9:10 For that part I usually wrap the pull body with a sewing thread, usually two wraps is enough to hold the pulls in place, also I don't apply too much force as the cotton thread can break pretty easily and then can easily insert the ratchet back to freehub body. Finally with gentle pull I can easily remove the thread.
thank you for your video, I have a question i bought an old bicycle of witch i serviced the rearhub its a Campagnol Avanti 8s. the bearings feel smooth and there is no play but the moment the body is engaged you sometimes hear a grinding noise. Its not in every position. If i turn the cassette you dont hear anything and then i turn it a little further and the sound is back. It also appears that its louder when i press down on the cassette with my hand. Do you have any idear what that could be?
Does the cassette move about? From side to side that is. Without myself being infront of the wheel, my guess is that the body for the cassette is worn. I believe they have pawls at the back, maybe they are worn. Remove and check, maybe the springs are seized eventually.
@@atboy4342 there is no play in the cassette at all. I serviced the hub completely the pawls and springs are free. The body also sounds nice and smooth it engages properly. I think the bearings of the body might be worn. The sound gets worse the more things i add to it. For example without the cassette there is no noise. Then with cassette there is noise in certain positions. And then when i put the wheel in the frame the noise gets even worse. I could make a video for you that you can hear it. Normally id replace a part and try things out but with vintage Campagnolo its not easy to find new.
@@jumpforce93 If you want. I’d agree though ball bearings are potentially the issue. By adding things and installing onto the frame, it’s creating pressure/load emphasizing the issue - Cup/cones, incidentally if they are pitted. Probably be cheaper to swap out the hub with another used campy. Does the body have bearings? Don’t remember mine having any, rather it seats onto the spindle (could be the spindle?)
@@atboy4342 the cones and the axle are free of wear. And the balls look like new. The body has 2 industrial bearings. The thing is the hub runs smooth untill it turns on the body bearings. When it runs forward its using the hub ballbearings and you hear nothing but the moment the body is engaged you hear a strange noise. thats when the body industrial bearings are used to run. So by that logic i assume those are bad but i have no expirience with Campagnolo and i thought mabye i made a mistake and its a matter of adjusting
No, older Campagnolo groups or parts are (nearly never) never branded for some reason. I looked at a 8 speed mirage hub from the same period, and they appear identical.

Then it can only be that, good luck finding a replacement@@jumpforce93
Great video! I have mirage 8 speed hub, looks identical. Are there any indicators if it's mirage, athena, etc.
