1. Isolate the battery.
2. Remove the spark plugs and rocker cover.
3. Turn the engine in a running direction until No. 6
piston is at T.D.C. induction stroke, Le. No.6 inlet
and exhaust valves on the rock.
4. Using a thin steel rule, mark off lines from the T.D.C.
line on the crankshaft pulley I 1/8 in. and 2 5/8 in.
(29 mm and 67 mm) on the A.T.D.C. side of the
pulley. The mark off lines should be sufficiently clear
to be observed as timing marks and represent 20° and
45° A.T.D.C. respectively.
5. Remove number six outlet union from the metering
distributor body. (No portion of the rotor hole
should be visible in the outlet port).
6.
Turn the cr~nkshaft in a running direction until the
leading edge of the hole in the rotor just appears on
the upper side of the outlet port hole (the 'cracking'
point); note the crankshaft angle at which this. occurs.
If this 'cracking' point occurs between the lines
marked in 4, Le. 20° - 45° A.T.D.C. the injection
timing is satisfactory; if not, proceed as follows:
7. Remove the metering distributor and pedestal
complete, 12.10.22 (instructions 1 to 8).
8. Insert a finger in the distributor shaft bore and turn
the pinion gear anti-clockwise (towards the engine)
until a full rotor hole is visible through number six
outlet.
9. Continue to turn the gear anti-clockwise until the
rotor hole just disappears from view, and then rotate
the gear one extra tooth.
10. Lower the pedestal and metering distributor into
position and recheck the position of the rotor hole.
NOTE: If the position of the hole is still not correct the
gear may not have been turned sufficiently, therefore
repeat instructions 8 to 10..
11. Secure the pedestal to the cylinder block, refit the
ignition distributor cap and H.T. leads.
12. Reverse instructions I to 4,12.10.22.
