Frequently asked questions

What is the 1-Ton mainshaft and what does it do?
The mainshaft is the output shaft of the LT76 four-speed manual gearbox. It carries the main gear cluster and transmits drive through to the transmission output on the Land Rover Series 3 1-Ton.
Which gearbox does this mainshaft fit?
This mainshaft fits the Series 3 109-inch 1-Ton with the LT76 four-speed gearbox only. It's specific to the heavy-duty 1-Ton build and won't fit the standard LT76 gearbox, so confirm your gearbox type before ordering.
When does the gearbox mainshaft need replacing?
Signs the mainshaft needs replacing typically include gearbox whine, difficulty holding gear, or worn splines and bearing surfaces found during a strip-down. It's usually renewed as part of a full LT76 gearbox rebuild rather than on its own.
