This is a 13/40 (3.076:1) ratio crown wheel and pinion. This was the standard ratio in the Bentley Continental Sports Saloon, it provides just under an 18% uplift in gearing over a standard Bentley MKVI axle, and nearly 10% over the last Bentley R type production axle. Delivering approximately 55mph at 2000 rpm / 69mph at 2500 rpm with standard 6.50 x 16 tyres, it is nicely geared without being over geared and is suitable for the enjoyment of both short and long distance touring in MkVI, R Type and RR Silver Dawn models.
Although we are offering the crown wheel and pinion we strongly advise the purchase of one of our reconditioned differentials. This is because they are notoriously difficult to successfully overhaul without the correct specialist tools and parts. Please speak to us before placing your order.
Ideally, where possible, we would recommend that you ship us your old axle (differential and half shafts) to be overhauled. We can then assess the condition and advise accordingly.
We were extremely privileged to be offered the chance to continue Norman Geeson's axle building business, Crewe Classix Six, when he retired. More details can be found here.
