You are correct. Since there's no screw, just turn the spout counterclockwise and remove it from the pipe coming through the wall. Depending on the type of spout you're going to install, you might have to cut the threads off the end of the pipe and tighten the spout in place with the screw on the new spout.
You should be able to spread those plastic strips enough to pull the diverter rod out. Cleaning the inside area and pieces might be all you need to do.
That threaded adapter came with the spout. The threads will be standard but the distances could be different with different spouts.

I have the same faucet. Same type of diverter. I took out the diverter per your and others on YouTube instructions. Wanted to see if lime and scale were causing a bad seal. So I put my finger in there.
What came out stumps me. A chunk, like flat thread of metal. Put it together and it still leaked. So I took it apart again. Thats when the second sliver fell out. Two slivers of metal. I thought it was the faucet, but I think what I got were two pieces of solder. It works like new now. I'll see how long it lasts, but it operates smooth and really stops all water from running out the faucet and it all comes out the shower head now. It even unlocks when it's turned off and drains out the water from the faucet. I won't have to remember to push it down now. So better than before. Has this ever happened before?
I thought those pieces were a worn out piece inside, but it seems like they were in there since the install. I attached a pic to this alternate answer.
i recently moved into a new apartment and can't figure out how to use the shower. there is no pull thingy (i think its called a diverter?) to switch water flow from the spout to the showerhead, and I've messed with the handle a bunch (pulling it out, pushing it in, turning it in both directions as far as it will go, etc) but can't seem to figure it out and I'm scared of breaking it if I mess with it too much.
can anyone help? am i missing something obvious? thanks in advance.
It's simple. The upper port of the valve is used to plumb to the shower head. The bottom port is for the tub spout.
The tub spout should have a diverter to direct the water to the shower when desired. That's it.
You have the option to add a transfer valve to add a wand or additional shower head or whatever you desire, but that is an option.
Additionally: "...then cap the other outlet of the tub spout's diverter." ??? There is no other outlet in a tub spout.
"...it does not look like the valve has an integrated transfer valve."
If you are using the 4-port valve for simple tub/shower application, you don't need a transfer valve. Transfer valves are used if you have a more complex setup, e.g. multiple shower heads that you want to control.
"How do I switch between the tub spout and the shower head?"
Order the trim package that comes with a tub spout diverter; the spout has a valve wherein you pull up on a rod/knob to (partially) close a valve, which diverts the flow up to the shower head.
I think you are confused about the transfer valve terminology...
How does it work? The slider rides very loosely. The slider has a recess that captures a rubber "cup" the cup has a hole in it. Why does the slider and cup get pulled against the spout bulkhead rather than be pushed away? Is there a moving part in the rough-in that moves and directs water up to the shower when I pull up the diverter handle.
My spout was letting too much water dribble/leak out when the slider was up and water was diverted up to the shower. My repair was to place an o-ring inside the cup. The spout still dribbles, but much less.
My tap in the bathroom has a pull up type diverter to change the water flow between filling the bath or going through the shower head. Recently, when I try to change from bath to shower, it does not do it completely, and I'd say half the water still goes through the bath nozzle, the other half going through the shower head.
I do not have any experience with this, but I'm assuming either the diverter valve is worn out failing, or it is the spring?
My question is, what would be the most likely culprit? The tap I have is a GROHE CONCETTO TWO-HANDLED BATH/SHOWER MIXER ½″.
I also can't seem to get the bottom of the tap off. There is a ring at the bottom that I just cannot remove, no matter what I try.
Thank you in advance!
