Yes I believe there are. Here are some titles of books that might be
of help to you:
 
 
   Commodore 1541/VIC 1541     Computerfacts from SAMS
                               (photos, schematics of hardware, tips)
 
   Commodore 1541 Disk Drive   from SAMS
   Trouble Shooting & Repair
   Guide
 
   1541 Repair and             from Abacus Software
   Maintenance Guide
 
   The Anatomy of the          (more software oriented with ROM listings,
   1541 Drive Book              description of the DOS, but perhaps hardware
                                specification too.)
 
 
Once again, I don't want to play favoratism by mentioning
any sources where you can obtain this books, but most
companies that carries commodore hardware and software
should have them. Check inside commodore magazines for
mail order companies if your local sources don't carry them. Also check
your local commodore repair centers (in the phone book)
if they have and sell these books.
