Frequently asked questions

What is the Needle Roller Bearing (RTC6129) used for?
The RTC6129 is a needle roller bearing that supports the worm and input shaft inside the manual, non-power-assisted steering box of the Gemmer type. It keeps the worm and sector shaft assembly correctly meshed and free to rotate. It's an OEM Timken bearing for the Defender (1987-2006).
Does the RTC6129 fit power steering boxes?
No, the RTC6129 fits the manual non-power-assisted steering box (Gemmer type) only, not power steering boxes. Check which steering box your Defender has before ordering, since the two use different internals. This bearing is also listed under part number BAU4864.
Where does the RTC6129 bearing sit in the steering box?
The RTC6129 sits inside the manual steering box housing, supporting the worm and sector shaft assembly so the steering input shaft turns freely with correct mesh. Reaching it means removing and dismantling the steering box, so it's typically replaced during a steering box rebuild.
