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.

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.
