Frequently asked questions

What is the 1.75mm LT77 gearbox shim for?
The 1.75mm shim sets the primary shaft bearing preload and end-float in the LT77 five-speed manual gearbox. It fits behind the gearbox front cover at the primary shaft bearing. Its thickness is selected on assembly to bring the shaft bearing within specification.
When would I choose the 1.75mm shim over a thinner one?
Choose the 1.75mm shim when measurement during the LT77 build calls for that thickness to set the primary shaft bearing end-float correctly. The shim is selective, so the right thickness depends on the stack of components in your gearbox, not on the model alone.
Which Land Rovers take the LT77 1.75mm primary shaft shim?
This 1.75mm shim fits the Defender, Discovery 1, and Range Rover Classic running the LT77 five-speed manual gearbox. On the Defender it applies up to VIN (V)LA939975. Confirm your gearbox variant by VIN before ordering, as shim thickness is selected per build.
