There is a roll pin throughh the impeller. But that didn't matter. When I unbolted the gearbox it slidright off the splines.

The splines on the shaft seem 'ok' (needs closer inspection).

But the mating splines on the ID of the impeller are shot. Completely. (Pics coming... As soon as my son finishes his video games)

So I need either find a new impeller, or get creative on fixing the splines on the ID (too big for my lathe to swing and this would need to be in balance reasonably well, so just any old hack job won't do)

Also the back side of the impeller was starting to rub the housing (some thrust load wear, or adjustment needed)

It was time this thing got an overhaul.

Q3). How hard is it to find a replacement impeller (and how $$$$)

Q4). Instead of replacing, any ways to repairing a spline ID?
