Default Recovering 2.5 hp motor for phase convertor (long story with pictures)

Hi all,

I couldn't resist the 2.5 hp motor I mentioned last week. It took a bit
of thinking and several hours work to get it out of the factory, but I
got there in the end. Today I was excited to discover that this motor
was one of the very first steel framed motors, built in 1931, so it's an
interesting historical item too. I might build a phase convertor with
it, or alternatively save it for driving a machine, but so far I haven't
decided.

Here are the photographs I took. The captions explain what is going on:

A couple of questios too (these are mentioned in the captions). I'm not
sure if the bearings on this motor are intended to be lubricated with
grease or oil. The tubes are currently packed with grease but there
doesn't appear to be any way of forcing it into the bearings, so I can't
see how the system works. See the second from last picture for a view of
the lubrication tubes. Also, I need to free the screws on the motor
mount which adjust the v-belt tension. These are really badly rusted. I
don't mind if I have to make new screws (they are simple threaded rods
with a little tommy bar through the end), but I don't want to damage the
motor mounts. Any ideas?

Hope you enjoy the pictures.

Best wishes,

Chris
