CONCEPT ONLY; NOT ASSEMBLY FIT VALIDATION. Both flanges: disc OD57 thickness4, 6x PCD48 5.5 clearance; hub OD30 protrudes 20 from the base. Mirrored. Shaft nominal 12 x 125; z=-181.5..-56.5; motor hub z=-70..-50; motor insertion 13.5mm assumed and axial gap to base 6.5mm. Wheel hub z=-188..-168, front plate z=-192..-188; hub engagement 13.5 mm; plate bore overlap 0.0 mm (this is not extra key engagement). Rear bearing retained; front bearing shifted 12mm to wheel; switch 60mm with 1mm nominal gap on each side, cam shifted 6mm; rear/front hub clearance to simplified outer bearing 0.5mm nominal. KFL approximate 48 bolt pitch and 14.5 inner width, housing/protrusion guessed; 8mm plate 30.2 hole guessed; 60mm switch/wire envelope placeholder, its 47mm hole is an assumption. Wheel70 is real STEP, mirror/phase0, rear face in contact with front flange disc, PCD48 hole centers align nominally; bolt direction, washer and tool clearances not checked. Real converter/70 STEP hole OD4.234, fastener M4 feasible only with washers and actual size checks; M5 cannot pass nominally; hole intersections/phase and actual hardware must be checked. Shaft endpoint keys not modeled; front hub insertion alone does not establish permissible torque. Actual axial gap, M3 nut, alignments, float bearing arrangement, switch/fan/angles, bolt heads, tool accessibility, and fit/strength not verified.
