2. Fit new timing chain to crankshaft and camshaft sprocket
which can be secured to the camshaft with the two bolts and the
locking plate.
3. Check the valve timing, ensuring that the timing mark on
the camshaft sprocket aligns with the woodruff key on the crankshaft
(Figure 12).
Operation 8 Camshaft sprocket alignment
1. First ensure that the timing mark on the camshaft sprocket
aligns exactly with the woodruff key on the crankshaft to align with
either no. 1 or no. 4 piston on TDC.
2. Release the locking plate, unscrew two bolts and remove
the locking plate and screws.

3.
Ensure that the timing mark, a notch, on the camshaft end
aligns with the woodruff key on the crankshaft. (Figure 13)
4. Remove the crankshaft woodruff key.
5.
Temporarily refit both sprockets.
6. Check the alignment by placing a straight edge across the
teeth of both sprockets.
7.
Correct any misalignment by fitting an alternative spacer
shim behind the crankshaft sprocket. Alternative spacer shims are
available in increments of 0.127 mm (0.005 in).
8. Remove the sprockets.
9. Refit the woodruff key.
10. Fit a new camshaft sprocket locking plate, refit the bolts
and bend the tabs to lock them.
Operation 9 Cylinder head removal (with engine in car)
1. Disconnect battery.
2. Remove heater fresh air hose.
3. Drain cooling system.
4. Release the two retaining clips and remove air cleaner body
and element.
5. Remove air cleaner base plate from carburettor.
6. Remove the oil filler cap and disconnect the breather hose
from the carburettor.
7. Disconnect the heater and inlet manifold heat exchanger
hoses from the water pump.
8. Remove the radiator top hose.
9. Remove the distributor cap and leads.
10. To allow easier access, remove the distributor via the single
fixing bolt holding the clamp to the cylinder block.
11. Remove the rocker cover nuts and rocker cover, complete
with heater hose and fuel pipe clips.
12. Remove the petrol supply pipe from the carburettor plug to
avoid dirt ingress. Remove the pipe from the clip on the side of
cylinder head and tie back clear of the engine to improve access.
13. Disconnect the lead from the temperature gauge sender on
the thermostat housing.
14. Disconnect the accelerator cable from the bracket on the
carburettor and pull clear.
15. Disconnect the choke cable from the carburettor.
16. Disconnect the heat exchanger hoses from the exchanger.
17. Disconnect the advance/retard pipe and flame trap (if
fitted) from the carburettor.
18. Disconnect the accelerator return spring from the
carburettor.
19. Remove the nut securing the carburettor abutment bracket
to the carburettor.
20. Remove the remaining nut securing the carburettor to the
manifold. Remove the carburettor with gasket.
21. Remove the nuts and washers and detach the heat
exchanger adapter from the inlet manifold.
22. Remove the drip tray complete with gasket.
23. Remove the four nuts securing the rocker shaft assembly
and detach the rocker shaft.
24. Remove the eight push rods keeping them in the correct
order.
25. Remove the two brass nuts and disconnect the exhaust
downpipe from the exhaust manifold.
26. Remove the three small cylinder head nuts with washers on
the spark plug side of the head.
27. Remove the three bolts and washers holding the
thermostat cover on to the head.
28. Remove the dipstick support bar and earth cable from the
long cylinder head stud.
29. Remove the 12 nuts and washers securing the cylinder head
to the cylinder block.
30.
Carefully lift the cylinder head complete with inlet and
exhaust manifolds from the cylinder block.
Replace in reverse order, after scrupulously cleaning the mating faces
and fitting a new gasket. To ensure a good seal when replacing the
cylinder head, smear grease around the metal rings of the gasket bore
eyelets.
Tighten the cylinder head nuts progressively up to a torque of 3.46
kg/m (25 lb/ft) in the sequence shown in Figure 14. The three smaller
nuts along the spark plug side of the head should be tightened to a
torque of 2.07 kg/m (15 lb/ft).
