When installing lower bearing, I found only 2 bolt-holes drilled in right position of black plastic bearing. Not mentioned in manual, butI drilled 4 new. Installed AN3-6 bolt, washer and locknuts temporary. Will be torqued later when nose-gear is installed. Mounted upper bearing together with stiffernes and angles. Removed clecos from diagonal angles on rear side, and rivet from frontside. Also 6-W-6-1 angle rivered from front side.
