The Perkins 1000 Series and Phaser are closely related engine families introduced in 1986 to replace the 4.236 and 6.354 ranges.
The 1000 Series was developed for agricultural and industrial use, while the Phaser variant was designed for automotive and commercial vehicle applications. Both share the same fundamental architecture, with a 100mm bore and 127mm stroke.
The early production engines, often referred to as "flat top" variants, feature a flat-top piston design with the Quadram combustion chamber in the cylinder head. These engines are identified by model codes AA through AH (4-cylinder) and YA through YE (6-cylinder).
The 4-cylinder 1004 models have a displacement of approximately 4 litres, while the 6-cylinder 1006 models displace approximately 6 litres.
Power outputs across the range span from 87 to 180 bhp, with naturally aspirated, turbocharged, and turbocharged/intercooled variants available to suit different performance requirements.
The 1000 Series represented a significant step forward from its predecessors, offering several improvements.
Metric design. Unlike the 4.236 and 6.354 which were designed using imperial measurements, the 1000 Series was built to metric specifications, making servicing more straightforward with standard tooling.
Reduced emissions and noise. The Quadram combustion chamber design improved fuel efficiency by around 8% compared to industry standards at the time, while also reducing exhaust emissions and engine noise.
Flexible configuration. The engine was offered with multiple options for filter positions, fan heights, and ancillary mounting points, allowing equipment manufacturers to integrate it without compromising their machine designs.
Durability. Built for demanding agricultural and construction environments, the 1000 Series became known for reliable operation over extended service intervals.
The early 1000 Series engines use a two-letter code system to identify the variant:
4-cylinder (1004) models:
6-cylinder (1006) models:
The Perkins 1000 Series and Phaser engines powered equipment from manufacturers including JCB, Massey Ferguson, Seddon Atkinson, Dennis, and Metro-Cammell. Typical applications include:
Despite production of the final 1006 variant ceasing in 2014, the early flat top engines remain widely used in working machinery across the UK and beyond. Parts availability is strong, and the straightforward mechanical design means many engineers are experienced in servicing and overhauling these engines.
For operators maintaining existing equipment, a remanufactured Phaser or 1000 Series engine offers a cost-effective solution that retains the proven reliability of the original design.
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 Phaser and 1000 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.
