Cluster Gear for the LT77 five-speed manual gearbox, part of the layshaft geartrain.

The cluster carries the constant-mesh gears that run continuously with their mainshaft counterparts. Drive taken from the input shaft is carried through the cluster gears to the mainshaft, where the selected forward ratio is engaged. The condition of the cluster teeth and bearing surfaces directly affects gearbox noise and the smoothness of ratio changes.

Frequently asked questions

What does the FRC8142 cluster gear do in an LT77 gearbox?
The FRC8142 cluster gear carries the constant-mesh gears on the layshaft of the Land Rover LT77 five-speed manual gearbox. Drive from the input shaft passes through the cluster to the mainshaft, where the selected forward ratio is engaged. Its tooth and bearing condition affects gearbox noise and shift smoothness.
What are the symptoms of a worn LT77 cluster gear?
A worn LT77 cluster gear typically causes gearbox whine, noise on particular ratios, or notchy shifting, because its teeth run in constant mesh with the mainshaft gears. Chipped or worn teeth and pitted bearing surfaces are the usual causes. Continued use can damage the mating mainshaft gears.
How do I confirm the FRC8142 cluster gear fits my gearbox?
The FRC8142 cluster gear typically fits the Land Rover Defender 90 and 110 LT77 five-speed manual gearbox, including the noted LT77 military gearbox application. Confirm your gearbox is an LT77 and check its internal ratios before ordering, since LT77 clusters typically aren't interchangeable with R380 boxes.
