Hey All
1985 XT 600 kick start
I've put about 700 miles on bike without a problem. All 3 bearing sets in rear have 700 miles on them.
This last weekend I tighten chain 1 notch both sides (possible slightly further 1 side). Rear was tightened back up. Seemed fine. Drove a few minutes felt fine. Took on highway and felt vibration in foot pegs when I got up to speed. Got off next exit, slowed almost to stop and could smell the rear hub. Then back hub locks up and won't move. Pressed brake then released, back it up a bit then I was able to roll to side. After it cooled i loosed chain and slowly made way back home.
Attaching these pictures
#1, 2, 3 shows bearing on sprocket side half out and where the sprocket case seemed to be grinding into wheel hub.
#4 shows the lip on hub brake side ripped away
#5 shows melted casing on drum panel
#6 shows metal deposits from cast casting

The bearing on drum side is shot (very knotchy) other 2 bearings seem fine.
I did not torque rear axle but it was tight.
chain could of been very slightly off line, but no more then 1 notch difference.

Any advice on what you think happened would be great. Besides the lip being grounded off the wheel seems to be okay when I but another drum insert in it.
The other 2 bearings seem to not of suffered any damage but should i replace?
Thanks
Greg
