The lip on the seal is pushed tight against the bore it rides in, creating a positive seal. Make sure you have extensions for each drive. It also eliminates the possibility of stripping out any threaded holes in the case when using air impacts or air ratchets. It leaves no oily residue behind, and also works quite well for cleaning internal components.
Place the gasket on the case first, and then thread the studs into the case by hand. You can drill a hole in your workbench to accommodate the protruding shafts of these drums if you need to, which allows the tool to be used on a flat work surface if a large vise is not available. You also use compressed air for drying parts, and for air-pressure-testing clutch packs, servos, etc. Even better news is that, with a little extra effort, you can improvise or fabricate a tool for most any particular operation.
