loosen the locking nut (5.5 mm)
take a long shafted small flat head screwdriver
and turn the top of the bolt (solinoid side)
thru the top next to hoop
turn it until hammer hoop comes off pad then backup 1/2 turn

OK where is the best place and the fastest place to get cap and does it come with instructions?

The adjustment screw(hex headed, not slotted) & nut are very difficult to get to.
I made a special tool from a screwdriver to fit the Hex head,
turn apx 3 turns to take up the distance/space left by the missing cap.
Removing carrier is still necessary most times,
But some model WW's, I can use that tool thru the lower back of unit
This “trick” applies more stress & noise on all related parts,
As the Cap provides a little Cushion of the Impact

I can take a fine pointed wooden rod and pull the front of the solenoid back and the unit types fine! I'm just unsure of how to adjust the nut and set screw. I assume the front I am pulling is considered the "Cap". I have worked on a lot of typewriter including wheelwriters but never had to do a print hammer. My service manual only show electronic repairs to the  print hammer.  Thanks for your patients!

If there is no movement of the solenoid plunger, why? Adjusting or a new cap will not help. The plunger could be so gummy that it does not move. You can follow Rushmaan's instructions and remove the solenoid, remove the plunger and clean it and then you should be able to just look at the cap to see if it is OK. If it still does not work it could be a bad solenoid (hardly ever happens) or a board problem.

Can you walk me threw how to adjust nut and set screw on hammer arm to compensate for NO cap?  My problem is there is no movement of the print hammer, thus no print.  Thanks for all your help.

You never said what problem you are trying to correct.  That information would help to decide what repairs you may need.

Remove case
Remove carrier shaft ( twist latch/lock )
Flip carrier & locate access holes for 2 screws holding solenoid
Disconnect wire harness/connection
Either replace cap (or) adjust nut & set screw on Hammer arm to compensate for NO cap
You can also disassemble solenoid & clean & light relube for PM
If you have the right OEM cap,
And your really good,
You can squeeze cap in place, straight down thru the top without any disassembly

I really only need to replace the cap. I have a repair manual but it doesn't show how to access it and replace it. Do you have something you can send me to walk me through it? Thanks for responding to my post!

Why are you replacing the hammer?  Most times you only need to replace the cap on the solenoid if it is not printing.
