One idea to repair excessive gear endplay would be to punch a 1/2” hole in some 1-1/2” disc shims, 0.002 thk then install one above each gear. The only difficult thing to DIY is getting the ID punched exactly in the center… or just use a 5/8 ID punch LOL.https://www.mcmaster.com/product/2904T62[/quote]

Whoa!! That procedure would just be trading a headache for a stomachache. The low oil pressure doesn't care on which end of the gear the excess clearance exists, only that it does. The only cure for excess end play is removing material from the bottom of the pump body.
