Next step is installing rod end bearings. I got this
little tool from Avery. It allows you to fit it over the end
of the bearing and turn it without damaging the bearing.
Works great. |
| |
 Step 1:
Install MD3614M Rod End Bearings and AN316-6 Jam Nuts into
both elevators as shown in Figure 1. Tighten jam nuts after
achieving the rod end bearing engagement called for in
Figure 1. Detail A |
|
 Step 2:
Attach the horizontal stabilizer to the workbench using
four "drywall" type screws as shown in Figure 12. Position
the stabilizer on the workbench such that the tips hang over
the edges of the workbench. |
|
 Step 3: Temporarily
install the left elevator to the horizontal stabilizer as
shown in Figure 3. Elevator attach hardware is shown in
Figure 3, Detail A. Not filling the gap between the elevator
horn and the VA-146 with washers and then tightening the
bolt to remove the gap may cause slight binding in the rod
end bearings.
Perform an initial check to se that
the elevator rotates freely and with no interference. If the
elevator's leading edge rubs against the horizontal
stabilizer gently "message" the leading edge to provide
clearance. Should additional clearance be required, the
elevator rod end bearings may be adjusted out up to 1/16
inch further than the dimension in Figure 1, Detail A. There
should be 1/8 inch gap between the outboard edge of the
horizontal stabilizer and the inboard edge of the elevator
counterbalance arm.
Final check for 30 degrees "UP" elevator travel and 25
degrees "Down" elevator travel as shown in figure 4.
Elevator travel is best measured using a protractor or and
electronic "smart level" |

| Step 1: Locate
the steel E-Drill Bushing provided in the kit and shown in
Figure 1 below. The drill will be used to protect the hinge
bearing from the drill bit when match-drilling the elevator
horns to the inboard elevator hinge point |
|
 Step 2:
Insert the E-Drill Bushing into the VA-146 Elevator
Center Bearing as shown in Figure 2. Match Drill #17 the
WD-605-L-1 Left Elevator Horn using the E-Drill Bushing as a
drill guide. |
|
|
Step 3:
Remove the left elevator from the horizontal stabilizer.
Final drill the hole in the WD-605-L-1 Elevator Horn to
1/4 inch and deburr the hole. |
| Step 4:
Repeat Page 11-2, Step s 3 and 4 and Steps 1 through 3 for
the right elevator. |
|
 Step 5: Install
both right and left elevators to the horizontal stabilizer.
See Page 11-2, Figure 3 for the hardware call-out. Secure
both elevators in the "trail" position by placing strips of
duct tape over the gap between the elevator counterbalance
arm and the horizontal stabilizer |
|
|

Step 6: With both
elevators in the "trail" position there will most likely be
a mismatch in position between the bottom end of the
WD-605-L-1 Elevator Horn and the bottom end of the
WD-605-R-1 Elevator Horn, Identify which of the two elevator
horns is the most aft. |
|

Step 7: In the most aft
WD-605-1 Elevator Horn, locate and drill a 3/16 inch hole as
shown in Figure 3. |
| |
| Step 8:
Measure the span wise distance between the WD-605-L-1 and
WD-650-R-1 Elevator Horns. |
| |

Step 9: Make or
otherwise acquire a block of wood/plastic/metal that is the
same thickness or up to 1/32 inch less than the distance
measured in Step 8. The block should be 3/4 to 1 1/4 inch
wide and 2 to 3 inches long. This Drill Guide Block will be
used to keep the bit perpendicular when drilling from one
elevator horn to the other. A stack up of blocks is
acceptable if a single block the correct thickness is not
available. Use a drill press to drill a 3/16 inch diameter
hole in the block(s) 1/2 inch from one end. The hole must be
perpendicular to the drill guide block. |
| |

Step 10: Insert a
3/16th bolt through the hole drilled per Step 7 in the
WD-605-1 Elevator Horn. Place the Drill Guide Block against
the elevator horn with the bolt passing through the hole
drilled per Step 9. Clamp both elevator horns together with
the drill guide block between them then double check that
both elevators are aligned in trail. |
| |

Step 11: Remove the 3/16 bolt
from the WD-605-1 Elevator Horn and Drill Guide Block.
Match-Drill #12 a hole in the elevator horn using the
elevator horn and drill guide block to aid alignment. Drill
the hole as straight and square as humanly possible. |
| |
 Step 12:
Remove the clamp and Drill Guide Block from the WD-605-1
Elevator Horns and then remove the elevators from the
horizontal stabilizer. Reinstall the elevator attach
hardware finger tight in the horizontal stabilizer hinge
brackets so that it won't get lost. Deburr the holes in the
elevator horns and set elevators aside.
Note I put the stab in place try to
figure out how to work on it. I acquired this old adjustable
height table from a War Surplus store and rebuilt it. It
appears to be just the ticket as it rolls around with the
tailcone on top very easily and I can adjust the height to
the level I need. |
