Taken as a whole, the Triumph TR2s and TR3s represent
one of the most successful sports car designs in history; so successful that, by the early nineteen-sixties, they had helped to
make Standard Triumph the second-best selling imported car
marque in the United States. During the late nineteen-fifties
and early nineteen-sixties, countless fledgling race drivers
gained their early experience in these machines. Among them
was three-time World Champion Jim
Clark, who owned one of
the first-if not the very first-TR3 in
Scotland.
Today, in the nineteen-seventies,
TR2s and TR3s are as
eagerly sought after as they were twenty years ago when the
cars were
in production. This should not be surprising since
there has never been a time during those twenty years when
TR2s and TR3s were not proving their worth. In 1965, fully ten
years after the TR2 was discontinued and almost five years
after the last TR3 had been built, the cars remained highly
competitive in racing. In that year, the Sports Car Club of
America's U.S. F-Production Championship was won by
Brian Fuerstenau in a TR3-with Lee Midgely's TR2 solidly in
second place.
Wise collectors began to acquire
TR2s and TR3s even before
their long and successful history had been written on the race
track.
(As recently as 1975 a TR3 made
the field for The Cham-
pion Spark Plug Road
~acin~ Classic-an event that deter-
mines the ultimate
standings in
U.S. amateur road racing.) In
1970, at a time when the newest TR3 was on the verge of
becoming a ten-year-old relic, well-maintained examples of its
predecessor, the TR2, were already being purchased by collectors for more than the cars had cost when new. The prices of
fully restored
TR3s have since begun to follow suit and will un-
doubtedly
continue to rise as fewer examples of the type
become
available on the open market.
This is as it should be; the
TIP2 and TR3 are landmarks in
the
evolution of the sports car. Before the TR2 arrived on the
automotive scene, enthusiasts of limited means had very few
cars from which to choose. The TR3 was a windfall particularly to sports car-starved Americans who, in buying a Triumph,
could acquire 100-mph capability at a cost little greater than
that required to obtain an 80-mph
MG.TF.
Because the value of TR2 and TR3 sports cars is increasing,
it is impossible to overstate the importance of correct
maintenance and repair.
Unfortunately, original workshop
manuals and owner's manuals have, since the assimilation of
Standard Triumph by British Leyland Motors, become virtual-
ly impossible to obtain. Indeed, original books are now
collec-
.
.
tor's items in their own right. No vintage Triumph enthusiast
would choose to risk one by placing it on an oil-stained
workbench or on a garage floor! A new, readily available and
easily replaceable manual that duplicates the orginal manuals'
This Manual has been compiled in order to meet that need,
thereby supplying complete, accurate, and comprehensive
maintenance and repair data to both car owners and professional mechanics. The
Driver's Instruction Book,
which comprises the first part of this Manual, is similar to the handbook
provided with every new TR3. The
Service Instruction Manual,
which comprises the second-and largest-portion of this
Manual, is the official factory manual and was originally intended for use by dealer service departments. Owners of
TR3s
and the so-called TR3A or TR3B model will find it informative
to read the Foreword to the TR3 Supplement, which appears
on page
419.
Assembly work on small, highly-tuned machines such as the
Triumph sports
cars must be carried out with greater precision
than is commonly practiced on large American cars. Particular
emphasis must be given to the proper use of torque wrenches
and to strict adherence to the tightening torque specifications
which are given in this Manual. A fastener that is too tight can
be worse than one that is too loose-especially on a lightweight
sports car. Stretched or broken bolts and distorted parts, which
result from overtightening by musclebound mechanics, become
a serious concern where the precision fitting of light alloy and
thin-wall iron castings is involved.
The importance of cleanliness cannot be overemphasized.
Under no circumstances should an engine or gearbox be
repaired on the ground or on a garage floor. Thoroughly clean
the exteriors of major components prior to disassembly in
order to keep road dirt and other grime out of the working
parts. No more than a pinch of abrasive dust in a gearbox can
cause rapid failure of the synchronizers and bearings.
During the final assembly of an engine or gearbox, the
cleaned parts should be laid out on a clean workbench that has
been covered with clean sheets of new cardboard or wrapping
paper. The engine or gearbox itself, if not mounted on a special
stand, should likewise be placed on a clean workbench. Sandpapering, valve grinding, or the use of bench grinders should
not be permitted near the area where final assembly is taking
place. If assembly cannot be completed in a day, enclose the
partially-assembled engine or gearbox in a large plastic
bag-such as a new trash bag or a dry cleaner's garment return
bag-so that dust and dirt will be excluded until assembly
work resumes.
By observing these precautions during the maintenance,
repair, or restoration of your TR2 or TR3, you will be preserving the value and the life of a car that is rapidly becoming one
of the classics among post-World War
I1
sports cars. If at any
time you lack the skills, special equipment, tools, or workshop
facilities for making repairs as they are described in this
Manual, we suggest you leave such repairs to an Authorized

