Topic: “D” Washer Application Question, 1976 CB750K?

Does a 1976 CB750K use these washers?  Fiche shows the D washer on the 1969 - 1975 CB750K, but not 1976.  Ready to order them but now questioning if my bike should have them. Thanks, Jim

I was discussing split washers on the Facebook 750Four site and referenced this topic for making the washers.  One contributor there Andrew Koppenhaver offered the following information about which 750s used these washers:
it's easier to remember which ones don't need them.  K7/K8, and F2/F3 are the only ones that don't require the D washers. All others (the early unicorn type, dashboard type, early F type) require the D washers. That change happened sometime in 76, when they started producing the late model bikes.

but please note also that from my research on CMSL.COM, it appears the same part number 53235300000 (so same size) washers were used on 500, 550 & 750 up to 75 and in some cases part way through 76.  You have to search to find the frame or VIN number to identify the cut-off.  For the 750F, I saw that information on a post here on SOHC4.

I think I found this in tips and tricks think to MCRider

Good information.  Thanks!

On the 500 it's bikes with 7mm bolts that don't need D washers. May be the same on the 750s.
