| Success!Something I completely forgot to mention. When you hold the autorotation clutch parts in your hands, outside of the mechanics, (old clutch, not new one), did you happen to detect any drag of the inner shaft when rotating it in the unlocking direction?
You stated that the insides of the clutch looked OK but I can't tell if you knew the details to look for, so under the circumstances it would look OK.
Remember how I was telling you about the springs pushing on the sides of the clutch rollers? That spring force is absolutely critical to the consistent locking function of the clutch. Some experience is needed to tell how healthy those springs are but by having a new clutch in-hand, making the comparison is easy.
The new clutch will produce an obvious drag on the inner shaft when turning it in the unlocking direction. An older clutch may have noticeably less drag and this is due to the springs being distorted or over-squashed, removing the needed tension used to force the rollers into the wedging ramps. Probably too late now to have you perform the test but remember this for the future.
