Land Rover Part Number: RTC599320 - Piston 0.020in Oversize - 2.5 Diesel Turbo
RTC599320 is a Piston 0.020in Oversize for the 2.5 Diesel Turbo. Supplied as a complete piston assembly - piston, rings, gudgeon pin and circlip - it fits the 2.5 Diesel Turbo (19J) engine used in Defender models. The piston transfers combustion pressure into reciprocating motion via the gudgeon pin to the connecting rod and crankshaft; compression and oil rings fitted to the piston control combustion sealing and oil scraping at the cylinder wall. The 0.020in oversize dimension is intended for cylinders machined to an oversize bore after wear or damage; confirm the bore size recorded at overhaul before assembly to ensure correct piston-to-wall clearance and running geometry.
