Wurlitzer Gearbox Lubrication
By Jack M. Conway

Hi Group, Clark McNally asked about Wurlitzer Gearbox Lubrication
[061030 MMDigest].  The 1923 Wurlitzer publication, "The Wurlitzer
Long Roll Tracker Frame Care and Use," has the following:

  "Instructions For Care of Style B Gear"

  "It is absolutely essential that this gear standard is properly
lubricated.  This gear standard is constructed so that it is self-oiling,
by means of the splash oiler system.

  "_Use only the best grade light lubricating oil in this gear.  Never
use heavy grease and do not under any circumstances, mix graphite or
any other lubricating substance with the oil as this will put the
splash system out of order in a short time and will result in serious
trouble_.

  "The oil should be emptied into the casting which protrudes under
the crank shaft in the standard, there being a hole in the bottom of
this which allows the oil to run down to the oil well at the bottom of
the standard.  You can determine the amount of oil to put in the gear
standard by means of the oil gauge on the side of the gear.  Always
have enough oil in the gear so that it shows in the oil gauge (Y-219-HG).
Care should be taken in putting in the oil, so that it is not filled
any higher than half the diameter of this gauge, or it will overflow at
this point, and if allowed to get down on the bellows will soon ruin
them."

The next page has an illustration, "Cross Section drawing of Style BB
gear Showing Parts With Numbers."  It shows part (Y-219-HG) as a
threaded plug on the left side of the case plugging a hole into the
well of the gear standard.  The gauge on my Wurlitzer BX is on the
front of the gear case and has a sleeve, with a hole in it, that turns
to match a hole in the plug to let oil run out.  I guess the idea is
that if no oil runs out it is low and if it flows freely it is too
full.
