I'm not sure if an original HMV 101 owner's manual would be of much help. From what I've heard, it provided basic operational instructions, but that's about it. (Could some of this site's gramophone experts confirm this?)
If you want comprehensive information about taking down, cleaning, greasing, and reassembling a gramophone motor, along with general servicing tips, probably the best source would be "The Compleat Talking Machine" by Eric Reiss. (That's the way "complete" is spelled in the title.) The book provides an excellent guide for new as well as more advanced collectors, and is packed full of illustrations. If you do a search for the title on
http://www.google.com, you'll see a number of sellers listed, such as Amazon.com.
Along this line, there are also a few youtube videos that show how to remove and repair gramophone mainsprings, such as --

While there is nothing specific for the HMV 101, all gramophones shared the same, basic components -- mainsprings, governors, winding shafts, etc. For instance, even though the spring barrel is positioned differently, the VV 50's lubrication instructions would apply to your model --
