Land Rover Part Number: FRC4714 - Manual Transmission Mainshaft
FRC4714 is a manual transmission mainshaft used in the 5-speed manual gearbox fitted to 3.5L V8 Defender models. Fitted within the gearbox, the mainshaft carries the selected gear clusters, locates the gear sets, supports bearing loads and transmits rotational torque through the gearbox to the output pinion and final drive. Correct mainshaft condition is vital for reliable gear engagement and consistent ratios; wear to splines, journals or shoulders can produce backlash, slippage or increased bearing stress. The assembly interfaces directly with the pinion and its bearings and must be installed with the correct end-float and bearing preload as specified in factory service data.
