The Triumph TR3 profile: Still an entry level roadster?

The Triumph TR3 is your typical classic British roadster. No frills, no gimmicks – pure driving pleasure is paramount here. In our Triumph TR3 guide, you can find out what should be considered when buying this icon.

Three versions of the roadster were produced from 1955 to 1962, with the first generation hitting the road in September 1955. Production continued until 1957, during which 13,377 of this series were produced.

The Triumph TR3A was presented in 1957 and served primarily as a visual upgrade. In the factory, the “A” designation was never used, however this became natural afterwards and alludes to “America”, since most copies were exported to the USA. The Triumph TR3A was manufactured until 1962, during which 58,236 cars were completed. To date, the TR3A is considered the manufacturer’s most successful model alongside the TR6 and TR7. Parallel to the introduction of the Triumph TR4, the Triumph TR3B was also presented, which was specially designed for the American market.

Triumph TR3: the Facts

The Triumph TR3 is equipped with a 1991cc, four-cylinder, in-line engine that produced 95bhp. It’s an overhead valve design with a single chain-driven camshaft, and is fed by twin carburettors.

The four-speed all-synchro transmission was available with overdrive as a cost option. Power is then sent to the rear axle, which is equipped with hydraulically operated drum brakes. The front of the Triumph TR3 is fitted with Girling disc brakes. This car has an empty weight of under one ton (without driver), a wheelbase of 2248 mm and a top speed of around 108mph.

Triumph TR3’s bodywork and mechanicals

Today it is difficult to find a Triumph TR3 in its original condition. Most examples will have been professionally welded, repaired, or restored by now. The contact points at which the body is connected to the frame are particularly vulnerable to corrosion. You can see some by opening the bonnet and using a torch to inspect them. While under the bonnet, you can take a look at the battery box for any rust.

Externally, the B-pillars and rear wings should also be checked for rot. At the rear of the TR3, you should take a close look at the spare wheel compartment, which is also a notorious rust spot. As with most classic vehicles, the inner and outer sills should be checked carefully.

The Triumph TR3 is relatively simple and easy to maintain. Potential weak points on the vehicle include the rear crankshaft seals, which were original rope seals, though they can now be converted to modern rubber seals. The cylinder head can crack between the valves, which can’t be seen externally but might result in uneven running.

When test driving the car, make sure that the clutch sounds healthy when released at idle. Noises could suggest an issue with the intermediate bearing. If the gears pop out while accelerating and decelerating, you should prepare for a gearbox overhaul.

Conclusion

Spare parts for the Triumph TR3 are generally in good supply. However, exceptions, as always, prove the rule. While mechanical pieces are relatively easy to find, bodywork and instrumentation are more difficult to come by. The latter are hardly available anymore, here you usually have to find reconditioned parts. Many body panels are available in the form of reproductions, but their fit on such handmade cars can be tricky.

In terms of price, it is almost irrelevant whether you choose a Triumph TR3 or TR3A. For vehicles in moderate condition, the values start at around €12,000, while well-preserved examples are billed at up to €35,000.

It is fair to say that if you pay attention when buying, your dream of a classic British roadster can be attained with the TR3. The biggest problem is definitely rust, and so it is worth being preemptive with rust-prevention work if you have some change left over.
