4.1.1. Removal of the power unit
Disconnect wires from the storage battery. Establish the car on the lift. Dump pressure in a power supply system for what remove the relay of turning on of the fuel pump, start up the engine and let's to it work to a full stop. Merge liquid from cooling system. Merge oil from a transmission.
If the engine is subject to dismantling, merge oil from the engine and remove the oil filter. Remove a radiator together with branch pipes and the fan of system of cooling, having left on a place a broad tank.
Remove the generator and disconnect wires from a starter. Remove the pump of the hydraulic booster of a steering and, without disconnecting hoses, suspend it in a motor compartment.
Remove forward wheels. Remove protective guards from under the car bottom. Remove a cowl. Remove the air filter. Disconnect топливопровод and hoses fuel plum from the fuel highway, previously having pressed them clips.
Fig. 2.1. Suspension bracket of the power unit: 1 — a forward cross-piece of a body; 2 — a damper of fluctuations (on cars with an automatic transmission); 3 — a back support of the engine; 4 — an arm of a back support of the engine; 5 — a suspension bracket bracket; 6 — an eye for engine lifting; 7 — the right support of the engine; 8 — an arm of the left support of the engine; 9 — the left support of the engine; 10 — a forward support of the engine (at cars with a mechanical transmission); 11 — an arm of a forward support of the engine
Muffle all openings to prevent dirt hit in a power supply system. Disconnect a cable of management of a butterfly valve, separate electrosockets on the butterfly valve case, an inlet collector and auxiliary devices. Remove wires from a collector and a head of the block of cylinders. Disconnect vacuum hoses, branch pipes of system of cooling and all other hoses of ventilation from a collector and the corresponding valves. Remove arms of fastening of an inlet collector and remove a reception pipe of the exhaust silencer. Unclench collars of fastening and disconnect hoses of a heater and other hoses of system of cooling from the engine, previously having remembered or having written down their situation. On cars with the conditioner turn out bolts of fastening of the compressor and remove it from the engine, without disconnecting from it pipelines. Adhere the compressor a wire to elements of a body of the car to avoid load of pipelines after engine removal. Separate electrosockets of the distributor, the coil of ignition and the block of power transistors. Release a bunch of wires from brackets of fastening and take wires aside from a head of the block of cylinders. Disconnect shaft of a drive of forward wheels and a cable of a drive of coupling from a transmission. Disconnect from a transmission connecting draft, draft of a drive of gear shifting, the flexible roller of a drive of a speedometer and electric sockets. To Zastropita also raise the power unit. Disconnect fastenings of arms of a suspension bracket of the power unit (fig. 2.1)
Be convinced of that all electric wires and auxiliary units are disconnected from the engine before starting dismantle of the power unit.
Be convinced of that connecting draft and draft of a drive of gear shifting are reliably fixed not to damage them at removal of the power unit. Establish a transmission jack or the cargo cart under the power unit, lower and deduce it from under the car.
This operation should be carried out together with the assistant as there can be a need slightly to incline the power unit that it was not hooked for panels of a body of the car.
In need of a transmission detachment from the engine establish the power unit on wooden whetstones or arrange on a workbench. Turn out bolts of fastening and remove a starter from a transmission. Be convinced that the engine and a transmission are reliably fixed. Turn out bolts of fastening of a transmission to the engine, previously having remembered or having written down the provision of bolts and arms. Carefully separate a transmission from the engine. Be convinced that the transmission does not hang on primary to a shaft. Whenever possible remove adjusting pins from a transmission and keep them.
