GENERAL INFORMATION

At independent performance of capital repairs various options are possible. The decision on replacement of the block of cylinders, conrod and piston group and a bent shaft depends on a number of factors from which the most important is the condition of the block of cylinders. Other reasons are the repair cost, a possibility of access to the equipment of workshops of car service, 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 satisfactory condition and can be used further, then the most expedient from the economic point of view is purchase of separate spare parts. The block of cylinders, conrod and piston group and a bent shaft should be surveyed carefully. Even if insignificant wear of the block of cylinders is found, cylinders are subject to an obligatory honningovaniye.

Bent shaft of a full complete set

This repair kit includes a repolished bent shaft and a set of the pistons and rods adjusted by the size. Pistons are already installed on rods. A set of piston rings, radical and connecting rods is also included in the package. 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 installed krivoshipno-conrod mechanism and piston group. New radical and connecting rods are included in the package, and all gaps meet standards. On a set the available cam-shaft, the valvate 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 valvate mechanism, cam-shaft drive gear wheels, a gear belt and covers of a belt. All details are established with new bearings, consolidations and laying. On a set only inlet and final collectors and hinged units are mounted.


Prevention

Carefully think over what of alternatives best of all suits you, before purchase of details consult in a local workshop of car service, with suppliers of spare parts, and also with sellers of spare parts.
