Hitachi parts

The center pivot on my UH083 has given up. At first I figured just seals would fix the leak. After getting the whole assembly out of the machine and taking it apart on the bench it looks like I need the spindle. The housing looks good but the spindle is galled.
According to the manual, the part #1005892 is what I need but it's NLA. I suppose I could send it out to be built up and turned but would rather get a replacement part.

Do any of you guys have a source for a 1005892 spindle?
