10.1.2. Assembly of the engine

In cylinders use a set of plugs 02.7854.9500 intended for pistons with a diameter of 79 mm to installation of pistons.
Carry out assembly of a forward part of the engine in the following order.

Fig. 10-3. A camshaft drive cover with the holder (1) of a forward epiploon of a bent shaft. Shooters specified ledges for centering of the holder and a cover of rather bent shaft and the roller of the drive of the oil pump

After installation of a head of cylinders, attach to a cover (fig. 10-3) of the drive of the camshaft the holder of 1 epiploon with laying, without tightening finally a fastening nut.
Attach a camshaft drive cover with laying to the block of cylinders, without tightening finally nuts and bolts of fastening.

Fig. 10-1. Dismantling of a forward part of the engine: 1 — the top protective cover; 2 — a tension roller;       3 — a tension spring; 4 — a camshaft drive belt; 5 — a camshaft drive cover; 6 — the roller of the drive of the oil pump and the distributor of ignition; 7 — a persistent flange; 8 — a pulley of the roller of the drive of the oil pump; 9 — the cogged pulley of a bent shaft; 10 — an average protective cover; 11 — the lower protective cover; 12 — a pulley of the drive of the generator and pump of cooling liquid; 13 — a nut

Center a mandrel 67.7853.9548 provision of a cover concerning the roller 6 (see fig. 10-1) the drive of the oil pump and tighten bolts and nuts of fastening of a cover of the drive of the camshaft.
Mandrel 67.7853.9549 center position of the holder of 1 (fig. 10-3) of a forward epiploon of a bent shaft and tighten nuts of fastening of the holder.
Establish a pulley 8 (see fig. 10-1) on the roller 6 of the drive of the oil pump, without tightening a bolt of fastening of a pulley. Install the cogged pulley 9 on a bent shaft.

       NOTE
The bolt of fastening of a pulley of the roller of the drive of the oil pump has to be established on sealant on TU 6-10-1048 — 73 or TV-1215 sealant of Three Bond.

Collect the case of bearings of the camshaft according to indications of the head "Camshaft and its drive".

Fig. 10-2. Removal of a head of cylinders: 1 — a cover of a head of cylinders; 2 — laying; 3 — the case of bearings of the camshaft; 4 — a persistent flange; 5 — the camshaft; 6 — the holder of an epiploon of the camshaft; 7 — a camshaft pulley; 8 — a head of cylinders; 9 — laying of a head of cylinders

Clear the interfaced surfaces of a head of cylinders and the holder 6 (see fig. 10-2) a camshaft epiploon of the remains of old laying, dirt and oil.

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

Apply on the surface of a head of cylinders 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. Turn the camshaft so that tags on a pulley and the case of bearings of the camshaft (fig. 10-4) were combined. Without forcing down the provision of a shaft, fix the assembled case of bearings on a head of cylinders, tightening nuts in a certain sequence (see fig. 3-18).

       NOTE
It is allowed to launch the engine in 1 hour after drawing liquid laying
.

Attach to the block of cylinders an arm with a tension roller, without tightening finally fastening bolts. Turn an arm in extreme left situation.

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

Turn a bent shaft so that the tag on the cogged pulley coincided with a tag on a cover of the drive of the camshaft (fig. 10-5).
Put on a belt pulleys and a tension roller, draw in an arm of a tension roller to the right and establish a tension spring.
Smoothly turn a bent shaft on two turns, keeping a belt in a constant tension, and at a stop of a shaft hold it, without allowing weakening of a belt. Thus the spring will establish a necessary tension of a belt. Tighten bolts of fastening of an arm of a tension roller.
Check a condition of tags (see fig. 10-4 and 10-5). If tags coincide, then tighten bolts of fastening of pulleys. If tags do not coincide, then repeat installation of a belt.
Adjust gaps between cams of the camshaft and levers of the drive of valves.

Fig. 10-6. Order of tightening of nuts of fastening of a cover of a head of cylinders

Establish a cover of a head of cylinders with laying and tighten fastening nuts in the sequence specified fig. 10-6. Establish protective covers of the belt drive of the camshaft.
Establish a generator drive pulley on a bent shaft and fix it by a nut.
