Rusty,
I have the same rattle at about the same rpm.
I spoke to Tracy about this recently. I think he said
it should be at a lower rpm, but even at 1100 or so it's normal and not to worry
about it so long as the run-out remains unchanged. I have my idle set below the
"rattle rpm" so I'm not dwelling in that area much. If you talk with Tracy and
confirm (or deny) this - let me know.
IIRC, the RD1 drives have a low rpm point
where they're known to rattle. I guess this is torque reversals, or
something like that from the engine. Anyway, can someone confirm that this
is true, and tell me what rpm this is supposed to happen at? I've never
been able to idle below 1500 or so, but now, I could probably idle down to 1000
easily. The problem is that I seem to hit this rattle mode at 1100-1200
rpm, so I've got my idle set at 1400 for now.
Thanks,
Rusty (wondering if I
should have inspected the redrive following the oil out)
PS- TIG and Plasma
machines both got 1.5 inches of water before I picked them up, but I dried
them out yesterday, and they both work now (thank goodness).
Fortunately nothing expensive was damaged in the flood, assuming we don't have
to replace the carpet in the great
room.
