Have some pictures of the body head and gears of this pump. You'll see what I mean from the gear side pressure and it's about .010 deep. The one with the deepest undercut is the driven one. Picture of the gear was hard to focus on but you can see the curl on the trailing edge of the gear. Don't know if that is wear or pressure build up between the gears. If they're not made right and the mesh is too tight, they build pressure just coming together, IE trapped oil. These are good pumps and I think with a few changes they could be made better.
