One of Kingsbury Racing Shop’s engine builders expertly rebuilds a sub-assembly of a Bentley six-cylinder ‘three-throw’ overhead camshaft drive system. Designed by W.O. Bentley, and patented by the company, the system uses a trio of rods to drive the camshaft.
Precise set-up of the end float and backlash is critical to achieve the silent running W.O. intended with this design. It’s extremely quiet operation is the reason Bentley preferred this mechanism to the more common belt- or chain-driven systems.
Thanks to our ongoing expansion, Kingsbury’s engine-building capacity is increasing and we’re ready to discuss new clients’ requirements.
