Hi Happyfeet, The Speedo drive when new is a slip fit over axle.
The axle nuts tend to crush the soft metal of the drive. This can press soft metal into axle threads & make it appear threaded. You can just wind it back on or file/drill hole back to slip fit.
This is huge problem on OIF drives as you must tighten axle tightly. But you pretty much have to drive out to remove as it’s swagged to smooth part of axle.
Your version the hollow axle nuts don’t need to be so tight. The solid axle must be tight though.
Personally I’d probably just wind it back on. You have to line up speedo drive with brake plate, so a little fiddling may be needed to get both lined up & nuts tight.
in every case make sure speedo drive, speedo cable are well lubed. Repro drives tend to be less durable than originals, so we need to protect drive. They like to be well lubed.
Clever machinists make & insert a steel bushing into drive center which is what factory should have done.
