Cosworth DFV Fuel Pump Drive Couplings Remanufactured

We were recently asked to supply a major DFV engine rebuilder with new DA3466 fuel pump drive coupling adaptors. It might look like an inconsequential part, but without it the fuel pump can’t turn, meaning no fuel pressure.

These adaptors hadn’t been manufactured for a number of years, so we retrieved the drawing from Cosworth’s archive and then worked with one of Cosworth’s approved suppliers to remanufacture new batches. Working with the machinist, we were able to specify the best grade of Nylatron available, and ensure that it was machined to same exacting tolerances as per the original parts.
