Other reasons are repair cost, possibility of access to the equipment of workshops of car-care center, existence of spare parts, time planned for work, and also personal experience.

Here some of options of performance of major maintenance.

Acquisition of separate spare parts

If check shows that the block of cylinders and the majority of details are in a satisfactory condition and can be used further, the most expedient from the economic point of view is purchase of separate spare parts. The block of cylinders, shatunno-piston group and a cranked shaft should be surveyed especially carefully.

Block of cylinders of an incomplete complete set

The block of cylinders of an incomplete complete set contains the block of cylinders with established by the krivoshipno-shatunny mechanism and piston group. All interfaced details are picked up for the dimensional groups, all gaps correspond to norms. On the block the cam-shaft, the klapanny mechanism, a head of the block of cylinders and hinged units are separately mounted not a part of it ремкомплекта. Costs of machining are minimum or are not required absolutely.

Repair engine (block of cylinders of a full complete set)
