Cylinder Blocks

Cylinder Blocks

We specialize in aftermarket - new and re-manufactured diesel engine cylinder blocks. A cylinder block is the structure which contains the cylinder, plus any cylinder sleeves and coolant passages. In the earliest decades of internal combustion engine development, cylinders were usually cast individually, so cylinder blocks were usually produced individually for each cylinder.

Diesel Cast Welding produces new and remanufactured cylinder heads, engine blocks, connecting rods, crankshafts and also can repair these broken parts! Diesel Cast started remanufacturing cores and repairing diesel cast parts 84 years ago in 1936. Our work has always been produced to OEM standards and warranties. Diesel Cast Welding continuously receives calls for a wide variety of diesel engines. There are over 250 diesel engine manufacturers with over 25,000 engine models, series, castings and other variations. Also, since diesel engines last for twenty to thirty years many models are not supported by the OEM manufacturer. Because of this extraordinary array, we can only stock about two thousand of the most popular models. However, Diesel Cast Welding can also repair all of these items for customers at half the cost of a new OEM item. And all of these products are produced at OEM standards and warranties.
