| + | ===== Oil Pump Check Ball Seat 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). \\ | ||
| + | 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. \\ | ||
| + | |||
| + | **The tool on the right** is a check-ball seat burnishing set. \\ | ||
| + | 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. \\ | ||

| - | |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.|| | + | ====== Oil Pump Removal ====== |

| + | Mounting bolts (to the engine): \\ | ||
| + | 77-97 models - (4 bolts) \\ | ||
| + | 98-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. \\ | ||
