Land Rover Part Number: FTC4850 - LT230 Mainshaft Gear - 38 Tooth - 1.2:1
FTC4850 is an LT230 mainshaft gear with 38 teeth and a 1.2:1 ratio. Fitted as the driven gear on the LT230 mainshaft, it transmits torque through the transfer box and establishes the 1.2:1 drive relationship between the mainshaft and the output elements. Correct tooth form and pitch are essential for quiet running and even load distribution; gears showing pitting, chipped teeth or abnormal wear should be replaced during a transfer box overhaul to restore correct mesh and ratio.
