Part of the Yanmar Parts Manuals.
All 131 pages of this Yanmar Vio50-2 Parts Catalog (OEM #000Y00S4160) are organized around one job: putting the right part number in your hands, fast. Covering the Vio50-2, Vio50-2 (EP), and the 4TNE88-EBVC engine, this is the factory-issued reference for your Crawler Backhoe Excavator. Inside, you get two pictorial indexes cross-referencing every assembly, from the hydraulic oil pump and control valve stack to boom cylinders, travel motor, swivel joint, and crawler components, each figure keyed to an exploded parts list with OEM part numbers. Spec callouts are built into the electrical pages: the main circuit takes a 50A slow-blow fuse; work lamp bulbs are 13.5V at 2W. Hunting for a part number shouldn't eat your afternoon. Bookmarked by assembly and searchable by keyword, jump straight to Hyd. Oil Piping, Arm & Bucket Link, or any exploded view without paging through the whole catalog.

Yanmar Vio50-2, Vio50-2 (EP), 4TNE88-EBVC Common Problems This Manual Covers
Yanmar Vio50-2 fuel system part numbers needed, replacing tank pickup screen and inline filter
Open the engine parts diagram and locate the fuel system assembly breakdown. Fuel tank pickup screen, inline filter, and all associated hose connections are itemized in the parts list alongside the diagram. Check page 16 for the correct fuel line grommet part number: the catalog lists grommet size 16x20x4.5 mm at that location.
Manual Section: Parts CatalogHydraulic filter part numbers needed, system slow and weak after suspected fluid contamination
Pull up the hydraulic parts diagram and find the filter assembly section. Main hydraulic filter and return filter are listed separately in the accompanying parts table. When ordering replacement seals, the catalog specifies o-ring size 1A P-34.0 on page 41; cross-reference that size against the filter housing seal position in the diagram.
Manual Section: Parts CatalogStarter motor won't engage or cranks too slowly, need correct replacement part number
Locate the engine parts diagram for the starter motor assembly and its sub-components. Cross-reference the wiring diagram parts number list on page 12 to identify the starter relay and solenoid part numbers. The main power circuit runs through a 50A slow-blow fuse (page 29); verify that part number if you suspect the fuse also failed.
Manual Section: Parts CatalogWork lamp burned out, need correct bulb spec and housing assembly part number
Open the cab and interior parts diagram to find the work lamp housing assembly and mounting bracket part numbers. The catalog lists the replacement bulb at 12V, 55W on page 33; order the bulb by that specification and confirm the housing part number from the exploded view.
Manual Section: Parts CatalogHydraulic hose o-ring sizes for boom cylinder fittings, need correct seal part numbers
Check the boom and attachment parts diagram and identify each hose connection fitting position. The catalog lists o-ring sizes up to 1A P-75.0 and 1A G70.0 on page 86 for larger cylinder fittings. Match each fitting's position in the diagram to the corresponding o-ring part number in the adjacent parts list before ordering.
