In this part of Head types of works on repair of the engines which are carried out directly on the car are described. If the engine acted in film from the car and understood, some preliminary operations on dismantling can be excluded.

Engines 1,4 and 1,6 of l belong to the GA series, established on Nissan cars. Engines 16-klapanny with the top arrangement of the valves, four rowed cylinders and two cam-shafts. The engine settles down across a car axis, in its forward part. Transmission is established on the left side of the engine.

Crankshaft 5-basic. Axial люфт the crankshaft it is regulated by selection of the persistent half rings established on the top half of the average radical bearing.

Shatunnye bearings consist of two loose leaves inserted into a rod and in a cover of a rod. Rods are connected to pistons by means of fingers which freely move in a head of a rod and fixed by spring lock rings. Pistons are cast from an aluminum alloy, on pistons three rings – two kompressionny and one maslosjemny are provided.

Inlet and final valves are closed under the influence of spiral springs and move in the directing plugs pressed in a head of the block of cylinders together with saddles of valves. At the increased wear of a saddle and the plug it is possible выпрессовать and to replace new.

Cam-shafts have a drive from a chain and operate 16 valves through pushers of badeyny type. Pushers are established under cam-shafts. Gaps in valves are regulated by selection of special washers for thickness. The bottom support of necks of cam-shafts are the beds chiseled in inflow of a head of cylinders.

Greasing of the engine is carried out from the oil pump with a drive from a crankshaft sock. Oil passes through a maslopriyemnik with the filter of rough cleaning, further through the filter of thin cleaning screwed in the block of cylinders of the engine, and moves to lubricant canals in the block of cylinders and a crankshaft case from which goes to radical bearings of the crankshaft and to basic necks of a cam-shaft. Bearings are greased with Shatunnye under pressure through openings in the crankshaft. Cam-shaft cams, cores of valves and other details of the engine are greased with a razbryzgivaniye.
