| + | **Using a hydraulic press**: \\ | ||
| + | This method was submitted by XLForum member, Fizzle, as an upgrade to his 1977 oil pump. \\ | ||
| + | His goal was to glue the seal squarely in place using a retaining compound so it could not come loose, stick out of the plate and jam up the pump. \\ | ||
| + | |||
| + | I removed the protective blue paint from the seal with 91% iso alcohol, then scuffed the OD of the seal and the ID of the plate with 600 grit wet/dry sandpaper. I then thoroughly cleaned the two parts with 91% iso alcohol and applied a liberal amount of anaerobic retaining compound to each. I chose to use Eskonke brand from Amazon because it's way cheaper than Loctite, I could get it next day, and Eskonke provides a very useful application chart for their products. \\ | ||

| + | I have a bench-top hydraulic press, so I positioned the seal in the hole and set the parts on a steel plate, covered them with a second plate (not shown), and pressed the seal in flush with the top of the outer plate. I found that the OD of a 5/16" flange nut fits nicely on the seal and within the hole of the outer plate. I used that to press the seal a bit deeper into the hole so it would be recessed on both sides of the plate. I could only guess on how much more to press it and got lucky, ending up with 030" on one side and .040" on the other. If I do this again for another pump, I could place something at the bottom of the hole to limit how deep I press the seal. \\ | ||
