Land Rover Part Number: LR004436 - Piston with Pin and Rings - Standard Grade A
LR004436 is a piston with pin and rings assembly for the 2.4L Duratorq-TDCi 'Puma' diesel engine. Fitted to Defender L316 applications, the assembly sits in the cylinder bore and transmits combustion forces through the connecting rod to the crankshaft; Grade A indicates standard bore dimensions and is selected where standard cylinder diameters and clearances apply.
This piston, pin and rings set forms the moving seal between the combustion chamber and the crankcase. The piston crown accepts combustion pressure, the piston rings control the oil film and seal combustion gases at the cylinder wall, and the gudgeon (wrist) pin links the piston to the connecting rod allowing the required rocking motion during the stroke. In a Defender fitted with the 2.4 Puma diesel, fitting the correct piston and ring set is essential to restore compression and manage oil consumption within expected limits. Use the compatibility data below to confirm fitment against your V.I.N.
