Subaru Legacy/Outback

1. Remove a V-shaped belt (Routine maintenance see the Head).
2. Remove a pulley of a cranked shaft (see Has undressed Removal and installation of a pulley of a cranked shaft).
3. Uncover drive belt ГРМ (see Has undressed Removal and installation of forward covers of drive ГРМ).
4. Remove assemblage of a belt of drive ГРМ (see Has undressed Removal and installation of a belt of drive ГРМ, check of a condition of components).
5. Remove a camshaft cogwheel (see Has undressed Removal, check of a condition and installation of cogwheels of camshafts).
6. Disconnect the inlet pipeline (see the Head of the Power supply system and release).
7. Turn out bolts of fastening of an arm of compressor K/V to a head of cylinders.
8. Remove assemblage коромысел (see Has undressed Removal, check of a condition and installation of elements of a drive of valves).
9. Remove a camshaft (see Has undressed Removal and installation of camshafts).

10. Operating in strictly certain order, turn out 6 bolts bolts of fastening of a head of cylinders.  Bolts (1) and (2) leave wrapped on three-four coils for the purpose of head fixing at last stage.

11. Обстучав a head on perimetre a hammer with soft brisk, separate it from the block of cylinders.
12. Definitively turn out the remained bolts and remove a head.
13. Remove a sealing lining of a head of cylinders.

Try not to scratch interfaced surfaces of a head and the block!

14. Operating in a similar manner, remove the right head of cylinders.

1. Carefully smooth out and wipe dry interfaced surfaces of a head and the block of cylinders. For removal of all traces of a material of an old lining and a deposit use a firm plastic or wooden scraper. Also clear the bottoms of pistons. Be extremely cautious, - surfaces are easy for damaging. Remember that the dirt should not get in маслотоки, water galleries, channels and carving apertures - закупорьте their stoppers or stick with an adhesive tape. For prevention of hit of a deposit in backlashes between pistons and cylinders, fill the last of dense greasing which on termination of clearing procedure will be easy for removing a rigid brush. On termination of cleaning wipe all surfaces pure dry rags.
2. Survey interfaced surfaces of a head and the block on presence of deep scratches, cracks and other damages. Small defects can be eliminated small шабером, in more serious cases the head should be pierced, or to replace.
3. Make sure of cleanliness and dryness of carving apertures, - just in case blow their compressed air (it is possible to take advantage of the bicycle pump). Presence at deaf apertures of traces of greasing can lead to block destruction at a tightening of bolts as a result of increase of hydraulic pressure.
4. By means of a steel ruler and probeа лезвийного type check up planeness of an interfaced surface of a head (see Has undressed Service of a head of cylinders of the present Chapter).

1. Having replaced a sealing lining, establish a head of cylinders on the regular place on the block.
2. With impellent oil grease carving parts of fixing bolts, persistent surfaces of their heads and a washer.

3. Screw bolts and tighten them in strictly certain order, with effort of 29 Nanometers, then, in the same order hold on with effort of the second stage (69 Nanometers).

4. In two steps release bolts, turning everyone on 180 ° for the approach.
5. Tighten bolts (1) and (2) with effort of 34 Nanometers, then tighten bolts (3), (4), (5) and (6) with effort of 15 Nanometers. Further hold on all bolts in ascending order serial numbers for 80 ч 90 (no more) than degrees.

6. At the final stage it is necessary to hold on bolts for 80 ч 90 degrees in an order specified in illustrations.  The total corner дотягивания at last two stages should not exceed bolts 180 °!

7. The further installation is made in an order, the return to an order of dismantle of components.
