Frequently asked questions

What does the LT77 mainshaft spacer do?

The LT77 mainshaft spacer sets the axial position of the gears and bearings along the gearbox mainshaft, maintaining correct end-float within the gear train. It fits the LT77 five-speed manual gearbox and is a non-wearing setting component within the transmission.

When is this mainshaft spacer usually replaced?

This mainshaft spacer is usually handled during a gearbox strip or rebuild, when end-float is being set on the LT77 mainshaft. It's typically renewed if worn or damaged, or if a different thickness is needed to correct end-float. It isn't a routine wear item.

This spacer fits Land Rover models running the LT77 five-speed manual gearbox, including Defender up to 2016, Discovery 1 (1989-1998), and Range Rover Classic. Confirm your vehicle has the LT77 gearbox rather than a later R380 before ordering.
