13 Engage the timing chain with the teeth of the crankshaft sprocket. Then locate the camshaft sprocket within the upper loop of the chain in such a way that when the sprocket is pushed onto the camshaft, the timing marks will be in alignment.
19 Never smear grease on the gasket as, when the engine heats up, the grease will melt and may allow compression leaks to develop. 20 The cylinder head gasket cannot be fitted incorrectly due to its asymmetrical shape, but the word ALTO should be uppermost in any event (photo).
9 Pistons/connecting rods - removal and refitting 3 1 Remove the cylinder head as described in Section 7. 2 Remove the sump pan as described in Section 8. 3 Undo and remove the big-end cap retaining bolts and keep them in their respective order for correct refitting.
24 Screw in the big-end bolts and tighten to the specified torque (photo). 25 Refit the sump pan (Sec 8) and the cylinder head (Sec 7). 26 Refill the engine with oil and coolant. 10 Oil pump - removal and refitting 1 1 Remove the sump pan as described in Section 8.

used to check bore wear and taper against the Specifications, but this is a pointless operation if the engine is obviously in need of reboring due to excessive oil consumption. 5 Your engine reconditioner will be able to re-bore the block for you and supply the correct oversize pistons to give the correct running clearance.
clearance and end gap. Both clearances should be checked with a feeler gauge. Check the end gap when the ring has been pushed squarely down the cylinder bore for two or three inches (photos).
Oil seals and gaskets 49 It is recommended that all gaskets and oil seals are renewed at major engine overhaul. Sockets are useful for removing or refitting oil seals. An arrow is moulded onto some seals to indicate the rotational direction of the component which it serves.
micrometer to trace the cause of the trouble. It is very seldom that any trouble of this nature will be experienced when fitting the crankshaft. 9 Tighten the main bearing bolts to the specified torque wrench settings (photo). 10 Using a dial gauge or feeler blades inserted between a thrust washer and the crankshaft, check the crankshaft endfloat.
17 Screw in the camshaft front bearing lockscrew (photo). Oil pump 18 Refit the oil pump as described in Sec- tion 10. Timing chain and sprockets 19 Fit the timing chain and sprockets as described in Section 6. Fit the Woodruff key to the crankshaft nose.
removed and the weight of the car is again on its roadwheels. 4 Fill the cooling system. 5 Fill the engine with oil. 6 Replenish lost transmission oil.
5 In practice, if several shims have to be changed, they can often be interchanged, so avoiding the necessity of having to buy more new shims than is necessary. 6 If more than two or three valve clearances are found to be incorrect, it will be more convenient to remove the camshaft carrier for easier removal of the shims.
8 Fit the new belt. Start at the crankshaft drive pulley and, taking care not to kink or strain the belt, slip it over the camshaft pulley. The camshaft may have to be turned slightly to mesh the pulley with the teeth on the belt.
head gasket must be fitted (ALTO visible) so that the oil pressure hole in the block is central in the copper ringed cut-out in the gasket (photos). Make sure that the gasket surfaces on head and block are perfectly clean and free from oil, otherwise the heat sealing (polymerisation) process of the gasket cannot take place.
2 The big-end bearing shells can be renewed without having to remove the cylinder head if the caps are unbolted and the piston/connecting rod pushed gently about one inch up the bore (the crankpin being at its lowest point). If these shells are worn, however, the main bearing shells will almost certainly be worn as well.
from the suspension struts and then remove the bolts which secure the hub carriers to the U-clamps at the base of the suspension struts. 23 Pull the tops of the hub carriers down and then outwards and push the driveshafts from them. 24 Unbolt the driveshaft inboard boot retainers and then remove the driveshafts from the transmission.
6 Remove the spring seat (photo). 7 Discard the valve stem oil seal and fit a new one (photo). 8 Remove the remaining valves in a similar way and keep the components in their originally fitted sequence.

Then, using an oil filter strap wrench or similar device to hold the sprocket against rotation, tighten the bolt to the specified torque. Take care not to damage the teeth of the sprocket, which is of fibre construction (photo).
prevent the flywheel turning. Fit the engine endplate (photo). 20 Fit the timing belt sprocket to the front end of the crankshaft (photo). 21 Fit the crankshaft pulley and the nut; tighten it to the specified torque, again jamming the starter ring gear to prevent the crankshaft from rotating (photo).

Fault finding - all engines Note: When investigating starting and uneven running faults, do not be tempted into snap diagnosis. Start from the beginning of the check procedure and follow it through. It will take less time in the long run. Poor performance from an engine in terms of power and economy is not normally diagnosed quickly.

12 The air cleaner on the 1301 cc engine is mounted on the four flange studs of the carburettors, their nuts being accessible after the air cleaner lid has been removed and the filter element extracted. 13 Refitting of all types of air cleaner is a reversal of removal.
6 Carburettors - general 1 The need to completely overhaul a carburettor is rare. A carburettor can normally be kept in good working order if the top cover is removed and the fuel mopped out of the fuel bowl. Individual jets can be removed and blown through.
7 Carburettor idle speed and mixture - adjustment 4 1 All carburettors have their mixture adjustment set in production. The screw is fitted with a tamperproof cap. 2 Under normal circumstances, only the idle speed screw need be adjusted to set the engine idle speed to the specified level.

outwards, they rotate the cam relative to the distributor shaft, and so advance the spark. The weights are held in position by two springs and it is the tension of the springs which is largely responsible for correct spark advancement. The vacuum advance is controlled by a diaphragm capsule connected to the carburettor venturi.
Note the washers above and below the contact assembly (photos). 23 Fit the new contact assembly by reversing the removal operations. 24 Although the points gap is normally set in production, check it using feeler blades when the plastic heel of the movable arm is on a high point of the shaft cam.
5 Condenser (capacitor) - removal, testing and refitting 1 The purpose of the condenser (sometimes known as the capacitor) is to ensure that when the contact breaker points open there is no sparking across them which would weaken the spark and cause rapid deterioration of the points.
Reassembly 14 This is a reversal of dismantling. On Ducellier distributors, make sure that the advance toothed segment is returned to its original setting otherwise the advance curves for your particular engine will be upset. 8 Ignition coil (mechanical breaker ignition) 1 Coils normally last the life of a car.

The hose ends can then be unclipped from the brackets. The mounting brackets, particularly on the body frame, are not very heavy gauge and care must be taken not to wrench them off (photo). 4 With the flexible hose removed, examine the internal bore. If it is blown through first, it should be possible to see through it.
