Back cover

 PERFORMANCE ORDER

  1. Remove a belt of a drive of GRM (see. Removal and installation of a belt of a drive of GRM).
  2. Remove camshaft and TNVD cogwheels, an intermediate roller and assembly of a natyazhitel (see. Removal and installation of a natyazhitel of a belt and cogwheels of a drive of GRM (engines of 1.7 l).
  1. Mark the adjusting provision of the right support of a suspension bracket of the power unit, then turn out three bolts of its fastening.
  1. Turn out six fixing bolts and remove a back cover from the engine.

Engines of 1.7 l of DOHC

Top section

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Remove an air purifier assembled with air lines (see. Head of the Power supply system and release).
  3. Prop up the engine a telezhechny jack — for the purpose of distribution of loading lay between a head of a jack and the case pallet wooden whetstone.
  4. Mark adjusting components of the right support of a suspension bracket of the power unit. Turn out three bolts of fastening of a support.
  1. Turn out fixing bolts and separate a support arm from an adapter on the engine block.
  1. In case of need disconnect electroconducting from the generator (see. Head engine Electric equipment).
  1. Turn out a fixing bolt with a TORX type head. Release clamps of fastening of a route trench of electroconducting and remove the last from the right back part of a head of cylinders.
  1. Liberate hoses from clamps on the top cover, turn out eight raznodlinny fixing bolts and remove the top section of a cover.

Bottom section

 PERFORMANCE ORDER

  1. Remove a belt of a drive of auxiliary units (see. Head Routine maintenance) — previously mark with paint or a marker the direction of its rotation. Cock the parking brake, поддомкратьте a front of the car and establish it on props. Remove the right forward wheel and (at the corresponding complete set) protection of a case.
  2. Remove the top section of a cover (see above).
  3. Remove a pulley of a cranked shaft (see. Removal and installation of a pulley of a cranked shaft).
  1. Turn out three fixing bolts and remove the bottom section of a cover from the case of the oil pump.
  1. Remove an adapter of fastening of a support of a suspension bracket the saga.
  1. Temporarily screw on the regular place a bolt of fastening of an arm of a natyazhitel of a gas-distributing belt.

Back cover

 PERFORMANCE ORDER

  1. Remove a belt of a drive of GRM (see. Removal and installation of a belt of a drive of GRM).
  2. Remove directing roller and a roller of a natyazhitel, camshaft and TNVD cogwheels (see. Removal and installation of a natyazhitel of a belt and cogwheels of a drive of GRM (engines of 1.7 l).
  3. Disconnect a spring of a natyazhitel.
  1. Turn out four bolts of fastening and remove a back cover of a GRM belt.

Engines of 2.0 l

 PERFORMANCE ORDER

  1. Remove the top chain and asterisks (see. Removal and installations of chains and asterisks of a drive of GRM, check of a condition of components (engines of 2.0 l).
  2. Remove a head of cylinders (see. Removal and installation of a head of cylinders).

Theoretically the cover can be removed without preliminary dismantle of a head, however such way is interfaced to risk of damage of sealing laying of a head of cylinders.

  1. Remove the water pump (see. The head of System of cooling, heating) — before a bolt otpuskaniye temporarily remove blocking core not to break it (do not forget to establish a core into place after the bolt will be weakened)
  2. Remove the case pallet (see. Removal and installation of the pallet of a case).
  3. Remove the generator (see. Head engine Electric equipment).
  4. Turn out a cap of the bottom natyazhitel from a back part of a cover and remove a plunzher of a natyazhitel — try to remember the adjusting provision of components. Remove from a cap a sealing ring — at installation the sealing ring is subject to replacement without fail.
  1. Turn out bolts of fastening of a cover of a drive of GRM to the block of cylinders — bolts have various length and at installation should be rolled strictly on the former places.
  1. Accurately separate a cover from the block and remove it from the engine — try not to lose directing plugs. If directing plugs have weak landing, remove them and combine in a reliable place.
  1. Turn out an axial bolt and remove from the block of cylinders boots of natyazhitel of the top and bottom chains.
  1. Turn out fixing bolts and remove from blokirator an uspokoitel of the bottom chain — try to remember the adjusting provision of components.
  1. Temporarily remove an asterisk of the bottom gas-distributing chain from a flange of TNVD and remove laying of a cover of a drive of GRM from the block of cylinders. Having removed laying, establish an asterisk on the place on a pump flange.

Installation

Engines of 1.7 l of SOHC and DOHC

Installation is made as it should be, the return to an order of dismantle of components.

Engines of 2.0 l

Before cover installation originators of the real Management recommend to replace epiploons of a cranked shaft (see. Replacement of epiploons of a cranked shaft).

 PERFORMANCE ORDER

  1. Make sure of absoluteness of purity and dryness of interfaced surfaces of a cover and the engine block. Check existence on the places of directing plugs — in case of need establish plugs.
  2. Temporarily remove an asterisk from a flange of TNVD and establish into place sealing laying, having tracked correctness of landing it on directing plugs. Establish an asterisk back on TNVD flange.
  3. Establish on the block of cylinders an uspokoitel of the bottom chain, screw and tighten with demanded effort bolts of its fastening.

Uspokoitel it is necessary to establish the step party outside.

  1. Establish into place boots of natyazhitel, screw an axial bolt and tighten it with demanded effort.
  1. Establish into place a cover of a drive of GRM — achieve combination of a driving gear wheel of the oil pump with an asterisk of a cranked shaft, then push a cover into place, having tracked hit of directing plugs in the reciprocal.
  2. Screw bolts of fastening and in stages gradually tighten them with demanded effort.
  3. Plant a new sealing ring on a cap of the bottom natyazhitel. Fill a plunzher (the deaf end to a chain). Establish a cap on a cover of a chain and tighten it with demanded effort.

At installation of a new natyazhitel unblock it, completely, before click having drowned the central core of a cap — now the core of a natyazhitel should freely утапливаться and smoothly come back to a starting position.

  1. Establish a pulley of a cranked shaft (see. Removal and installation of a pulley of a cranked shaft).
  2. Establish a head of cylinders (see. Removal and installation of a head of cylinders).
  3. Establish the top chain and asterisks of a drive of GRM (see. Removal and installations of chains and asterisks of a drive of GRM, check of a condition of components (engines of 2.0 l).
  4. Establish the case pallet (see. Removal and installation of the pallet of a case).
  5. Establish the water pump and the generator (see. Heads of System of cooling, heating and engine Electric equipment).
  6. Establish a belt of a drive of auxiliary units (see. Head Routine maintenance).
  7. In end, fill in in the engine oil and cooling liquid (see. Heads Routine maintenance and Systems of cooling, heating). Start the engine and make sure of lack of signs of development of leaks.
