The Series III Land Rover 2.25 litre Diesel Engine (5 bearing)

In the same way that the 2.25 litre petrol engine was upgraded to a 5 bearing crankshaft, so it was with the 2.25litre diesel.
The 5 bearing Land Rover diesel engine was fitted to Series III Land Rovers from 1980 to 1984. Starting with the 88in wheelbase, it was then fitted a few months later to the Series III 109in. The first of the Land Rover 110's also have this engine.

As with the equivalent petrol model, Land Rover marketed the engine with the 2.3litre specification to distinguish it from the earlier 3 bearing model, though it actually still had the 2286cc capacity as before.
For a Series 3 Land Rover fitted with this engine you could expect to get a fuel consumption of 22mpg (7.8km/litre). There is a known history of the cylinder head being prone to cracking but this is in common with various other diesel engines due to the high cylinder compressions involved. .

Engine specs:

swept engine volume: 2286 cc
cylinder bore: 90.47mm
piston stroke: 88.9mm
compression ratio: 23:1
power: 60bhp at 4000 rpm
torque: 103 ft lb at 1800rpm
Cast iron, water cooled, in-line four cylinder with overhead valves
Fuel injectors: CAV Pintaux
Lubrication: pressure fed wet sump

Engine numbers for the Series III Land Rover installations begin in the series 366-00001A
