Frequently asked questions

What is the mainshaft bearing and where does it sit?

The mainshaft bearing is the gearbox centre bearing that carries the mainshaft within the casing, holding it in alignment as it turns under drive. On the Land Rover Series 2 and 3 main gearbox it's a known wear point and is usually replaced when the box is stripped for an overhaul.

How does this aftermarket bearing differ from the OEM mainshaft bearing?

This is the aftermarket version of the Series 2 and 3 mainshaft bearing, supplied by Britpart, while the OEM equivalent is stocked separately. Both fit the same gearbox mainshaft centre support listed for the 1958 to 1961 Series II 2.0 petrol. Dimensions match, so choose on brand and warranty preference.

Should the mainshaft bearing be replaced on its own?

Replacing the mainshaft bearing usually means stripping the Series 2 and 3 gearbox, so most rebuilders renew the other gearbox bearings at the same time rather than return to the job later. The bearing presses onto the mainshaft centre support. It's a specialist gearbox task rather than a roadside fix.
