FRC4810 - Gearbox Plug Sealing Washer
This sealing washer fits beneath the thread of gearbox plugs to prevent oil seepage past the seat. On LT77 gearboxes it also seals the extension case plug and oil pump fitting positions, and the V8 gearcase plug points. It should be renewed each time the associated plug is removed to maintain an oil-tight seal.
