Axis air flow improvements

Axis air flow improvements, part one.

We are new to the Axis 24.1 and decided to upgrade the airflow in the cabin.
Part one - Coach windows.

First order was to increase the amount of air in the coach by modifying the windows a bit. I did this in our Holiday Rambler Admiral we had for 6 years before the Axis with the same type of windows increasing the airflow substantially, and we never had a problem with these windows after the modification.

Tools needed are pretty simple – a Dremel tool with a reinforced circular cut-off blade, a hand pop riveter/rivet gun, pair of metal snips, a length of aluminum flat bar (I believe it was 1/16 x ˝ and maybe 4-6 feet long) and drill.

On the window frame, cut the pop side of the rivets (window side) off and remove the window’s hand crank and spacer bars attached to the window channel. Depending upon the window, there may be a plastic spacer that prevents the spacer bars from opening the window any wider. You might remove that plastic spacer and cut it down to an inch or so in length. That may allow the window to open wide enough to suit your purpose. If this is good, just reinstall the window hand crank with pop rivets and you are done. This worked on one of my 7 windows in the Axis and worked on several windows in my Admiral).

Most of my windows had no spacer or a small spacer, so a little more work was needed. Measure the length it would take to open the window as if the bar on the window opener were long enough from the little wheel that goes into the window channel to the thicker window opener leg. This would be the total window length from wheel to hand crank leg length. Measure twice, cut once!

There is a thin metal bar welded to the thicker window opener leg. I found that by cutting this thin metal bar about halfway and then drilling two holes for rivets on both cut ends. Then drill holes in the aluminum flat bar cut to length and use the pop rivets to join the bars together. The aluminum flat bar is a bit wider than the OEM thin metal bar, so I rounded the corners of the cut aluminum bar with the Dremel grinding tool. Also found that if you use the flat side of the rivet underneath the thin metal bars you are attaching together, they clear the window frame nicely on the reinstall.

Now that you have both sides of the window opener extended and completed, insert the opener wheel back in the window channel. Do the same to the other side. Reinstall the window hand crank onto the inside frame of the window, pop rivet it to that frame and you are done! I work slowly so it took me maybe 30 minutes per window after the first window and had a sense of what I was doing.

To complete the job, I took some gloss black paint, touched up the inside Coach rivets and painted the newly extended flat metal bars and rivets as well. The attached picture shows the before and after of the RUV slide out.

Takes a little time, but the increased airflow in the coach was well worth the effort!

No "Attachments" at all on that post nor any in-line images. Did you click the "Upload" button after selecting the picture attachments?

No.

Let's clear up terminology:

You can "Insert" images that are already hosted on a publically available site. I am inserting an image from Amazon:



You can attach images and other files to the post using the "Attach" feature. They will show up at the end of a post. I am now attaching and image.

I have also attached a PDF file.

Are you using a PC browser, the Forum APP on a phone or a browser on a phone?

I have been attaching images for years on these forums by using the paper clip icon. You have to first get to the Advanced display version if you are in the Quick Reply version by clicking on the Go Advanced icon at the bottom of the message.

But I have never used Insert. Could you explain more?

To begin with, in edit mode you must go advanced to attach photos.

The is a sticky in the admin section that lists the procedures.
