I just dug through some of my stuff here I found an old (as in NOS) bearing box marked B30-34A on one side and C722902A on the other side. It's 65mm OD, 30mm bore and 16mm thick. It comes with a single steel dust shield which is consistent with the "Z" nomenclature. It also has the indent for the locating pin.

In fact it is stamped 6206Z on the steel dust shield.

The box has been written over with 91002-259-010 presumably by a parts guy.

So I'm OK with that bearing but it doesn't solve Jensen's dilemma with that really early engine.

[quote="LOUD MOUSE" Here is another one of those engine tops.
No holes at the condenser location............lm]

What part number is that one? Is isn't -060 as it says on the paper slip and it appears to have different baffle arrangement and no oil breather outlet. So we know it isn't a regular CB72 top cover. Any idea what it's off?

Your info supports what I have here and I have more.
Thanks.
I have a HONDA parts book dated 28th November, 1962 which has parts numbers and description (early part numbering system and no HONDA Code reference) for the C/CA/CS72/77 which includes the single/duel seat, low /high pipe, tube and press steel bars and is 145 pages with data for the US and Germany.
Over the production years (1961-1967) HONDA has issued 3 right side bearings.
Ball bearing, pin bearing with One Piece outer race and pin bearing with a steel insert on the outer edge of the pin bearing cage area. (1967)
Your last question may be/can/ possibility be answered if jensen would quit playing games and ALWAYS offer data he has on hand before playing QUESTION GAMES. (engine number)
I for one (some don't read or understand all the info) give all I know when information is asked for.
If the person is able to call me and the reply can/will be lengthy I ask them to call me.
There are several bikes now being run/ridden just this year because I was able to help. (noisy cam sprocket).
I'm waiting for engine number (pic is best) and pics of the engines parts he has for the CB72 engine top.
No pics, no factual answers can be given. ...................lm


teazer wrote:The oldest Parts List i have here is dated June 63 (small 180mm x 128mm format) and it lists only the regular needle roller bearing

Outer race CB721320A
Retainer CB721323A
Rollers CB722924

All are listed as being effective at CB72E-112069/CB77E-110281 with no mention of what came before.

Parts List #2 dated Oct 66 has the same parts but with new numbers as well as the old numbers, and it also lists 91002-259-010 as "Bearing, Ball 6206Z" from CB72E-010001 to CB72E-112068
and from CB77E-010001 to CB77E-110280

There is no mention in either of a -000, but it does raise the question of why it jumped to a revised bearing.

One could speculate that the unusual caged roller bearing may have been used on a different model or perhaps it was used on early pre-production motors.

List 2 does have a complete list of production numbers from 1960 to 1964, but nothing after that and the 1960 numbers start at CB72E-010001.

Could that bearing have been from a C72 or C71 perhaps or maybe from a C/CB92/95?

Hi LM,

Like I said, I don't know more then I wrote down, and rabbits eat carrots.
I don't spread engine numbers on the net, so that's why I asked you,
and I don't like the way this conversation is going.

Ya may not like it any more than I do but ya are the one "Dangling the Carrots" a small piece at a time but never enough info (all ya have/know) from ya to help get info easily.
Just a little more info with each reply!. (sort of like Ya But! to the answers)
As though someone is going to steal your engine numbers for some special purpose.
No pics of the damaged engine????????. ........lm

Thanks again for the heads up.
I checked and I have a One Side Closed bearing also.
Mine is NSK and 830-34A and CH on the outer edge of the outside race and NSK on the bearing cover but no other numbers/letters there.
As this one is a One Side Covered seal and that cover when the bearing is installed (I checked just now) is on the crank side of the shaft.
Ya can bet if/when I use it I'll remove that cover.
My others are NACHI and have 6206S7HS on the edge of the outer race and PH and 30 on the edge of the inner race.
Both have the index lines on the outer edge so ya can install it correctly and not "PUSH THE LOCATER PIN OUT OF THE CASE and damage the case.
Sort of strange why the CA77 parts book refers to this part as a 6306Z part when on the edge ya will find 6206S7HS!!!!!!!!??????????????. .........lm

Hi,

Teazer, I'm sorting out the dilemma on the early engine by cleaning it and look at it carefully (read further). Since there were no suggestions on the forum other then give me more pictures I guess I have to find the info elsewhere, or even worse, not find it at all.

LM, I also asked info about the differences between a 10 mm spark plug head and a 12 mm spark plug head, again, no real answers, I asked questions about the strange engine breather, again, no answers.

I pm'd you with details, so don't say I'm holding back info, I did not find the time to clean the engine and take pictures, I don't like your suggestion, they are provocative.

I don't play games LM, and I don't like you suggest that I do. I make pictures of parts and put them on this forum.

I don't put engine numbers on the Internet of my riding bikes, I just don't like to do that, you certainly don't have to question that, nor make fun out of it.

In the past I asked you for help, and you refused to do so, saying it's not worth your time (cracks in side covers and engine cases). So don't say you always helpful.

I pictured every winker I know off, and there brackets, again, I'm not playing games with carrots and I don't think you're a rabbit either.

Again, I appreciate your help when you give it.

Here under, is the text in the PM to you (02 june), where I give many details about the engine.
I don't understand that you suggest in public that I play games or that I withhold information, I do not.

So Teazer, this is what I wrote to LM, since he was the only one who was reacting on the thread :
Hi LM,

Like I said it's a pre 61 engine, but it hasn't a number.
The only inscription is CB72E 59, so I guess it's a 1959 pre production model.
There is nothing written behind the 59, so also that will stay a mystery too.

It is the same engine with the strange breather, mentioned in the same parts ID section.
I got this engine from someone with two boxes of CB72 stuff, but most parts are different, some more some less. I know that here in the Netherlands is a complete 1959 CB72, but I was not able to trace it down yet. The women I got this stuff from didn't know where here husband (passed away) got the stuff, so I guess it will stay a mystery.

In the box where several alu shock covers, a few 10 mm spark plug heads, and many other very interesting parts. Strange foot peg rubbers with Honda inscriptions in it, an aluminum front fender and a aluminum gas tank cap. the gas tank itself has a slightly different shape, and is holed badly.

The engine has a 360 degree crank, the strange breather, and very rare (and domestic) rotating transmission. Furthermore there are no inscriptions on the rotor, and it has the early dream camshaft sprocket (with counterweights).

It will be very hard to rebuild the engine, because it has a lot of damage, but Ill do my best.
The first gear is teeth less, the shaft is bend severe, the crankcase is cracked in several places. Kick starter shaft is broken in two pieces, and the camshafts are beyond repair.
The crank itself turns free, but the sound is not what it should be, probably the bearings are all shot.

However it is a wet sump engine, so it's not a early dream C71 / C76 special build something, the oil pump is also CB72, so are the holes in the crank where the oil pump fits.

I have this stuff for a month or two and I slowly work through the parts labeling them, but every time I find something different.

I have a lot of early 1961 parts, but I see also many differences between these parts and the early 61 parts.

I hoped that more people would react, so I could learn from the info, but I think that is not the case.

Jensen
I never got any serious info from LM so far, so I guess I'm standing alone here.
