OPTIONAL EXTRAS
RADIO
For operating instructions, see the radio leaflet provided with the set.
The
set is protected against electrical damage by a 5 amp. fuse housed in the
main lead union.
The aerial mast should always be lowered when the
set is not operating.
HEATER
The heater is of the re-circulating type, with a combined rheostat and
ON/OFF switch on the dash panel to regulate the speed of the fan. At
the right-hand rear end of the cylinder head, under the bonnet, a screwed
cock can be turned to vary the amount of hot water which is supplied to the
heater unit. Shutters on the underside of the heater unit control the downward
flow of air from the heater into the car. Closing the shutters will not affect
the air flow to the demister slots.
OVERDRIVE
Operation
The Laycock de Normanville overdrive unit effects a reduction in overall
gear ratio by means of a train of epicyclic gears which are brought
into action by a hydraulically operated cone clutch.
Movement of the
electrical switch
mounted on the outside of the facia panel will bring the
overdrive into operation.
To take the overdrive out of operation, return
the switch to its original position.
The electrical circuit is only complete
when the gear lever is in the position of top, 3rd or 2nd gears. It should be
remembered that if the overdrive switch is made, returning the gear lever
from third to top gear will automatically re-engage the overdrive unit.
Lubrication
The oil used for both lubrication and for the hydraulic pump is the same
as and connected with that of the gearbox.
The two units also having a
common filler orifice in the gearbox.
Draining
There is a drain plug fitted to the overdrive unit, and when draining the
gearbox it is necessary to remove both the drain plug on the gearbox and
the drain plug on the overdrive unit.
WIRE WHEELS
Cars fitted with wire wheels have detachable hub extensions each secured by
four nuts.
These should be checked occasionally for tightness and especially
after the first 500 miles from new or when replacement parts are fitted.
The correct tightness is 60-65 ft. lb.
