Split clutch today after ordering new parts inc heavy duty springs, so I could rebuild,only to find the clutch was not the issue.
It was the last person who worked on the clutch 25 years ago,obviously they didn't have a torque wrench as the bearing carrier had drifted loose.
No wonder it sounded like a can of marbles.
The retaining nut was loose and not locked with the lock tab
Well while i was in I replaced the bearing and seals,checked friction pads,which were fine
Torqued retaining bolt to 34lb and locked with tab
Replaced damaged bolts & torqued to 9lb
Rebuilt and all is as should be
Glad the bolts drifted out while pottering about at home and not on a run to coast
