Frequently asked questions

What does the LT77 cluster gear do?
The cluster gear, or layshaft gear cluster, runs on the layshaft of the LT77 5-speed manual gearbox and carries the constant-mesh gear set. Its teeth stay permanently engaged with the mainshaft gears, transferring drive from the input shaft to the mainshaft speed gears, which the synchromesh hubs then select.
What does military specification mean for this cluster gear?
This FRC7600 cluster gear is the military specification version for the LT77 gearbox fitted to the Land Rover Defender (1983-2006). Military-spec gears were typically built for heavier-duty service. Confirm your gearbox is the LT77 and that the military-spec cluster suits your build before ordering.
What are the signs of a worn gearbox cluster gear?
A worn cluster gear usually shows as whining or growling from the gearbox that changes with gear selection, and in bad cases chipped teeth or metal in the oil. Since it sits on the layshaft inside the casing, it's typically replaced during a gearbox rebuild.
Is fitting a cluster gear a workshop job?
Fitting the cluster gear is typically a specialist workshop job. It runs on the layshaft inside the LT77 gearbox, so the box has to be removed and stripped to reach it. It's usually done alongside the layshaft, bearings and synchromesh during a full rebuild.
