Land Rover Part Number: TZZ100200 - 31.75 X 62.0MM Taper Roller Bearing - Layshaft R380
TZZ100200 is a 31.75 x 62.0mm taper roller bearing for the layshaft (countershaft) of the R380 five-speed manual transmission. Fitted to the layshaft/countershaft of the R380 manual gearbox, it carries both radial and axial loads and controls end-play to keep the layshaft aligned with the gears and synchronisers. Worn rollers or raceways increase clearance and commonly present as whining, rough gear selection or increased gearbox backlash; replacement restores the designed running clearances and roller contact profile within the layshaft assembly.

Frequently Asked Questions
TZZ100200 supports the layshaft (countershaft) inside the R380 five-speed manual gearbox by carrying both radial and axial loads and resisting end-play from gear forces. Excessive wear to the rollers or raceways increases clearance and typically causes whining, rough gear selection or increased backlash. The bearing should be replaced to restore correct roller contact and layshaft alignment when these symptoms are present or during a gearbox overhaul.
