Installation of a fuel atomizer


The prevention

For reduction of risk of occurrence of a fire and травмирования the personnel it is necessary to replace at each dismantling of atomizers sealing round rings new.

To remove or disconnect

1. A negative wire of the storage battery.
2. To dump superfluous pressure in fuel system.
3. The distributive pipeline in gathering from a head of cylinders. Dismantle of the distributive pipeline can be made without a detachment of feeding and drain fuel pipelines.

To disassemble

1. To shift a collar of an atomizer and to deduce it from gearing with nest ledges, to dissolve with fingers a collar and to remove it. The collar is not subject to a reuse.
2. To take out from a nest an atomizer in gathering.
3. To remove about both atomizers sealing rings and to throw out them as rings are not subject to a reuse.

To collect

1. To grease new sealing a ring with engine oil and to establish them on the atomizer case.
2. To establish a new collar on the atomizer case. The collar should settle down to in parallel electric socket.
3. To insert atomizers in gathering into nests of the distributive pipeline so that collars and electric sockets were outside. To establish an atomizer coaxially with a nest, to enter a collar into gearing with ledges of a nest and then completely to move an atomizer into a nest against the stop.

To establish or attach

See corresponding operation in subsection 5.4.14.

To examine

To include ignition and, without starting the Engine, to check up tightness of connections of fuel pipelines.
