10.1.5. Head of cylinders

At removal of a head of cylinders on the car it is necessary to disconnect the belt drive of the camshaft in the following order:

Fig. 10-9. Scheme of the drive of the camshaft: 1 — a pulley of a bent shaft; 2 — a generator drive belt; 3 — the lower protective cover; 4 — the cogged pulley of a bent shaft; 5 — an average protective cover; 6 — bolts of fastening of an arm of a tension roller; 7 — a tension roller; 8 — the top protective cover; 9 — a camshaft pulley; 10 — a gear belt; 11 — an arm of a tension roller; 12 — an arm spring; 13 — a pulley of the roller of the drive of the oil pump; And — a tag on the cogged pulley of a bent shaft; In, D — VMT tags on a camshaft drive cover; With — a tag on a pulley of a bent shaft; Е — a tag on a cover of a head of cylinders; F — a tag on a camshaft pulley

— turn a bent shaft before combination of a tag With (see fig. 10-9) with a tag of D on an average protective cover, and F tags on a camshaft pulley with a tag E on a cover of a head of cylinders;
— remove the top protective cover of the belt drive of the camshaft and a cover of a head of cylinders;

Fig. 10-8. Camshaft drive belt tension mechanism: 1 — a tension roller; 2 — an arm of a tension roller; 3 — a tension spring

— remove a spring of 3 (fig. 10-8) of a tension roller, weaken bolts of fastening of an arm 2, take away it in extreme left situation and take off a belt from a camshaft pulley;
— turn off nuts of fastening and remove the case of bearings together with the camshaft, the holder of an epiploon and a pulley;
— turn off bolts of fastening of a head of cylinders to the block and remove a head of cylinders with laying.
At installation of a head of cylinders it is necessary to attach the belt drive of the camshaft in the following order:
Clear the interfaced surfaces of a head of cylinders and the holder of an epiploon of the camshaft of the remains of old laying, dirt and oil. Apply on the surface of a head of tsilidr which is interfaced to the holder of an epiploon, KLT-75TM sealant or sealant similar to it like TV-1215 of Three Bond a continuous zhgutik with a diameter of 2-2,5 mm.
Check whether there is a tag on a pulley of a bent shaft against a long tag on an average protective cover of the belt drive of the camshaft.

Fig. 10-4. Check of coincidence of an adjusting tag on a camshaft pulley with a tag on the case of bearings: And — a tag on a pulley, In — a tag on the case of bearings

Turn the camshaft so that tags on a pulley and the case of bearings were combined (see fig. 10-4). Without forcing down the provision of a shaft, fix the assembled case of bearings on a head of cylinders, tightening nuts in the sequence specified fig. 3-18.
Put on a belt a camshaft pulley. Establish a spring of an arm of a tension roller. Smoothly turn a bent shaft on two turns, keeping a belt in a constant tension and not weakening a belt at a shaft stop. Tighten bolts of fastening of an arm of a tension roller.

Fig. 10-5. Check of coincidence of an adjusting tag on a pulley of a bent shaft with a tag on a camshaft drive cover

Check coincidence of tags (see fig. 10-4 and 10-5). If tags do not coincide, then repeat installation of a belt.
