New (to me!) '77 CB400F - US model
Nurse Julie:
These is, or should be, a little anti rattle tube on the lever fitting as well. When these are shot or missing it makes the lever feel even looser.
Edit...him indoors has told me I'm loosing the plot, the anti rattle is on the brake lever...doh :-\

I hesitated to refer to the looseness I described as "free play", because the movement I encountered wasn't just in the expected direction of travel. The cable mount end could be gripped and pulled and pushed in and out a bit - laterally, 90º to the normal "rotational" direction of travel. I could also hold the other end with two fingers, directly over the mounting nut, and pivot (not rotate) it slightly - basically the same movement just described, but in any direction. Almost as if the adjustment spindle it was fastened to was made of a stiff rubber material, rather than solid metal? Yet the locking nut was very tightly fastened... it's difficult for me to describe. A short video would reveal all, but I'm away from the bike this week.
Would that rubber oil seal behind lever arm allow for such movement?

My parts book calls it simply a "bush" - mine was in place, but in many tiny pieces. What a pricey little headache! I bought a replacement for $3.00 (about as cheap as I could find it), as part of an order for a few more items. If I knew the proper size and composition, I probably could nip down to my local hardware store and find something that would work fine for $3 a meter instead of $3 a centimeter, but that's the way it goes...

Answered my own question...
before, pretty greenish finish:
[ Guests cannot view attachments ]
after soaking the lower half in vinegar:
[ Guests cannot view attachments ]
pretty greenish finish is gone (note the "vinegar-line") and there's a similar greenish rainbow sheen on the surface of the vinegar I'm soaking in. Hopefully I can just clean it and lube it and it will stay happy...

Got the new clutch cable - it's identical in every dimension to the frozen one that came off, so that's a win! Full marks to the seller who didn't know what he had, but went out of his way to post photos and take measurements to help me decide...
Does this thread belong on the "projects" board? Does it make sense to keep adding to it here?
