Abstract: A scribe saw assembly is provided for a loin puller and has substantially reduced wear and increased life of the assembly components. A pinion assembly includes a double keyway and opposing cutouts on the pinion shaft, with dual needle bearings. A bevel gear assembly includes pins for holding the scribe saw blade and dual bearings on the bevel gear shaft to eliminate shaft flex and blade wear. The standard is mounted to the motor housing with load bearing pins to prevent loosening of the mounting bolts. An adjustable ski is provided on the standard to control the cutting depth of the scribe saw blade.
