Thanks AVB... Hate saying, but that its above my technical level. I'm concerned that regardless of whether I modify the shaft or swap it is that I can't back out easily--I'd turn the motor to trash as the parts for these motors seem to be scarce. I'm not following you when you said it looks like someone chopped the new motor shaft? The motor was received new in box. You've got me thinking I should test it! I know better than to assume it works...lol. The shaft doesn't look like what's illustrated in your post--260922 or 397109 as those are keyed protrusion. The shaft on new motor I have is notched.
Something I question is the couplings between the shaft and the pump... I've attached pictures of what mated with the 130902-1015. The pump side looks like it may fit a standard coupling. If this is the case, why couldn't I buy a coupling that mates correctly with the new shaft? I'd also be open to decreasing the length of new shaft if necessary. At this point, I question if purchasing a pump that mates the new shaft is something to consider?
