Alternative variants of schemes of regenerative repair of the engine

During independent performance of major repairs of the engine the reader will face the necessity of a choice of the scheme of actions defining total amount and character of forthcoming work most comprehensible to it. Necessity of replacement of the block of the engine, shatunno-piston groups and a cranked shaft is defined by set of various factors the main thing from which is the block condition. To number of the other parametres defining a choice of structure of forthcoming works, concern time and material inputs, presence of necessary spare parts, and also own qualification of the owner of the car, as mechanics.

It is possible to allocate following basic schemes of carrying out of major repairs of the engine:

Repair and replacement of components in an individual order. If the condition of the block and the basic internal components of the engine in the course of survey is found by the satisfactory, most reasonable decision there will be a carrying out of their service in an individual order. Thus it is necessary to check up carefully a condition of the block, a cranked shaft and shatunno-piston groups. Even at very insignificant degree of deterioration of the block, a mirror of its cylinders without fail are subject хонингованию.

Use ремкомплекта a cranked shaft. The set consists their pierced cranked shaft and the complete set of repair rods with the pistons established on them. Piston rings and loose leaves of bearings are applied also. The set can be intended for installation as in the block with cylinders of the standard size, and in the pierced assemblage.

Use of the reduced set of the block of the engine. The reduced set includes the block of cylinders with already established in it cranked shaft and shatunno-piston groups. Thus all bearings of a cranked shaft are completed by new loose leaves, and their working backlashes are precisely adjusted. Further such set is equipped additionally with the camshafts removed from the old engine, components клапанного the mechanism, a head of cylinders and hinged units without any global mechanical works.

Use of the expanded set of the block of the engine. The expanded set represents the reduced set, plus the oil pump, the pallet картера, a head of cylinders with a cover, a camshaft, components клапанного the mechanism and drive ГРМ (cogwheels with газораспределительным a belt) with covers. All provided bearings, epiploons and linings are new, backlashes are adjusted. It is necessary to connect only to the block the inlet pipeline with a final collector and hinged units.

The variant of replacement of the engine in gathering is possible also. Many firm car repair shops offer similar service on exchange base changing the become unfit for use units on new or restored.

Before to stop the choice on any of the listed schemes of performance of major repairs of the engine and to start acquisition of corresponding replaceable components, consult with experts of a firm car repair shop of the company-manufacturer of your car and more skilled motorists.
