Taper Roller Bearing – shaft bearing for the R380 five-speed manual gearbox.

A taper roller bearing carries both radial load and axial thrust, locating and supporting a rotating shaft within the gearbox at the countershaft / centre-plate position. The tapered rollers run between hardened inner and outer races, and correct pre-load on assembly is essential to bearing life and quiet running.

Replace together with its matching race and check shaft end-float on reassembly.
