Dismantling order

It is the most easier to assort the engine and to make all kinds of works at the portable stand specially intended for repair of the engine. Such stands can be hired often. Before engine installation on the stand it is necessary to remove a flywheel with the coupling mechanism to screw stand bolts in the block of cylinders (картера коленвала).

If the stand is not present to assort the engine it is possible having strengthened it on a strong workbench or on a floor. At dismantling without stand application be very cautious during manipulations with the engine.

If you get the ready restored engine, at first it is necessary to remove all hinged units to establish them subsequently precisely in the same order as well as at independent major repairs. Such units concern:

 – The generator, and arms of the pump of the hydraulic booster and (or) the conditioner compressor (depending on a car complete set);
 – The distributor of ignition, a candle and high-voltage wires;
 – The pump of a cooling liquid and thermostat and radiator hoses;
 – Details of the carburettor or system of injection of fuel;
 – All gauges and electromagnetic valves together with conducting;
 – Soaking up and final collectors;
 – The oil filter;
 – The fuel pump – for carburettor engines;
 – Engine mount details;
 – A flywheel / a leading disk of the hydrotransformer.


The prevention

At removal from the engine of hinged units, with special attention concern those trifles which can facilitate engine assemblage. Put labels on linings, epiploons, remote plugs, pins, bolts, washers, nuts, etc. that at assemblage to establish them in former position.


If the block of cylinders of an incomplete complete set (i.e. the block of cylinders with adjusted both established krivoshipno-shatunnym the mechanism and piston group) it is necessary to remove also a head of the block of cylinders, the oil pallet, the oil pump and chains of a drive of cam-shafts is established.

If it is planned to carry out major repairs with full dismantling the engine it is necessary to disassemble and remove completely details of the internal device of the engine in a following order (if it is not stipulated especially see subsection 3.1.1 and subsection 3.1.2.2.1).

 – Soaking up and final collectors;
 – The oil pallet;
 – Chains of a drive of cam-shafts with asterisks;
 – A head of the block of cylinders;
 – A flywheel;
 – Shatunno-piston group;
 – коленвал.

Before dismantling and performance of procedures of major repairs be convinced, available all necessary equipment and tools. The list of necessary tools is resulted in the beginning of the given management.

Assembly order

Before the assemblage beginning prepare all necessary new spare parts, linings and уплотнители, and also necessary tools and adaptations. Familiarise with the description of procedures of assemblage to imagine volume of forthcoming works and once again to be convinced available all necessary. Besides traditional tools and materials the fixing structure for carving connections also is required. Also liquid hermetic for consolidation of demountable connections in which installation of linings is not provided will be necessary. The manufacturer application of liquid hermetic Genuine Liquid Gasket (is available on sale on car repair shops Nissan) is recommended.

To save time and expenditures of labour, assemblage is recommended to be spent in a following order:

 – A cranked shaft;
 – Pistons in gathering with rods;
 – A head of cylinders and pushers;
 – A mechanism chain (chains) timing;
 – The oil pallet;
 – A flywheel;
 – Hinged units.

Before assemblage all details should be carefully cleared and dried, all defects are eliminated. Details should be laid out on absolutely pure desktop (or to contain in individual packings).
