In response to customer requests, Van Horn Aviation posted the instructions for field replacement of bearings in its 206/OH-58 tail rotor blades. Operators and their maintenance personnel can download Customer Support Specification CSS-500 WC-6TG-8 Bearing Installation Rev. B from the VHA Documents page.
Maintenance personnel with proper equipment may replace the bearings in the field using the procedures described in the VHA CSS-500 WC-6TG-8 Bearing Installation document. The procedure requires the use of a hydraulic press to remove bearings, bearing swaging tool and locating fixture (purchasable from VHA), table-mounted arbor press, and manual milling machine or drill press.
Operators may also contact VHA’s repair station, Van Horn Repair for bearing replacement.
