Series Land Rover
The Series Land Rover 2.25 litre Diesel Engine (3 bearing)
Owners of Series 1 and Series 2 Land Rovers fitted with 2 litre diesel engines complained of poor road performance due to lack of sufficient power. This prompted the development of the 2.25 litre diesel engine that was introduced with the Series IIA Land Rover in late 1961.
This Land Rover diesel engine was based on the 2.25 litre petrol block used in the Series II Land Rover and had the same 3 bearing format for the crankshaft and with the same cylinder bore and piston stroke. But a new inlet manifold helped to increase bottom end torque from 87lb/ft at 2,000rpm to 103lb/ft at 1800rpm. Better combustion chamber design helped to reduce engine noise. The cylinder blocks were painted Light Admiralty Grey.
All Land Rover Series 2a vehicles were fitted with this engine if the diesel option was orderd. It was even fitted to the 2a and 2b Forward Control Land Rover, though it was seriously underpowered for this application. The engine was only fitted in the Land Rover Forward Control from 1966 to 1972.
The Series 3 Land Rover had this engine fitted from the models inception in 1971 until 1980. The engine has a reputation for long service though it lacks power and economy in performance.
For a Series 3 Land Rover fitted with this engine you could expect to get a fuel consumption of 22mpg (7.8km/litre).
The cylinder block is made of cast iron and can be re-bored to 040in (1.0mm). If a greater re-bore is required it is recommended that cylinder liners be fitted after re-boring to restore the cylinder bore dimensions to original spec.
Later Series 2 and 2a Land Rovers had stronger inner valve springs and they were strengthened again for the Series 3 models.
