It seems that it was placed in a pile of miscellaneous things when the balcony was cleaned this fall---I'm glad I found it before they threw it out!! The oil is now in a bag that is permanently attached to the organ supports. Thanks to all for your help.   Paul   __________________________________ Do you Yahoo!? Yahoo!

I therefore reasoned that = sewing > machine oil might be a good substitute for the Laukhuff lubricant.   Synthetic oils are wax-free, but I believe that sewing machine oil is = simply an ordinary mineral oil.

To find out for sure, you could:   1) Call Laukhuff and ask. Be nice. :-) 2) Call the local ExxonMobil lubes distributor and ask for help. 3) Check out ExxonMobil's laboratory assistance at: http://www.mobil.com/USA-English/Files/Lub_Compatibility_Assessment.pdf   Regarding seal material compatibility, quoted from the site: http://www.mobil.com/USA-English/Lubes/PDS/GLXXENINDMOMobilSHC600Series.asp=     "The Mobil SHC 600 Series oils are compatible with the following seal = materials: fluorocarbon, polyacrylate, polyurethane ether, some silicone, = ethylene/acrylic, chlorinated polyethylene, polysulfide, and some nitrile = rubbers. There is the potential for substantial variations in the = elastomers being used today. For best results, consult your equipment = supplier, seal manufacturer, or your local Mobil representative to verify = compatibility."   Does anyone know what the seals are made of in Laukhuff's blower motors? = It's unlikely to be anything unusual, since it's an indoor, low = temperature, low pressure, low speed application.   Best Regards, Dave Doerschuk
