Longitudinal section of the VAZ-2103 engine
The engines of the VAZ-21051 and VAZ-21053 vehicles have a camshaft chain drive and a cylinder diameter of 76 mm. Therefore, there are features in the disassembly and assembly of the front of the engine, as well as in the repair of the cylinder block, pistons, cylinder head and camshaft drive.
In addition, a carburetor of type 2107-1107010 is installed on a VAZ-21053 car, which has slightly different jet diameters and adjustment dimensions.
Otherwise, the repair of VAZ-21051 and VAZ-21053 cars is no different from the repair of VAZ-2105 cars.
