[AT] JD 620 clutch cover keeps working loose

[Brian VanDragt]

The flat spots on the cover are clearance for the adjusting nuts. The flat springs should snap over the curled edge.Brian

Any pro tips on how to keep the clutch cover in place on a 620? It's just a press-fit situation.   The cover has a lip around the edge, mostly curled over but with three "flat spots" 120 degrees apart.   They align with three spring clips attached to the inside of the pulley.   Everything looks good and uniformly shaped and not beat up or broken or weak.   But two or three times over the past couple years I've had to carefully reinstall it, tapping gradually with a rubber mallet to get it to seat fully all the way around.  Looks fine for a while but then it always slowly works loose again. I had the tractor out this evening for some rear-blade work on a little lane I'm trying to fix up, and it worked and sounded and looked great as usual... but you can see that missing clutch cover.
