Removing
Remove the hood.
Remove the battery, engine mounts and drain the coolant.
Pic. 3.27. The sequence of removal of components and assemblies when removing the engine from the car: 1 – a wire of the negative plug of the storage battery; 2 - air filter; 3 - fuel line; 4 - return fuel line; 5 - throttle cable; 6 - speedometer drive cable; 7 - clutch cable; 8 - wire connecting the engine with «weight»; 9 – a hose of the vacuum amplifier of brakes; 10 – the three-way valve of the hydraulic booster of a steering and an arm; 11 – heater hoses; 12 - fan and radiator; 13 - expansion tank and washer tank; 14 - generator; 15 - air conditioning compressor; 16 - hydraulic booster pump; 17 - drive shafts; 18 – draft of a gear change (Manual Transmission); 19 - extension rod (Manual Transmission); 20 - flexible connections of the exhaust system, bolts and nuts; 21 - torsion limiter of the engine mount; 22 - power unit assembly
Remove the air filter (pic. 3.27).
Disconnect the fuel supply and output pipes from the fuel pump.
Disconnect the air and throttle actuators.
Disconnect the speedometer cable.
Disconnect the clutch cable (Manual Transmission) or control cable (Automatic transmission).
Disconnect the transmission wire from the transmission «weight» car.
Disconnect the vacuum brake booster hose.
Remove the plugs from the vacuum switches and remove the bracket.
Disconnect the hoses from the heater.
Remove the plugs from the traction relay and vacuum sensor (if any) and turn them out of the fire barrier.
Disconnect wiring connectors from engine.
Disconnect all other electrical connectors in the engine compartment.
Disconnect the wire from the ignition coil.
Disconnect the evaporator hoses from the tank (if they are designed).
Disconnect the radiator hoses, disconnect the connector from the radiator fan motor.
Remove the radiator.
Remove expansion tank and washer tank.
Remove the alternator and air conditioning compressor from the bracket (if provided by design). Move the compressor to the side, being careful not to damage the hoses (are under high pressure), and secure it with a piece of wire.
Raise the front of the car and put it on stands, remove the front wheels and mudguards.
Remove the power steering pump (if provided by design) together with hoses, take aside and secure with a piece of wire.
Drain the gearbox oil.
Disconnect the front stabilizer bar link and push or pull the drive shafts out of the transmission. To fix the position of the differential gears, instead of the drive shafts, insert special plugs or internal constant-velocity joints of the drive shafts into the gearbox.
On manual transmission models, disconnect the shift linkage and linkage extension from the transmission.
Disconnect the exhaust pipe from the muffler.
Remove the rubber plug and mudguard, unscrew the bolt and remove the swivel assembly. Remove the timing belt covers from the timing belt.
Attach the lift arms to the engine.
Disconnect the engine from the suspension mounts.
Raise the engine slowly and carefully, while lifting, the assistant should move the engine forward from the muffler studs and move the wiring aside.
After lifting the engine from the engine compartment, lower it to a platform suitable for further work. Remove the gearbox and differential assembly from the engine. Fix the engine in a vertical position or mount it on a stand.
Installation
Establish on the engine a transmission in gathering with differential.
The front of the vehicle must be in a raised position to allow access from below during installation.
Hang the engine just above the engine compartment, carefully and slowly bringing it into position.
Further work is carried out with two assistants. The first directs the power unit so as not to damage the main brake cylinder by the gearbox and so that the engine enters the muffler studs, and the second holds the power unit so that the hydraulic booster pump is not damaged when lowered.
Further installation is carried out in the reverse order of removal.
Separation of the gearbox from the engine
Automatic transmission
Remove the starter.
Turn away bolts of fastening of an arm of a hinged shaft. The drive shaft must remain inserted into the gearbox, otherwise the differential may fall into the gearbox housing.
Remove the torque converter cover.
Block the flywheel with a large screwdriver behind the ring gear, unscrew the torque converter mounting bolts by turning the crankshaft with a wrench on the pulley mounting bolt and bringing each bolt to the same place.
Loosen the gearbox-to-engine bolts.
Insert a large screwdriver between the engine and clutch housing, disconnect the housing by disengaging it along the entire length of the joint with a screwdriver, and remove the gearbox. To maintain differential position, have a second person hold the driveshaft while removing the transmission from the engine.
The gearbox is installed on the engine in the reverse order of removal.
Manual Transmission
Remove the starter.
Turn away bolts of fastening of an arm of a hinged shaft.
Remove the clutch cover.
Remove the gearbox from the engine. Have an assistant hold the driveshaft. Do not allow the gearbox to rest on the input shaft, otherwise it may be damaged.
When installing, first make sure the centering of the clutch disc is correct. Apply grease to the input shaft splines.
Install the gearbox on the engine, again asking the assistant to hold the drive shaft. If the input shaft does not fit into the splined flange of the clutch disc, turn the crankshaft or transmission input shaft slightly until the splines are aligned. Until the box is fully seated, rest it on the block so that the weight of the box is not perceived by the input shaft.
Tighten bolts of fastening of a transmission to the engine and bolts of a hinged shaft, establish a starter.
