Mounting Orientation

The FCNDK Gearboxes are pre-filled with synthetic oil. This has to be filed according to the orientation that the gearbox will be used in and must be specced when purchasing to avoid invalidating the warranty and premature failure of the gearbox.

Please see the help sheet, to determine which orientation you require and then select in the drop-down menu above when adding the gearbox to your cart.
