Part of the Yanmar Parts Manuals.
This 223-page Yanmar VIO50 parts catalog PDF covers the 1993-1997 VIO50-CR and VIO50-PR crawler excavators (OEM Y00K2912, engine 4TNE88L-RBV). Use the exploded assembly diagrams to identify exact replacement part numbers across 15 assembly groups — from hydraulic cylinders, swing and drive motors, and control valves to undercarriage, cab components, and working equipment. Each diagram maps every component to its Yanmar part number with model-variant columns showing which parts apply to VIO50-CR, VIO50-PR, or both. No repair procedures or torque specifications are included — this is a parts-identification reference for ordering correct OEM replacements.
