Frequently asked questions

What does the 3rd/4th synchro hub do in a Series gearbox?

The 3rd/4th synchro hub carries the synchroniser mechanism in the LT76 Series-type manual gearbox. It matches mainshaft and gear speeds during changes between 3rd and 4th so the sliding sleeve engages cleanly without clash. It locates on the mainshaft between the 3rd and 4th gear wheels.

Which gearbox and models does this synchro hub fit?

This synchro hub fits the LT76 Series-type manual gearbox used on the Land Rover Series 1, Series 2 and 3, and early Defender up to 1983. It's an aftermarket part covered by a 3 year guarantee. Confirm your gearbox is the LT76 unit before ordering.

What are the signs a 3rd/4th synchro hub needs replacing?

A worn 3rd/4th synchro hub typically shows as crunching or baulking when changing between 3rd and 4th, especially on quick shifts. The gear may be hard to select or jump out under load. Worn synchro parts are usually replaced together with the sliding sleeve while the gearbox is stripped.

How do I confirm this synchro hub fits my Series gearbox?

This synchro hub fits the Land Rover Series 1, Series 2 and 3, and early Defender up to 1983 built with the LT76 gearbox. Because Series gearboxes changed through production, check your mainshaft and 3rd/4th gear arrangement against the part before fitting.
