Coaster Brake Overhaul Question
So im in the process of disassembling my first coaster brake. Ive repacked other hubs and even a sturmey archer hub on my 1979 raleigh sport. For some odd reason I was afraid to take a coaster hit apart. So after watching a lot of videos and looking reading information I decided to attempt it.
Disassembly was fairly straightforward, but I have a question on the arm section I kept seeing it broken down to just the axle. Does it have to be taken apart? or can i just clean it and the bearings and adjust from the drive side?
In the park tool break down it says to disassemble the brake arm.
This is the portion I am speaking off.
Here are all the pieces laid out when I first disassembled the hub.

There's no need to take the arm off unless you're replacing the axle.
However, just so you get it, the brake arm is keyed to the cone, so the static brake part is kept from turning when the brake is applied.
If you gently hold the arm trapped between vise jaws, you can remove the nut and the rest is easy.

Agree that there is no need to remove the brake arm. Nothing is accomplished by removing it.

Check the race under the bearing/cage before reassembly. Look the bearings over good too. Now's the easiest time to replace them if there's an issue.

That looks like a Shimano CB-E110? In my area, kids bikes with full size coaster brake hubs magically appear on the side of the road, most of those are chinese knock offs of CB-E110's. So free parts. Some have genuine shimano hubs.

I've had to do 5-6 of these over the past year and have never removed the arm.

If we are all lucky, this thread may devolve into a Disc Brake versus Coaster Brake thread. If I recall, back in the day I used to lay out some sweet skids with my coaster brake CCM. This obviously shows that the braking capacity was equivalent!

This is a cast off. I was impressed with it's smoothness, adjusted correctly from the factory! and that it had real grease in it.
It's a Dachang hoarded for CB parts. Fully shimano compatible.

Yes it is a Shimano CB-E110!
Good to know I didn’t need to take the arm apart. I did inspect all the pieces and they were in excellent shape. The hub is coming off a Linus womans sloping top tube bike that didn’t get ridden much. I bought this for my daughter to ride around the neighborhood.
I ended up putting it back together and it worked perfectly. I took it down the road to make sure it was ok before handing it off to my daughter.
Thank you all for the help and making my mind at ease and not second guessing myself.
