I wonder if any of the SSDT riders have come across Ben Doon or Phil McCavity?

Ben doon, is sidecar with Ivor Biggun

Beyond the silliness, the OSSA now runs well.

After the flywheel and crank issue, I suggested run it a bit then lets ensure the flywheel remained tight, but also since the case screws were loose, we should check the clutch nut and cush drive.

Yesterday, checked flywheel, verified no issues, but did remove nut and retorque with fresh loctite.

Countershaft sprocket was loose, tightened it and folded the tab washer.  

Also rechecked center case screws were tight.  All good.

Removed clutch cover, no cotter pins on the clutch spring nuts.  No issues and not surprised.

Removed clutch springs and plates.  Clutch inner basket, proper torque 65 / 70 lbft.  Not even close.  Finger tight plus a little.  Maybe 5 lbft to remove the nut.

Cush drive, same required torque of 65 / 70, it to was 5 lbft max.

Both are supposed to have lock washers and loctite.  Lockwasher yes, loctite no.

Cleaned all threads and reassmbled to proper torque with loctite.

Assembled and ran the bike.  Initially clutch worked, then began dragging until the clutch went inop.

Dis assembled.  Found the cutch inner basket had a depression from the needle bearing inner race.  This caused insufficient clearance between the inner and outer baskets when hot.  Machined away the worn area.  Reassembled again the cush drive and clutch to proper torques with fresh loctite.  Again reassembled the clutch and saftied the springs.  

All back together, fires right up.  This time the clutch releases predictably even when hot.  So maybe, just maybe, since there are no fasteners between the center cases, this thing can run until it needs bearings or a top end and then we can replace the crank.

Also, cush drive removal.  We had purchased the cush drive puller from Alex Snoop.  Without question, money well spent.
