Land Rover Part Number: RTC418820 - Piston Assembly 0.020 in Oversize - 2.25 Petrol
RTC418820 is a piston assembly 0.020 in oversize for 2.25 petrol engines. The assembly includes piston, piston rings, gudgeon pin and circlip for installation in a 2.25-litre petrol engine cylinder. The piston converts combustion pressure into linear force transmitted to the connecting rod and crankshaft; the piston rings seal between piston and cylinder wall to control compression and oil consumption, while the gudgeon pin joins the piston to the small end of the connecting rod and the circlip retains the pin. This assembly is intended for 2.25 petrol engine applications in Series and Defender models where a 0.020 in oversize piston is required following wear or re-bore.
