There are many on-line

It's a straight forward process with the correct parts, what are you unclear on?

I will say this, that IF you have NEVER done a woofer repair and you have genuine cone kits you MIGHT want to consider having the work done by a WELL VETTED speaker mechanic

Do not know if you will be able to find a tutorial here that may deal with any possible driver specific idiosyncrasies or not (or if there are any for you to worry over) Mass ring concerns?

And don't use any adhesives that may be packaged in well aged NOS kits :)
(how old are your kits, they may need new foam)

Good luck!

I have brand new Jbl kits and the Moyen is datet well past 2017.

One of the concerns is mass ring. It seems to have small edge and it sinks partially inside of the coil, is this glued with Moyen and only from outside of the ring ? Picture would help.

If you can suggest a online tutorial for 2235/45 with mass ring i would really like to see it.

I spoke too soon, I have found plenty of tutorials for you to view but not for that specific woofer, sorry
I have also spent the past 20 minutes digging here; I am certain you can find it here with some effort
Maybe not a video but surely some photos and text
I tried to help, now I'll let you finish with the research

Can't you see on the old assembly how it was treated? Or were your baskets already hacked with after market parts and a missing mass ring?

Can someone confirm that the Moyen is added only to the outside of the mass ring ? Or is it stuffed between the coil and mass ring also ?

Don't quite understand what you mean by "stuffed" but I use the adhesive as judiciously as possible, just enough to secure the ring well with a clean joint

The glue adds mass as well, no need to overdo it

There is a gap between the coil and mass ring, is this gap supposed to be filled with Moyen.
