The Perkins 400 Series is a range of compact diesel engines available in 2, 3, and 4-cylinder configurations, with power outputs from 8.2 to 60 kW.
Widely used in agricultural machinery, construction equipment, and industrial generators, the 400 Series is known for its durability, fuel efficiency, and ease of servicing.
The Perkins 400 Series is a family of compact diesel engines designed for agricultural, industrial, and construction applications.
Introduced by Perkins Engines (now part of Caterpillar Inc.), the series has become one of the most widely used small diesel engine ranges worldwide.
The 400 Series is available in 2, 3, and 4-cylinder configurations, with displacements ranging from 0.5 to 2.2 litres and power outputs from 8.2 to 60 kW (11 to 80 hp).
Key variants include the 400A, 400D, and 400F subfamilies, with common model numbers such as the 403D-11, 404D-22, and 404F-22.
The 400 Series is known for several characteristics that have contributed to its widespread adoption.
Compact dimensions. The engine's small footprint makes it suitable for machinery where space is limited, including mini excavators, compact tractors, and skid steer loaders.
Fuel efficiency. The mechanical fuel injection system (on earlier models) and common rail electronic injection (on later F-series variants) are designed to optimise fuel consumption across varying load conditions.
Serviceability. Parts availability remains strong through Perkins dealers and independent suppliers. The engine's straightforward design means many agricultural and plant engineers are familiar with its service requirements.
Durability. The 400 Series is engineered for extended service intervals and reliable operation in demanding environments, including dusty agricultural settings and continuous-run generator applications.

Perkins 400 Series engines are found in equipment from manufacturers including JCB, Caterpillar, Massey Ferguson, Genie, and Wacker Neuson. Typical applications include:
For operators running existing 400 Series-powered machinery, the engine's continued parts availability and strong service network make it a sensible platform to maintain.
Replacement and remanufactured engines are readily available, offering a cost-effective alternative to new units while retaining the proven reliability of the original design.
The series also holds its value well in the used equipment market, as buyers recognise the Perkins name and the relative ease of sourcing parts and service support across the UK and internationally.
Regular servicing is essential to maximise engine life and performance. This includes oil and filter changes at recommended intervals, fuel system maintenance, and cooling system checks.
Genuine Perkins parts or quality aftermarket equivalents help ensure consistent performance and avoid premature wear.
When a full engine replacement is required, remanufactured Perkins 400 Series engines offer a balance of reliability and value, rebuilt to original specifications using new or reconditioned components.
The engine block is bored back to standard with new liners fitted, cylinder head re-manufactured with valve seats re-cut and new valves fitted if necessary and crankshaft ground.
The fuel injection equipment is remanufactured and a reman turbo is also fitted (if applicable).
The engines are re-assembled in our clean workshop with new pistons and rings, bearings, oil pump, water pump, and all new gaskets fitted with all other components inspected and changed if necessary.
The engine is then dynamometer tested and painted ready for delivery.
We are members of the Federation of Engine Re-manufacturers.
Therefore our remanufactured engines are required to meet a certain standard under BSI AU 257:2002, set by British Standard Automobile Series code of practice.
