Turbine Pump Lubrication & Bearings
By David Sharpe

I thank Spencer Chase for the suggestion to replace the bearings.
In the best of all possible worlds that is what I would do.

However, I do not have facilities for machining to get a new bearing
to fit.  Also I suspect my pump is in fairly good condition.  Dates
scratched on the pump box indicate that it was lubricated at least
every two years for the first 20 years of its life.  The dates are
further apart after 1947 but I suspect it was used less often then too.
I eventually plan to install a Player Piano Co. remote pump, but in
the meantime I would like to play rolls occasionally and not worry that
I have not lubricated the pump.

I can't believe everyone else who has one of these turbine pumps has
replaced the bearings.  So I ask again, given that I plan to use the
pump in its original condition for a while, can someone please tell
me what he or she lubricates the bearings with?

 [ The "proper" or "best" oil lubricant has a long life and
 [ doesn't need to be checked very often, but any light machine oil,
 [ such as sewing machine oil, will work if you will regularly check
 [ that it still flows properly and is clean.  Player pianos equipped
 [ with the turbine pump are relatively rare; that's most likely why
 [ no MMDer has the answer to your question.  -- Robbie
