INTRODUCTION
t • The overdrive is an additional gear unit between the gearbox and propeller shaft. When in operation it
provides a higher overall gear ratio than that given by the final drive crown wheel and pinion.

The primary object of an overdrive is to provide open·road cruising at an engine speed lower than it
would be in normal top gear. This reduced engine speed gives a considerable reduction in petrol
consumption and increase in engine life. Overdrive may also be l:lsed on the indirect gears to enhance
performance or to provide easy and c1utchless gear changing, for example in town traffic.
The overdrive is operated by an electric solenoid controlled by a switch, usually mounted on the
steering column or fascia panel. An inhibitor switch is fitted in the electrical circuit to prevent en-
gagement of overdrive in reverse, and some or all of the indirect gears.
Overdrive can be engaged or disengaged at any speed. but usually above say 30 m.p.h. in top gear. It
should be operated without using the clutch pedal and at any throttle opening because the unit is
designed to be engaged and disengaged when transmitting full power. The only precaution necessary
is to avoid disengaging overdrive at too high a road speed, particularly when using it in an indirect
gear, since this would cause excessive engine revolutions.

It will be seen that it is no longer in contact with
the annulus but has moved forward so that its
outer friction lining is in contact with a brake ring
forming part of the overdrive casing. The sun-
wheel to which the clutch is attached is therefore
held stationary. The planet carrier rotates with the
input shaft and the planet wheels are caused to
rotate about their own axes and drive the annulus
at a faster speed than the input shaft. The uni-
directional clutch allows this since the outer
member can over-run the inner member.
Movement of the cone clutch in a forward direction
is effected by means of hydraulic pressure which
acts upon two pistons when a valve is opened, by
operating the driver controlled selector switch.
This hydraulic pressure overcomes the springs
which load the clutch member on to the annulus
and causes the clutch to engage the brake ring
with sufficient load to hold the sunwheel at rest.
Additional load is again imparted to the clutch
in a forward direction due to the helix angle of the
gear teeth.
The unit is shown diagrammatically in Figs. 2 and 3.
The overdrive gears are epicyclic and consist of a
central sunwheel meshing with three planet gears
which in turn mesh with an internally toothed
annulus. All gears are in constant mesh. The planet
carrier is attached to the input shaft and the
annulus is integral with the output shaft.

." is transmitted from this shaft to the inner member
of a uni-directional clutch and then to the outer
member of this clutch through rollers which are
driven up inclined faces and wedged between the
inner and outer members. The outer member
forms part of the combined annulus and output
shaft. The gear train is inoperative. A cone clutch
is mounted on the externally splined extension of
the sunwheel and is loaded on to the annulus by a
number of springs which have their reaction
against the casing of the overdrive unit. The spring
load is transmitted to the clutch member through a
thrust ring and ball bearing. This arrangement
causes the inner friction lining of the cone clutch
to contact the outer cone of the annulus and rotate
with the annulus, whilst the springs and thrust
ring remain stationary. Since the sunwheel is
splined to the clutch member the whole gear train
is locked, permitting over-run and reverse torque
to be transmitted, Additional load is imparted to
the clutch member, during over-run and reverse,
by the sunwheel which, due to the helix angle of
its gear teeth, thrusts rearward and has for its
reaction member the cone clutch.

l HYDRAULIC SYSTEM
Hydraulic pressure is developed by a plunger type pump, cam operated from the input shaft. The
pump draws oil from an air-cooled sump through a suction filter and delivers it via a non-return valve
through a pressure filter to the operating pistons, solenoid valve and relief valve. Incorporated in the
relief valve is a spring dashpot which ensures smooth overdrive engagement and disengagement
under varying conditions. In direct drive a residual pressure of approximately 40 p.s.i. is maintained
within the system. When overdrive is engaged this is increased to a pre-determined operating
pressure.

LUBRICATION

ENGAGING OVERDRIVE
When the solenoid is energised, its valve opens and oil which is at residual pressure is directed via
passage Z to the bottom of the dashpot piston. This causes the dashpot piston to rise and compress
the springs causing a gradual increase in hydraulic pressure until the piston reaches its stop by which
time the relief valve spring has been compressed to its working length, thus giving full operating
pressure. This pressure.ca-uses the operating pistons to move forward, overcoming the clutch return
springs and engages the cone clutch in the brake ring.

