GENERAL INFORMATION

Prevention

If details of management are used by valves again, it is necessary to establish them on the same places. Not to mix a detail, we recommend to make the panel for their storage. Camshafts are dismantled up at the established head of the block of cylinders.


Removal

PERFORMANCE ORDER
1. Disconnect a "weight" wire (–) batteries.
Prevention

The anticreeping code of radio is thus erased.


2. Weaken maple a ridge belt.
3. Uncover heads of the block of cylinders.
4. Remove a forward casing.
5. Establish the cylinder 1 in VMT.
6. Note the provision of an operating chain concerning each of two chain wheels of camshafts. For this purpose put with paint a stroke on a chain and a chain wheel.
7. Unscrew and remove a gear wheel of an inlet camshaft.
8. Remove an operating chain from a gear wheel of an inlet camshaft.
9. Check, whether there are camshafts in a basic provision. Adjusting openings in diameter of 4 mm at a basic provision of camshafts are placed respectively outside of the upper edge of a head of the block of cylinders (arrow). The regulator of camshafts costs in the spat direction (late).

Prevention

Camshafts remove and establish only in a basic provision. They are very sensitive to a break and consequently should be mounted, whenever possible, without tension.


10. Unscrew covers of bearings of camshafts 1 and 8. Remove covers of bearings.

Prevention

Bolts of covers of bearings at first weaken cross-wise on 1/2 turns, then on one turn weaken all bolts and after unscrew.


11. For dismantling of an inlet camshaft at first remove covers of bearings 9, 12 and 14.
12. Then remove covers of bearings 10, 12 and 13. Thus weaken bolts alternately and slowly, counteraction will not be removed yet.
13. For dismantling of a final camshaft at first remove covers of bearings 4, 5 and 7.
14. At the end remove covers of bearings 2, 3 and 6. And weaken bolts slowly and alternately, counteraction will not be removed yet.
15. Take camshafts.

Installation

PERFORMANCE ORDER
1. All assembly details carefully clean flushing gasoline, clear sealing surfaces.
2. Check tarelchaty pushers.
3. Camshafts and places of support grease with engine oil.
Prevention

At replacement of camshafts watch correctness of their identification. The identifier of camshafts is on installation sites of bearings 3 and 10 behind a bearing cover. The letters following the identifier, represent only designation of technological operation.


4. Establish an inlet camshaft so that the sharp ends of cams in the middle of the third cylinder were directed down.
5. At first mount covers of bearings 10, 11 and 13. Thus tighten bolts cross-wise alternately, respectively, on one turn.
6. Then mount covers of bearings 9, 12 and 14.
7. Impose an operating chain on a gear wheel of an inlet camshaft.
8. Insert into a management chain a gear wheel of an inlet camshaft and fix a new bolt with a fillet with the moment of 20 N of m. Then tighten a bolt a rozhkovy key on 90 °.
9. Check coincidence of the marking put at dismantle on gear wheels of camshafts and an operating chain.
10. Establish a cover of a head of the block of cylinders.
11. Expose time on hours.
12. Set an anticreeping code of radio.
