Nissan LD28
2.8 L · inline-6 · naturally aspirated · diesel · 1981–present
Also known as: ld28, ld20, ld, nissan diesel six, 2.8 diesel maxima
Nissan's 2.8 diesel straight-six — the LD28 — in the 910 and U11 Maxima, and one of very few diesel sixes ever sold in a mid-size saloon.
It is the diesel relative of the L-series petrol six and shares its architecture, which is the route into material about it: the L-series is famous and thoroughly documented, and much of the bottom end is common.
⚑ Its enduring reputation is as a donor. The LD28 crankshaft is forged and fits the petrol L28, and building a stronger engine that way is common enough that most surviving material discusses the crank rather than the engine. A search will return engine-building content where a repair question was asked.
It is belt-driven and entirely mechanical — an injection pump, glow plugs and compression, with nothing to interrogate.
The RD28 that replaced it is a different engine with its own page here, and the two are frequently conflated because both are Nissan diesel sixes.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
