3.4.4.2. Alternatives

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.

Acquisition of separate spare parts

If inspection shows that the block of cylinders and the majority of details 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 carefully. Even if insignificant wear of the block of cylinders is found, cylinders are subject to an obligatory honningovaniye.

Cranked shaft of a full complete set

This repair kit includes a pereshlifovanny cranked shaft and a set of the pistons adjusted on the size and rods. Pistons are already established on rods. The set of piston rings, radical and shatunny loose leaves also enters into a set. These sets usually contain pistons both standard, and all repair sizes.

Block of cylinders of an incomplete complete set

The block of cylinders of an incomplete complete set contains the block of cylinders with the established krivoshipno-shatunny mechanism and piston group. The set includes new radical and shatunny loose leaves, and all gaps correspond to norms. On a set the available cam-shaft, the klapanny mechanism, a head of the block and hinged units are mounted. Costs of machining are minimum or are not required absolutely.

Block of cylinders of a full complete set

The block of cylinders of a full complete set 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 the case of bearings of a cam-shaft, 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 inlet and final collectors and hinged units are mounted only.


Prevention

Carefully think over what of alternatives to you best of all approaches, before purchase of details consult in a local workshop of car-care center, with suppliers of spare parts, and also with sellers of spare parts.
