My course of action now will be to "wait and see". If it appears that my blower is too small after everything is hooked up, I will have the flexibility to find a larger one and install it in the same space. I am also looking at the possibility, if necessary, to run the Echo and console from a small separate blower(s).   When I purchased my Aeolian in 1998, it was still playing, though poorly. At that time it was impossible to evaluate the blower's capabilities. During removal, we found two things that were a great hindrance to the blower. First, a rodent had made a sizable hole in the relief pneumatic = of the pedal regulator. Second, lodged in the blower intake was a crumpled aluminum pie tin. The tin was rolled into a 4 inch ball. It seems that the previous owner used pans of water around the blower to raise the humidity. When we mentioned this to someone familiar with the instrument, he replied, "Yeah! That blower used to make a lot of rattling noise!".   Bob Taylor

Taylor" <rtaylor@sockets.net> Date: Sat, 3 Feb 2001 11:20:47 -0600   While I am not an expert on lubrication, I do know that electric motors = and fan bearings should not be lubricated with oil designed for internal combustion (IC) engines. IC engine oil contains additives necessary to combat the effects of mixing by-products of combustion with the lubricant. There is always some blow-by in every engine. That is why engine oil becomes dirty and must be changed in your automobiles. Additionally, IC lubricants must remove heat from the bearing area (cylinder walls) as well as coat the metal with protective film.   The additives can contain rust inhibitors, detergents, and ash. These things might harm electric motor bearings. The damage may not appear for years. Unlike car engines, electric motors do not consume oil. If the seals are tight, only small amounts of oil are necessary to keep the bearings healthy. Any electric motor shop can give guidance to the proper lubricants. The oil you use should say "For Electric Motors" on the container.   Bob Taylor

These really were designed for an oil such as a straight 30 weight mineral oil. I don't think that the detergents in auto oil really will harm it much. You can get non-detergent 30 weight as 3-in-1 "motor" oil.
