Welcome to Dorman Diesels

For over a century, Dorman customers have repeatedly chosen Dorman products because they appreciate the blend of quality, reliability and total commitment to after-sales service that is synonymous with the Dorman name.

All manufacturers claim to support their products. The Dorman difference is our total commitment, wherever you are. Parts are regularly supplied worldwide for engines over 50 years old and we also hold extensive stocks of parts for older model Ruston engines, manufactured by Ruston & Hornsby Ltd. We hold an extensive range of genuine new and reconditioned Dorman Diesel engine parts for immediate delivery worldwide. Dorman Diesels’ spares facilities in Lincoln provides a modern parts warehousing facility, where thousands of line items are stocked and over half a million individual components held.

The parts warehouse is fully mechanised and computerised and linked to a modern computer-backed order processing system that co-ordinates the packing and despatch departments to ensure a speedy and efficient service. When an engine does break down, Dorman Diesels are committed to ensuring an engine is operational with minimum delay, achieving urgent despatch of replacement parts by the fastest means possible.

All new spare parts supplied are supported with a full 12 months warranty. Inspection to Lloyds certification or other inspection authorities can be undertaken at our works as required, providing independent witness tests and inspection.

Dorman diesels is a part of the Diesel and Marine Group, supporting the marine, offshore, chemical, power generation, water, and railway industries.
