Today I removed my old Leece Neville in preperation to install the new Delco 28SI 160 A alternator. Everything I do seems to always turn into a major project and this was no different. On the Leece, the shaft was keyed and the Delco is not. The instructions say to use the old pulley and spacers of which there were none but don't use the fan. No mention of a keyed shaft. The pulley nut is to be torqued to 70 lb ft. The pulley seems to fit well with no slop on the shaft and bottoms out against the shoulder or boss on the shaft just before the bearing. I don't have exact distances, but the pulley seems to be in the same place and appears to be tight.
Question. Can you install a keyed pulley on a keyless shaft? I'm afraid that if the pulley starts to slip under load, it will damage both the shaft and pulley.
I also ran a wire for the remote sense and don't understand why Country Coach didn't do this as the Leece had a sense terminal.

Go ahead and use the old pulley and forget the key. Not needed. Used a 1/2" impact to tighten the pulley. I did the same change out only with a 200 amp unit.

Ed,
Don't worry about the key. Just make sure the nut is tight. Mine had been working fine that way.
