Taper Roller Bearing - the mainshaft bearing used in the LT77 and R380 five-speed manual gearboxes, located at the rear of the primary pinion where the front of the mainshaft spigots into it.

The taper roller construction carries the combined radial and axial thrust loads at the front of the mainshaft, locating the shaft as it rotates against the rear of the input (primary pinion) gear. Renewed as part of a gearbox rebuild.

Frequently asked questions

What is the UKC8L taper roller bearing used for?
The UKC8L is the mainshaft taper roller bearing for the LT77 and R380 five-speed manual gearboxes. It sits at the rear of the primary pinion where the front of the mainshaft locates, carrying the combined radial and thrust loads as the shaft rotates. Made by Timken.
Which Land Rover models use this mainshaft bearing?
This mainshaft bearing fits the LT77 and R380 manual gearboxes used in the Defender, Discovery 1, Discovery 2, Range Rover Classic and Range Rover P38. Fitment depends on gearbox type rather than model year, so confirm you have an LT77 or R380 unit.
When should the mainshaft bearing be replaced?
Replace the mainshaft bearing during any LT77 or R380 gearbox rebuild, or when it shows wear. A worn taper roller bearing typically produces a rumble or whine that changes with load, along with play at the mainshaft. Renewing it during a rebuild avoids a second strip-down.
Is the UKC8L bearing cross-referenced to a standard bearing size?
Yes, the UKC8L corresponds to the Timken LM11749-LM11710 cup and cone set, also listed under references BR 0186 and SET1-900SA. These cross-references help confirm you are matching the correct taper roller bearing for the LT77 or R380 mainshaft.
