Piston in 0.25mm oversize for the Ingenium AJ200D / 204DTD 2.0L 4-cylinder diesel engine.

This is an oversize piston, intended for a cylinder block whose bores have been machined 0.25mm above nominal during a rebuild. It is not a standard-size replacement. Four are required to rebuild one engine.

The piston runs in the cylinder bore and transfers combustion pressure through the gudgeon pin to the connecting rod and crankshaft.

Frequently asked questions

What is the GA3425 piston used for?
GA3425 is a 0.25mm oversize piston for the Ingenium AJ200D (204DTD) 2.0L diesel engine, intended for a cylinder block whose bores have been machined 0.25mm above nominal during a rebuild. It transfers combustion pressure through the gudgeon pin to the connecting rod and crankshaft.
How many GA3425 pistons are needed to rebuild a 204DTD engine?
Four GA3425 pistons are required to rebuild one 204DTD engine, matching the four-cylinder layout. This is not a standard-size replacement, so all four bores must be machined to the same 0.25mm oversize before fitting.
What's the difference between GA3425 and GA3424?
GA3425 is the 0.25mm oversize piston, for use only after the block has been re-bored. If your bores are still standard size, GA3424 is the correct piston instead. Confirm the actual bore measurement from your machinist before ordering either.
