Warning: Anal Alert!

Have you ever got your parts back from the plater and picked up a washer and wondered where it was used?  There are approximately 350 washers (flat, lock, special) on a CB750.  About 125 of those are the 6mm (94101-06000) & 8mm (94101-08000) thin (Form B) flat washers.  Even these washers are somewhat special.  The standard 6mm & 8mm washer that you can buy in the US are twice as thick.  Anyway, the remaining 225 or so is made up of over 40 different sizes and shapes, some there are only one of.

A few years back, on my first restoration, I didnít pay much attention when I took apart the bike and threw all the parts in a can for plating.  When I got them back it was the washers that drove me the craziest.  I actually bought one of many of the different sizes just so I could identify what was what.  It was then that I started putting all the size info on a spreadsheet so I could easily identify each part.  I have since paid closer attention to where the parts came from and did a sheet for screws, nuts and pins & spacers.  By the way, there are approximately 450 screws, 120 nuts and 100 pins & spacers.

Not all of these pieces are plated.  And some of them I donít bother plating when I can buy them, especially in bulk like the 6mm & 8mm washers.  But some of the washers, larger nuts, spacers, etc., are hard or impossible to find or they are expensive to buy individually and replating makes sense.  In any case, these spreadsheets have been helpful for me and I decided to post them because they might be helpful for someone else.

Now a disclaimer: I tried to make them as accurate as possible but I still occasionally find a mistake, so use them at your own risk.  They will be the most helpful for restorations, especially sandcasts as most of the info came from two early sandcasts, one that had been worked on with missing parts and the other pretty complete and original.  I know that some of the parts are different on other sandcasts and especially later models, for instance some of the screw lengths are different on the K0 valve cover.  I always make sure there is adequate length and that the screws arenít bottoming out in the holes when reassembling.  

That said there is still plenty of good info there for early K models too.  For example, if you want to compile a list of all the cross-type cap screws to change them to socket heads, this would be a good place to start.  Or if you have a bit you canít identify you should be able to find it.  I also use them to keep track of what I have so I can figure out what I need to buy.

I tried to list substitutes where possible, superseded parts, where theyíre used and other notes so they got kinda large.  Thatís not a problem for me because I have a printer that can print on 11Ē x 17Ē paper but once you copy them you can change them to suit your needs.

I will try to keep them up to date and add info when I can.  If you see a mistake or have some info to add please let me know and I will make updates.  Hopefully they will be helpful for some one.

I added my bearing spreadsheet.  It has cross references to different manufacturers and includes the needle bearings for the primary sprocket.  I got a lot of it from sources on the forum and just compiled it in one place.  If you see any errors please let me know.  Use at your own risk.  I hope it helps.

Thanks.

I was going through the bearings to make a list for my project and I found a couple of mistakes.  I got the mainshaft bearings mixed up and changed the number on the left bearing on the final drive shaft.  I hope I didnít cause any confusion.  I also added the Yamiya part numbers and their prices just for reference.

For what it's worth, Yamiya's prices were lower than my local bearing supplier.

Mark, bump and minor update info. The first CB750F parts manual, 1975 I think, shows the Honda Part Number for the needle bearings in the primary drive: 91010-300-008.

These bearings appear to still be available from Honda Car Parts Dealers, as 91010-300-008 & 91010-568-310, since they are used in some Honda auto models. Interesting IMHO.
