Rod Boring / Grinding RB1500
The Winona Van Norman RB1500 Rod Boring Machine is engineered for precision resizing of connecting rods, delivering the accuracy and consistency required in professional engine rebuilding operations. Designed to restore big-end bores to exact specifications, the RB1500 ensures proper alignment, roundness, and size after cap replacement or machining, helping eliminate bearing issues caused by out-of-round or misaligned rods.
Built for durability and repeatable performance, the RB1500 is especially well suited for large diesel and marine engine applications, where oversized connecting rods demand rigid construction and stable cutting performance. Its smooth, controlled boring action provides reliable results on heavy-duty components, supporting proper bearing crush, uniform oil clearance, and extended engine life—making the RB1500 an ideal solution for shops handling high-horsepower diesel and marine rod reconditioning.
