These instructions cover the installation for a Piper PA30, PA34, and PA40 with the Knots2U Arapaho
windshield configuration. The longer Arapaho windshield eliminates the mounting position over the
windshield.
•
If there are existing visors, remove them.
•
On the pilot’s side remove enough of the interior linings
to gain access to the aircraft interior metal structure in
the upper corner where the side window meets the front
window.
•
Do the same on the copilot side where the door jam is.
•
On each side, position the round mount against the
structure and orient it sot he post is as vertical as
possible. Both sides should be at the same height in
the aircraft.
•
Mark the three mounting holes on each side.
•
Drill all marked locations to .221/.226 diameter. Note:
Drill only through interior sheet metal. Maximum depth
must not exceed 1/4 inch.
•
Use a small rat tail file to put a 1/26” notch in each
hole for the key in the rivnut.
•
Install the rivnut using appropriate tooling.
•
Trim and or return the interior linings into position. If
necessary cut a hole for each mounting screw.
•
Install and tighten each mount in location with the
swivel post pointing down.
•
Apply a small amount of lube to the full diameter of the swivel post.
•
Mount the visor assembly on each side and secure with a 8-32x.625 cap screw and #8 high collar
washer. Note: The red knob is closest to the windscreen.

Note: The 8-32 mounting screw is offset and will be on the lower side when installed.
•
•
Using the hex keys, adjust the tensions so the motion is smooth but tight.
o
Motion to the side window is controlled with the cap screw in the
back of the block.
o
Motion to rotate the visor to the overhead is controlled by the
socket head cap screw in the side of the block.
o
Third axis tension, if equipped, is controlled by the #10-32 nylock
socket head cap screw as shown.
The visors will extend in the slides and should move far enough to the rear to cover the entire face.
Tension can be adjusted with the red thumb knob.
Note: The red knob will be towards the windscreen.
•
Your visors can be stowed overhead in several different positions as indicated right.
•
Because of different pilot heights and seat positions the stowage position will vary for different pilots.
On the copilot’s side a forward stowage position is recommended to keep clear of the doorway when
open.
