Elevator Hinges - Part 3

Before fitting the D Nose the hinges were assembled and installed.

All components are supplied with the kit but required assembly by the builder. The mounting angles are counter bored on the inside face to accept the spherical bearings supplied. As part of the installation are eight [8] turned aluminium spacers and they are easily lost - wire them together until needed.

Installing Bearings
Aluminium sheet is for protection when
driving the bearing

The bearings are a press fit and required a firm wack to install them. The edge of the bearing's were dressed using a points file by drawing it backwards around the rim perimeter to refine the rim. With the bearing inserted squarely on the opening it was driven using a 3/8'' diameter x 1/4'' drive socket placed on the rim and struck firmly with the 8 ounce hammer.

Once assembled the two half were brought into alignment using the 8 oz hammer. 

Note: A aluminium scrap was used on both side's for protection of the hinge.

Ready to assemble

The aluminium spacers are fitted at both sides using the 2 oz hammer. A couple were a loose fit and were treated Loctite at assembly ensuring that none lodged on the bearing. At this point wire up each assembly using lock wire as they can be lost and are a bear to find. 

The required AN3 bolts and washers were assembled and fixed using the previously installed captive nuts.
