Seal insertion tool for aircraft NG hubs

Progressive development of grease management in new generation aircraft wheels has seen the introduction of improved sealing methods. The installation of these generally larger and stiffer seals requires considerably more effort than previously. Therefore a  seal insertion tool for aircraft NG hubs is required.

Solution:The seal insertion tool is a capstan device with four rollers that can be radially pre set to match the seal diameter. The tool will drive the seal to its seating by rollers imparting pressure at the seal rim while rotating, thus pushing the seal to its seat.
