You can probably save your self a lot of money by replacing just the brush plate and seals, and cleaning the armature. Obviously I haven't had to do this on my 1199, but I "rebuilt" my 749 starter twice. If your handy enough to get the motor out, you might as well open it up, and clean it and try and reuse it. A little digging on Google with the Denso (or who ever makes the starter) manufacturer part number will likely lead you to a pre-assembled brush plate and seal kit. I know on my 749 oil would get into the starter and cook, as well as the brushes wearing. A $15 brush kit was all it needed. A new seal, new brushes and you basically have a new starter. Just note the orientation of the brush plate or your starter motor might spin backwards. It's very easy.
