  "limits": "Right side(-X)filler comparison is supported by donor opposite-slave view,not fitted gearbox identification. All numerical axes/stations,bosses,9mm radius passages,8.5mm smooth shanks and11mm square heads are construction estimates. No catalog thread diameter or taper is promoted to a fitted bore. No threads,taper engagement,oil seal,torque,oil capacity/level,actual access,tool envelope or verified removal path. Case/body/shaft stations stay. Tunnel/floor are not cut to make the estimated filler accessible. UK maintenance artwork supports generic service roles only,not verified1975 North American procedures."