THE
TRIUMPH TR3 SPORTS
CAR
FOREWORD
The vehicle has been designed so that a minimum of attention is required to
keep it in satisfactory running order. There are, however, certain maintenance
operations which must be undertaken regularly, and the object of this instruction
book is to assist even the non-technical owner to understand the various
operations required, and so ensure that the vehicle receives regular and correct
attention.
If in any doubt about the vehicle's performance the owner should at once
consult a Triumph dealer, preferably the one from whom the car was purchased.
Triumph dealers are very carefully selected and are suitably equipped to give
satisfactory and expert after sales service.
There is
a
Service School at the factory at which our dealers' representatives
acquire a first hand knowledge of up-to-date service procedure.
Valuable
information is given regarding special methods and equipment which greatly
assists in getting the various operations performed more expeditiously.
SPARE PARTS SERVICE
To ensure the best possible service on replacement parts it is important to
note the following points
:-
(a) The policy of the Triumph Motor Company is not to supply spare
parts direct to the general public, but
all supplies are directed
through
Distributors who, in turn, will supply their Dealers. The name and
address of the Distributors and Dealers can be obtained from the
Service and Spares Directory included with each motor vehicle.
(b) It is recommended that only
C6Stanparts
"
(i.e.,
genuine Standard/
Triumph spare parts)
are used, only these carry a guarantee.
Experience gained by the manufacturers ensures that only highest
quality material is used and the strictest accuracy maintained in
manufacture.
(c) If in doubt about a particular part required, it is always advisable to
give the vehicle commission number and engine number, in addition
to the fullest description possible.

DRIVING
THE
CAR
TO
START THE ENGINE
IMPORTANT-When starting the engine at any time
:
If the engine does not start when the starter is operated,
do not re-
operate until both starter motor and engine have come to rest.
This is to avoid damage to the starter pinion.
Starting when Engine is Cold
Place the gear lever in the neutral position and see that the handbrake is
on. Pull the carburettor choke control out to the stop, switch on the
ignition and press the starter switch button. When the engine has become
sufficiently warmed up, turn the choke control and allow the control
to spring back to the
half-out
position and turn to lock in this position.
After one or two minutes driving, as the engine warms up, it will be
possible to permit the control to return home without causing the engine
to run with undue hesitation. If the battery has been allowed to get
into a run-down condition, it is better to use the starting handle. When
the engine fails to start, do not keep the choke control out too long or the
sparking plugs will become wet with petrol and it will be necessary to
remove and dry them. When the car has been left standing for some
considerable time, the fuel level in the carburettor float chambers may
have become rather low, due to evaporation. The hand primer on the fuel
pump can be used under such circumstances, before the starter is operated,
(see page
29).
When starting in very cold conditions, the clutch pedal may be depressed
when operating the starter to relieve the motor of the considerable drag
in the gearbox.
Starting with Engine Warm or Hot
When restarting the engine while it is
still
hot the accelerator pedal should
be depressed to about one-third of its travel before pressing the starter
button, the choke control should not be used.
Warming
up
In order to minimise cylinder wear the engine should be warmed up
quickly when starting from cold in winter
;
the engine may be " idled
"
for a minute to let the oil circulate, but it should not be allowed to idle for
long periods, neither should the engine be raced up to high speeds.
An engine speed of approx.
1,500
r.p.m. may be regarded as a desirable
warming up speed.

