Frequently asked questions

What does the RTC2684 primary pinion do?
The RTC2684 primary pinion is the input gear for the LT76 manual gearbox. It takes drive from the clutch and passes it into the gear train, meshing with the layshaft cluster to drive the mainshaft gears. It forms the first stage of power transmission through the gearbox.
What does suffix D onwards mean for fitment?
Suffix D onwards means this primary pinion is specified for the LT76 gearbox built to suffix D and later. The LT76 gearbox changed through its production life, so the suffix has to match. Check your gearbox suffix before ordering, as an earlier-suffix box may use a different pinion.
Which vehicles use this LT76 primary pinion?
This LT76 primary pinion suits Land Rover Series 2/3 and classic Defender models fitted with the LT76 manual gearbox, suffix D onwards. Because it's specific to the LT76 gearbox rather than a model year, confirm your vehicle has that gearbox and the correct suffix before ordering.
What are the signs a primary pinion needs replacing?
A worn primary pinion usually shows as whining or growling from the gearbox, difficulty selecting or holding gears, or chipped and worn teeth found on inspection. Because it's the input gear, damage here affects all forward gears. It's typically replaced during a full gearbox rebuild rather than on its own.
