Mathway gearboxes are exceptionally reliable and often provide decades of service. Many are fitted to Rolls-Royce oil engines, including the C6TFLM, C6SFLM, C8TFLM and DV8TCM. They have also been used with the Cummins NT-380-M, V8N-300M and NHP.56M, Klockner-Humboldt-Deutz AG engine, General Motors 8V-71 engine, the National Oil Engine and the Bristol Proteus marine engine.

The photos on this page show two Mathway RRD8 gearboxes overhauled with support from Parsons Mathway Marine.
