BMW 5 Series: Direct rail
Mounting the injectors
- Mounting bolts
- Plastic sleeve
- Holding clamp with bayonet fitting
- Rail
- Solenoid valve injector
- Cast lug
The solenoid valve injectors are fastened to the holding clamp with a bayonet
fitting. There is a plastic
sleeve between the holding clamp and direct rail. This is not designed to
collect escaping fuel. This
is only used to support a helium leakage test during pre-assembly at the factory
in order to check the
tightness. After the initial assembly, this plastic sleeve is of no relevance to
the engine operation. When
the solenoid valve injectors are reinstalled or replaced, the plastic sleeves
are no longer required and
do not need to be reinserted.
The mounting bolts of the holding clamp must be replaced each time they are
released.
The housing on the solenoid valve injectors is sensitive to excessive
tensile forces and excessive
rotational angles. When removing and installing the solenoid valve injectors,
the procedure in the
current repair instructions must be followed If the solenoid valve injectors are
damaged, fuel may be
discharged.
