Talking about the clamp in the pic GTs58 posted above. Its spring metal with a bluing finnish. Used to have a plastic coating with that round bump which has since disintegrated. Its around the tube. (down tube?)
I recognized bike in picture above is mine so I checked since the fork is currently off. Looked like washers at first. Distance between nut and bolt mating surfaces is 3 & 31/32, After loosening things up I could see no washers but the area where the nu and bolt clamp is built up a bit. At first...
Understand exactly. The "cup" on top comes down on to the bearing ring as the underside of the initial adjusting nut "with cup"which in my case is a round, knurled nut.
I ordered those bearings (73 & 2557). I think the bearings that were in this bike were the wrong ones that someone put in. The ones I took out were identical and had 17 balls each which I measured as a "worn" 5/32. I could find no sets with 17 balls anywhere. The ones John recomended were 16 and...
Thank you, I'll search using those numbers. I took pictures of how the bearing were installed before I removed them. Can't find them right now but I checked anyway and will install like in the picture with balls rotating on race and cup. I see what you mean about the bottom bearing. Looks like...
I'm greasing up my old Schwinn which I never did back in this thread. https://thecabe.com/forum/threads/taking-schwinn-out-of-mothballs.140145/ Does anyone know of a vendor who sells head set bearings for this bike. The top one was toasted when I took it apart. It has 17 caged balls the size...
Hi all, I have a 79 spitfire 5 that I need a chain for. Looking online I see 1/2 inch x 3/32 and 1/2 inch x 1/8. Does anyone know the correct guage chain?
Not since the last post. I put it together without the fenders when I went on vacation in Oct. and when I got back the holidays and other ongoing projects got in the way. Christmas stuff is now all put up and I'm starting to work on things again. Its still a little cold here in socal so I'm...
That black paint on the seat has been soaked for over 10 hours with no real degradation. I'm not ready to stick the frame in a bath though until I test it on something else. The mixture I used was pretty weak.
Some of the readings I've done state that phosphoric acid unlike muriatic acid which is basically industrial grade hydrochloric acid does not mitigate rust by a corrosive process that continues after the rust is gone. Instead it contains whatever traces of rust are still there. It must be...
I think it will be good for the seat. It won't require wiping down or reapplying as frequently as the less viscous break-free. I put it on a corner of the seat just to see how it looked. Found the original padding for the seat too.
I forgot about this stuff. My brother turned me on to this product a couple years ago. I use it for protecting the underside of cars and other corrosion prone areas on anything metal. I think it will be better than Break- Free and it is just as easily removable. I'm going to rub it on the...
Now the problem becomes what to do to keep stuff from rusting again. I can see why some folks clear the parts but I'm not going to do that. car wax may protect some parts but that seat and chain guard I'll have to coat with some type of preservative and wipe it down frequently. I used to used a...
Here’s some pics of my progress so far. I reviewed all the posts concerning rust removal and decided to go with what I had on hand and have been using for auto maintenance and restoration over the years. It’s basically phosphoric acid. I dilute it three parts water to one part phosphoric as a...
Thanks, I never noticed the seat rail. I'm guessing I can slide that seat back a bit to give more leg room? I was wondering about the plate too. I was thinking maybe Pomona but couldn't find a listing on the web. I'll have to ask my buddy exactly where it came from. I won't paint it even though...
I’ve had this old Schwinn for several years and finally decided to do something with it. It’s original paint but a 25 footer at best. I plan to just clean it up and put some wax on it along with greasing everything and straightening out the fenders. I’ll also recover the seat, get some grips and...
