Planet gear 450/10206 is a genuine JCB part for the JCB 3CX and 4CX backhoe loaders. This gear is a planet gear of the planetary gearbox.

The gears are chosen by part number according to tooth count, module and spline form, and front and rear versions of the same axle may use different gears. The planetary oil is changed with the type and at the interval the maker specifies, since a low oil level wears the teeth quickly. After new gears are fitted, the first oil change can be done earlier.

JCB 3CX / 4CX Rear Axle Overheating: Causes and What to Check
The rear axle of a JCB 3CX or 4CX backhoe loader runs hotter than the front axle by design: it houses the oil-immersed service brakes, one multi-plate brake pack on each half shaft. A warm axle casing after a shift is therefore normal. It becomes a concern when the axle gets very hot after an ordinary road run, the machine feels as if it is dragging, there is a smell of burnt oil from the axle, or oil starts leaking past the seals. The usual cause is brake drag: the service brakes or the park brake are not releasing fully. Below, based on the JCB service manual, is what to check and in what order.