SPORTS
CAR
DRIVING THE
CAR-The Engine
DRIVING
Gear Changing
For a smooth gear change into a synchronised gear (4th, 3rd & 2nd) the
movement should be slow and deliberate. The gear lever must always be
moved right home to secure full engagement. First and reverse gears are
not synchromesh, gear engagement being achieved by sliding the
respective gear into mesh. To avoid a noisy change do not engage
first gear with the car stationary and the engine revving at a speed greater
than 800
r.p.m., or when
travelling in access of
15
m.p.h.
Do not attempt to engage reverse gear whilst the car is travelling forward,
Desirable Speed Limits (Particularly in gears lower than top)
The engine is capable of" revving " very fast, yet the driver should avoid
continued
"
over-revving," which is most likely to occur in the lower gears.
We strongly recommend that in all gears the driver shall not drive
the car continuously at engine speeds above
4,500 r.p.m. How-
ever, during acceleration in the gears it is permissible to
attain
5,000 r.p.m. for short periods, which speed is indicated
by the red mark on the tachometer.
NEW ENGINES (see running adjustments)
During the early stages of a new vehicle's life, for at least the first 500 miles
(800
km.), the working surfaces of the engine will be bedding down. The
power and performance will improve only if during the running-in period
the vehicle is carefully driven at moderate speeds.
We recommend that the engine should be driven at speeds not exceeding 3,500
engine
r.p.m. during this period, and suggest that
"
running-in " should be
progressive. No harm is done if the engine is allowed to
"
rev " fairly fast
so long as it is thoroughly warm and provided it is not
pulling hard.
Do not
let the engine pull hard at low speeds, always select a lower gear.
GENERAL UPKEEP
REGULAR INSPECTION
Every
250
miles
(400
km.)
the oil level should be checked when the engine
is cold, and topped up if necessary. Withdraw dipstick
((F)
Fig.
3)
and wipe
clean, then insert and push fully home before withdrawing for reading.
Should the level be at the lower mark on the dipstick,
4
pints
(2.2
litres) of
oil
will
be required for topping up. The regular addition of oil not only
maintains the correct level, but also tends to keep up the quality of the
lubricant. Replenishment is via the cap
(D)
which does
NOT
require
unscrewing but may be lifted straight off.
Weekly,
Check
:
The water level in the radiator and if necessary replenish.
Use
clean rain water and keep the neck of the filler at least half full of
water.
Re-check after the engine has been warmed. The use of
hard water results in a deposit on the inner side of the cooling
surfaces, thus reducing efficiency.
Tyre pressures. The correct pressures are given on page
21.
It
is
usually a good plan to have the spare tyre inflated to a slightly higher
pressure than that recommended, as it is a simple matter to reduce
the pressure should the tyre be required for use.
The acid level in the battery at
(A)
and maintain
it
so that it is
just
level
with the top of the separators.
Overfilling may cause
the acid to spill and subsequently attack the surrounding
metal panels.
Use only distilled water when replenishing
(obtainable from the local chemist or garage).
Keep the filler plugs
screwed tight to prevent leakage of acid. Do not
overfill or the
acid
may splash out and do damage, and never use a naked light when
checking the acid level.

COOLING
SYSTEM
Filling
(see page 11).
Draining
For the purpose of draining, taps are provided in the bottom tank of the
radiator and at the rear of the cylinder block on the right-hand side. As
the cooling system is pressurised it will be necessary, when draining, to
remove the radiator
cap
(E),
Fig.
3.
If a heater is fitted, ensure that the cock is open before draining.
Anti-Freeze Mixtures
We recommend the use of Smith's " Bluecol," Duckham's Anti-freeze,
Esso Anti-freeze or Shell
"
Snowflake " Anti-freeze (inhibited Glycol
base compound) in order to protect the cooling system during frosty
weather and reduce corrosion to a minimum. The cooling system is
fitted with a thermostat and there is a risk of the radiator block freezing
while the engine is running during the warming up period when the
thermostat is shut, even though the car has been left in a warm garage
and water is not frozen at the start of the
run.
We recommend that you provide for the cooling system ample protection
against a sudden fall in temperature down to
0"
F.
(-18"
C.)
during
frosty weather by using
3
pints of anti-freeze.
In countries where sub-zero temperatures prevail, consult your Triumph
dealer regarding the quantity of anti-freeze required.
It is inadvisable to use anti-freeze for more than one season since
the inhibitor becomes exhausted and the components in contact
with the cooling water may corrode.
LUBRICATION
This
is
one of the most important subjects
in
connection with the upkeep of
a
car, and careful attention to the following instructions will be amply repaid by
the results obtained
For the recommended periods of lubrication, see the lubrication chart
folded inside the rear cover of this book.
The
correct lubricants to be
used are given on pages
51
and
52.
GENERAL UPKEEP-Lubrication
Draining
To drain the engine, gearbox and rear axle, remove the plug provided
beneath each unit. This process is assisted by opening the filler to allow
ingress of air and by draining when the oil is hot,
i.e.,
immediately after
a run.
ENGINE
Only first quality oils are recommended for use in the engine sump. These are
each of the correct viscosity and character to
afford complete
lubrication
protection.
Additives which dilute the oil or otherwise impair this protection
must not be used.
After many thousands of
miles
running the rate of oil
consumption
will increase. When the rate becomes higher than 1 gallon per
1,000 miles
(1
litre per 400 km.), it will be desirable to use the next heavier
grade of the brand of oil you normally employ.
Engine
Oil
Drain Period
The frequency of the drain period should be related to the driving
conditions to which the vehicle is subjected. A period of
3,000
miles
(5,000 km.) is recommended as the interval for average driving conditions
as defined below.
It
should be reduced for unfavourable conditions
and may
be
extended for definitely favourable conditions.
Favourable
Long distance journeys,
with
little or no engine idling, on well surfaced
roads, reasonably free from dust.
Average
Medium length journeys on well surfaced roads with a small
proportion
of stop/start operation.
Unfavourable
Any of the following
:
(a)
Frequent stop/start driving.
(b)
Operation during cold weather, especially when appreciable
engine idling is involved.
(c)
Where much driving is done under dusty conditions.
We have found the use of an upper cylinder lubricant to be an advantage,
particularly in new engines, and recommend the use of such
a
lubricant,
particularly
until
the engine is thoroughly
cc
run-in." The lubricant should
be mixed with the fuel in the proportions given on the container. Such
lubricants
may
be used with advantage throughout the life of the vehicle,
particularly during wintry weather.

