Frequently asked questions

What is the RTC2990 crown wheel and pinion and what does it do?

The RTC2990 crown wheel and pinion is the final-drive gear set inside a Land Rover axle. It transfers drive from the propshaft into the axle, turns it through 90 degrees to the wheels, and provides the final gear reduction. It's a matched pair, so the crown wheel and pinion are always fitted together.

What ratio and spline count does the RTC2990 have?

The RTC2990 has a 47/10 tooth count, giving a 4.7:1 final-drive ratio, on a 10-spline pinion. Both axles on the vehicle must run matching ratios, so check the crown wheel and pinion in the opposite axle is also 4.7:1 before fitting.

Which Land Rovers does the RTC2990 fit?

The RTC2990 fits Land Rover Series 2 and 3 and Defender models up to 2016. On Series 3 it's the front axle crown wheel and pinion for 2.25 petrol (except 109 1 Ton) and 2.6 six-cylinder petrol (except 1 Ton). Confirm your axle's ratio and spline count before ordering.

Why would a crown wheel and pinion need replacing?

A crown wheel and pinion typically needs replacing when the gears whine, howl, or show chipped or worn teeth, usually from age, low oil, or heavy off-road use. On assembly the pinion depth and backlash must be set for correct tooth contact, so it's usually a specialist job needing a setup gauge.
