Frequently asked questions

What is the RTC644240 piston assembly?
The RTC644240 is a piston assembly at +0.040 inch oversize for the 2.5 litre naturally aspirated diesel engine. It typically comes as the piston with rings and gudgeon pin for a reground cylinder bore. This is the oversize service size.
What does +0.040in oversize mean and when do I need it?
The +0.040 inch oversize means the piston is machined larger than standard to suit a cylinder bore that's been rebored 0.040 inch. You need this size only if your engine block has been machined to that oversize. Check the rebuild spec before ordering.
Which engine does this piston fit?
This piston assembly fits the 2.5 litre four cylinder naturally aspirated diesel used in the Land Rover Defender from 1987 to 2006. It's specific to the NA diesel, so confirm you don't have the turbo diesel or Td5 before ordering.
How many pistons do I need for the engine?
A four cylinder engine typically needs four pistons for a full rebuild, so you'll usually order this in a set of four all at the same oversize. Mixing sizes across cylinders isn't done. Check each bore has been machined to +0.040 inch.
