With any installer, it's critical to grease all the working surfaces with clean EP grease, including the nut threads AND those inside the pump shaft. If the tool breaks, the grease inside will make extracting the broken tip MUCH easier.

I don't recommend using this type of bolt/nut/washer installer because they usually break, but if you do, make sure there's grease between the nut & washer, and in the nut threads.

Never lubricate the pump shaft or the pulley, but baking the pulley might make it easier to install.
