Crank Drive Sprocket keyed for 2.0L/2.3L/2.5L Duratec
We have manufactured a new sprocket that includes the original cam chain drive and oil pump drive gears, we have also machined a 3mm wide keyway for positive location to the crankshaft. The standard item relies on friction to hold it’s location, which can cause issues in motorsport use. We produce these in large batches which means we have managed to keep the price of the component affordable and yet very high quality.
The standard crank assembly on the Duratec relies on a centre crank bolt being tightened sufficiently to hold the front pulley trigger wheel assembly, cam chain drive gear and crank in perfect alignment. In motorsport, this has several potential issues. It is quite likely that the loads and vibrations could cause these components to go out of alignment and at the very least cause a loss in performance, the chances are that everything could come completely loose causing catastrophic damage to your engine.
SBD offer a range of components and services to ensure perfect alignment for complete accuracy, this also helps to make the engine easier to assemble and removes the reliance on the crank bolt keeping everything aligned.
