Removal and installation of a head of cylinders

Start work performance only after full cooling of the engine!

Removal

PERFORMANCE ORDER

Disconnect and remove the storage battery (see the Head of System of an electric equipment of the engine). Empty cooling system (see the Head of System of cooling of the engine, salon and air conditioning heating). Turn out spark plugs and remove a belt of a drive of auxiliary units (see the Head of Adjustment and car routine maintenance). Remove a belt of drive ГРМ (see Has undressed Removal and installation of a belt of drive ГРМ). Components of assemblage of a head of cylinders 1 — the Cover of bed of a camshaft 2 — the Bolt, effort of a tightening: 8 Nanometers 3 — the Sealing lining 4 — a camshaft Epiploon. For removal turn a washer and flat-nose pliers take out a bolt together with a sealing ring. 5 — a camshaft Cogwheel 6 — the Washer 7 — the Bolt, effort of a tightening: 45 Nanometers; it is necessarily replaced 8 — Koromyslo 9 — the Hydraulic jack 10 — Press an element 11 — Crackers 12 — the Top plate of a spring 13 — the Spring 14 — Maslootrazhatelnyj a cap 15 — the Bottom plate of a spring The final valve: the rotary device of the valve The inlet valve: a spring saddle 16 — the Sealing lining of a head of cylinders 17 — the Valve 18 — the Head of cylinders 19 — the Bolt, effort of a tightening: 8 Nanometers 20 — the Restrictive plate 21 — the Camshaft 22 — the Washer 23 — the Bolt of fastening of a head of cylinders 24 — camshaft Bed Remove the inlet pipeline and a final collector (see the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases). If the head of cylinders is not subject to service, it can be removed in gathering with the pipeline and a collector: Mark with a tape and disconnect all electroconducting going to a head of cylinders, to the inlet pipeline and the case throttle заслонки; Dump pressure in the power supply system and disconnect топливныелинии from a fuel highway. Disconnect also all vacuum hoses and hoses of system of cooling from the inlet pipeline/case of a throttle; Remove a basic arm from an inlet collector, also remove the top arm of fastening of the generator; Disconnect an accelerator cable; Disconnect from a final collector a reception pipe of system of release of the fulfilled gases in gathering with a basic arm; Disconnect electroconducting from a ljambda-probe. Uncover газораспределительного the mechanism (see Has undressed Removal and cover installation газораспределительного the mechanism). Remove a camshaft cogwheel (see Has undressed Removal and installation of cogwheels of drive ГРМ). Turn out bolts of fastening of a back cover of drive ГРМ to the case газораспределительного the mechanism. On engine C14NZ separate sockets of electroconducting and ВВ cables from the ignition distributor. On engines X12SZ and C14SE separate sockets of electroconducting at the module of ignition DIS. Give a bolt of fastening of the tyre of grounding in a forward part of a head and remove from a head a protective casing of electroconducting. Release fixing collars and disconnect hoses of system of cooling from a thermostat casing. Make sure that all hoses, tubes, wires and other lines of communication are disconnected and do not disturb to dismantle of a head of cylinders. Operating in an order, the return shown on an illustration, gradually, on a turn quarter for the approach, ослабьте bolts of fastening of a head of cylinders so that there was a possibility of their reversing manually. Remove bolts from a head in the complete set with the washers. Having lifted upwards, separate from a head the case газораспределительного the mechanism, - in case of need обстучите the case from sides a hammer with soft brisk. At all do not hook the case the lever in order to avoid damage of interfaced surfaces! Mark position of two directing plugs, remove them from a head and clean in a reliable place. Separate a head of cylinders from the block, - try not to drop levers of a drive of valves and маслоотражательные caps. In case of need slightly обстучите a head from sides a hammer with soft brisk, - at all DO NOT HOOK its lever! Mark position of two directing plugs, remove them and clean in a reliable place. Remove a sealing lining, - yet do not throw out a lining for the purpose of identification on it new.

Preparation for installation

PERFORMANCE ORDER

Carefully smooth out and dry wipe interfaced surfaces of a head and the block of cylinders. Use a firm plastic or wooden scraper for removal of all traces of a material of an old lining and a deposit. 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. 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. 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. Bolts of fastening of a head are subject to replacement without fail, without dependence from their current condition. By means of a steel ruler and щупа лезвийного type check up planeness of an interfaced surface of a head (the Part the General and engine major repairs see). Replace bolts of fastening of a head of cylinders, - bolts are subject to replacement without fail without dependence from their current condition.

Installation

PERFORMANCE ORDER

Result the piston of the first cylinder in position ВМТ of the end of a step of compression. Pure rags dry wipe interfaced surfaces of the block and a head. Make sure of that both directing plugs are established in the nests. Lay on an interfaced surface of the block of cylinders a new sealing lining, - the lining keeps within marks by a mark OBEN/TOP upwards. Correct position of a lining of a head of cylinders Establish a head on the block of cylinders - track correctness of hit of directing plugs in reception nests. Dry wipe pure rags interfaced surfaces of a head and case GRM. Make sure of correctness of installation of levers of a drive of valves, маслоотражательных caps and hydraulic jacks. Put a layer of hermetic OPEL ET - № 15 03 166 on the top interfaced surface of a head of cylinders. Hermetic drawing on a surface of a head interfaced to case GRM Establish directing plugs and grease with pure impellent oil levers of a drive of valves. Accurately establish case GRM with the camshaft enclosed in it on a head of cylinders, track correctness of hit of directing plugs in reception nests, - track correctness of hit of directing plugs in reception nests. Put on NEW bolts of fastening of a head of cylinders of a washer, then screw bolts and tighten them by hand. Operating in strictly certain sequence, in in regular intervals, tighten bolts according to specification requirements. Order of a tightening of bolts of a head of cylinders Screw bolts of fastening of a back cover of drive ГРМ and tighten them with demanded effort. Establish a camshaft cogwheel (see Has undressed Removal and installation of cogwheels of drive ГРМ) and газораспределительный a belt (see Has undressed Removal and installation of a belt of drive ГРМ). Restore initial connection of electroconducting, track correctness of a lining of plaits and reliability of their fastening in all provided intermediate clamps. Connect to the case of the thermostat hoses охладительного a path, - track reliability of a tightening of fixing collars. Establish to the place of the inlet pipeline and a final collector (see the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases). Establish into place protection картера and the right forward wheel. Lower the car on the earth and tighten wheel bolts with demanded effort. Make sure of correctness and reliability of connection of all hoses, then make refuelling of system of cooling (see the Head of System of cooling of the engine, salon and air conditioning heating). Connect the storage battery. Start the engine and check up it on presence of signs of development of leaks of working liquids.
