I do not have any books apart from Williams and he warns of the difficulty extracting the flange without bending it, esp on some models. He advises driving it off onstead of a 3 arm puller. Nevertheles I prefer to pull using a drilled plate. Whichever, supporting or pushing on the thread it is easy to burr or bend the thread. A stepped nut or collar or washer which fits inside the taper should be fitted and a nut or two fitted tight after this and extending above the thread. Less chance then of bending the threaded part. Maybe a use for the old nut if you can form a collar at one end. If tapers not distorted, as often are, and especially if assembled warm do not need immense pressure on the nut. Must not ride on key. Can rethread smaller but the above precaution then more important. This taper is one where checking with blue and maybe lapping may be helpful with little risk of complications.Must be no steps at end of taper.
If you have split dies these can be clamped onto the thread. Otherwise solid dies and die nuts often start out of phase and remove what is left! 1/2 inch BSF.(Every Javelin has 12 on the driveshaft so any local Club member will likely have many! )
