Meh, I feel like I haven't gotten much done in a while.
Had some family issues to attend to that pushed back garage time.

The hub did get to me.
Got delayed at the post office. I think some times they try and see if they can kick stuff all the way to the destination....
Emailed to ask where the hell it was, and poof it was found and dropped off a day latter.

Still need to get the money to you.

Hope that I can mount it up tonight.

Thanks again for the help.

Hi
On my Seeley the internal axle adjusters take a standard M8 stud. I may have mentioned before that the axle hole is offset to one end.

cheers
Thomas

Snuck away for some garage time last night.
I tried to mess with the hub that supposed to have been on the Seeley at some point. I think that it is a CB550 hub, but not 100% sure.

Idea was to take the axle reducer, brake drum and sprocket carrier off of the hub and place them on the CB750 wheel that I have in the frame now. If you remember I found that all of the CB750 parts did not fit as they were to wide for the swingarm. Also the sprocket carrier pushed the wheel assembly off center to the right.

Well I couldn’t get the retaining ring off of the hub to remove the sprocket carrier. What a pain. Yes I know it is reversed thread, but is taking one hell of a pounding to remove. Not sure what Honda was trying to do by using these parts. And even at that point I don’t see how all this jazz will work with the CB750 wheels.
So after fighting the hub for a while I decided to just mount the hub in the frame. And low and behold…..more issues. Now the unit is slightly to narrow! Maybe I am not looking at it right. I didn’t tighten everything down, it just seemed like more space to take up then normal.

Here is the picture of the original parts that I had to work with. You can see the gap.

And another one of the spacers I had around.

The OEM CB750 one. After thinking about things and looking at the pictures again, I might have things out of order?
The one on the axle in the above picture normally goes into the sprocket carrier side right?
Will have to take another look.
Honestly buy the end of the night it was getting late and I was rather frustrated as this bike seemed to be fighting me at every turn.

No, that one goes on the brake side. The one with the step on the OD goes on the sprocket side.

I think some folks may have used the 500 hub as it is a bit lighter..if they were weight conscious.

That is probably the case.
Actually makes a lot of sense on a bike like this.

Other thing is that the 550 sprocket carrier is a fair bit narrower then the 750, allowing the wheel assembly to be centered properly.
Will need to see what it takes to use the 550 carrier on a 750 wheel.
The drums are ever so slightly different in diameter. Unsure what the impact will be.

Like I said, I was fairly frustrated by the end of the day last time so when I am back in the shop tomorrow I will take a deep breath and try and sort this debacle better.

Howdy,
Which 750 sprocket carrier are you using....the long one or the short one?

Steve

jaguar · « **Reply #132 on:** March 12, 2015, 01:12:23 PM »

The one that came on my 1974 parts bike.
I did not know that there was a difference in any of the rear wheel parts 1969-1976 K bikes.
Please tell me more.

Swoop · « **Reply #133 on:** March 12, 2015, 01:32:39 PM »

There are two types/offsets .....I think the longer one came on the later bikes.....this would push your wheel to the right.
Yours may have been switched along the way......or maybe not, but best to check.
On the short one.....from inside of rear sprocket to outer face of alloy hub (closest to wheel hub) is approx. 13/16".....if that makes sense.

the F2 F3 and K7 K8 have a 10mm wider sprocket carrier, to suit the 10mm wider out put shaft in the later engines, it doesn't push the wheel to the right, its the actual carrier that is wider, I'm using a K8 carrier and 10mm offset front sprocket to fit a wider wheel tire combo on one of my bikes.....

What I meant was that if he tries to line up the sprockets...it would push the wheel to the right.

It would but that would involve making specific spacers, if a late model carrier is used without touching anything else, it would put the sprocket to the left by 10 mm...

jaguar · « **Reply #138 on:** March 12, 2015, 05:55:31 PM »

You guys are funny.
Ill get some pictures of the junk I have to work with tomorrow while I am in the shop.
Should be able to figure it out from there.

Right now the whole wheel is to far to the right, have not looked at sprocket location at all yet.

And if I get frustrated again ill just jump on one of these and take it out on the snow covered yard.

