Removal and installation of the case of the gas-distributing mechanism (engines of 1.7 l of DOHC)

Removal

 PERFORMANCE ORDER

  1. Remove a camshaft cogwheel (see. Removal and installation of a natyazhitel of a belt and cogwheels of a drive of GRM (engines of 1.7 l). Uncover the gas-distributing mechanism (see. Removal and installation of a cover of the gas-distributing mechanism). Turn out two bolts of fastening of a back cover of a gas-distributing belt to the case of the gas-distributing mechanism.
  1. Remove fuel nozzles (see. Head of the Power supply system and release).
  1. Turn out bolts of fastening of an air sleeve of a turbokompressor and remove an arm from the left back part of the case of the gas-distributing mechanism and the inlet pipeline. Release clamps and separate a sleeve from an inlet air line.
  1. Turn out bolts of fastening of a tube of system of a retsirkulyatsiya of the fulfilled gases (EGR) to a final collector — do not forget about sealing laying.
  1. Release the big shtutserny socket, disconnect a tube from the EGR valve and remove it from the engine. Now it is possible to make removal from the case of the gas-distributing mechanism of the left back elevating eye of the power unit.
  1. Disconnect from a tube a hose of return of fuel. Disunite sockets of electroconducting of a heater.
  1. Liberate refrigerator lines of central air of air from clamps on the right mudguard. Disconnect electroconducting and turn out three bolts of fastening of the compressor of the conditioner to basic an arm. Separate the compressor from the engine and tie up it aside to the front panel.
  1. Turn out three fixing bolts and remove a basic arm of the compressor.
  1. Operating in strictly certain sequence, gradually, on a half of turn for an approach, weaken bolts of fastening of the case of the gas-distributing mechanism.
  1. Turn out fixing bolts and remove the case of the gas-distributing mechanism and its sealing laying.

Installation

 PERFORMANCE ORDER

  1. Make sure of absoluteness of purity and dryness of interfaced surfaces of the case and a head of cylinders — from surfaces all smallest traces of a material of old laying should be removed.
  1. Before installation of the case of the gas-distributing mechanism make sure of correctness of combination of labels of gear wheels of camshafts.
  1. Lay new laying on an interfaced surface of a head of cylinders. Press to a head the case of the gas-distributing mechanism, screw fixing bolts and, operating in strictly certain order, in stages evenly tighten them with demanded effort.
  1. Further installation is made an order, the return to an order of dismantle of components. Pay attention to the next moments:

    1. Check klapanny gaps, in case of need make the corresponding adjustment (see. Check and adjustment of gaps of valves (engines of 1.7 l of DOHC).
    2. Adjust tension of a belt of a drive of GRM (see. Removal and installation of a belt of a drive of GRM).
    3. Check connection of a hose and a tube of return of fuel on existence of signs of development of leaks.
