The Transfer Gear Breather Vent is used to prevent the buildup of moisture and pressure in the transfer gear housing. It is located on the top of the housing and is connected to a filter element. As the gears rotate, they create a vacuum inside the housing, which draws air through the filter element and into the housing. This air helps to remove moisture and cool the gears.Attributes:• Manufactured to precise specifications and are built for durability, and reliability • Helps to keep the transfer gear lubricant coolApplications: The Transfer Gear Breather Vent is used to allow air to enter and exit the transfer gear housing, equalizing the pressure and preventing the buildup of excessive pressure or vacuum.
