The correct forward gear came in and I had a little time this afternoon so I installed it and buttoned things back up again. Then, I saw the pinion gear right where I placed it so I would remember to put it back in the LU. So, I took it all apart again. Wire wheeled everything back shiny then buttoned things up again. I flipped her over and installed the drive shaft and a new impeller and got the pump assembled and everything looked good. I decided to pressure check the LU and got this!

Where are the air bubbles coming from? Out of the hose fitting?

How much air pressure are you using? and can you give a photo or video of the exact location where the bubbles are coming from?

If your leak is within the black circle I put on your picture, you have a much bigger problem as I do not know ANY reason why, other than a crack that you should EVER see a leak there… I have been wrong before…

Yeah, that doesn’t look good…Looks like the casting is either cracked or porous…Did you see any damage from a previous failure on the inside of the gear housing when you had it apart? I guess I would sand down that area to help pinpoint the actual leak, but you will probably have to pull it all apart again…
I hope I am wrong also…

Probably a crack. I would grind it out slightly, then fill with brazing rod or TIG Weld with Argon, then self etch then paint.
