I just replaced my frame and I thought I would walk everyone through it since it is kind of a pain in the ****. I am going to skip the dis-assembly part as there are already loads of videos on how to do that. Let's get started shall we?
The first thing you are going to need is to ORDER A NEW TOP COVER when you order your frame. I ordered all my parts from
True Supplier.The old cover is melted on and cannot be reattached to the new frame properly, resulting in a loose fit.
Tools: You will need a Torx driver and plastic pry tool (normally included with the new frame). You will also need a butane soldering iron like the one pictured below.
Ok. Once you have it all apart, there are a few pieces you need to move over from the old frame. The old top cover has to be removed by prying and breaking the bonds (which is ugly) in order to move the mesh screen for the mic over to the new top cover, as well as moving a few sticky foam pads over.
As you can see in this pic, I have marked the important parts with my crappy photoshop skillz.
The blue arrow shows the mesh screen which is stuck to the cover. Gently pry it away and put in on the new top cover. It should stick to the new top cover well enough to hold.
The foam tape strip (highlighted in green) also needs to be moved over. It can carefully be peeled off, but it tends to separate and leave the adhesive on the old cover.
Lastly, I have marked the plastic retaining tabs in red(ish) boxes that you will later have to melt to secure the cover to the new frame.
There is one more foam pad (that hold the mesh grill down) that you have to move to the new frame. I have marked it in this picture.
Once you do all that, fit the new top cover to the new frame. You can see below the little tabs you are going to have to melt next.
Here is a pic of the little tabs melted down with the soldering iron.
After that, I added a tiny bit of crazy glue to make it stronger.
Then reassemble everything and you are done. Took me about 15 minutes.
