ABSTRACT:
A lubricant filled drive assembly is disclosed having an insert to displace a portion of the required volume of lubricant. The insert is shaped so as to receive interchangeable or optional pieces of drive assembly equipment, and when certain pieces of equipment are not used, plugs are added to the assembly to occupy the empty space within the insert. By eliminating any unoccupied space, the plugs alleviate the need for additional lubricant which might otherwise be a cost of adding flexibility to the gear drive. The insert and plugs are preferably coated with a lubricant impermeable layer.
