Okay, decided to replace the old variator on my 1965 AV88. It's still in decent shape but don't trust it because of the age.
So after an hour battle trying to get the last cir-clip off the engine shaft without the correct tool, I succeed. The variator came off and out popped the key. I noted the keyway on the engine shaft.
The new variator is identical to the old one in every respect EXCEPT there is NO KEY SLOT in the variator hub! WTF?
My questions are:
1. Is friction/an interference fit enough to keep the variator hub from slipping on the engine shaft with no key? It would appear so as they keyway is eliminated in the new hub.....what do you all think?
2. How do I install/solidly seat the new variator hub on the engine shaft?
Any advice greatly appreciated.
