4.4. Removal and engine installation

In order to avoid unapproved operation of pillows of safety start to work after not less than 10 minutes after switching-off of the storage battery.


Engine removal is made after preliminary branch from it transmission.

 PERFORMANCE ORDER

  1. Switch off ignition.
  2. Open a cowl.
  3. Disconnect a negative wire from the battery.
  4. Carefully mark all lines of communication subject to a detachment (electroconducting plaits, vacuum and air hoses, приводные cables, fuel lines and tubes охладительного a path).
  5. Dump pressure in the power supply system (Check компрессионного pressure in cylinders see).
  6. Remove a cowl.
  7. Empty system of cooling and remove a radiator (see the Head of System of cooling and heating).
  8. Remove belts of a drive of auxiliary units, the generator and assemblage of the fan of system of cooling (see the Head of System of cooling and heating).
  1. Remove the steering pump and compressor K/V, — without disconnecting hydraulic / refrigerator lines, shift components aside and fix their wire.
  1. Make a detachment of all disturbing to performance of procedure of lines of communication.
  2. Поддомкратьте the car also establish it on props (the Scheme of an institution of props for car fixing in the lifted position see an illustration). Remove protection картера.
  3. Disconnect from a final collector of the engine reception pipes of system of release of the fulfilled gases.
  4. Disconnect from transmission of a line of cooling ATF, приводные draughts and electroconducting. Take щуп measurements of level ATF.
  5. Mark position of a connecting flange карданного a shaft concerning the main transfer of the back bridge. Also mark heads of fixing bolts, — at assemblage they should be rolled strictly on the former places. Turn out fixing bolts and remove propeller a shaft. At once закупорьте an aperture under shaft installation in transmission in order to avoid hit in a dirt.
  6. Remove a starter.
  7. Turn out bolts of fastening of the hydrotransformer to приводному to a disk. Prop up transmission тележечным a jack and remove bearing beam laid under it. Disconnect from the engine block a basic arm of transmission.
  8. Will hang out the engine from above on лебедке.
  9. Turn out fixing bolts, cautiously separate transmission from the engine and take it from under the car (the line see Head Transmissionnaja).
  10. Give nuts of fastening of support of an engine mount to a frame (the Scheme of the organisation of a suspension bracket of the power unit see an illustration).
  11. Lift the engine and take it from the car.


Installation

Installation is made in an order, the return to an order of dismantle of components, — track, that all fixture has been tightened with demanded effort.

Having finished installation, make necessary adjustments приводных cables and levels of working liquids.
