KZ400 Rear sprocket hub
21 Nov 2024 15:39
Question. '77 KZ400 Deluxe.
I came across this while replacing bearings, seals, O-ring etc. Is there supposed to be a groove where the black ring is? This is where the o-ring sits from the hub. It doesn't seem too deep. Since it doesn't spin I can't imagine how it would wear a groove? Thanks in advance!

All the parts lists I can find do not show an o-ring located on the interior of coupling a grease seal on the exterior of it and a bearing Here is one from a paper parts list

Did not mean to indicate an o-ring was not on your machine. Rather that I can not find an parts list that shows one. Could be my lack of searching skills.

Yes, I know. I even posted a picture of it where it sits/rides on. In the original post. My question is there supposed to be a groove where it sits/rides. Not where it’s installed on the main hub but where it rides in the damper section.

Ah, okay. So a worn out wheel/sprocket hub bearing or some weak rubber damper elements on hard (de-)acceleration can create a relative woobling movement. All this could made this wear imprint on the sprocket hub....

Ok, so I’m to understand that there is not supposed to be a groove? Supposed to be smooth and flat?
