All 137 pages of this Yanmar B22 Series Parts Catalog (OEM #000Y00S3351) focus on one thing: putting the right part number in your hand for the B22-2C AY-1, B22-2CR AY-1, B22-2P AY-1, and B22-2PR AY-1 mini excavators. Open it to a full Picturesque Index that maps every major component by location and figure reference, then drill straight into exploded views covering the engine and related parts, undercarriage and frame, hydraulic oil pump, control valves, all six piping runs, boom and arm assembly, and the complete electrical system. Every assembly breaks down to individual part numbers with cross-references across all four variants, so you know exactly which items are shared and which are model-specific. Need the work lamp spec? It's a 12V-60W bulb. Fuses run 5A, 10A, and 15A cartridges, and paint codes are documented down to Munsell notation. No more chasing part numbers through dealer portals. Bookmarked and searchable; pull up any assembly on your tablet and order with confidence.

Yanmar B22-2C AY - 1, B22-2CR AY - 1, B22-2P AY - 1, B22-2PR AY - 1 Common Problems This Manual Covers
Yanmar B22-2C fuse blows repeatedly, can't confirm which amperage cartridge to order p. 29
Check the fuse block layout in the Electrical System section on page 29. The parts list on page 32 shows the block carries cartridge fuses in three ratings: 5A (qty 1), 10A (qty 2), and 15A. Match the blown fuse's position in the block to the correct part number before ordering; installing the wrong amperage rating will cause repeated failures.
Manual Section: Electrical SystemWork lamp or headlight bulb burned out, unsure which replacement bulb part number fits p. 29
Locate the lamp assemblies in the Electrical System section on page 29. The parts list on page 34 confirms the work lamp takes a 12V-60W bulb and the headlight takes a 15V-60W bulb. Order by part number from the page 34 list and verify voltage before purchasing; installing a 12V-rated bulb in the headlight socket will cause premature burnout.
Manual Section: Electrical SystemHydraulic hose leaking at a fitting, can't find the correct replacement hose or O-ring part number p. 103
Identify which circuit the leaking line belongs to, then open the Hydraulic Oil Tank and Piping section on page 103. The diagrams cover sub-sections for Tank-Pump-Valve, Valve-Motor, Boom, Swivel-Swing, Return, P.T.O., and Travel circuits, each listing hose assemblies, clamps, O-rings, and adapter fittings as individual part numbers. Match your hose routing to the correct sub-section to isolate the exact part before ordering.
Manual Section: Hydraulic Oil Tank & PipingTrack roller, idler, or tension adjuster worn out, need to identify the correct undercarriage part number p. 38
Open the Undercarriage and Frame section on page 38. The Roller and Adjust exploded view lists each track roller, idler wheel, and tension adjuster as separate line items with individual part numbers. Note whether your machine is the cabin or canopy variant before ordering, as frame and cover components across pages 38-42 differ between configurations; confirm your build before submitting a parts order.
Manual Section: Undercarriage & FrameControl lever or travel pedal assembly damaged, can't match the broken piece to a part number p. 43
Turn to the Control Equipment section on page 43. The diagrams across pages 43-56 break the lever stand, travel pedals, swing control, blade control, PTO control, cut-off lever, and low-high pedal into individual sub-assemblies with part numbers. Identify the specific lever or pedal type first, find its sub-section, then order only the failed component rather than the full assembly to avoid unnecessary cost.
Manual Section: Control Equipment (Levers & Pedals)Hydraulic pump or boom cylinder internal component needed, can't identify the correct part by inspection p. 73
Find the hydraulic pump and cylinder breakdown in the Hydraulic Power and Drive section on page 73. The Hyd. Oil Pump and Joint exploded view and the Boom Cylinder diagram on pages 73-80 list pump housing components, port fittings, cylinder end caps, and joint hardware as individual part numbers. Cross-reference the parts index to confirm compatibility with your specific model variant (C, CR, P, or PR) before ordering internal components.
