This grease is also available from Grainger (which might be easier to locate 
without having to place a mail order). Their catalog lists a stock number of 
4ZF49 and price of $6.43 each for a 12.5 oz. cartridge.

That's a ship load of grease if you are only doing one dynamotor .... so I 
also tried it when recently repacking my bicycle wheel bearings. :-)

The cartridge is pretty generic so you have to look close for the fine 
printing to see that it is "SHC-100" .... unless you pay attention to the 
color of the grease. It is bright red.
