This procedure prescribes that:
- The fuel pipelines (from pumping elements to
injectors, bleeding recovery pipes from injectors
to pump, LDA pipeline and feed provided by
priming pump) shall all be disassembled.
- Electrical connection to feed pump shall be
disconnected.
- Accelerator cable shall be disconnected.
Feed pump unit assembly and disassembly
procedure
In case feed pump replacement is necessary, this shall be
supplied pre−set already as spare part.
On the other hand, in case the pump shall be disassembled
and reassembled later on without being repaired it will be
necessary to pr−set it while it is still assembled to the engine
and disassemble it only afterwards.
The following procedure analyses this second hypothesis
since it is the more complex.
