Frequently asked questions

What is the 1.93mm LT77 gearbox shim for?
The 1.93mm 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, and the thickness is selected on assembly to bring the bearing within specification.
How do I know the 1.93mm shim is the right thickness for my gearbox?
The 1.93mm shim is selected by measurement during the LT77 build to set primary shaft end-float, so it's chosen from a measured stack rather than by model. Fit the thickness that brings the bearing within the workshop manual figure for your gearbox.
Which vehicles use the LT77 1.93mm primary shaft shim?
This 1.93mm shim fits the Defender, Discovery 1, and Range Rover Classic with the LT77 five-speed manual gearbox. On the Defender it applies from VIN (V)LA939975, and Discovery 1 from (V)LA081991. Confirm your gearbox build by VIN, as shim thickness is selective.
