Ugly Betty
photo postingThere's something going on with photo posting system, I can't download pics in normal manner either and have noticed several others saying they were having the same problem...apparently pasting in urls from photo sharing sites still works (?) Administrator???

Current restoration: 1962 CB77
http://www.flickr.com/photos/1962_cb77_restore/ When I pulled the rotor I didn't like the looks of the starter clutch outer--the steel shell was badly cracked and pieces of it had broken away and disappeared somewhere.
Only one spring looked close enough to spec, two of the rollers were slightly under spec and the cups didn't all look the same so I decided to replace everything. I taped up the rotor so that I could use the Dremel to grind away the peened sections of the bolts without the filings sticking to the rotor. After a few taps with the impact wrench the outer came off and I could see why the clutch was temperamental. It was in two pieces! I don't know why it would have broken like that, but it was for sure not usable and likely to grenade at some point. The new outer did not have the peening groove machined into it so I had to do some grinding with the Dremel before bolting it on. A few taps with the chisel should prevent those bolts from working loose. Now, with rotor and stator re-installed I can get on to replacing the timing chain and advancer springs. I took the cams out to replace the worn advancer sprocket and after spinning the bearings and listening/feeling them, I decided the two outside cam bearings were iffy, so all four will be replaced.
The photo shows a groove in the head where the right outside bearing goes. There is no such groove on the left side and I can't recall see any photos that show such a groove. I'm wondering if this is original--I don't think so, judging by the uneven, almost crude machining. Has anyone else seen this? Are there any guesses as to its purpose? If it shouldn't be there, is there a way for me to correct this? It's a New Year, and I'm hoping to put this machine together again soon and enjoy the ride! Wilf I'm wondering about the upper mount hardware for the rear shocks.
On my 1963 frame the mounting studs coming out of the frame have holes at the outside of the studs. This usually indicates a cotter pin and castellated nut combination, yet all the parts fiches I have seen clearly show a 'blind nut' or 'cap nut' or 'acorn nut' (depending on local terminology). I ordered a pair of the nuts from cmsnl and was quite surprised to see how small the outside diameter is on the superceded (94021-100-200S) nuts--a 14mm wrench for a 10mm stud. The small OD (wrench size) of these nuts and the existence of cotter pin holes in the studs has me a bit confused--maybe changes were made along the line somewhere and I just haven't discovered them yet? Well folks, I think now is the bittersweet time to close this restoration log.
I realized a few months ago that my project didn't really qualify as a restoration; nonetheless I have reached my goal of restoring 'Ugly Betty' to what I think approaches her former glory. For me, the reward is being able to ride an almost 50 year old machine brought back from abandonment, to have a measure of pride in her good looks and to sense her response whenever I look at her, fire her up and twist the throttle! The problems over the winter have been, for the most part, resolved. I replaced the advance sprocket, head, timing chain, pistons, and cylinder liners and now Black Beauty idles wonderfully and the oil leaks are gone. All is good. I have to thank all forum members for posing questions and offering answers or suggestions, whether they were specifically related to this project or not--they have all been valuable! I do want to thank LM for his time, informative conversations and parts; and FastFred also, for the parts I needed. All forum members have been a great help to me. Thank-you! It may sound like I'm quitting, but I'm not! I still read all the posts every day and continue to learn. Every now-and-then, when I think I can help, I do so. It's just that now, I can enjoy riding a real beauty! Thanks, Wilf
