The generator and gearbox on the E-4660 are connected via a flexible coupling.
This is comprised of two metal flex plates and a 280mm long connecting hub. The flex plates are a wearing item subject to maintenance but have been known to fail within the normal 6-month service schedule.
If flex plates fail in service the connecting hub has the tendency to flail around causing significant damage to other parts, including the brakes.
We are pleased to be able offer our customers an upgraded coupling that is designed to prevent secondary damage in the event of flex plate failure.
