Job:
Removing the Piping - Fig. 1 -
Stop engine. Release bolt (7), unscrew bolts (12) and
take down clip (10). Slacken union screw (1) through
one or two turns, so the inner seal will not be dama-
ged. Unscrew union nuts (2) (with dog wrench and
tommy bar) and (3) (with open-end wrench), and
remove pipe (4).
Measure inside diameter of injection piping. If it is
less than 3.0 mm, the injection piping must be recon-
ditioned (see Job Card 07.03.03).
Refitting the Piping - Fig. 1 -
Before mounting the injection piping, check
the clamping sleeves (14) - Fig. 2 - for firm
seating by means of socket wrench (5) (left-
hand thread!).
nspect pipe and fittings for cleanliness. Attach pipe
to connectors and screw union nuts (2) and then (3)
by hand in place until pipe ends are seated, at least
through five turns.
Should it prove impossible to screw union nut (2) in
place by hand, release injector. If this does not help,
trace cause and eliminate. If necessary, realign pipe
in cold condition or renew.
Now tighten union nut (3) as per Section 3.5, item 31.
Bleed pipe (see Job Card 07.03.02). Likewise, tigh-
ten nut (2). Slightly tighten union screw (1) and rese-
cure injector, where applicable (Job Card 07.07.01).
Now fasten pipe with bolt (12), lockwasher (13), plate
(11) and clip (10) to retaining plate (6). Secure retai-
ning plate by means of bolt (7), lockwasher (8) and
washer (9).
Be sure pipe is free of stress. If necessary,
place shims at point I or remachine clip at
point II.
