What should my multimeter read when measuring and what is the idea of the way to write its capacitance? Currently my multimeter reads something like 0.177 uF when connected to the two legs.

Your multimeter reading looks about right. Electrolytics have a very wide tolerance on the capacitance value. The motor fault may be something else.
