Repair and car operation

Removal, check of a condition and installation of a camshaft from the case газораспределительного the mechanism

Removal

Removal from adaptation application

In the presence of the special adaptation the camshaft can be removed from the engine without preliminary dismantle of the case газораспределительного the mechanism. The adaptation is established on the mechanism case at the removed cover of the last (see Has undressed Removal and cover installation газораспределительного the mechanism) and allows to make отжимание hydraulic jacks клапанных backlashes. Further dismantle of a cogwheel of a shaft (see Has undressed Removal and installation of cogwheels of drive ГРМ), a face cover and a persistent plate is made. Now the shaft can be taken from the case through an aperture in its left end face.

Removal of a camshaft by means of the special adaptation

Before adaptation installation develop a cranked shaft on 90 hailstones. From position ВМТ (the Section of Procedure of repair of petrol engines SOHC without their extraction from the car see) that will allow to prevent risk of damage of the engine as a result of input of valves in contact to the bottoms of pistons.

Removal without application of the special adaptation

Without application of the special adaptation the camshaft can be removed from the engine only in gathering with case GRM. As the case the same bolts, as a head of cylinders, is meant as well dismantle of last (see Has undressed Removal and installation of a head of cylinders).

PERFORMANCE ORDER

Having removed the case газораспределительного the mechanism with the camshaft established in it, on engines X12SZ and C14SE disconnect the ignition module, and on engine C14NZ remove the ignition distributor. Fixture of the module of ignition On engines X12SZ and C14SE turn out fixing bolts and remove the face cover established on the left side of case GRM. Remove from the case a sealing ring, - can throw out it as at assemblage the ring is subject to replacement without fail. Removal of a face cover on the left side of case GRM (the arrow specifies a sealing ring) Measure size axial люфта a camshaft, filling edges measuring щупа between a persistent plate and shaft. If the result of measurement falls outside the limits an admissible range (Specifications in the Head Engines see), the persistent plate should be replaced. Turn out two fixing bolts and take a persistent plate from the case, - try to remember adjusting position of components. Regulating size axial люфта a camshaft the persistent plate-1 fastens on the case газораспределительного the mechanism two screws with heads under прутковый шестигранный a key Cautiously take a shaft from the case, - try not to damage подшипниковые necks and working surfaces of cams. Extraction of a camshaft from the case газораспределительного the mechanism - be careful

Check

PERFORMANCE ORDER

Having removed a shaft, study a condition of working surfaces of bearings of sliding in case beds. In case of revealing of signs of obvious deterioration or задиров, the case is subject to replacement, - check up also a condition of corresponding necks of a shaft. Check up also passableness provided in the case маслостоков. Actually the shaft should not have traces of scratches on necks and working surfaces of cams. If this sort of defects take place, the shaft also is subject to replacement. In case of revealing задиров on working surfaces of cams, study a condition of levers of a drive of corresponding valves (see Has undressed Removal, check of a condition and installation of valves). Make sure of absence of signs of deterioration or development of a persistent plate of a camshaft, in case of need replace a plate.

Installation

If the new camshaft is established, it is necessary to replace all коромысла and all worn out elements клапанного the mechanism.

PERFORMANCE ORDER

By means of a screw-driver accurately take an old epiploon from the landing nest in the case газораспределительного the mechanism. Check up cleanliness of walls of a landing nest, then запрессуйте in it a new epiploon (sealing sponges inside) заподлицо with an external surface of the case. Plentifully grease a camshaft, basic bearings of the case and an epiploon sponge with pure impellent oil, then accurately fill a shaft in the case, - try not to damage cams, necks and epiploon sponges. Fill on the regular place a persistent plate, - track correctness of its combination with проточкой in a shaft pin. Tighten fixing bolts with demanded effort. Check up size axial люфта a shaft On engines X12SZ and C14SE establish a new sealing ring on pure, dry wiped back surface of the case both establish a face cover and tighten bolts of its fastening with demanded effort. On engines X12SZ and C14SE establish on the case the ignition module, and on engine C14NZ establish the distributor of ignition with a new sealing ring. If removal was made with application of the special adaptation, remove it and establish into place a camshaft cogwheel. Return a cranked shaft in position ВМТ and establish газораспределительный a belt (Sections Removal and installation of a belt of drive ГРМ and Removal and installation of cogwheels of drive ГРМ see). If the adaptation was not applied, establish case GRM (see Has undressed Removal and installation of a head of cylinders).
