Just a heads up. One of the TCL bolts behind the primary came loose. It got into the disk brake and then flung into the primary. Cracked one of the tabs holding the primary weights. Also wore on the back of the primary before it completely came out. I’ve never had the primary off. Both the disk and primary are being replaced. Not sure why it came loose. But if you pull the primary off might not hurt to check those four bolts to ensure these are tight.
