LUCAS WIRING COLOUR CODE
21st September 1961 |
MGB Mk II - WEAR OF FIBRE COLLAR IN LUCAS ECLIPSE DRIVES
|
|
In order to
comply with the English S.M.M. & T. wiring colour code we have
recently introduced several alterations to our well established
colour code. The most important changes are that brown/yellow is
now used for the "D" cable in the charging circuit instead of
plain yellow and brown/green for the "F" lead instead of
yellow/green. In Current Voltage Regulator circuits the ignition
switch and lighting switches are fed through a brown/white lead
to terminal B instead of brown/blue which is only used for the
feed from the Al terminal on our 2-bobbin Voltage
Regulators.
The colour
yellow with various combinations of tracers is now used for
overdrive circuits.
Due to
increased generator outputs the D cable from generator to
control box has been increased from 28/.012" to 44/.012".
The basic
colours are used for the following circuits -
|
Brown |
Battery & Charging circuits. |
|
Yellow |
Overdrive circuits. |
|
White |
Ignition
circuits. |
Green &
Light Green |
Auxiliary circuits fed through ignition switch
|
|
Purple |
Auxiliary circuits not fed through ignition switch e.g.
Horn and interior lights |
|
Blue |
Head Lamp circuits |
|
Red |
Side & tail lamp circuits & circuits fed through S1 & T
switch. |
|
Black |
Earth connections |
|
It should
be appreciated that the fibre thrust washer Part No 291037
fitted between the Drive Sleeve Head and the screwed shaft on
our Lucas Eclipse Drives wears in service causing an increase in
the “out-of-mesh clearance” of the drive with consequent
speeding up of the starter pinion on engagement, resulting in
increased noise and wear of the flywheel ring gear.
This wear
is particularly evident on the Chrysler range of vehicles which,
contrary to the Lucas recommendation, use an unrelieved or
chamfered ring gear tooth form where the possibility of the
teeth meeting end on is more prevalent.
The
thickness of this fibre washer is .093" and this should be
replaced if found to be worn. When overhauling any starter the
out-of-mesh clearance should be checked. With the Lucas Eclipse
drive this should be 1/16" minimum to 3/16" maximum. In many
instances noisy drives have been quietened by shimming up the
drive at this point by the addition of an extra fibre washer
but, when doing this the out-of-mesh clearance must be checked
to prevent any possibility of the pinion touching the ring gear
when the vehicle is going up hill.
We give a
sketch showing the position of this fibre thrust washer.
