5a Scraps a few words in speech (7) A???A??
15a Part of mechanism leaking fluid (7) ??N???E
6d Memory possibly defective, Charlie admitted (7) ??C???Y
8d Very much America’s March man? (5) ??U??

Thanks in anticipation

5 Affrays, scraps (fights), sounds like A Phrase, a few words.

15 Linkage, part of mechanism, anagram of 'leaking'.

8 Sousa, composer/march man (he did some famous marches). So, very much+USA, America.

6 Faculty, memory. Faulty = possibly defective, with C for Charlie inside (admitted).
