It doesn't look to me like you have the correct TO shaft for the late-style bearing. The arms on that are quite different from the earlier style. Look at where the cutouts in the shaft arms are in the photo Glenn posted. |
We have the correct TO shaft as it is the only one that fits the bell housing we have. The later model TO shafts are thicker and do not fit into the openings. I appreciate the thought though. |

It is on the arm straight to begin with then it turns when the clutch is depressed. I really wish I could figure out how to upload the 3 second video that shows it turning. |
Post the video on YouTube and then put a link here.

There are three types of TO bearing shafts. Two of them will fit your early style transmission.
'70-earlier
'71-'72
'72-later (larger diameter shaft)
The '70-earlier shaft is the only one that uses the older style TO bearing.
The '70-earlier and the '71-'72 shafts are interchangeable and will fit into the same transmission cases. Since you upgraded from an early type TO bearing you should have replaced the '70-earlier shaft with the '71-'72 shaft which will fit into the early transmission case but use the later type TO bearing.
The later two shafts use the later type TO bearings. You should think of the '71-'72 shaft as a transition shaft.
This pic from glutamodo shows the two types of TO bearings and how they mount to the shaft arms. You can see the round cylinders sticking out the sides of the early TO bearings fit into the cut outs in the arms.
Later TO bearings don't have these cut outs.
Here is a close up pic showing the small cut outs on the front side of the arms that the TO bearing clips snap into. The TO bearing rides on a curved surface on the arms.
Installed correctly, the clips should prevent the TO bearing from riding up the arms.

I have a problem with a squealing noise when I idle and press the clutch pedal. No centering ring on the pressure plate. Have a late style TOB with the sleeve. Any suggestions would be appreciated. TIA.

That's typically an issue with the throwout bearing.

Did not. Probably the problem?

New bearing. Should I purchase a different brand?

The pilot bearing turns on the transmission shaft whether the clutch pedal is pushed down or not.

I noticed at the center of the pressure plate where the ring would go has uneven wear. Shining in some areas and not on other areas. I created this when I took off the center ring on the pressure plate. I did not remove it from the inner side where the spring holds it. I removed it from the outside. I believe that’s the issue.
Should I try and even them out or just purchase a new pressure plate?

Could your noise be coming from the engine and not the clutch?
Go around to the crank pulley end of the engine and pull/push on the pulley. If the crank end play is correct there should be no noticeable movement in the crank pulley. The 0.004" end play should be unnoticeable to the naked eye.
My old engine had enough end play that you could see the pulley movement and the engine rpms would change when you stepped in the clutch.

I would like to thank everyone for your support. I was low on gear oil(1bottle until it leaked out of the filler ). Noise went away drastically. I’m going to cycle it on all gears this weekend. Still there but it went down on first and second. Tried it on 3rd and it was barely any sound of the squealing. Thanks again.

I have a project that won't run fast or far. Mostly around the ranch. So I have a '74 beetle pan/transaxle and a '62 1200 motor. Thinking of buying a '74 flywheel and a clutch kit and starter. Is there something else I need to contend with when mating this motor to the '74 uniy. Read something about that there is difference in rear main seals. Is there something I will have to do to mount this motor? Maybe change out the pilot bushing? Thanks for any help you can provide me. I do some mechanic work, but don't have experience with VW's so please be specific and patient with me

Flywheel issue.
A 1962 40HP engine has a different shape to the end of the crankshaft. These used a paper or metal gasket around the dowel pins. Late in model year 1966 VW changed to a different shape to the end of the crankshaft and a flywheel with a rubber O-ring for sealing. You can't put a later O-ring flywheel onto a "step" crank unless machine work is done.
