  • Injector Nozzles

    For a diesel engine to function correctly, the injector has to produce atomised fuel at a set pressure and a specific time in the power cycle. To achieve this, the injector nozzle might need to be replaced at some stage if the engine is not performing as economically as it used to or if nozzle replacement is an intrinsic part of a car’s service plan.

    If nozzle replacement is required, like-for-like is a must, otherwise an injector fitted with the wrong spray angle nozzle may cause engine malfunction. .

    At Darwen Diesels we stock a wide range of nozzles including genuine and replacement nozzles for Bosch, CAV (Delphi), Simms, Bryce, Zexel, Diesel Kiki, Yanmar, Nippon Denso, Leyland, Stanadyne, Gardner etc.

  • Gasket / Seal Kits

    At Darwen Diesels, we stock Bosch rotary VA/VE flange gaskets and repair kits, Perkins fuel line seals and Perkins injector body seals. This is just a very small selection of our wide range of stock items.

    We also stock overhaul kits for older style applications such as CAV, Bosch rotary and inline, Simms Minimec and Majormec. We also keep Denso and Zexel pump repair kits.. These gaskets/seal kits contain flange gaskets, O rings, washers, etc. In fact, everything required to repair specific units.

    We also keep a range of lift pump repair kits and individual components such as diaphragms, and one-way valves.

    We also do a repair kit for the Bryce single cylinder aluminium pump which is used by Petter/Lister for static engines such as water pumps and concrete mixers.

    Please contact us for more information on your specific needs.

  • Miscellaneous

    At Darwen Diesels we also stock a range of items that are not in any of the other categories, for example Denso, Stanadyne, Yanmar, Dipaco parts, glow plugs, Ford D series and Leyland injector inlet seals, Ford D series flange O rings, grommets, flange gaskets, Thermo couplings etc. These tend to be parts for older and perhaps more obscure vehicles for which demand is limited but consistent. For these particular parts, it would be worthwhile calling us directly to discuss your specific requirements.

  • Drive Shaft Seals

    Drive shaft Oil seals are generally used for dealing lubricating oil, diesel, grease and any other fluids, powders, gasses or granular solids. For trouble -free operation and optimal service life, drive shaft seals must seal and survive. Both proper design and material choice are critical if they are to seal against penetrating dust and dirt, and to prevent any liquids etc escaping. Good oil seal design is therefore, a balance between optimum running properties of the material, lip design and integral garter spring.

    Drive shaft seals come in many shapes and sizes with single lip, double lip and wiper lip, depending on where it is fitted in the engine. The sealing capacity of an oil seal depends on the pressure exerted by the sealing lip on the shaft. The degree of pressure is directly related to the pre-stress and dimensional tolerances of the seal and the shaft.

    Drive shaft seals now tend to be made out of Viton (Dupont Trademark) with a temperature resistance range from -40°C to approximately 200°C
