Hi TC,
Unfortunately at times the PTO shaft gets some type of burring up by either the cotter not being done up tight enough and thus with a bit of looseness it will create wear and burr up the sides where the cotter pin touches the shaft, also with the later clutch assemblies that utilise the two pointed grub screws that dig into the shaft and create high spots around the points will also make it hard to simply slide the clutch half off when required.
Member Bon_Scott's $80 job was merely for sharpening only and not set up, but I'm pretty sure that's what you were implying.
Nonetheless that's a super price for that part of the job.
Cheers,
BB.
