Kobelco's own part numbers for the SK13SR hydraulic excavator, the ones a generic aftermarket listing can only guess at, are settled in this 320-page factory parts catalog, OEM ID S3PE00001ZE04. Exploded views in the Kobelco SK13SR parts catalog PDF split the machine into superstructure, undercarriage and attachment groups. The slewing motor, crawler idler and idler adjuster, track rollers, dozer blade, and boom and arm hydraulic lines each get their own figure with numbered callouts. Harness assembly drawings cover the electrical side. A filter list, a nut and sleeve reference and a parts name index let you cross-reference a component when all you have is its name. Order the fuel system O-ring as 24311-240100 (size 1A P-10A) and the 8S seal washer as 22190-080002. Guessing a seal washer size by eye wastes a morning. The PDF is bookmarked and has a text layer, so your copy goes on a laptop or phone to whatever site the machine is working.

Kobelco SK13SR Common Problems This Manual Covers
Kobelco SK13SR 3TNE68 main bearing part number unclear for undersize 0.25 mm crankshaft journals
Check the Cylinder Block parts list on page 279, where the standard main bearing and the under-size main bearing (U.S=0.25, 0.25 mm) appear as separate lines, quantity 4 each. Pull the thrust bearing (quantity 2) and the cylinder head gasket from the same page so the block order is complete in one shot.
Manual Section: Cylinder Block p. 279Crankpin bearing and oversize piston ring set part numbers hard to find for engine rebuild
Open the Crankshaft & Piston parts list on page 291. The crankpin bearing is listed in standard and U.S=0.25 under-size, while the piston assembly and ring set are listed in O.S=0.25 over-size, quantity 3 each. Read the remarks column codes, (2) under-size and (3) over-size, before you place the order.
Manual Section: Crankshaft & Piston p. 291Engine lube oil filter and switch (oil pressure) replacement part numbers hard to locate
Check the filter list in General Maintenance Items starting on page 15, then confirm it against the Lubrication Oil System parts list on page 293. That page lists the lube oil filter, the oil pump assembly and its gasket, the dipstick, the oil pressure valve assembly and the switch (oil pressure). Add the oil intake pipe O-ring to the same order.
Manual Section: Lubrication Oil System p. 293Cooling water system thermostat, V-belt and radiator cap part numbers hard to match
Pull up the Cooling Water System exploded view on page 294 and its parts list on page 295. The list covers the C.W. pump assembly with gasket and O-ring, V-belt, fan, thermostat with cover and O-ring, radiator cap, sub-tank cap and the 110°C thermo switch. Match each reference number on the drawing to the list before you order.
Manual Section: Cooling Water System p. 295Fuel injection valve seal washers and fuel line O-rings needed, correct size unclear
Check the Fuel Injection Valve parts list on page 301, which shows seal washer 14S as part 22190-140002, quantity 3. Page 303 lists O-ring 1A P-10A as part 24311-240100 and seal washer 8S as part 22190-080002, quantity 2. Order these sealing parts together so the job is not held up by one missing washer.
Manual Section: Fuel Injection Valve p. 301Valve stem seals and bonnet gasket part numbers needed for cylinder head reseal
Check the Cylinder Head & Bonnet parts list on page 285. It shows the valve stem seals and valve guides (quantity 6 each), the nozzle gaskets, the bonnet gasket and the glow plugs, and it flags the valve guide as a repair part. The head gasket is in the Cylinder Block list on page 279, so build your order from both pages.
