CAR IDENTIFICATION

When ordering parts, it is essential that you identify your car exactly, by model year and serial number. Since many part changes were made during model years, the commission number, engine number and body number provide the only positive identification. Quite often a car's title will not show the correct model year. Before ordering parts, please record the applicable numbers from your car. Using these numbers is the best way to ensure that you order and receive the correct parts. Wherever possible, we have listed part applications by commission number (e), body number (b) or gearbox (g). For more information on these numbers and years, see the production data below.

*A Note on TR3B's

The TR3B was a very interesting and rare car. Declining sales in the late 50's and early 60's of the TR3 series had led Triumph to carry out a major re-design of the car, which became known as the TR4. It was based on the TR3 running gear but had a Michelotti designed body with wind-up windows and other features designed to improve comfort. The reaction to the TR4 in America was, initially, less than favourable and there was a minor panic back in Coventry where the feeling existed that a mistake had been made in introducing the TR4, and, it was felt essential that the TR3 was 're-introduced'. The car that was re-introduced was the TR3B and in its most basic form the same as the TR3A. There were two series of commission numbers (TSF and TCF), we believe the TSF series was for the 1991cc (83mm) engine and the TCF series for the 2138cc (86mm) engine. Both vehicles were fitted with the later TR4 all-synchromesh gearbox. These are the only distinguishing features that all experts appear to agree on. Unless otherwise specified in the text, all details of the TR3B can be considered to be the same as the post T60001 TR3A.

Location of Serial Numbers

TR2-3B Commission Number

This number is stamped on a plate which is riveted to the righthand bulkhead panel.

TR4-4A Commission Number

This number is stamped on a plate which is riveted to the lefthand bulkhead panel.

TR2-4A Gearbox Number

This number is stamped on the lefthand side of the gearbox casing.

TR2-4A Engine Number

The engine number is stamped on the lefthand side of the cylinder block.

Supersession of Parts

For those of you in possession of original Triumph parts books you may have information which conflicts with that given in the original book. This is usually because the part has been 'superseded' because of some change in specification. For example XKC510 is the lefthand A-post. It used to be 813100 (and the righthand is still 813101), but when the TR6 USA specification cars had an audible buzzer fitted to advise owners that they had opened their door and left the keys in the ignition, it required an extra hole in the A-post to sense the door being opened. Hence 813100 with one hole for a courtesy light becomes XKC510 with two holes. There are many other examples where our Research & Development Department staff find old Austin/Morris saloon car parts that 'will do' to replace 'no longer available' TR parts. These often utilise different part numbers to those shown in the original Triumph parts book.

Narrow Fan Belt Conversion (Damped) There will be many who will wish to seize the opportunity to fit a narrow belt conversion at this time, and ensure the life of that precious crankshaft, with the harmonic damper included in this kit. Every modern car is fitted with a damper, so this must be key to engine harmonic stress elimination within older engines. This kit includes Harmonic Damper (crank), Spacer, Bolt, washer, (alternator) Pulley (water pump) Pulley (alloy) & Fan Belt. See electrical section for 'alternator conversion' using this narrow belt conversion.
NI	TT1132	NARROW BELT KIT, DAMPED, 3/8"	1		CHF 240.45
The damped pulley conversion (TT1132) requires the use of an electric fan and removal of the fan & fan hub extension - which is obviously the best way to go. For those who are determined to retain the original (rather agricultural) fan arrangement and fit an alternator, we can supply a crankshaft pulley (107252A) which does allow this if used in conjunction with the water pump pulley (105537A) and the alternator pulley (12G1054) required for your application.

Lastly (unless you are retaining your old wide belt pulley), you now need to choose the pulley to enable a perfect match of alternator performance to your TR's use. Only one of the 4 listed is essential, though you might wish to select more, for instance if the car is used for occasional competition use. All these are for narrow belts. If you are retaining the wide belt, ignore this list. As the wide belt stretches, it may be necessary to re-install the "old" adjustment link to obtain sufficient adjustment.
