I recently needed to replace a Attwood/Excel flip/crank out window pane in a 2005 Winnebago Journey due to a broken seal and collecting water.
The coach is outside of Winnebago warranty but the windows are still under Attwoods 2 year warranty. I contacted Attwood Customer Care (260-463-2116, x510) and once we got the part numbers figured out they manufactured a replacement and shipped via UPS Ground free of charge. It took only two weeks for me to receive the new window pane.
Phyically replacing the window pane was reasonably simple but with a couple of potential gotcha's. Since the process applies at least to Attwood/Excel windows for lots of different motorhomes I thought it worthwhile to document a usable process for a larger audience.
DISCLAIMER: Read through the steps completely first before deciding to attempt this yourself. I am in no way responsible for any injuries or damage incurred by others following the procedure documented below or any variation therein.
<UL TYPE=SQUARE> <LI>Get a ladder tall enough to safely reach the top of the window on the outside and and also a T15 Torx screwdriver.
<LI>The outside weatherstipping at the hinge is the main thing that keeps the flip window locked in the frame once the crank is removed. For safety I chose to remove the weatherstripping in a later step.
<LI>Go inside and crank the window all the way out and, using the Torx screwdriver, unscrew the the crank handle and remove it.
<LI>Now remove the screen.
<LI>Unscrew the crank mechanism from the frame (two screws) and carefully lift the mechanism over the top of the mount while pushing out.
DO NOT PUSH THE WINDOW ANY FURTHER OUT THAN WHAT IS NECESSARY FOR THE CRANK TO CLEAR THE FRAME. IF YOU PUSH TOO FAR OUT YOU WILL BIND THE TOP OF THE WINDOW IN THE WEATHERSTRIPPING. IF THIS OCCURS THE WINDOW WILL BE STUCK OPEN AND ITS WEIGHT COULD CAUSE DAMAGE TO THE WINDOW FRAME OR CAUSE GLASS TO BREAK. YOU CAN FIX IT BY PULLING UP ON THE WEATHERSTRIPPING FROM THE OUTSIDE WHILE HOLDING THE WINDOW AT 90 DEGREES OR MORE BUT IT MAY DAMAGE THE WEATHERSTRIPPING
<LI>Slide the crank arms sideways off the rail on the bottom of the window.
<LI>Climb up on the ladder outside and carefully peel back left to right the weatherstripping over the hinge area. Clean and Armor All the weatherstripping for re-installation later.
<LI>From outside on the ladder open/lift the window up from the edge until horizontal to the ground (90 degrees to the coach). Then lift up slightly and push in. The top of the window should disengage from the frame easily NOTE: THE WINDOW IS HEAVY AND AWKWARE. PREPARE TO HANDLE IT ACCORDINGLY.
<LI>Reverse the above steps to install the new window pane.[/list]After all is said and done it's as good as new.
