How to press the PMA back on the Crank shaft , with motor in the bike ??
I've seen a few aftermarket tapers that were quite crude and not suitable to create the "stick" a taper needs to work properly. If they can't machine a decent surface what are the odds they got the critical taper angle spot on?
Absolutely right!!! A woodruff key is much more than an indexing tool.....then this information from inexperienced self called engineers with big followings is not only dangerous it is also reckless
I have very little experience with lathes beyond metalwork at school where I vividly remember starting up a lathe with the chuck key still in the chuck.Peanut, there IS a scenario where a tapered shaft woodruff key isn't used, and that's on lathe tooling, like the Morse tapers. I'd rather the taper slip before destroying a lathe spindle or tailstock.
However, it'd be a pretty serious condition that would lead to where having a slipping rotor could save a crankshaft on a bike...
So many ignitions do no use keys. the old ALD, PVL , ELECTEXWORLD. I have used all of them for racing ( no rapid acceleration there) and never had one come loose. I have even had the 1/2 starter nut we use to remote start come loose but the rotor does not. SO I would not call it a safety feature.
I have run an xs650 bought new in 75 and ran until 84, and it ran with points. Always ran great, but I would never go back there after running the Powerdynamo. set and forget.
And I ask all you guys who never used one to try one. With all due respect. Don't talk about something you never used.
All of the ones I mentioned. They come not keyed.so do you fit your xs650 alternator without using a key ?
