2.2.6. Options of major maintenance of the engine

Independent repair of the engine can be executed by several options. The decision on replacement of the block of cylinders, pistons / rods in collecting and a cranked shaft depends on several factors, the condition of the block of cylinders is basic of which. Other reasons are the price, availability of a mechanical workshop, availability of spare parts, time for performance of work and level of experience of independent performance of mechanical works.

Number of options treat:

Separate parts - If check of a condition showed that the block of cylinders and the most part of components of the engine can be used again, acquisition of separate parts can be the most economic option. The block of a cranked shaft and pistons / rods should be assembled carefully checked. Even if the block has insignificant wear, surfaces of cylinders should be отхонингованы.

The set with cranked shaft - the Set (if it is available) consists of the ground cranked shaft with new suitable repair loose leaves of radical and shatunny bearings.

Sometimes the restored rods and new pistons enter into such set with rings (such set call “a set for the engine”). If the block in a good condition, necks of a cranked shaft are worn-out or have teases, the set with cranked shaft and other separate parts can be the most economic option.

The small set with the block - the Small set consists of the block of cylinders with cranked shaft and the pistons / rods established on it assembled. New bearings and all gaps are established correctly exposed. Available a camshaft, components of valves, heads of cylinders and hinged knots can be established on the block with insignificant necessary processing in a workshop or without that.

The full set with the block - the "Full" or "big" set includes a small set and the oil pump, the pallet, a head of cylinders, a cover of a head of cylinders, a camshaft, components of valves, cogwheels and a chain (or a belt) the mechanism of a drive of a gazoraspredeleniye. All components have new bearings, epiploons and laying. It is necessary to attach only the inlet pipeline, a final collector and the hinged equipment.

Attentively consider, what option the best for you, and consult in local mechanical workshops, at dealers of spare parts and at skilled masters on restoration of engines before getting or ordering new parts.
