Custom Parts

Here at MPS it is commonplace for us to overhaul an engine where many, if not all, spare parts are in short supply so if you have been searching for a part and just cant get one, then contact us. We carry a large amount of spares for Gardner, Kromhout, Lister and Samofa but if we dont have what you need we are able to offer a custom parts service for part which otherwise are unable to be found.

Either from a sample part or drawing we are able to reverse engineer a part and produce new items to replace it. So if you can't find a gasket or unable to source a replacement manifold MPS can help.

    So your engine is running fine but there are some things about it that don't fit with how you use it, or how it currently is makes it hard work to operate then here at MPS we can help.

    Many of the engines we deal with come from an era where things like manual temperature control, Hand Starting and mechanical gearboxes are commonplace. However in modern times an engine where you check the oil and water and press start is what people are used to so here at MPS we can offer a number of modifications to modernise your engine to ease it's use or to reduce the daily maintenance.

    Some of the Modifications we offer.

    • Electric start conversion

    • Adaption components for alternator fitment

    • Gearbox / Hydraulic drive adaption

    • Lister JP conversion to oil fed valve rockers (JK Spec)

    • Manual to automatic temperature control conversion

    • Application adaption (Marine, Rail, Power Generation, Automotive)
