Frequently asked questions

What is the RTC1963 Tab Washer used for?
The RTC1963 primary pinion tab washer is a locking washer fitted beneath the primary pinion retaining nut in the Series gearbox. Once the nut is tightened, one tab is bent against a flat of the nut to lock it and stop it loosening in service.
Can the tab washer be reused?
No, tab washers are single-use. Once a tab has been bent against the nut and then flattened to remove it, the metal is fatigued and won't lock reliably again. Fit a new RTC1963 every time the primary pinion nut is disturbed on a Series gearbox.
Which Land Rovers does this tab washer fit?
This primary pinion tab washer fits Land Rover Series 1 (1948-1958) and Series 2, 2A and 3 (1958-1971) gearboxes, including the 4-speed suffix A to C boxes. Fitment is derived from research, so compare against your existing washer if unsure.
