Frequently asked questions

What is the +0.020 inch oversize piston assembly used for?
The +0.020 inch oversize piston assembly is a replacement piston for the 300Tdi 2.5L 4-cylinder turbo diesel. It's machined 0.020 inch larger than standard bore diameter, for engines whose cylinders have been rebored oversize during reconditioning. It restores correct piston-to-bore fit in a machined block.
How many pistons do I need for a rebuild?
This is supplied as a single piston assembly, so a full 300Tdi rebuild needs four to match the 4-cylinder engine. Order one per bore, and make sure every bore is machined to the same +0.020 inch oversize so the set is consistent across the engine.
How do I know if I need the +0.020 inch oversize piston?
You need the +0.020 inch oversize piston only if the cylinder bores have been machined 0.020 inch over standard. Confirm the actual oversize with your machinist or by measuring the rebored cylinders before ordering, since the wrong oversize gives incorrect piston clearance.
Is there an alternative part number for this piston?
Yes, this OEM 300Tdi +0.020 inch oversize piston is also cross-referenced as ERR241020. It fits the 300Tdi engine in the Defender, Discovery 1, and Range Rover Classic, so either code identifies the same oversize piston assembly.