ENGAGING DIRECT DRIVE
When the solenoid is de-energised its valve is closed by a spring, cutting off the oil supply from the
pump to the dashpot. Oil is now exhausted via the control orifice in passage Z which allows the relief
valve spring to relax to its direct drive condition. The dashpot springs continue to move the dashpot
piston to its stop, allowing the system pressure to progressively drop which enables the clutch return
springs to move the cone clutch gently into contact with the annulus.
The residual pressure of approximately 40 p.s.i. is now maintained in direct drive.

L:UBRICATION SYSTEM
Oil is discharged through the relief valve direct to an annular channel in the centre of the main casing
and then through drillings in the mainshaft to the annulus spigot bearing. Immediately in front of the
spigot bearing a radial drilling passes oil through the uni-directional clutch, from here it is directed
by an oil thrower into a catcher disc on the planet carrier and to the planet bearings via the hollow
planet bearing pins. .
A radial drilling in the annulus meters lubricant from the mainshaft axial drilling to the rear bearing in
the Reverse Spline unit. The amount of pressure in the lubrication passage is controlled by the
lubrication relief valve.
MAINTENANCE
When the gearbox and overdrive have a common oil supply, the level should be checked at the
gearbox. To drain this type of system the sump of the overdrive must be removed as well as the gear-
box drain plug. This will provide access to tbe suction and pressure filters, which should also be
removed and cleaned before replenishing with new oil.
When separate oil systems are used for the gearbox and overdrive, an oil filler/level plug is provided
for the overdrive in the adaptor plate. Following complete draining and refilling, run the transmission
for a short period then re-check the oil level.
It is essential that only the approved lubricant is used for topping up and re-filling. ON NO ACCOUNT
SHOULD ANY ANTI FRICTION ADDITIVES BE USED.
CLEANLINESS
Scrupulous cleanliness must be maintained throughout all servIcing operations. Even minute
particles of dust, dirt or lint from cleaning cloths may cause damage or interfere with the correct
operation. When the overdrive and gearbox have a common oil supply, it is naturally as important
that the same high standards of cleanliness must be maintained when servicing the gearbox.
J Great care must be taken to avoid the entry of dirt wh.en topping up or re-filling.
For cleaning externally or internally use petrol or paraffin ONLY otherwise damage may occur to oil
seals and other parts of the unit.
On no account should water be,.-used during cleaning operations as this will also affect the operation
of the overdrive. .

OVERHAUL OF COMPONENTS
ACCESSIBLE WITHOUT REMOVING
OVERDRIVE FROM CAR
CHECKING OIL PRESSURE
After first ensuring that t5e oil level is correct
remove the plug adjacent to solenoid and fit
hydraulic pressure gauge (L.188) together with
adapter (L.188-2). With the car jacked up run the
transmis~ion at approximately 25 m.p.h. In direct
drive the residual pressure should register on the
gauge to approximately 40 p.s.i. When overdrive
is engaged, a pressure corresponding with that
specified for the car model in the manufacturers
handbook should be recorded. Disengage ov~r
drive and the gauge should return to show residual
pressure. FIG.6. CHECKING OIL PRESSURE
SOLENOID CONTROL VALVE
The solenoid and operating valve are a self
contained factory sealed unit.
REMOVAL
The assembly can be removed by means of a thin
1 H (25 mm) A/F open ended spanner. DO NOT
ATIEMPT TO REMOVE BY GRIPPING CYLIN-
DRICAL BODY OF SOLENOID VALVE.
INSPECTION
Examine the "0" rings on the solenoid valve for
damage and renew together with sealing washer if
necessary.
TESTING
Test the solenoid coil with a 12v battery and
ammeter. The solenoid should draw approximately
2 amps. Check that the plunger in the valve moves
forward when the solenoid is energised (arrowed)
and is returned to its direct drive position by spring
pressure when de-energised.
NOTE: The solenoid does not operate with a loud
click as in other types of overdrives.
Should it be necessary to clean the operating
valve, immerse this part 61 the solenoid valve in
PARAFFIN until the valve is clean.
If faulty the complete unit must be renewed.

