Abstract
A filter component includes a cartridge portion including a filter media, and a plug assembly on which the cartridge portion is mounted and in fluid communication with the cartridge portion. The plug assembly comprises a first plug and a second plug, the first plug being larger than the second plug. The second plug is fixed to an inner surface of the first plug in an installed state and is removable from the first plug in a draining state. The first plug further defines a drain port, wherein in the installed state the second plug plugs the drain port and in a draining state the second plug is removed from the first plug to permit draining fluid through the drain port. The filter component may be incorporated into a hydrostatic transmission to permit controlled draining of fluid from the hydrostatic transmission that does not result in an oil mess.
