Yup, when I built my first Harley around 1986 I bought some SNAP ON brand tools for the compensator nut/tranny input shaft seal/primary drive system... BIG stuff, 3/4" drive (sockets, removable handle breaker bar, removable handle wrenches) and it seemed like a TON of money at the time but 25+ years later I have used those tools MANY times for my second harley build and many other tractor projects and such...
AND I can/could say that I built them all by myself... :)
A balljoint service kit is absolutely a handy kit to have in your toolbox...
