+===== Oil Pump Check Ball Seat Lapping Tool ======
+**Homemade check ball lapping tool**: \\
+The tool on the left is a homemade check ball lapping tool used to lap the seat where the check ball sits in the oil pump (57-76). ((Toolmaker of the XLFORUM https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/72481-i-m-sick-and-tired-of-wet-sumping?t=499487&highlight=check+ball+lapping+tool)) \\
+It's made with a tool steel shank and a 3/8" carbide ball tip on the end. \\
+The pocket for the ball to sit was cut with a 3/8" ball end mill then a few drops of Loctite 404 to keep it there. \\
+**Check ball seat burnishing tool**: \\
+The tool in the middle is a check-ball seat burnishing set. ((DaWind of the XLFORUM https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/109149-oil-pump-check-ball-seating/page2?t=1013445&page=2)) \\
+The idea is to turn the ball into the seat several times, thereby smoothing it to a very fine finish. \\
+It works quite well with these old check valve seats, but you can and do use quite a bit of force with the cast iron for a good result. \\
+The aluminum bodies on the Sportster pump would require a somewhat gentler application of the wrench. \\
+But the result would be a micron finish on the seat that will hold those slippery oil molecules. \\
+Problems with this procedure include factory machining of bore and seat rather badly out of alignment on a few pumps. \\
+And pitted or damaged seats that no amount of force will correct. \\
+You'd probably need a lathe, a tap set and the ability to braze or silver solder to make your own tool. \\
+Although you might drill out and tap an un-needed pump nipple for part of the tool. \\
+You can indicate the bolts in the chuck, face off the ends and then center drill them to provide a concentric pocket for the sphere to rest in. \\
+Then, hold the whole mess in tension between centers as you soldered. They surely have to be straight or they aren’t much use. \\
+**Check ball tester and oil pump prelube tool**: \\
+The tool on the right was made as a check ball tester and oil pump prelube tool. \\
+With this tool, all you have to do is use a grease gun (without grease) filled with oil and pump it into the system so a dry start can be avoided.

-|There are 4 bolts on the 77 and Up gerotor oil pump. But only 2 are used to bolt the pump to the engine \\ (front outside and rear inside). The Allen head cap bolts have 1/4"x20 threads and a 3/16" socket head. The \\ front bolt can be removed / installed with a regular size Allen wrench but the rear bolt is inside the frame. So \\ you have to go between the frame and the engine to get to that bolt. A regular size Allen wrench is very \\ difficult to use as the 90° bend on the end hits the frame /engine. \\ This 3/16"x6" Allen socket makes the job a lot easier.||

+Mounting bolts (to the engine): \\
+-97 models - (4 bolts) \\
+-Up - (2 bolts - front outside and rear inside) \\
+The Allen head cap bolts have 1/4"x20 threads and a 3/16" socket head. \\
+On 98-Up pumps, the front bolt can be removed / installed with a regular size Allen wrench but the rear bolt is inside the frame. \\
+So you have to go between the frame and the engine to get to that bolt. \\
+A regular size Allen wrench is very difficult to use as the 90° bend on the end hits the frame /engine. \\
+This 3/16"x6" Allen socket makes the job a lot easier. \\
+The Allen wrench doesn't have to be 6" long. This one simply gives you more room to work. \\
