as shown in fig4 it prevents wear sleeve 24 from rotating relative to rotor shaft 52 b it captures axial loads from rotor assembly 52 some of the features and components of the seal cartridge assembly 26 are shown in fig1 and 13 body 27 has a wet side 31 in contact with the working fluid such as a liquid engine coolant and a dry side 29 the body 27 also contains a plurality of holes 47 for attaching the seal cartridge assembly 26 to the encapsulated stator assembly 57 using bolts 48 a seal 53 is press fit into the body 27 and plugs an opening on the wet side 31 referring to fig1 the wear sleeve 24 is machined to form an inner diameter and has an axis coaxial to an axis of the body 27 a hole 25 is machined transverse to the wear sleeve axis and is configured to receive drive pin 30 the rotor shaft 52 b has a transverse hole 56 that also receives drive pin 30 returning to fig1 the front bearing 51 being press fit onto the substantially cylindrical wear sleeve 24 plugs an opening on the dry side 29 the bearing 51 and wear sleeve 24 are press fit into the cartridge body and the wear.
