Main shaft bearing R/R

Is there a vid here for this or do I just use a vise and a couple of sockets to press bearings out?

Yes, just tap the old one out or press out with a socket, clean housing and OD of bearing with solvent, apply a thin layer of Loc-tite blue to the OD of the bearing and press the bearing in. A vise is the best way I have found to press it in. Make sure the bearing is fully seated. Use a rag to protect the housing in the vise. Wipe off any excess Loc-tite and re-install in heli.

Yep.. I have one socket that fits the hub, and its a deep socket, and I have one that fits the OWB and spacers perfectly. I used a 6" extension on the socket that fits the OWB... I didnt have to use a vice.. I just stood the bigger socket on end, sat the hub on it..( yes, with the main gear still one it..) and tapped out the spacers and OWB into the bigger socket. Sat the whole thing on my workbench and tapped them all back in with the new OWB.
