Synchro RingTriumph gearboxes originally used rings made of “Iron Bronze”, a sintered metal containing copper and iron predominately. This provided synchronising (of sorts) and long life. The brass compounds used these days offer improved synchronising, though nowhere near that of modern gearboxes. In reality the actual ring size and friction area are inadequate. The working life of the ring is indicated externally by the gap between the dog teeth on the ring and the gear, from the 0.045" (new) down to 0.025" (worn) range. It is not unknown for less than scrupulous rebuilders to skim off the back face to give the appearance of a new ring. The problem here is that this ignores the relationship between the areas shown, A and B, to give the internals of the box their correct clearance.

The brass second gear bush used to 1973 often breaks where its flange joins the cylindrical body. This breakage leads to excessive end float in the second and third gears, which in turn causes severe and rapid mechanical failure. A two piece steel bush and thrust washer is offered as an uprated replacement for the one piece brass item. The two piece steel bush set can not be used to replace the steel top hat shaped bush of the post 1973 gearboxes.

Alternative.
The shell type countershaft bearing, part no. 126862, fitted to early Triumph gearboxes, was later changed (approx. 1961) to the open cage type bearing. This improved the durability of the countershaft bearings and allowed a more efficient high speed bearing arrangement. The earlier shell type bearings do however appear in the later gearboxes as they proved to be a good alternative to salvage countershaft gears with slightly pitted bearing surfaces. When fitting new countershafts and gears, the open cage bearings should always be used.
The 126862 shell type bearing is identifiable by an external solid steel shell or case. It is a press fit in the countershaft gear. The 150339 open cage bearing is loose fitted in the counter gear and is retained by a spacer and circlip on early installations. If the countershaft gear has a circlip groove, it must be fitted with a circlip to retain the bearing.

Most TR owners know that the Stag and Police spec saloon gearboxes were uprated by modifications to the weak zones of the laygear and shaft. The rear end of the shaft and gearbox became 'metric', so this conversion would be quite difficult. These uprated laygears come complete with 3 bearings and fittings. The twin bearing fitted to the rear end, each have twice the load capacity of the original (150339). They fit the standard gearbox and layshaft, so no modifications are required. If your gearbox has suffered such a failure, you will appreciate this as a fit and forget solution.

Includes bearings and circlips.
