Frequently asked questions

What is the 231737 thrust washer used for?
The 231737 is a mainshaft thrust washer for the Land Rover Series gearbox, listed at 0.135 inch thick. It controls the axial location of 3rd gear on the mainshaft, limiting end float between the gear and its neighbouring components so the gear runs true.
Which Land Rover models does this thrust washer fit?
This mainshaft thrust washer fits the Land Rover Series 1, 2, 2A and 3 (1948-1984) gearbox, at the 3rd gear position on the mainshaft. It's the 0.135 inch thickness. Fitment records are limited, so confirm the washer thickness needed for your gearbox.
Why does mainshaft end float matter?
Mainshaft thrust washers are selective-fit parts that set 3rd gear end float. A worn or wrong-thickness washer allows excess end float, causing gear rattle or jumping out of gear. These washers come in several thicknesses, so measure the end float and choose the size that brings it within spec.
