So this morning, being a public holiday with perfect weather, I tackled the damaged thread on the Lower suspension arm with the "tap", the tap is a bit on the soft side, but after dressing the tap and the plug threads with a thread file, dressing the entrance of the plug hole with a rotary file, a lot of grunting, shoving, bitching, lubricating, swearing, the hole threads were chased, plug reinstalled and wheel replaced. Now I am all smiles.
I have been promised useable wheel reduction box spares from England at a reasonable price at the end of this month, so the next obstacle will be that dreaded wheel reduction box. I am rather nervous about the correct assembly of this wheel station, I don't want to see a repeat!
Last big challenge will be the replacement the oil seals on the lefthand centre bevel box. Have already procured the seals, so it is a matter of taking things apart for the replacements!
