Frequently asked questions

What is the gearbox mainshaft shim used for?
This shim sets the mainshaft end-float during gearbox assembly or overhaul on the manual Land Rover Defender (1987-2006) V8 transmission. The right thickness gives correct bearing preload and keeps the gear cluster aligned in the casing. It's selected to suit, not a one-size part.
How do I choose the right mainshaft shim thickness?
Mainshaft shims come in several thicknesses and are selected to bring the measured mainshaft end-float into tolerance. Measure the end-float during the rebuild and fit the shim that achieves the specified preload. The correct thickness varies between gearboxes, so it's set by measurement, not assumption.
When is the gearbox mainshaft shim replaced?
Re-select or replace this mainshaft shim whenever the manual gearbox is dismantled for overhaul on a Defender (1987-2006). Re-check end-float on reassembly, as worn or incorrect shimming allows excess shaft movement that affects bearing preload and gear alignment. It's a Genuine Land Rover part.
