I have a 1973 Triumph Bonneville T140V that is making a crunch like noise when the clutch lever is pulled in. It does it toward the end of the lever movement.
I've replaced the clutch lever, the clutch cable and all the clutch plates. I filed the slots in the clutch basket to remove rough spots and the plates seem to slide evenly.
I've now disassembled the clutch basket again, but I think I can still feel a rough spot when I push in on the end of the actuating rod. Not much, but I'm thinking that maybe the noise is being amplified by the assembled clutch plates, springs, etc.
Looking for ides as what's left that might be causing this noise.
Many thanks.

A 'crunch' doesn't sound at all normal, or like any of the common ailments !
Have you checked for in-out movement of the basket, or up-down play in the shaft.
Chains that are overtight is another remote possibility. ?

Sounds like the balls in the clutch release mechanism are over-ramping.

Good call ...
-
More researching leads me to believe that over ramping might be the problem.
Anyone have any ideas on how to fix this problem?
Thanks.

Yes, simplistically, set the clutch adjustment up by the book. This happens when the clutch pushrod throw is adjusted to push "too far".
-
You could try giving the clutch cable a bit more freeplay, initially ?
And still get the clutch to free off enough.

Yep. Pretty much did that. And the "crunch" went away.
Thanks to all.
