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.

1st speed gear 152803), be used for all uprated/modified engine/competition boxes.

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.
