You can&#39;t really take those apart.

It was taken less than a mile and on very flat pavement. The chain will occasionaly go slack and pull the derailer arms forward followed by a snapping back of the chain, all while coasting. I have ordered the freewheel remover tool in order to inspect it. I suspect it is a deffective item.

He was convinced by his little buddy to take the coaster brake &quot;off&quot;, and though I said &quot;don&#39;t do it&quot;, they did. So here I sit, looking at your site, understanding, FINALLY, that the job is nearly as difficult as it looks. They managed to get the entire axle and bearing set loose...and I think the pawl is out of place...I&#39;m gonna give it another shot, but I think a trip to the local cycle shop is in my immediate future. I have bookmarked your site, and will be coming back!Don Schaeferhttp://www.facebook.com/donald.schaefernoreply@blogger.comtag:blogger.com,1999:blog-31040015.post-91098184400956066552010-08-27T23:56:02.376-04:002010-08-27T23:56:02.376-04:00If he pedals backwards and the bike goes backwards as well, it means it was make to work that way.

I found out that the old bearings have become oval shaped - so I was not able to put it all back together without play in the axle.

If you have redone this a few times, it might be that you are using dirty rags. Axle grease is fine. I actually do a 50/50 mix of cheap axle grease and Teflon grease for my rides. Don&#39;t give up, you&#39;re doing fine.<br /><br />Gerry :)Geraldhttp://www.blogger.com/profile/08141103514683766293noreply@blogger.comtag:blogger.com,1999:blog-31040015.post-67330226308859804962009-08-12T00:16:17.352-04:002009-08-12T00:16:17.352-04:00Hi Gerry,<br /><br />Thanks a million for the advice. I&#39;ve been working away at the Raleigh now for almost two months, what a saga!! Everything that could have gone wrong did. <br /><br />The steel punches did not get the cotter pin out, and then I broke two HSS bits on it. After more waiting for the postman I got cobalt steel bits and finally got the devil out.<br /><br />I&#39;ve gotten the axle out and cleaned the bottom bracket as well as I know how, with an old rag and so on. There is wear on the axle and the bearing cup but no pits, so I&#39;ve replaced the bearings and re-greased. <br /><br />Here&#39;s the problem, just like my wheels that I re-did, the axle is a bit crunchy when turned. Even after cleaning and doing everything again. Plus the crank-side bearing cup is seized solidly to the frame and I can&#39;t shift it. Guy at the bike shop said I would have to be welded out (I didn&#39;t understand that part) so I smoothed down as best I could from the far side. Will this wear very unevenly from now on and create a lot of wobble? Also I have tried 11 (1/4&quot;) bearings which is the max that will fit, and 10 bearings and each set-up seems to be equally &#39;crunchy&#39;. <br />Before I started the whole lot by the way there was no wobble in the crank, I took it apart to be a completeist.<br /><br />So anyway bike is still upside down and some worrying green mold has appeared on the underside of the leather saddle, the poor girl needs to get out. <br /> <br />Also on the grease side of things I&#39;m using an ancient tin of Esso multi-purpose, or as my father calls it &#39;axle-grease&#39;. The bike shop has stuff it calls &#39;water-proof grease&#39; but it looks the exact same. Any prompters or am I alright? <br /><br />Slán agus beannacht from Ireland, míle buíochas (a thousand thanks)<br /><br /><br />P.S. The bike-shop even sold me 9mm (continental type) cotter pins instead of 9.5mm(3/8&quot;)!! and I was crystal clear with him. So now another wait for the postman from ebay.Tristramhttp://www.blogger.com/profile/12173944933261526836noreply@blogger.comtag:blogger.com,1999:blog-31040015.post-42149385961534923372009-06-07T16:42:32.614-04:002009-06-07T16:42:32.614-04:00If the bearing cones have wear on them, it is normal if there are no pits and the wear, or &quot;trace&quot;, is even, you can keep them. If you hear crunching, it might just be dust that got in there while you were re-assembling the unit. Take it apart again and clean it properly. It doesn&#39;t take much to sound awful! To take apart that coaster freewheel, you&#39;re out of luck. That part is my Kryptonite and commits suicide every time I try to service one.<br /><br />Good luck<br /><br />Gerry :)Geraldhttp://www.blogger.com/profile/08141103514683766293noreply@blogger.comtag:blogger.com,1999:blog-31040015.post-33759077126608023382009-05-30T23:41:12.093-04:002009-05-30T23:41:12.093-04:00Hi Gerry,<br /><br />Great blog. Can I ask if you have any advice on fixing vintage bikes? I got an old one speed Raleigh Roadster that I'm doing up, but wondering whether I should replace the cones (they do have wear), as well as the bearings. <br /><br />I cleaned out the hub etc. and put in new bearings and left a bit of space but when I turn it with my hands it's a bit crunchy.<br />It still has Sturmey-Archer rims etc. and from a cost viewpoint I'd like to keep as many original parts as possible.<br /><br />Also how do you get off and clean the free-wheel device?? I'm also waiting for a punch to arrive so I get out a seized cotter pin. It has to be done though as the other side had rusty water as lubricant.<br /><br />Sadly my local bike shop (in Galway, Ireland) aren't too interested, and advice is hard to come by.<br /><br />Kind RegardsTristramhttp://www.blogger.com/profile/12173944933261526836noreply@blogger.comtag:blogger.com,1999:blog-31040015.post-34883908351026076602008-10-13T18:49:00.000-04:002008-10-13T18:49:00.000-04:00Hey Bobby,<BR/><BR/>If your hubs have loose bearings, this makes a lot of sense. If you look at a hub with crown mounted bearings, they are not mounted snug, but they do have a certain distance between each other. Go for 10 and you should be good.<BR/><BR/>Gerry :)Gerry Lauzonhttp://www.blogger.com/profile/06895691996292579014noreply@blogger.comtag:blogger.com,1999:blog-31040015.post-43852853829352089252008-10-13T15:59:00.000-04:002008-10-13T15:59:00.000-04:00Gerry,<BR/>I could feel some bearing roughness in my front wheel on my mountain bike. I disassembled the axle and found the race on one side was bad. The good side had 10 ball bearings, while the damaged side had 11. Rough calculations of the race shows that 11.6 bearings will fit. A site on the internet said that you should use 1 less than will easily fit. This would explain why the side with 10 was ok and the one with 11 failed. When I get the new race, I want to fix it right.

If that is not the case and the freewheel turns without moving the wheel forward, the mechanism is shot and it needs to be replaced.<BR/><BR/>GerryGerry Lauzonhttp://www.blogger.com/profile/06895691996292579014noreply@blogger.com
