Removal

 PERFORMANCE ORDER

1. Remove the distributor (see. Head engine Electric equipment).
2. Uncover heads of cylinders (see. Removal and installation of a cover of a head of cylinders). Completely weaken adjusting screws of valves (see. Head Routine maintenance).
3. Bring the piston of the first cylinder into situation VMT (see. Reduction of the piston of the first cylinder in the provision of the top dead point (VMT)).
4. Remove a gas-distributing belt and cogwheels of camshafts (see. Removal, check of a condition and installation of a gas-distributing belt and cogwheels of a drive of GRM).
5. Check covers of bearings of shaft on marking existence in the form of the arrows specifying in the direction to a belt of a drive of GRM. In case of need put the corresponding labels independently by means of a chertilka. Also number covers (with the first on the sixth in the direction from a gas-distributing belt) and mark them on belonging to a concrete shaft (inlet or final).

The wrong installation of holders of shaft, and also rotation of the last not in that direction can lead to jamming of assemblies.


6. Moving from the center outside, in stages (on 1/4 turns for an approach) weaken bolts of fastening of covers, having brought to naught effort developed by klapanny springs.
7. Take camshafts from a head of cylinders, afterwards take yokes (mark landing position of the last – at assembly they should be established strictly on former places).

Check a condition of axes of yokes. Defective components replace. Do not forget to make sure of passableness маслотоков axes of yokes.
2. Estimate degree of wear of cams of camshafts:
   a) Check liftings of cams on existence of deep scratches, задиров, cavities and signs of non-uniform operation;
   b) In case of detection of defects replace a shaft, previously having found out and having eliminated a cause of wear. Check impellent oil on existence in it of an abrasive, make sure of passableness маслотоков. Wear of cams is connected with oil pollution more often;

   c) By means of a micrometer measure height of cams (see an accompanying illustration).

3. Check bearing necks and in bulk and a cover of bearings on existence задиров and signs of non-uniform wear. In case of detection of defects replace a head of cylinders.
4. Measure working gaps in bearings by means of the calibrated wire from Plastigauge set:
   a) Wipe covers of bearings and a neck of shaft the pure rags moistened in acetone;
   b) Accurately lay shaft in a head of cylinders (without any greasing).

In the course of procedure performance shaft should not be turned.


   c) Lay pieces of the calibrated plastic wire from Plastigauge set along bearing necks of a shaft (see an accompanying illustration);

   d) Establish to the place of a cover of bearings, then in stages tighten their fixture with demanded effort (move from the shaft center outside);
   e) Give bolts and remove covers;

   f) Measure width of the flattened-out pieces of the calibrated wire on a scale put on packing of a set (see an accompanying illustration);

   g) If results of measurements fall outside the limits an admissible range (see. Specifications), replace worn-out components;
   h) Edge of a credit or payphone card scratch out from shaft necks the remains of the flattened-out wire.

Installation

 PERFORMANCE ORDER

1. Grease all components with assembly greasing, or pure impellent oil, then establish to the place of assembly of yokes (watch landing marking).
2. Grease cams and necks of camshafts with special assembly greasing, then lay shaft in the bearings (do not mix an inlet shaft with final). Surfaces of covers of the 1st and 6th bearings interfaced to a head grease with anaerobny hermetic. Establish covers, then, moving from the center outside, in stages evenly tighten fixing bolts with demanded effort (see. Specifications).
3. Further installation is made as it should be, the return to an order of dismantle of components. In case of need make adjustment of klapanny gaps (see. Head Routine maintenance).
4. Start the engine on existence of signs of leaks and serviceability of functioning.