FIG.7. REMOVAL OF SOLENOID
FIG.8. SOLENOID CONTROL VALVE
12. THE ELECTRICAL CONTROL SYSTEM
The solenoid is fed from a control switch in the
ignition circuit and has in series a gearbox isolating
switch. The isolating switch contacts are con-
trolled by the gearbox selector .mechanism, open-
ing them when gears are engaged on which
overdrive is not to be usod, e.g. first and reverse.
FAULT FINDING
Disconnect the live feed to solenoid and connect
a test lamp between this wire and earth. Next
engage top gear and with ignition on put the
manual switch in the engaged position. The test
lamp should now light, if not trace the fault in the
electrical system, e.g. wiring, control or isolating
switch. If the test lamp remains lit when gears are
selected on which overdrive is not used, suspect
the isolating switch.

15. OVERDRIVE UNIT REMOVAL
NOTE: Before commencing overdrive removal it
is advisable to drive the car and engage overdrive
then disengage with the clutch depressed leaving
the overdrive ready for removal. This will release
the spline loading between the planet carrier and
uni-directional clutch which .could make removal
difficult.
If this procedure has not been carried out and
difficulty is experienced in removing the overdrive
from the gearbox shaft proceed as follows. Screw
pressure adaptor L.402 into the pressure take-off
tapping and then energise the solenoid. A grease
gun charged with engine oil can then be used to
pressurise the unit via the pressure adaptor th!Js
releasing the spline loading.
To separate the overdrive from the gearbox
remove the eight t" U.N.F. nuts securing the unit
to the adaptor plate. The overdrive can now be
withdrawn from the mainshaft leaving the adaptor
plate in position on the gearbox.
DISMANTLING
SPECIAL TOOLS
A complete set of special tools can be obtained as
listed in Appendix A. Before starting to dismantle
the assembly, the exterior of the casings must be
thoroughly cleaned.
The overdrive can now be divided into four main
sub assemblies as shown in Fig. (18)..
1. Main Casing and Brake Ring.
2. Clutch Sliding Member, Sunwheel and Bearing
3. Planet Carrier and Gear Train.
4. Rear Casing and Annulus.
To dismantle into these sub assemblies proceed as
follows.
FIG.17. OVERDRIVE SECURING NUTS
(Arrowed)
Mount the unit vertically in a vice. The use of jaw
protectors is recommended.
Next remove the operating piston bridge pieces.
The six nuts securing the main casing to the
rear case can now be removed. These should be
undone progressively to release the clutch return
spring pressure. Note the position of copper
washers which fit on the two studs at the top of the
casing. The main casing complete with· brake
ring can now be separated from the rear case. Next
lift out the sliding member assembly complete
with sunwheel, followed by the planet carrier
assembly, :taking care not to damage the oil
catcher which is attached to the underside of the
carrier. .

REAR CASING, ANNULUS AND
UNI-DIRECTIONAL CLUTCH
(REVERSE SPLINE TYPE)
DISMANTLING
Using a screwdriver blade remove the circlip
retaining the uni-directional clutch. The oil thrower
ring can now be lifted out. Next place tool No.
L.178A over the now exposed undirectional
clutch and lift the inner member complete with
rollers into the special tool. The bronze thrust
washer can now be removed. Next withdraw the
speedometer driven gear and bearing. To remove
the annulus first drive a punch into the welch plug
at the top of the rear casing and lever out. Next
using circlip pliers (7066) and plier points (7066L)
expand the circlip which secures the annulus
bearing. A light blow with a hide mallet upon the
end of the annulus will drive out the annulus
complete with bearing from the rear casing.
Remove the nut securing the speedometer driving
gear and with the aid of a universal extractor
withdraw the ball race. Note the oil weir (arrowed)
is pressed into the rear· case to ensure an adequate
supply of oil to the rear bush and should not be
removed.
INSPECTION
Inspect the teeth and cone surface of the annulus
for wear. Check that the uni-directional clutch
rollers are not chipped and that the inner and
outer members are free from damage. Examine
the spring and cage for distortion. Ensure the
lubrication port to the rear of the annulus (arrow-
ed) is clear. Finally examine the rear casing bush
and oil seal for wear or damage.
FIG. 24. REMOVING ANNULUS
J.
J ASSEMBLY
Fit a new annulus ball race. Next fit the speedom-
eter driving gear with the plain portion facing the
ball race and secure with nut and new locking
washer. Tighten to 50-60 Ibs.ft. Position the ball
race circlip in the rear casing and expand using
circlip pliers (7066) and plier points (7066L). Next
press the annulus through the circlip and into the
casing, using a load of 840 lb. max., until the
bearing is fully home and the circlip is located in its
groove. Care should be taken during this operation
not to damage the rear bush and oil seal. Fit a new
welch plug and secure by striking lightly in the
centre with a suitable size flat faced punch.

