The answer I gave was correct, but as always, the devil is in the details. Careful attention must be paid to matching the pushrod tubes when mating different year parts. However, the tappet guide blocks, pushrod tubes and cylinder heads MUST be matched completely.

This is because of deeper machining at the upper pushrod tube position to any earlier series of tappet guide blocs and pushrod tubes. If a or later cylinder head is used, same year pushrod tubes and tappet guide blocs must also be used. All engines must have a thin gasket under the pushrod seal cup at the bottom of the pushrod tube. Rocker boxes interchange to all s from through All cylinders have 26 TPI Whitworth threads.

The following comes from my many years of research into the old Triumph Works at Coventry, not from any documentation, for none survived from the air raid attack on the night of November 14th From the time when Triumph started producing machines with their own engines for the engine would be date stamped with the date of machine assembly. Engines, frames, and later, gearboxes were made in different parts of the Works.

The frames and gearboxes were stamped with a sequential number which identified their type, while engines were assembled but un-numbered. From their different shops workshops the engines, frames and gearboxes, along with other items, were transferred to a central stores from where they would be collected as ‘kits of parts’ for putting together in the Assembly Shop. As the storeman would not issue items in direct numerical sequence, and subsequently move the following items along the shelf, there was no direct correlation between numbers at any particular time.

Very often the most recent items received would be placed on the closest shelves or hangers, and it would be the closest items which would be selected when the apprentice lad with his barrow turned up for the collection of more ‘kits’ for the assembly shop. So often an earlier frame or gearbox number might appear with a later numbered engine; and occasionally a very early number could appear with a much later engine, simply because it had languished down the far end of the stores.

Triumph identification of the assembly sequence of each model came from the engine number, for this was stamped on completion of the assembly.

Here are some of his observations:. A central storage for these various parts was The Stores. The storeman would stack those parts on shelves and probably hang the frames up. The frames and gearboxes were serial number stamped when they were made but the storeman would not move items along the shelves and racks to keep them in number sequence.

Engines MAY have been number stamped, but I think not as these numbers certainly went into frames in a sequence. Also into stores would have gone other parts made elsewhere, such as magnetos, control levers and fuel tank caps. Another lad probably would have been an older and more experienced apprentice who knew which items would be needed would transfer parts from the stores to the Assembly Shop.