GENERAL UPKEEP-Lubrication
Carburettors
Every 6,000 miles (10,000
km.)
unscrew the brass hexagon plug
in the top of each of the carburettors and top up with current
engine oil to the level of the
inner hollow shaft. Apply oil
also to the throttle linkages on
the engine, do not oil the bearings of the transverse rod attached to the scuttle as this will
seriously deteriorate the sealing
composition.
The
Oil Cleaner
The oil cleaner has been designed to filter the oil to a very
fine degree and the only attention it requires is to see that the
filtering cartridge
(B)
is removed and that a new replacement cartridge is fitted at periods
not exceeding 6,000 miles
(10,000
km.).
Later models
employ a
"
full-flow " cleaner,
and since a very
"fine"

cartridge is fitted it is important that this operation is carried out,
otherwise, as the filter becomes choked,
unfiltered oil will be passed to
the engine via the balance valve in
the cleaner. To renew the cartridge,
unscrew the securing
bolt and remove the container, the cartridge can
then be withdrawn. On some models it may be necessary to unclip and
swing the crankcase breather tube rearwards to provide sufficient room
for container removal.
Wipe out the container to remove foreign matter trapped by the filter,
using a non-fluffy cloth, and inspect afterwards to make certain that no
cloth fibres remain.
It may be desirable to discard the old container washer
(A),
replacing it
with a new one each time the cartridge is renewed. When re-assembling
the container, ensure that the washer is correctly positioned in the groove
in the filter body. Do not tighten the bolt
(C)
more than is necessary
to obtain an oil-tight joint.
Approximately one pint of oil will be lost due to the removal of the con-
tainer, and the sump should be topped up with new oil after assembly.
GENERAL UPKEEP-Lubrication
The container should not be disturbed until cartridge renewal is required
;
as the accumulated dirt on the outside of the container may fall inside
and thus be carried into the bearings when the engine is re-started.
Ignition Distributor
(see Fig.
5)
Every 6,000 miles (10,000 km.), the cam
(B)
should be smeared lightly
with engine oil.
A
pronounced squeak occurs when the cam is quite dry.
Withdraw the moulded rotor arm from the top of the spindle and apply a
few drops or
thin
machine oil around the edge of the screw
(A)
to
lubricate the cam bearings and distributor spindle.
At
the same time, place
a single drop of clean engine oil on the pivots

SPORTS
CAR
GENERAL UPKEEP-Lubrication
Dynamo and Starter
The dynamo front bearing is packed with grease before leaving the works,
and after a considerable mileage the dynamo should be removed for cleaning, adjustment and repacking of the bearing with grease. This
should
be done preferably by the nearest Triumph or Lucas Service Depot. Every
12,000 miles (20,000 km.) pour a few drops of engine oil through the hole
in the centre of the rear end cap. The hole
is sealed from dust with a
small rubber plug.
The Starter is fitted with special bearings which require no lubrication.
Air
Cleaners. Every 6,000 miles (10,000 km.) it is advisable to remove the
air cleaners and wash in petrol, particularly the gauzes, after which soak
the gauzes in oil and allow to drain before finally wiping over
and refitting.
It
is very important to refit the air cleaners in the correct manner. Ensure
that the holes immediately above the setscrew holes in the carburettor
are lined up with the similarly positioned holes in the cleaner.
Oil
Filler Cap. Every 6,000 miles (10,000 km.) remove and swill the cap
in fuel, dry off and re-fit.
GEARBOX
Every 6,000 miles (10,000 km.) the oil level should be checked and topped
up if necessary.
To check the oil level, remove the rubber plug from the gearbox domed
cover, thus exposing the
dipstick (see Fig.
7).
Withdraw dipstick and
wipe clean, then insert
stick
and push it fully
home before withdrawing
for
reading. The
correct level is to the top
mark. The dipstick orifice is also the gearbox oil
filler.
If
an overdrive is fitted,
see also page 42.
Every 12,000 miles
(20,000
km.)
the gear-
box should be drained
and
refilled with new oil.

