Cab, canopy, EC and export builds of the Kobelco SK045-2 hydraulic excavator are all broken out in this 508-page Kobelco SK045-2 parts catalog PDF, OEM ID S4PY1008. Engine parts take up roughly the last quarter of the book, from crankcase and cylinder head to timing gears and fuel supply, while the hydraulic components section explodes the control valve and pump assembly right down to the shims. Every exploded view ties a callout to a Kobelco part number, so you can match the upper harness, track rollers, idler adjust assembly, swing bracket or a 1.45 m breaker arm without guessing at the parts counter. Before ordering, confirm your replacement main relief valve carries the 210 kgf/cm² at 55 L/min setting, not the 240 kgf/cm² port relief. Order the wrong valve and the crew waits on freight. Bookmarks jump straight to each group, and the pages print clean enough to clip above the bench and get greasy.
