I have found a spare idler damper for Albert Boasberg's 2000TC, but it
has brought up a few questions. It appears to be in good condition --
the shaft turns in the body without any apparent play or looseness in
the bushings; no sign of leaks. I noticed however, that the hydraulic
resistance as I turned the shaft was not completely steady at first.
Now that it has been sitting upright in the vice for a while and it has
been exercised back and forth several times, the hydraulic action has
smoothed out. (I take the unsteady damping to be some air mixed with
the damping oil after turning the damper right side up.)
I got to wondering whether the oil in the unit should be topped up and
then I discovered that the manuals call for "no maintenance" on this
part. I have a vague memory of topping these dampers up with engine
oil 25 years ago (!) on my grandfather's 2000TCs -- maybe I'm thinking
of some other part.
What is the collective wisdom on these dampers -- should the oil be
topped up and with what fluid? Are they really not rebuildable as the
manuals claim? How do these units tend to fail -- wear, leaks?
