Removing and Installing 206 TRB Bearings

Van Horn Aviation provides two resources for authorized repair personnel who replace bearings in VHA 206 series tail rotor blades. These include Technical Bulletin TB 2062200-1 and a How-To video. The resources were created after Van Horn Repair (VHA's in-house repair station) found many VHA 206 tail rotor blades were being sent in for bearing replacements that actually did not need replacement. Several blades have also been sent in for repair after being damaged by improper bearing removal or installation. 

Both the video and the technical bulletin provide guidance on the following topics:

• Removal procedures for non-pre-swaged bearings (WC-6TG-8) and bearings pre-swaged on one side (WC-6TG-10 and Kamatics KSC627506FS)
• Tools and equipment needed for successful bearing removal and installation
• Installation procedures for WC-6TG-10 pre-swaged bearings
• Final inspection using a feeler gauge

Repair personnel are encouraged to read the tech bulletin and watch the video before removing / replacing any bearings.
