  "basis": "Replace rectangular box/front-facing lid and co-axial motor/drive-disc convention with rounded hollow case,outboard cover,perpendicular toothless wheel and separate crank/link/slider roles. The selected outboard X clocking is a reconstruction hypothesis consistent with retained motorZ/rackY drawing axes,not an observed installed orientation.",
  "limits": "No direct owner dimensions,fitted manufacturer suffix,case clocking,gear/sweep variant or nominal46-tooth replacement is selected. All case/cover/port/shaft sections,bore/fixing map,wall gauges,eccentric/phase,link/fork/pin geometry and source contacts are estimates. Existing wheel-centerY/Z,motor can/mount/lead,feed/inter-wheelbox/extension paths,spindle axes,parked arms/blades and surrounding body remain. CaseX orientation and wheel spindle direction change as reference architecture;not fitted axes or a repair template. Smooth input stub ends before the wheel;worm teeth,gear teeth/mesh,internal travel,park switch/contacts,wiring circuit,washer/circlip/bearing stack,thread/flare engagement,lubrication and loaded support are not reconstructed. No operating sweep,park setting,wiped area,clearance,torque,verified service procedure or removal path. Source gaps are construction differences,not measured vehicle clearances. Inspection separation is illustrative.",
