Removal and installation of fuel atomizers

Observe extra care! Do not substitute under nozzles of atomizers of a hand and other parts of a body!


Do not suppose dirt hit in a power supply system path!


Remember that atomizers are among the precision equipment and to address with them follows extremely cautiously!

Models 1.7 of l SOHC

 PERFORMANCE ORDER

  1. Disconnect from atomizers of a line of return of fuel.
  1. Carefully wipe штуцерные connection sockets to atomizers топливопроводов, then release накидные nuts. At a detachment of tubes from the pump hold a reciprocal part of a socket with the second рожковым a key. Расстыковав sockets, remove fuel lines from the engine, at once collect the spilt fuel pure rags.
  1. Wipe surfaces round atomizers and remove the last from a head of cylinders.

Turn out not only the atomizer case, but also its basis, otherwise is great risk of loss of internal components, and assemblage will demand of some the adjustments which performance is obviously possible only in the conditions of a car-care centre workshop.

  1. Take from nests under landing of atomizers sealing (пламязащитные) washers, at washer assemblage are subject to replacement without fail. Try not to undertake attempts of dismantling of atomizers by own forces.
  2. Diagnostics of a condition of atomizers demands application of the special equipment and it is necessary to charge its performance to experts of car-care centre.
  1. Installation begin with placing in a head of cylinders sealing (пламязащитных) washers.
  1. Accurately screw atomizers and tighten them with demanded effort.
  2. In summary establish fuel lines and track, that штуцерные nuts have been tightened with demanded effort.

Models 1.7 of l DOHC

 PERFORMANCE ORDER

  1. Uncover газораспределительного the mechanism (the Engine see the Head).
  1. Turn out five fixing bolts and remove an internal line of return of fuel. Remove copper sealing washers. New copper sealing washers are established on both parties штуцерных sockets of connection of a line of return of fuel to atomizers.

Washers of sockets of connection of tubes to case GRM also are subject to replacement.

  1. Give fixing nuts and remove assembly collars of atomizers.
  1. Take atomizers from a head of cylinders, copper sealing washers is subject to replacement without fail. Will throw out rubber consolidations and copper washers. Try not to undertake attempts of dismantling of atomizers by own forces.
  2. Diagnostics of a condition of atomizers demands application of the special equipment and it is necessary to charge its performance to experts of car-care centre.
  1. Assemblage begin with clearing of interfaced surfaces of atomizers and a head of cylinders. Establish on each atomizer new rubber and copper sealing elements, - track correctness of placing of copper washers.
  1. Establish atomizers in a head of cylinders and fix their assembly collars. Tighten nuts of fastening of collars with demanded effort.
  2. Connect a line of return of fuel to the case газораспределительного the mechanism and to atomizers. Tube fastening to case GRM is carried out by means of a bolt большего diameter (do not forget to replace a copper sealing washer), with the top part of an atomizer and under each bolt new copper sealing washers should be established. Tighten bolts the ordered moments.
  3. Establish a case cover газораспределительного the mechanism (the Engine see the Head).
  4. Start the engine and check up it on presence of signs of development of leaks.

L models 2.0

Stripper KM-928-B is necessary for removal of a spray of an atomizer from a head of cylinders with оправкой adapter KM-931. At installation new bolts of a transitive tube be required.


 PERFORMANCE ORDER

  1. Remove the top section of an inlet collector (item 7 see above Model 1.7 of l DOHC,).
  2. Remove a camshaft and levers of a drive of valves (the Engine see the Head).
  3. Disconnect a returnable tube from a transitive tube of an atomizer.
  1. Turn out a fixing bolt, accurately separate a transitive tube from the top part of a spray of an atomizer and take it изголовки cylinders.
  1. Remove sealing rings from a transitive tube and the top part of a spray of an atomizer, - rings is subject to replacement without fail.
  1. Establish оправку and a stripper on the top part of a spray of an atomizer both in regular intervals and accurately remove a spray from the top part of a head of cylinders. Remove and will throw out the sealing rings established in the basis of a spray, - at ring assemblage is subject to replacement without fail.
  1. Plant on the bases of sprays new sealing rings, then accurately fill sprays in the top part of a head of cylinders, having tracked correctness of combination their directing pins with dredging on a head.


  1. Make sure of density of landing of a spray of an atomizer in a head of cylinders, plant on its top part a new sealing ring.
  1. Plant new sealing rings in ledges on transitive tubes. Establish transitive tubes on the regular places in a head of cylinders, - track correctness of their placing on the top part of sprays of atomizers. Screw new fixing bolts, tighten them against the stop manually.
  1. Then hold on a key on one complete revolution (360 ).
  1. Attach a returnable line to transitive tubes and establish the top part of the inlet pipeline (Removal and installation of the inlet pipeline see).
  2. Establish into place a camshaft and levers of a drive of valves (the Engine see the Head).
