Issues with Eheim 1261 Impeller/Shaft

[xmetalfan99]

The shaft is stuck to the impeller and even after 12 hours of soaking in vinegar it will not budge. What should I try next? CLR?

I really don't want to spend $107 for a new impeller and another $10 for a new shaft.

CLR seems to slowly be removing the calcium buildup. Hopefully I'll get to hook my pump back up by midnight.

A every now and then soak in vinegar will prevent this!

I normally do this every other month, but haven't for a while. Well, I need a new pump now because I dropped the impeller/shaft by accident and broke the end of the impeller off. I superglued it back on as a temp fix for until I get a new pump. What would you suggest? I have been looking at the ocean runners and waterblasters.
