The execution of most of the work is based on the condition that the engine is installed in the car. Therefore, if this information is used in a complete overhaul of the engine, when it has already been removed, many of these works will not be performed.
Engine
Engine - 4-cylinder, in-line, with an overhead camshaft, mounted transversely in front of the car.
The cylinder block is cast iron. On the E7J engine, replaceable wet liners are used, and on the K7M engine, ordinary dry liners are used, which are drilled directly into the cylinder block on five main bearings. Thrust washers are installed in the upper central main bearing, which regulate the axial clearance of the crankshaft.
The connecting rods are fixed on the crankshaft by means of connecting rod bearings with liners, and on the pistons - by piston pins, which are fixedly planted in the connecting rods. The pistons are made of aluminum alloy - and are equipped with three rings, two compression and one oil scraper.
The camshaft rotates in five bearings drilled directly into the cylinder head and is driven from the crankshaft by a timing belt that also drives the water pump. The camshaft operates the valves through rocker arms mounted on an axle attached to the top of the cylinder head.
Completely closed crankcase ventilation system.
Lubrication - supply under pressure from an oil pump, which is driven by a chain from the crankshaft.
Repair procedures performed without removing the engine from the vehicle
- a) Removal and installation of a head of the block of cylinders.
- b) Removal and installation of a toothed drive belt and gear wheels.
- With) Camshaft seal replacement.
- d) Removal and installation of the camshaft.
- e) Removal and installation of the pressed steel oil pan.
- f) Removal and installation of connecting rods, pistons and cylinder liners - pressed steel sump.*
- g) Removal and installation of the oil pump - pressed steel sump.
- h) Replacing the crankshaft seal.
- i) Replacement of the supporting elements of the engine.
Note. Although the actions marked with an asterisk can be performed by the engine in the car (after removing the tray), However, it is better to do this on a removed engine. On engines with an aluminum sump, the engine/transmission must first be removed from the vehicle before the sump and remaining components are removed.
