4.21. Removal and engine installation

The engine take out from the car upwards. For engine removal the elevating device load-carrying capacity not less than 300 kg is necessary. The car needs to be established on the lift, a viewing ditch or a platform. Before engine removal it is necessary to prepare a reliable support on which the engine should stand steadily. The engine is more convenient for taking out if to remove a cowl.

       GOOD ADVICE
Before a detachment of hoses and electric wires it is recommended to mark them not to mix at assemblage.

The Manufacturer recommends to remove the engine, preliminary having separated knots of the power unit: the transmission with картером couplings remains on the car, and at engine removal the forward bearing of a primary shaft of a transmission and a nave of a conducted disk of coupling act in film from a primary shaft.
It be required to you: keys «on 10», «on 13», «on 17» and «on 19» (or a head with extension pieces and карданным the hinge), screw-drivers (two), оправка for a centering of a conducted disk of coupling, пассатижи, таль or other elevating device, slings (a strong cord).

20. Disconnect pad plaits of wires from the gauge of position throttle заслонки...
21.... From an idling regulator...
22.... From a plait of wires of atomizers...
23.... From the gauge of temperature of a cooling liquid of a control system of the engine.
24. Take out holders of a motor plait of wires from apertures of arms on the engine and a body and take a plait aside.
25. Disconnect колодку a plait of wires from the ignition module.
26. Turn away a nut of fastening of plugs of "mass" wires to an arm of the module of ignition and disconnect wires.
27. Disconnect wires from the gauge of emergency pressure drop of oil and...
28.... The gauge of the index of temperature of a cooling liquid.
29. Remove a belt from a pulley of the pump of the hydraulic booster of a steering (Check of a tension and adjustment of a belt of a drive of the pump of the hydraulic booster »see«).
30. Disconnect колодку a plait of wires from the gauge of position of a cranked shaft.
31. Turn out bolts of fastening of an arm of the pump of the hydraulic booster of a steering to the engine (boot Replacement натяжителя chains of a drive of a camshaft »see«), take away an arm together with the pump (without disconnecting hoses) from the engine and fix it on a body in any accessible way (for example, having fixed a wire).

48. Turn out a bolt of the top fastening back распорки an inlet pipe and remove распорку.
49. For fastening slings of the load-lifting mechanism it is convenient to use one of the transport eyes established on the top bolts of fastening crankcase of coupling. Remove an eye from a bolt and fix it on a place of an arm of a "mass" wire of the engine a bolt of its fastening, as is shown in a photo.
50. Using the regular and again established eyes, fix to a sling of the load-lifting mechanism on the engine.

53.... Insert between картером couplings and a bar of the stabilizer of cross-section stability wooden брусок the suitable size (thickness about 60–70 mm), hardly lower the engine so that брусок it has appeared it is clamped between картером couplings and the stabilizer, and shift the engine forward, removing it from crankcase couplings. Thus the forward bearing of a primary shaft and a nave of a conducted disk of coupling will act in film from a primary shaft of a transmission.
54. After a full exit of a primary shaft from a nave of a conducted disk accurately raise the engine and take it from a motor compartment.

 
THE NOTE
So the fixed transmission after engine removal looks.

55. Establish the engine in sequence, return to removal, taking into account the following:
– Before engine installation necessarily check up, how the conducted disk of coupling is centered, having inserted into its nave and in the forward bearing of a primary shaft the mandrel (Removal and coupling installation »see«);
– Dressing on a primary shaft of a transmission a nave of a conducted disk of coupling, be extremely attentive, differently at a warp of the hung out engine the nave of a conducted disk can be damaged;
– At installation special attention turn on that the bottom edge of a forward guard crankcase couplings (it is shown by an arrow) has been got for average steering draught.
