3.1.2.5. Alternatives of major maintenance of the engine

GENERAL INFORMATION

At independent performance of major maintenance various options are possible. The decision on replacement of the block of cylinders, shatunno-piston group and a cranked shaft depends on a number of factors from which the most important is the condition of the block of cylinders. 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. Even if insignificant wear of the block of cylinders is found, cylinders are subject to an obligatory honningovaniye.

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)

The repair engine delivered in the spare part contains all set of the block of cylinders of an incomplete complete set, and also the oil pump, the oil pallet, a head of the block of cylinders, a cover of a head of the block of cylinders, a cam-shaft, the klapanny mechanism, gear wheels of a drive of a cam-shaft, a gear belt and belt covers. All details are established with new bearings, consolidations and laying. On a set soaking-up and final collectors and hinged units are mounted only.

Carefully think over, what of alternatives to you best of all approaches, before purchase or before registration of the order for spare parts consult in a local workshop of car-care center, with suppliers of spare parts, and also with experts in restoration of engines.
