[TR] loss of damper oil

[Chris Kantarjiev]

Dave Massey gave you good instructions on replacing the O-ring ...
but it might not (yet) be obvious that you can remove the
piston by "simply" removing the dashpot cover and lifting out
the entire assembly.

A few things to note:

- The four screws are pozidrive, not phillips. It matters.
- Don't tear the diaphragm while removing it.
- Note that there is a tab on the diaphragm to locate it
properly.
- Don't tear the diaphragm while removing it.
-
- Don't tear the diaphragm while replacing it.

Best,
