FJ Gearbox sprocket Nut OE52

Gear Box Sprocket NUT (OE52)
If you find the nut has been done up too tight it will need to be drilled off.
Use a 3mm drill bit and drill across from centre to outer flange. Once the tension has been released the nut will simply undo with your fingers.
A New nut is important. Also important is a new tab washer (OE51).
