Oil Pump Inner Gear - the inner (drive) gear of the gearbox oil pump, within the lubrication circuit of the main gearbox.

Driven from the gearbox, the inner gear meshes with the outer rotor to draw and pressurise oil, circulating it through the gearbox to lubricate the gears and bearings.

Fitted to solid-case gearboxes equipped with an oil pump; split-case boxes do not use a pump.

Frequently asked questions

What is the 90571086 oil pump gear used for?

The 90571086 is the inner drive gear of the gearbox oil pump. It meshes with the outer rotor to draw and pressurise oil, circulating it through the gearbox to lubricate the gears and bearings. It's fitted to the LT85 5-speed manual gearbox.

Which vehicle and gearbox does this oil pump gear fit?

This oil pump gear fits the Land Rover Defender with the 3.5L V8 petrol engine and LT85 5-speed manual gearbox. It's used in solid-case gearboxes that have an oil pump; split-case boxes don't use one. Confirm your gearbox is the LT85 before ordering.

What happens when this oil pump gear wears out?

A worn oil pump gear loses the ability to maintain oil pressure in the LT85 gearbox, which can starve the gears and bearings of lubrication. Signs include gearbox noise, overheating, and accelerated internal wear. Replacing the gear restores proper oil circulation through the box.

Is fitting this oil pump gear a DIY job?

Fitting this oil pump gear means removing and opening the LT85 gearbox to reach the oil pump, so it's typically a specialist job rather than a roadside fix. Inspect the outer rotor and pump housing while the box is apart, as they wear together.
