  3. Lift the receiver case ventilation between an inlet tube of a turbokompressor and a head of cylinders, and also a hose from an oil separator. Take a tube aside.
  4. Remove an inlet tube of a turbokompressor and take her aside (42 on an illustration).
  5. Disconnect a final hose of a turbokompressor to an interkuler (43 on an illustration).
  1. Disconnect a water hose (44 on an illustration) from the thermostat case.
  1. Disconnect a forward final collector from a turbokompressor (45 on an illustration).
  2. Remove cooling tubes (46 on an illustration) and supply of oil (47) from a turbokompressor.
  1. Give fixture and remove a camshaft of inlet valves (48 on an illustration). Give bolts on a half of turn for an approach. Pay attention to labels on covers of bearings. The last should uncover the bearing, near to the loaded pushers of valves. Remove epiploons.

Give bolts of fastening of a back head to sequences, return specified illustrations. It is not required to remove a camshaft of inlet valves.

  1. Take pushers of valves and arrange them so that then to establish on former places.
  2. Give bolts of fastening of a head of cylinders. At first give bolts on a turn quarter, and then on a half of turn. Remove a head of cylinders, trying not to bend valves.

Installation

 PERFORMANCE ORDER

  1. Make control measurements of a head of cylinders and compare them to requirements of Specifications.
  2. Make sure that the camshaft is in situation 60 a hail. to VMT.
  3. Clear interfaced surfaces of the remains of sealing materials and lay on the block of cylinders new laying by "OBEN/TOP" inscription up.
  4. Establish pushers of valves on their former places.
  5. Establish into place a head of cylinders and tighten it new bolts with demanded efforts and in the sequence specified an illustrations below.

Bolts of fastening of a forward head of cylinders tighten in sequence, return specified illustrations.

  1. Grease with a thin layer of impellent oil a final camshaft and lay it in a head of cylinders.
  1. Soriyentiruyte of a label on camshafts according to an illustration (A – a forward head of cylinders; B–back).
  1. Establish covers of bearings of camshafts, paying attention to the labels put on covers and on a head of cylinders. Put on a surface of a head of the cylinders, interfaced to covers of forward bearings of camshafts (C on illustrations) a thin layer of hermetic (No. 74 96 268 according to the Saab catalog). Tighten bolts of fastening of covers of bearings with effort of 8 N • m.
  1. Establish a back cover of a belt of a drive of GRM and cogwheels of camshafts according to the labels put on wheels and on a cover.

Number on a cogwheel should coincide with number on a shaft. Tighten bolts of fastening of cogwheels with demanded efforts.

  1. Make sure that pure dry sealing rings of a cover of a head of cylinders are laid by it on the places and establish a cover of a head of cylinders.
  2. Establish the ignition module.
  3. At installation of a forward head of cylinders establish the components listed on illustrations, in sequence, return to an order of dismantle of components.
Removal of hoses of a turbokompressor.
Removal of the SAI components and turbokompressor hoses.
  1. At installation of a back head of cylinders establish the SAI components and connect forward section of an exhaust pipe to a back final collector.
  1. Establish the water pump and assembly of tension and adjusting rollers.
  2. Establish fixing adaptations on cogwheels of camshafts.
  1. Turn a cranked shaft almost to a label «0» and establish on it the special adaptation. Then turn a cranked shaft till the moment when the lever the adaptation will rest against a flange of the water pump and remove the adaptation.
  1. Lay on cogwheels a belt of a drive of GRM according to the labels made at removal. Establish the bottom tension roller, but yet do not tighten its fixture. Make sure that the washer is on a place. Adjust a hand the provision of a roller (counter-clockwise) so that the belt did not move. Make sure that labels on a driving belt and on cogwheels of camshafts and a cranked shaft coincide.
  2. Establish on a belt of a drive of GRM a tension measuring instrument. Slightly tighten the central bolts of fastening of adjusting rollers. Turn the bottom adjusting roller so to receive a belt tension from 275 to 300 N • m then tighten a bolt of fastening of a roller. Again check a tension of a driving belt if necessary again adjust it.

Adjustment of a tension of a driving belt at this stage is preparatory procedure and its result cannot be used as check at a final tension of a belt.

  1. Clean fixing adaptations from cogwheels of 1 and 2 camshafts. Establish the special adaptation and turn the top adjusting roller counter-clockwise so that labels on cogwheels of camshafts coincided with the corresponding labels on the special adaptation. Tighten a nut of fastening of the top adjusting roller.
  2. Remove all special adaptations.
  3. Turn the engine on two complete revolutions that the cranked shaft slightly did not reach a label «0». Establish on a camshaft the special adaptation and turn a shaft till the moment when the lever of the adaptation will rest against a flange of the water pump. Remove the adaptation, establish a control template of situation VMT and make sure that labels on it are located opposite to labels on cogwheels of camshafts. Make sure that the belt of a drive of GRM lies aflush with cogwheels, and the label And is approximately on 2 mm above B label. If the last condition is not executed, adjustment of phases GRM should be made at first.
  4. Establish a splitter of system of cooling, and then and all other acting in film components in sequence, return to an order of dismantle of components. Tighten fixture with demanded efforts.
