Product Description
Bearing - Shell Type - 126862
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.
