Welcome to Welham Group
Good old fashioned engineering since 1947
Welhams started in business just after the end of the second world war and we have always been proud of our engine reconditioning skills.
We can rebore cylinder blocks, recondition heads and regrind crankshafts as well as complete engine rebuilds.
We are members of the Federation of Engine Re-Manufacturers which ensures that all our work is carried out to a high professional standard.
Our Services
In addition to the work we do on the vintage diesel side, we offer the same services for common rail pumps and injectors all the way up to Euro6 standards.
Welham Diesel, established in 1964 as an offshoot of Welham Motor Company, specialises in servicing and refurbishing fuel pumps and injectors for agricultural machinery.
Despite their age, our crankshaft regrinding machines are still regarded as some of the best.
