Removal

PERFORMANCE ORDER

1. Remove a gear belt. 2. Unscrew two screws and uncover the ignition distributor. Disconnect ventilation hoses картера from a cover of a head of the block of cylinders, then unscrew 20 bolts and uncover heads of the block of cylinders. 3. Fix a camshaft from проворачивания, having established a key on лыски a camshaft, and unscrew a bolt of fastening of a pulley of a camshaft. 4. Remove a camshaft pulley. 5. Similarly remove a pulley from the second camshaft. Do not mix pulleys of camshafts. On a pulley of the camshaft operating final valves, there is label L, and on a pulley operating inlet valves, the label is absent. 6. At removal of the camshaft operating final valves, unscrew two bolts and remove the distributor of ignition from an end face of a head of the block of cylinders. 7. Check up that on covers of bearings of a camshaft there are labels, and at their absence, using a punch, put labels on covers and the top part of a head of the block of cylinders. Before removal note an arrangement of covers of bearings as they should be established in the same position, as well as before removal. 8. Working on a spiral, outside inside, ослабьте covers of bearings of a camshaft on half of turn for each pass before full unscrewing of bolts. It is necessary for gradual and uniform removal of pressure клапанных springs. Pay attention that the cover of the back bearing of the camshaft operating final valves, also supports the distributor of ignition and fastens two nuts. 9. Remove covers of bearings of a camshaft and remove a camshaft from a head of the block of cylinders. Remove sealing rings.

Check

PERFORMANCE ORDER

1. Check up working surfaces of bearings of camshafts and contours of cams of camshafts on deterioration. In the presence of any deterioration replace a camshaft. If camshaft bearings are worn out, it is necessary to replace a head of the block of cylinders. 2. Check up a condition of working surfaces of hydraulic pushers which contact with camshaft cams.

Installation

PERFORMANCE ORDER

1. Apply a thin film greasings on a basis дисульфида molybdenum on contact surfaces of hydraulic pushers of valves and camshafts. 2. Put on interfaced surfaces of forward and back covers of bearings of camshafts №1, 6 and 11 thin layer of hermetic. 3. Establish camshafts in a head of the block of cylinders in such position that adjusting pins for pulleys of camshafts were above. Establish covers of bearings of camshafts on a head of the block of cylinders and fix their nuts. 4. Tighten nuts of fastening of covers of bearings of camshafts by hand, then on a spiral from the centre to edge tighten fastening nuts in certain sequence, turning each nut on half of turn for one pass until each cover will not concern heads of the block of cylinders. Then in the same sequence tighten nuts the demanded moment in some stages. 5. Establish new sealing rings of camshafts. 6. Establish pulleys of camshafts and fix their bolts, having tightened their demanded moment. Keep camshafts from проворачивания in the same way, as well as at unscrewing of bolts. 7. Check up ease and smoothness of rotation of camshafts on a head of the block of the cylinders, established on the engine, be careful, that the opening valve has not hit about the piston. In case the camshaft is not turned, check up correctness of orientation of covers of bearings of camshafts. 8. Establish the distributor of ignition and a cover of a head of the block of cylinders. 9. Establish a new gear belt and adjust its tension. At installation of new camshafts execute обкатку on the modes resulted in subsection 4.2.8.
