4.2. Проворачивание the engineFor performance of some works with the engine it is necessary, that in cylinders position of pistons has been precisely fixed. Proceeding from the top dead point of the first cylinder exact positions of other pistons are automatically established.
VMT-POSITION of 1st cylinder: the piston of 1st cylinder (on the right concerning a movement direction, in V6 a back row of cylinders) is precisely established in the top dead point if valves of the fourth cylinder are blocked (the final valve is closed, the inlet valve starts to open). Valves of the first cylinder are thus closed. In old engines with the ignition distributor it was possible to check up also ВМТ 1st cylinder by position бегунка the distributor and a flywheel (бегунок the distributor it is established over marks on the distributor case, flywheel marks are co-ordinated with a label on a viewing aperture).

As well as at wheel replacement, raise a forward wheel and establish 5th transfer. If now to rotate the hung out wheel forward the power shaft automatically "works" together with it. It will be easier, if spark plugs (atomizer) are preliminary dismantled. If you do not have possibility "steadily" to raise the car include 5th transfer and cautiously move the car until the piston of 1st cylinder will not be established in position ВМТ.
At acquisition in due course small skill the engine can be turned also by means of a plug-in element – for this purpose arrange this element on a belt pulley of the generator. The engine will be turned better if thus приводные belts are pressed to a belt drive. However at use of such way pay attention to that the engine always rotated in an hour hand direction.

It is possible to establish precisely only the special tool: ВМТ cranked shaft. In workshops Ford sideways in the block of cylinders of the engine screw in adjusting screw VMTT (the special tool 303-507 (21-210). Then turn the engine in a rotation direction until cheeks of a cranked shaft will "densely" not adjoin to an adjusting pin.

On the safe party only with the special tool: experts Ford establish camshafts in ВМТ by means of the special tool (it is specified by an arrow).

Check of spark plugs As carburettor engines differently, than diesel units, concern compulsory ignition spark plugs here define a working step. In former years of a spark plug were very sensitive details which not later than through 12 000 kilometres of run reached the border of working capacity. With the advent of the modern materials, gasoline not containing lead and first of all electronic systems of ignition of high capacity all has thoroughly exchanged. However spark plugs still have "allergy" on humidity, for example, after an engine sink, however run in 60 000 kilometres for them – already a commonplace. Ford also recommends to replace candles through each 60 000 kilometres. Nevertheless never it is necessary to lose track of candles, examine spark plugs each 20 000 kilometres: the expert by the form can already judge candles an engine condition. |
