Topic: Diamond chain part number & source.

Also does anyone know how many chain links will going 18tooth to a 17tooth front sprocket give me??
 ???ONE

[Markcb750]

You cannot remove/add just one unless you use a half link, and I think the fact that half links make the chain wider where they connect might cause problems in the transmission case and chain guard areas.

102 will work fine, I think. Mine worked with 100 link with a 17/48 combination on a 1976.


HondaMan offers sound advice on number of links.

Thanks Markcb750, I was just worried that since the 78cb750K swingarm is longer that I might have needed another couple links.

I hope so too Im in the same boat, just waiting for it to come in. kinda slow on shipping.

Got my "Diamond" chain today from KSCDirect.com!  wahoo! 

I gotta go see those guys, maybe next Friday when I'm off.

Got my chain today as well.
Unfortunately I was not as lucky ordering from Babbitts
I ordered a 17 tooth front sprocket and a 48 tooth Honda rear sprocket for my 76 cb750K,
have waited 10 days and yesterday one sprocket showed up (the 17 tooth front sprocket)
I was charged for both of them and was never contacted to let me know that the 48 tooth rear had been discontinued. So I paid 16$ shipping for a 31$ part. I called them and got a refund for the 48 tooth sprocket.
 Anyone know where I can get the Honda 48 tooth rear sprocket for my 76 cb750k?
Thanks

If you absolutely cant find one stateside, I may be able to help. (not the fast solution)

 You could try used, often they are pretty good, take a chunk of chain to check if needed.

If it is a discontinued part, it may be time to stir up my machine shop friends who are full of lightly-used CNC equipment these days. I'll have to ask them what it might cost to run 1000 sprockets at the Honda spec, which no one else ever seemed to catch onto.

I've recently received several requests from y'all about "where can I find the Diamond chain you talk about?".

So, I bought some, and know they can be had, from Kaman Industrial Supply. If you can't get an account yourself at your local Kaman dealer, let's get a list together and I'll see if I can make a quantity buy from my alma mater's shop: they let me do things like that, still.

The Diamond part number is: XMC-1548-M-102P for a 102-link chain.

Be forewarned: I paid almost $100 each for these chains, and I consider them the best you can run on the 750, in particular. (No, I don't wish this to become a "chain thread", please...) It is made to cope with the vagaries of the alignments that come on this frame system, and run very quietly on the oversized base circle of Honda's sprockets, a perfect marriage. I have personally run these chains as much as 38,000 miles, then retained them as my backup chains, because they only stretched 1.5% at that distance. I normally replace my chain at 1% stretch, 'cuz I'm picky...

You can install this chain directly, or cut off one link to make it the OEM style 100 links as found on the K0-K4 with 17/48 or 18/48 sprockets. I usually install the 102 length, so that the chain adjuster marks start at the first "notch" in the back (otherwise, it ends up ahead of the notches).

Mark,
At Kaman tools (kamandirect.com) they list several types of 530 chain available from Diamond. The part number you mention above is there (XMC-1548-M-102P) and also XDL-1557-102P. In your CB750 book you mention the XDL chain as the best choice. (There are also "XLO" and "XNI" versions listed.)
Which one do you recommend, XMC or XDL

Thanks for clarifying this !!!

Cheers,
Tommy

Definitely go with the XDL series: they are the ones with the hard-as-nails rollers and pins, and the extra clearances that wick out the dirt for us.

Hey livetoskate

I'm using a 76 750F1 frame with a 76 750K6 swinging arm, I don't have an old chain handy but have used this calculator at:
 
http://www.rbracing-rsr.com/chainlength.html

to calculate 104 links for a 530 chain. Using 17T or 18T front with 48T back sprocket.
Let me know if the 102 is long enough

[ksmith0034]

I just ordered DIA XMC-1548-M-102P
530 RIV 102P
from kscdirect.com for $53.70 incl shipping.  Now I just need to order the 17/48 530 sprockets!
Have I ever mentioned how much I love this forum?!

[dhall57]

yeah ksmith, I order the same chain for my 750 K6 several weeks ago and also got 18/48 sprockets from Z1 enterprizes

[cookindaddy]

Is there some advice on this for the 630 o-ring chain used on the 78 CB750? I'm looking around for a replacement chain. I have standard sprockets (stock). Thanks
