LUCAS 25D/45D DISTRIBUTORS
1. Turn engine to top dead centre using
the appropriate timing marks on your car (usually on the crankshaft pulley).
Ensure that the rotor is pointing to No. 1 spark plug lead. If it is pointing
to No. 4, give the engine a further rotation to bring it to No. 1. Mark
position of old distributor (then, at anytime you can put everything back
as it was)
2. Disconnect the low-tension wire from
your distributor and remove the vacuum pipe. Undo the distributor clamp
plate and remove the old distributor
3. Loosen the clamp pinch bolt on your
new distributor. The distributor is supplied with a single bolt clamp,
you can use this or, if you prefer you can remove it and use your original
clamp. Apply a small amount of oil and insert new distributor, it has
an offset tooth that can only be engaged in one position. If you encounter
problems inserting it, remove the 0 ring from the shaft on the distributor,
wrap some coarse grit wet/dry paper around the shaft and twist the distributor
a few turns to remove any imperfections or burrs. Replace the 0 ring ,
and try to insert again.
4. Remove cap and rotate the distributor
body until the rotor points roughly towards No. 1 spark plug lead. Tighten
the bolts sufficiently to stop it from turning freely but still allowing
5. Refit cap and leads .Reconnect the low-tension
wire to the black wire on the distributor. Connect the red wire on the
distributor to the positive terminal on the coil. If your car is fitted
with a ballast wire or resistor, it is preferable to take the feed directly
from any switched 12 volt feed BEFORE the resistor or wire in the loom
(if you are unsure, you can take a feed directly from the back of the
ignition key). To give an original appearance, tape the red wire into
the loom with insulation tape. If there is no spare terminal on the coil,
use the spade connector provided to bolt to the coil which will then enable
you to connect the new distributor
6. Attempt to start car. If it does not
start, rotate the distributor a small amount at a time to the left or
the right. When the car is running, turn the distributor to obtain the
fastest, smoothest idle.
7. Use strobe to check and set timing.
When satisfied, refit vacuum pipe.
Note: AccuSpark 45D distributors are fitted
with a combined rotor/trigger. Spares are available from our website.
The box also contains a spare trigger which is used with an original type