REAR
AXLE
The hypoid bevel gears fitted in the rear axle require special lubricants to
ensure efficient operation and long life.
As these are special oils, it is advisable
to completely drain and replenish with new
"Hypoid" oil every 6,000
miles
(10,000
km.);
and in any event do not exceed a period
nf
12,000 miles
(20,000
km.).
16
GENERAL UPKEEP-Lubrication
It is advisable to have the oil level checked during this period, and especially
after the first 1,000 miles, and replenish if necessary to level with the bottom
of the threads in the filler orifice. Should a top-up be necessary, investigate
the cause of
oil
loss. The filler plug is accessible from underneath the
car,
being fitted to the rear axle cover (see arrow A Fig.
8).
Clean away mud
before unscrewing the filler plug to avoid grit
falling
into the axle.
BRAKE
AND
CLUTCH OPERATION
It is important that the filler cap on the combined hydraulic fluid reservoir,
integral with the master cylinders (see arrow BI or B2 Fig.
3,
page ll),
should be removed every 6,000 miles (10,000
km.),
the fluid level checked and
topped up
if
necessary. The reservoir should be filled to within one inch
(2.5
cm.) of the top, and never less than half
full
(see page 51 or 52 for the
correct fluid).
Later models with disc brakes have a circular reservoir which has an inner
chamber
;
this supplies the clutch operation mechanism. The correct fluid
level is to the top of this
inner chamber.
As
the cups in the master and all operating cylinders are pure rubber, it is
imperative to use only the recommended special fluid. Mineral oils would,
in
a very short time, distort and ruin them.
Clutch Shaft Bearings
The grease
gun
should be applied to the clutch shaft bearing grease nipples
(one at each side of the clutch housing) every 6,000 miles (10,000
km.).
One
shot only is sufficient. The nipples are accessible from underneath the
car.

Handbrake Cable Conduit
A
grease nipple is fitted in the conduit, as shown in the lubrication chart, to
which the grease gun should be applied every 6,000
miles (10,000 km.).
During the winter
months it is very important to keep the cable regularly
lubricated, as this prevents the entry of water which on cold nights will freeze,
thus locking the brake cable.
When lubricating the cable, grease is forced both ways and the gun should be
pumped until grease exudes at the end of the conduit.
Handbrake Compensator
Two grease nipples are provided on the compensator which is situated on
the rear axle casing (see arrow
B,
Fig.
8).
Front
ROAD
WHEEL HUBS
Recharging the hubs with grease on later models involves removing
the hubs, washing the bearings to remove all traces of the old grease
before liberally coating the rollers and races with new grease. This
should be carried out every 12,000 miles (20,000 km.). Where disc
brakes are fitted do not disturb the pipe unions but unbolt and move
the complete caliper, to
allow the hub and
disc to be removed, taking
care not to loose shims which may be fitted between the caliper and
the vertical link.
When replacing, ensure that the
inner race is tight against its shoulder.
Tighten the hub
nut until resistance is felt to hub rotation, then slacken
off
the nut by one flat of the hexagon and fit the split pin. This work
should
be preferably undertaken by your local Triumph agent who has
the necessary equipment for the task.
If
disc brakes are fitted
and the car is being used in competitions,
slacken off the hub nut one half flat and insert the split pin through one of
the two holes provided.
Rear
These bearings are lubricated via a nipple (see
arrow, Fig.

situated
facing downwards at the
rear of the brake backing
plate. Give five strokes

Greasing of these points should be carried out at least every 1,000 miles
(1,600 km.).
To lubricate the steering box, remove the rubber plug situated on the steering column and top up with oil to the level of the orifice. This should
be carried out every 6,000 miles (10,000
km.).
