and this tooth must slide into
the tooth space between the marks of the rack.
8 Reinstall the upper spring disc (16) and spring (17).
9 Assemble the element plunger with the spring disc and
pressure plate (28).
Note the mark on one side of the plunger vane. The marked
side of the plunger vane must slide into the fuel rack side of
the control sleeve, i.e. correspond to the marks on the fuel rack
and the chamfered tooth of the control sleeve.
10 Reinstall the tappet assembly. The guiding groove of
the tappet must correspond to the fixing screw (21).
11 Screw in and tighten the fixing screw (21).
12 Check that the fuel rack can be easily moved.
13 Unless the pump is immediately mounted on the engine
it must be well oiled and protected by a plastic cover or similar.
The fuel ports and injection line connection must always be
protected by plugs or tape.
16.4 Injection line
The injection line consists of two parts, the high pressure connec-
tion piece which is screwed into the nozzle holder, and the
injection pipe.
The high pressure connection piece seals with plain metallic
surfaces and these surfaces are to be checked before mounting.
Always tighten the connection piece to correct torque before
mounting the injection pipe; also in case only the injection pipe
has been removed, because there is a risk of the connection piece
coming loose when removing the pipe.
The injection pipes are delivered complete with connection nuts
