O-Ring for the high-pressure diesel fuel injection pump.

The ring seals the joint between the pump body and its mounting face on the engine, preventing leakage where the pump is clamped into position.

This is a single-use elastomeric seal. Once it has been compressed and heat-cycled in service it takes a permanent set and will not seal reliably again, so it should be renewed every time the pump is removed or refitted rather than transferred to the replacement.

Applies to the 2.0L AJ200, 2.0L AJ20D4 / AJ21D4 and 3.0L AJ20D6 diesel engines.

Seat the ring square in its groove and avoid stretching or twisting it during assembly, and take care not to nick it against the pump spigot as the pump is drawn into place.

Frequently asked questions

What is the LR139238 O-ring used for?
The LR139238 is a sealing O-ring for the high-pressure diesel injection pump. It seals the pump against fuel and pressure leaks on the 2.0 AJ200, 2.0 AJ20D4/AJ21D4, and 3.0 AJ20D6 diesel engines. It's an OEM Elring seal.
Which engines and models use the LR139238 O-ring?
The LR139238 fits the 2.0 and 3.0 Ingenium diesel engines across the current range, including the New Defender L663, Discovery 5, Discovery Sport, Range Rover L405 and L460, Range Rover Sport L494 and L461, Evoque L538 and L551, and Velar L560. Confirm your engine before ordering.
Should the LR139238 O-ring be reused or replaced?
The LR139238 O-ring is typically a single-use seal. Once the injection pump joint has been disturbed, fit a new O-ring rather than reusing the old one, as a reused seal can weep fuel under high pressure. Replace it whenever the pump is removed.
How many LR139238 O-rings are needed for the job?
Usually one LR139238 O-ring is needed per injection pump seal, but check how many sealing points your pump job disturbs. Ordering a spare is common practice, since a diesel fuel seal is cheap next to the risk of a leak.
