3. Fitting
Fitting procedure is analogous to the removal but in reverse sequence. The fuel
pressure pipings must be installed as stress-free as possible achieving a proper
sealing function.
Before fitting HP fuel pipes 1, 2 check whether their claws 18 are screwed on pro-
perly, i.e. HP fuel pipe must protrude by ’x’ = 10 mm compared to the claw.
Measurement ’x’ can be adjusted by turning the claw using an open end spanner.
⇒ Replace O-rings 19 and 20 by new ones if necessary.
⇒ Apply Never-Seez NSBT-8 to threads and head surfaces of screws 8, 13, 15,
15a.
⇒ Place HP fuel pipe and slightly tighten screws 15 (13) on flange 14 (12).
⇒ Fit intermediate ring 10 (10a) onto upper flange 9 (14a) of HP fuel pipe 1 (2).
⇒
Carefully align bended pipe. If necessary, correct the alignment by rotating the
pipes around their vertical axis.
Remark: During alignment, take care not to damage sealing faces ’DF’. These
should be parallel to each other.
⇒
Tighten screws 8, 13, 15, 15a crosswise with a torque of 55 Nm .
Check the parallelism of all flanges 9, 12, 14, 14a by means of a feeler gauge.
D
Fasten clamps 6 as stress-free as possible and equally tighten their screws 7.
Retighten the clamps according to 0380 − 1 (see: Holder).
