Crownwheel and Pinion Set - 3.54:1 final drive ratio (13-tooth pinion, 46-tooth crownwheel), for the two-pinion differential used in the Land Rover type axle. Suitable for front or rear differential use.

The pinion takes drive from the propshaft at the drive flange and turns it through 90 degrees into the crownwheel, which is bolted to the differential carrier and drives the differential gear set and the halfshafts. This version has a female M12 threaded pinion and accepts a 24-spline drive flange.

The crownwheel and pinion are lapped together as a matched pair at manufacture and must be supplied and fitted together - neither gear may be replaced individually, and gears from different sets must never be mixed. Fitting requires the pinion bearing preload and the crownwheel backlash to be set with shims, and the tooth contact pattern to be checked, before the differential is returned to service.

Frequently asked questions

What is this crownwheel and pinion set and what ratio is it?
This crownwheel and pinion set has a 3.54:1 final drive ratio, using a 13-tooth pinion and 46-tooth crownwheel, for the two-pinion Land Rover-type axle. The pinion turns drive from the propshaft through 90 degrees into the crownwheel, which drives the differential and halfshafts. It suits front or rear differential use.
Which vehicles does this 2-pinion crownwheel and pinion fit?
This crownwheel and pinion fits the Land Rover Defender 1987-2016 and the Discovery 1 1989-1998 front differential, VIN FA393361 to WA799999. It is a two-pinion Land Rover-type axle set. Confirm your axle type and ratio before ordering.
Can the crownwheel and pinion be replaced separately?
No, the crownwheel and pinion cannot be replaced separately. They are lapped together as a matched pair at manufacture and must be supplied and fitted together. Never mix gears from different sets, as the tooth contact will be wrong and the gears will whine or fail.
What is involved in fitting this crownwheel and pinion?
Fitting this crownwheel and pinion is a specialist job. The pinion bearing preload and the crownwheel backlash must be set with shims and the tooth contact pattern checked before the differential returns to service. It is not a bolt-in replacement.
