Well, unless someone wants to wait 5 days to be approved at SOHC4, don't bother. It's an embarrassment to forums, we approve new members in minutes, usually less than 5 to 10 minutes and often under 5. The only ones who have to wait are those who join between typically 3 AM and 8 AM EDT when both Jim and I are asleep, and they get handled within a half hour of when I get up.
I believe I have a seal.. I bought this oil seal kit from 4into1. There is one labeled “Points Seal”.

That's it, good job.I believe I have a seal.. I bought this oil seal kit from 4into1. There is one labeled “Points Seal”.
Engine Oil Seal Kit - Honda CB450K CL450K CB500T
Engine oil seal set for the Honda CB/CL/450 DOHC twins. This oil seal set is great because all of the seals are individually bagged and tagged with their dimensions, use the list below to see where each seal was used.
Would any of the other cam bearings need any oil? They are already buttoned up. And would it be a good idea to pump any motor oil onto the cam lobes/followers/etc. before I put the intake/exhaust valve covers back on?
Good that you asked, and I have a solution for you. Before you go that far however, you'll want to adjust the cam chain after you're done with the last cam bearing (leave the plugs out), then adjust all 4 valves on the proper stroke (ask if you're not sure), then at least set the points and static timing with a test light. Start with both points set at .014" when they're open fully, do one set at a time to be sure.
I have developed a whole system now. Lol. First I hand pick, then lightly use a flathead screwdriver, then green scotchbrite, then lightly use a razor, then 0000 steel wool… All with WD40 applied. It’s a good feeling!
Is there a preferred sandpaper grit?
Yes, this would be the second time I have removed it. Kind of strange that it would not want to go back on. I’ll give everyone’s cleaning advice a try.
Pretty cool that Honda made these parts with such exact tolerances, but a small amount of corrosion can create a situation like this. No big deal. Do what LDR said, inside and out.
Would you happen to know what size e-clips go on the posts, that hold the weights? I had one randomly fall off tonight. I replaced my loose ones with some from Ace Hardware, I guess they didn’t fit right. All I would need is a measurement of the post in millimeters I think.
Not off hand. I guess you could use the other for size. Honda doesn't have separate spare parts for these advancers but the tiny circlips and thin washers are important. It's also handy to have a slide caliper on hand to measure these various parts. Digital electric is quick and handy, but so is old school vernier (especially if your eyes are good.
Comparing my old JIS screws to the parts diagrams, everything was out of whack. At least one screw on every component was the wrong size, extremely stripped, or stuck. This was causing headaches and oil leaks too. The new Allen set, with pictures of locations, has been a breath of fresh air.
Though I'm not a big fan, those are small cap-heads - but you didn't confirm: they're no taller than the JIS screws, right? Again, I only have a 2 dimensional view. Pretty sure the typical allen heads like you're using in the outer areas of the bearings are too tall to fit behind the advancer.
Pardon me I misunderstood. I was reading it as comparing the length of screw, not the cap heads. I can check this tonight when I get home.
There's limited clearance behind the advancer, and I know that the standard allen heads are too tall which is why I wondered about the cap-style allens you're using. They look shorter but of course, depth is difficult to be sure of in this medium.
In putting the AAU back together on my CL350K3, I messed up one of the e-clips. These AAU's were purchased assemblies that Honda got from their supplier(s). They never serviced the pieces individually, and the assemblies are NLA. I found the proper size e-clips to be McMaster Carr part number 98543A103. For US $2.85, I now have a lifetime supply of 100 pieces, less the 2 that I have used. They are still available, but inflation has pushed the price to $3.55 for 100 pieces.
Out of curiousity, I searched online for a spare. I have always seen these assembly units for $100+. I couldn’t help but buy this when I saw the price, even if it’s average condition. If my eyes serve me right, it looks like that center cylinder is installed 180 degrees backwards.
Well hopefully he ships it in something other than home insulation. Yeah, the breaker cam lobe does appear to be 180° off, it's easy to do if you grab that first to remove the advancer unit and the main portion sticks on the shaft and the cam pulls off alone. This is the simple mistake so many make when they don't notice how it was before it came off, but the good news is it's a 50/50 chance of getting it right the first time. Which totally means I'll pick the wrong way first, just like 80% to 90% of the time I plug in a USB device.Out of curiousity, I searched online for a spare.

Once again, I appreciate all of the help. I just got done lightly sanding the camshaft and inner cylinder on the Advancer, then applied some oil. Slid right on.
I can’t help but ask. Where are the main parts to oil on the Advancer assembly? Use motor oil or 3-in-1?
the weight pivots and the points cam sleeve on it's hollow shaft. Engine oil, a few drops.
If we knew that the 350s and 450s used the same size e-clip, I would be more than happy to mail you a few of the ones I got from McMaster-Carr. If you want to PM me your mailing address, I can send you some and then we will know if they fit both models. I've had a pair of them on my CL350K3 for thousands of miles with no problems. On the other hand, maybe you don't need any more clips if you have another complete advance unit on its way to you.

I am reminded of a time when a guy was desperate to get the two little screws that hold a Honda speedometer face in place. He had searched everywhere and couldn't find them in the right diameter and thread pitch. I tore apart an old junk speedo that I had and mailed the screws to him in a regular business letter envelope. When he got the envelope, it had two little holes in the paper and no screws left inside. The screws were probably left jamming up the works at the US postal service sorting center I guess that was a bad idea.
Poor guy, I bet he was inconsolable. Never underestimate the diabolical destructiveness of the USPS.If we knew that the 350s and 450s used the same size e-clip, I would be more than happy to mail you a few of the ones I got from McMaster-Carr.

Thanks for clarifying that. I have bought from
Chris is absolutely right, now that I think about it I remember the guy I bought that set of transmission shafts and gears from. He runs a FB group that I got booted from for telling the truth.
If everything checks out as an OEM setup, then I’ll see about repairing that cut wire or seeing if I can find a new one.The second picture shows what looks like a non-Honda terminal on the ground wire. I looked them up, thinking Honda must have riveted the ground wire to the black bracket the signal mounts on and is retained by the big fender bolt, but it shows a ground wire with a ring terminal (#19). I just don't ever recall seeing Honda use a mount bolt out in the open like that for a ground wire, seems odd.
The way the parts fiche displays them, I'd say just crimp a ring terminal of proper size to the existing wire and bolt it together the way it shows in the fiche. I'm amazed I didn't recall them being that way on my CL450K4 in high school and I put the bike together myself - I bought it in the crate and assembled it at my parents' house. Then again I pulled all the turn signals off it because back then, just as now, I don't care for them on a bike. But that means I would have removed the rear ones because they always came on the bike in the crate, only the front ones had to be assembled. Can't believe I don't remember.
This means that we are all here together learning something new everyday lol. Here soon I’ll be swapping out the hacked up wiring harness, for the one that Brody sent. Maybe I can snag a matching ring terminal off of the old one.
I can't believe how many little details you do remember on all these models from back then.
Yeah I guess, but from my perspective it's crazy (and a little bit discouraging) when something like that comes up that I would normally have given Honda more credit than they deserved for thinking they would never have done it that way, much too simple, and that I wouldn't have recalled it with so many I touched all over the bike during that period. At least I do have a fair amount of stuff still accessible stashed in my coconut.
It is solid as a rock. Lol. It’s so stuck it feels like one solid unit. Time for some WD40 and persuasion
It may help to let that WD40 soak in overnight or to add more a couple of times before you begin persuading it.
