No. We're DONE on the subject of the RH-5's. There will be no more discussion about servicing them on *this* web site.
They are illegal to work on, per USDOT. And there are lots of suitable replacements to be found out there very reasonably. I was able to rapidly, easily and cheaply source 6-lug single piece wheels for my firetruck a few years ago. You can, too.
End of discussion.
