2.2. Removal and installation of the power unit

The power unit consists of the engine and the transmission. Remove it by means of the hydroelevator or a waist, lowering from an engine compartment on the cart. At the same time tips of shaft of the drive of forward wheels are disconnected from the power unit and remain on the car.
You make removal and installation of the power unit in the following order.
Put the car on the elevator and slow down it the lever of the drive of the parking brake system. Establish an emphasis under back wheels, hang out forward wheels and open a cowl.
Before removal of the power unit it is necessary to remove pressure a fuel supply system. For this purpose disconnect a block of a plait of wires of an electrogasoline pump from a plait of wires of system of ignition, start the engine, let's it work to a stop, and then include a starter on 3 with for alignment of pressure in pipelines.
Disconnect a wire of "weight" from the minus plug of the rechargeable battery and from the engine.
Disconnect hoses of a supply and discharge of fuel from tubes on the engine. Close openings of hoses and tubes that dirt did not get to them.
Disconnect an accelerator drive cable from a throttle branch pipe and from an arm on a receiver.

Weaken two coupling collars of 7 (fig. 2.3) and remove a hose of the 10th inlet pipe, having disconnected a hose of ventilation of a case of the engine from its branch pipe.
Turn off a nut and disconnect an air intake hose together with an arm.
Remove the air filter 1 with the sensor 2 of a mass consumption of air, having cut off a knife three rubber support which the filter fastens to a body.
Disconnect from a receiver hoses of selection of depression to the regulator of pressure of fuel and to the vacuum amplifier of brakes.
Disconnect an adsorber purge hose from a throttle branch pipe (if on the car there is a system of catching of vapors of gasoline).
Disconnect wires from a throttle branch pipe, the ignition module, from a plait of wires of nozzles, from a starter and the generator, from all sensors which are available on the power unit and from the backing light switch on the transmission.
Lift the car on the elevator and remove an engine mudguard, having turned off bolts of its fastening to a body.
Merge cooling liquid, having turned off drain traffic jams of the block of cylinders and a radiator at uncovered a broad tank and the open crane of a heater.
Merge oil from the transmission, having turned off a drain stopper.
Disconnect hoses from a branch pipe of a head of cylinders and the thermostat.
Disconnect a coupling drive cable from the transmission.

Take out from semi-axial gear wheels of the transmission tips of internal hinges of shaft 4 (see fig. 2.5) the drive of forward wheels and take shaft aside. It is possible to take out a stripper 67.7801.9524 or sharply striking with the hammer through a drift the case of the internal hinge.
Having disconnected one of shaft, record a semi-axial gear wheel a technological mandrel or a cap that it did not drop out in a transmission case. After a detachment of the second shaft also close an opening a cap.
If the power unit is removed by means of the special cart with the hydroelevator, then bring it under the car and lift basic arms of the hydroelevator against the stop in the power unit.

Turn off bolts of fastening of support of a suspension bracket of the power unit to a body (fig. 2.6) and lower the power unit the hydroelevator down. If it is applied таль, then moving a waist chain, carefully lower the power unit on the cart.
Install the power unit as it should be, the return to removal.

       PREVENTION
Before connection of shaft of the drive of forward wheels with the transmission establish new lock rings on tips of internal hinges. Reuse of lock rings is inadmissible as it can lead to a spontaneous detachment of shaft from the transmission at the movement of the car.

Rubber support of fastening of the air filter of one-time use. Therefore at installation of the air filter establish new support.
After installation of the power unit adjust the accelerator drive. At completely released accelerator drive pedal the butterfly valve has to be completely closed. The cable of the drive has to be tense. The cable deflection from effort of a hand has to be no more than 10 mm. If necessary adjust a tension of a cable of the drive adjusting nuts of a tip of a cable.
At completely pressed accelerator pedal against the stop the butterfly valve has to be completely open, the sector of a butterfly valve should not have the additional course. If necessary eliminate the additional course with a pedal emphasis podgibaniye in interior of the car.
The drive of switching off of coupling adjust as directed subsection. "Coupling". Check and adjust the angles of installation of forward wheels (see subsection. "Forward suspension bracket").
Check work of a control system of the engine as it is specified in the user manual and to repair of a control system of the engine with the distributed fuel injection.