ASSEMBLY
Next position the spring and inner member of the
uni-directional clutch into the cage, locating the
spring so that the cage is spring loaded in an anti-
clockwise direction when viewed from the front.
Place this assembly into tool 178A with the open
side of the cage uppermost and feed the clutch in
a clockwise direction until all the rollers are in
place. Re-fit the bronze thrust washer in the recess
in the annulus. Transfer the uni-directional clutch
assembly from the special assembly"tool into its
outer member in the annulus. Re-fit oil thrower
and secure with circlip. Check that the clutch
rotates in an anti-clockwise direction only.

DISMANTLING
First remove the uni-directional clutch as pre-
viously described. Remove the speedometer driven
gear. Next remove the coupling flange nut and
washer then withdraw the flange using a suitable
extractor. The annulus may now be drifted out
using a hide mallet applied to the end of the tail
shaft. The front bearing speedometer driving gear
and spacer will be withdrawn together with the
annulus. The rear bearing and oil seal will remain
in position in the rear casing and can now be
driven out.

ASSEMBLY
Position the speedometer driving gear in the rear
casing with its plain boss facing the front bearing
(NOTE: Speedometer driving gear cannot be
fitted from the rear of the casing). Next press the
front bearing into the rear casing, ensuring that its
outer track abuts against the shoulder in the
casing. Position the annulus with the inner face
resting on a suitable packing piece. Using tool
L.186 press the front bearing together with the
rear casing and speedometer driving gear onto the
annulus until the bearing abuts on the locating
shoulder. Next fit the spacer onto the annulus.
Using tool L.186 press the rear bearing onto the
annulus and into the rear casing simultaneously.
Fit the oil seal using tool L.177. Finally press on
the coupling flange and secure with washer and
self locking nut. Tighten to a torque figure of
120 to 130 Ibs.ft.

.. FINAL ASSEMBLY
NOTE: Jointing compound should not be used
during assembly.
Mount the rear casing assembly vertically in a
vice and insert the planet carrier assembly (Note
the gears can be meshed in any position). Next
place the sliding member assembly complete with
clutch return springs onto the cone of the annulus,
at the same time engaging the sunwheel with the
planet gears. Fit the brake ring into its spigot in the
tail casing using a new joint on both sides. Position
the main casing assembly on to the thrust housing
pins at the same time entering the studs in the
brake ring. Next fit the two operating piston bridge
pieces and secure with four new locknuts. Finany
fit and progressively tighten the six nuts securing
the rear and main casing assemblies, ensuring that
the two top studs (arrowed) are coated with
Wellseal and have copper washers located on
same studs. The clutch return spring pressure will
be felt as the two casings go together. FIG. 31. RE-FITTING MAIN CASEASSEMBLY

RE-FITTING TO GEARBOX
~sing a screwdriver of suitable length rotate the
rnner member of the uni-directional clutch in an
anti-clockwise direction until the splines of this
mef"!1ber are in line with the splines in the planet
carner.
Ens~r~ tha~ the pump cam and planet carrier
retaining clip are correctly located on the main-
shaft: f':Jext engage bottom gear and after fitting a
new Jornt to the front face of the overdrive offer it
uP. to. the gearbox. Rotate the output shaft of the
Unit In a clockwise direction at the same time
applying slight forward press~re until the splines
become engaged.
19
Ensure that the pump strap assembly rides smooth-
ly onto the cam and that the overdrive pus~es
home to the adaptor plate face without excess!ve
force. Next fit and tighten the eight nuts which
secure the unit.
If the overdrive fails to meet the adaptor plate face
by approximately ~" it means that ~he planet
carrier and uni-directional clutch splrnes hav.e
become mis-aligned. In this case remove the Unit
and re-align the splines.
