Help with headset / Pace RC37

[TDIfurby]

Tried today to (unsuccessfully) install a Cane Creek headset I bought off here. It was sadly missing an inner ring part of the lower bearing so the fork moved around. However, I was more confused about the top part. The top of the headset has this kind of threaded in bolt, which inside has an elastic O-ring in three claws/grips that appear to hold that threaded element in place.

The cane creek headset top has only got a thin bolt in it, not one like my old headet which is about a 20mm or so fitting, which screws into the inner thread.

Any ideas people? Was hoping to get lots done today instead I have gone one step backwards. This is the top of the fork

I'm wondering now if I need to remove that bit, then screw in the new cane creek screw top in to it, once I have attached the stem? Still a bit annoyed about the missing ring that means the headset won't be fitted.

If I am reading your post right it sounds like your new headset uses a standard star fangled nut for installation like these,

Your old one sounds and looks like an FSA Conix or similar, as below,

I would guess you remove the old section from your forks as pictured using the allen bolt inside and install a standard star fangled nut.

. . . . I may be wrong

The old headset is an FSA one yes. You can see it in bits in the photo here.

The shape is funny as the metal insert I do have is angled to sit in the bearing better, but the one I am holding in my hand is vertical inside, so whatever insert goes in it, must be straight with some kind of lip.



The chap who sold me the headset is doing his best to help, so fair play.

The alloy ring looks like the crown race (the bit that slides over the fork steerer resting on the crown at the bottom and contacts with the bearings on the headset)

I am assuming you removed the old crown race from the forks? If not it may be the wrong shape etc.

If you are getting some small lateral movement that may be normal if it is not tightened via the top cap (as you had the wrong fangled nut as mentioned earlier)

Once you have installed the top cap by whichever method tightly there should of course be no movement.

I think . . . .

Having said all that just noticed it is on the top section of the headset. . . . I'm out!

The bearing I am holding in my hand does not sit flush on the fork bar at all, so not sure really. Just seems to be missing something, but I don't know what to be exact. haha

Would anyone have a spare one of those rings my index fingernail is propping up? WIll be 1, 1/8".

Otherwise I may need to put up a piccie of my entire headset split down to see if I have assembled it correctly.... As far as I can see its 2 sets of bearings, 1 in each cap, but only one has one of these centre rings to locate the steerer in the middle.

I have a Cane Creek S-3, there was only one "shim" with it, which takes up the "slack" at the top of the tube, because the "crown race" should sit perfectly in the lower bearing race!

Does this video help?

I think they are RC36 forks too!! RC37 are dual crown! (I think)

 

[TDIfurby]

Hmm, would suggest I have cocked up the install. Reviewing video now. Thanks

Looks like my shim bit needs to go in the top as I have it, but there must be something I am missing on the bottom part. I will have to re-assess how it works. At least I got the cups in fine, although I used copper grease and hammered them in with a small mallet and a cloth to protect the metal.... Not quite the same as on the video.

Still not 100% if my Cane Creek cap can be made to work with the T-I thing left over from my FSA headset, that's lodged in the top of my Pace forks,

OK - having checked again, I am sure I am missing an insert. Check out the pics below. Firstly, cover is on the fork crown fine. Well lodged on. Next, the cups are snugly seated in the frame. But check out the last pic, of the two sets of bearings. Note the one on the left has a thin insert which is perfectly 1 1/8" and this never moves. The other ones has a weird flatter insert, but that does not sit right and nothing is 1 1/8", so there is a wobble... I am sure I need another example of the bearing insert on the left, to go in the bearing on the right. Can anyone help with this?
