ZA50 drive gear. Is this Normal?

Rebuilding another ZA and don’t remember there being a space between the drive shaft and drive gear. Are these two piece?

Does this need to be pressed together?

This is what mine looks like

Ugh. Looks like I have an issue. I like your extra groove for a snap ring to hold the sprocket.

Thanks for the pic.

So has anyone seen this gear/drive shaft apart? I assume it can be pressed back?

Re: ZA50 drive gear. Is this Normal?

never seen that but i'd definitely just press it back, got access to a press?

Re: ZA50 drive gear. Is this Normal?

Yup plan to. Thought Roff would wade in given his ZA experience.

They made two styles or versions. Just on the sprocket side.

Re: ZA50 drive gear. Is this Normal?

Yes I now get the differences on the end shaft at the sprocket. Wondering again about the gap that has opened up on the shaft where it connects to the gear. I thought this was all one piece.

Will try heat and a press this weekend to try and close the gap.

Thanks for the responses.

Maybe try a deep well socket and a hammer ? About 2 seconds worth of worry . ;)

Re: ZA50 drive gear. Is this Normal?

Heat and a 12T press and it closed the gap.

Re: ZA50 drive gear. Is this Normal?

The one I bought had the same problem and it's caused from running your drive chain too tight.
