WINDOW NO. 2 (PILOT'S SLIDING WINDOW) - ADJUSTMENT/TEST
1. Window No. 2 (Pilots' Sliding Window) Adjustment
A. Prepare for Adjustment
(1)
With the window in closed and lock position determine the adjustments required to obtain proper positioning of the window, as follows:
(a)
Determine adjustment required to center window in fore and aft position for a gap of
0.06 +0.03 inch between forward outer surface of window and outer skin.
(b)
Determining that window closing force does not exceed 45 +15 pounds.
(2)
Unlatch window and check for smooth operation.
(3)
Remove window No. 2 from track and place on a suitable support (Ref Window No. 2 [Pilots' Sliding Window] - Removal/Installation).
B. Adjust Window (Fig. 501)
(1) Adjust vertical position of window.
NOTE: Minor vertical adjustments can be made by varying number of shim washers between mechanism bellcranks and glide bearings as required to obtain smooth operation of window.
(a)
Remove special bolt from through glide track roller.
(b)
Remove or add shim washers as required.
NOTE: If shim washer is removed from lower glides, one will probably have to be installed at upper glide to maintain original dimensions between glide faces and to prevent window tilt. If adjustment is being made to correct a binding condition, removal of shims from upper glide only will be necessary.
(c)
Install special bolt.
NOTE: Make sure you tighten the lock screw (6) securely.
