The issue with disassembling the motor is that you will likely tear the the very narrow and thin gasket. They crumble very easily and making a new one would be a monumental feat. Maintaining the gap between the two halves is crucial for the paddles to make the correct amount of contact. The original gasket provides this. Sealant may or may not maintain this spacing, and then there is the issue of sealant oozing inside, gumming up the works.
I sure would like to hear about a technique which a do-it-yourselfer could use to reliably perform that task, as I have a box full of wiper motors which need rebuilding.
