Hydraulic proof-readers of inlet and final valves differ on a design (diameter of the last on 0.40 mm of more diameter of the first), - in order to avoid mess at assemblage put removed components in an oil bath, having them as installation on the engine.

Extraction of components of hydraulic proof-readers from the landing nests is the most convenient for making by means of tweezers.


Check

Camshafts

 PERFORMANCE ORDER

1. Measure size of a deflection of a camshaft. Compare results of measurement to requirements of Specifications in case of need make проточку a shaft, or its replacement.
2. Check up подшипниковые shaft necks on presence of signs of deterioration and mechanical damages. In case of need make replacement.
3. Measure external diameter of necks of a shaft and internal diameter of corresponding bearings in a head. By subtraction of result of the first measurement from result of the second define size of a working backlash of bearings. Compare results of calculations to requirements of Specifications in case of need replace a shaft, or a head.

On models DOHC definition of sizes of working backlashes in bearings is made by means of the special calibrated plastic wire (set Plastigage), - follow instructions of manufacturers, do not apply any greasing, fixture tighten with demanded effort, levers of a drive of valves do not establish.

4. Estimate a condition of working surfaces of cams of a shaft. Minor defects can be eliminated by means of an emery paper. Measure height of cams. Compare results of measurements to requirements of Specifications, in case of need replace a shaft.
5. With the help циферблатного a measuring instrument плунжерного type define size axial люфта camshafts. Compare results of measurements to requirements of Specifications, in case of need replace a support of a shaft (engines SOHC), or heads complete with covers of basic bearings (engines DOHC).

Camshaft of the left head of cylinders

In quality оправки at landing of a new epiploon of a camshaft it is possible to take advantage of a face head of the suitable size, or a piece of a pipe of the corresponding diameter


1  — the  Epiploon
2  —  Opravka
3  —  Vykolotka

 


 PERFORMANCE ORDER

1. Grease подшипниковые necks with pure impellent oil and establish a shaft in a head of cylinders.
2. The further assemblage is made as it should be the return to an order of dismantle of components.
3. At installation of a new epiploon in quality оправки the face head of the suitable size, or a piece of a pipe of the corresponding diameter can be used, - оправка should rest only against a face surface of an epiploon. Before installation it is necessary to grease sealing sponges of a new epiploon консистентной with greasing.


Camshaft of the right head of cylinders

 PERFORMANCE ORDER

1. Grease подшипниковые necks with pure impellent oil and establish a shaft in a head of cylinders.
2. Establish a sealing ring.
3. Establish a camshaft support.
4. On models SPFI establish бегунок and a cover of the distributor of ignition.

Definitive assemblage

 PERFORMANCE ORDER

1. Establish assemblages of axes коромысел a drive of valves (see Has undressed Removal, dismantling, check, assemblage and axis installation коромысел, - engines SOHC).
2. Establish components of drive ГРМ (the Section Dismantling of drive ГРМ see, - removal, check of a condition and installation of components).

Filling with oil of nests under landing of hydroproof-readers клапанных backlashes

1  —  Nests
2  —  oil Level

 


 PERFORMANCE ORDER

1. Develop the engine at the stand the left head of cylinders upwards. Fill nests under landing of hydroproof-readers клапанных backlashes pure impellent the small.

At filling of nests with oil the head should be strictly in horizontal position, combustion chambers downwards to exclude probability of hit of air in a cavity of a regulator of pressure of oil after installation of the hydroproof-reader.

2. Taking hydroproof-readers from an oil bath, establish them strictly on the former places. Try not to suppose air hit in assemblages in the course of installation.
3. Plant support of levers of a drive of valves on the regular places and fix their lock rings.
4. Establish одноплечие levers of a drive of valves: one end of the lever is put on a spherical support, another - on a valve core.

 PERFORMANCE ORDER

1. Slightly grease with pure impellent oil of a support of camshafts and establish the last in a head so that that levers of a drive of valves have appeared pressed to the back parties of cams.

If shaft are developed, as it is shown on an illustration at installation газораспределительного a belt shaft of the right head in проворачивании do not require, in the left head the inlet camshaft should be turned on 80 clockwise, final - on 45 counter-clockwise.

2. Establish covers of basic bearings of a camshaft, preliminary having greased their interfaced surfaces with liquid hermetic of type Three-bond 1215.

Put hermetic moderately, trying not to admit its squeezing at installation of covers in маслотоки or on сальниковые a surface!

The remark: Covers should be established according to the identification marks put on them.

3. In stages (a minimum in 2), in strictly certain order, tighten bolts of fastening of covers of bearings of camshafts with demanded effort.
4. Having tightened fixture of support of both shaft, manually check up freedom of rotation of the last in bearings, - turn shaft on a small corner so that valves remained closed.
5. With konsistentnoj greasing grease sealing sponges of new sealing cuffs and запрессуйте the last in the landing nests in forward support of camshafts.

At installation of sealing linings of covers of heads of cylinders liquid hermetic is put on their specified sites пости

1  —  Places of drawing of hermetic

 


 PERFORMANCE ORDER

1. Establish covers of a head of cylinders, - on four opened edges of a sealing lining put are liquid hermetic of type Three-bond 1215. Track, that at installation of covers there was no displacement of linings.
2. Plant in covers of a head of cylinders rubber a sealing lining and establish ignition coils.
3. Establish the gauge of position of a camshaft.
4. Installation of the remained components is made as it should be the return to an order of their dismantle (corresponding Sections of the Management see).