Get some 750/500 spacers, you should be able to find something stock that will work...

scottly · « **Reply #140 on:** March 12, 2015, 06:58:59 PM »

Guys, remember that the Seeley was designed to accept the stock 750 rear wheel. Jag, I suspect you need to remove the stock 750 spacer on the sprocket carrier; the Seeley chain side spacer might replace it?

Yes I know Scott, years ago i had a rear flat on my 750, i borrowed my mates 500 wheel till i could get the tire fixed, just can't remember what spacers i used at the time....

scottly · « **Reply #142 on:** March 12, 2015, 07:30:37 PM »

Jag, can you post another pic of the chain side Seeley spacer? It looked like there is a burr on the edge of the step, as well as rings where the seal in the carrier ran.

jaguar · « **Reply #143 on:** March 13, 2015, 03:42:00 AM »

I'll be back at it today after I leave the office.
Should have a fresh mind to tackle it.
Have a few random spacers around an another rear hub coming over too.

jaguar · « **Reply #144 on:** March 13, 2015, 03:43:17 AM »

How tight or loose should all of the stuff fit into the swingarm?
I don't feel I should have to spread or collapse the arm very much at all,but maybe I am expecting to much?

scottly · « **Reply #145 on:** March 13, 2015, 06:27:52 PM »

You shouldn't have to spread or collapse the arm very much at all. With the proper spacing, the fit is very close, and if the parts aren't perfectly aligned it can bind a bit, but a small amount of wiggling and jiggling and holding your tongue just right will line things up.

Try fitting a stock 750 wheel; it should fit right up with the Seeley spacers you have.

754 · « **Reply #146 on:** March 13, 2015, 07:03:02 PM »

As far as I know, the 500 hub is same diameter, uses same spokesman 750.. But thehub is narrower, thus lighter.
And me not being the roadrace type..not sure but with better than stock front brakes, many actually. Require less rear brake..

Seeley 21 Rear Axle Spacers Solved.

I just love when you leave a project sit and when you come back to it everything magically falls into place! Unsure exactly what I was doing wrong, but I am now 90% sure the rear axle spacer issue I was having is worked out.

To just go back for a second, here is the CB550 hub that allegedly was on the frame before. Still cant make it work perfectly though, but that doesn’t really matter as I plan to run Cb750 wheels anyway. The important bit was that I got he correct axle reducer out of the hub.

I was unable to get the “lock nut” off of this hub so that the sprocket carrier could be removed. Lucky a friend from MA is going to mail me one next week. I would have had it yesterday, but he literally packed a hedgehog in his car instead of the hub…..

What I was doing last time was leaving the sprocket carrier on and leaving the brake drum off. I had assumed that it didn’t matter. Well the carrier that I was using looks to be one of the “taller” ones, so it pushed the wheel assembly to far to the left.
Bad angle, but can kind of see it.

But when I assemble things with the stock CB750 brake plate and the Seeley spacer the wheel is right in the center. At this point I have not measured to the tenth of a millimeter, but by eye it is super close.

Its almost like all this junk was meant to fit together….
I will have to get a better measurement to know for sure, but for now I am just happy to be moving in the correct direction.
Was using the Lester for mock up for two reasons, first that’s the wheel I want to run, and second the stock wheel with a tire is fairly heavy to bolt on and off a million times.
With some great tips from members I learned that there are two Honda OEM sprocket carriers. One tall and one short. Never knew that. Seems that I had the taller of the two, and that was not going to jive with the spacers that I already had. Odd that it was on a 74 CB750, but over the years who knows what parts got swapped onto bikes.

If you take a look at Cycle Exchange they have a nice write up on the differences.
http://www.cyclexchange.net/Chain%20Sprocket%20Page.htm

So I guess I am now on the hunt for a shorter sprocket carrier. Hope I don’t run into issues with chain alignment or anything else with the rear once I have one in hand…

Why do you say hub was allegedly on your frame? The original CL ad had it all together only later was it separated and you seen the wheels and forks when you picked up the frame and passed on them.

jaguar · « **Reply #149 on:** March 14, 2015, 02:42:54 PM »

I mostly meant that in jest.
I have seen that it was mounted up with these parts. More talking about how it was last used.
Have found stuff "mocked up" with parts, but they were not what was actually used.
Like anything, it was built up a million times so who really knows what was what.
It's just a talking point, not a huge deal.
