Kobelco SK460-8, SK500-10 and SK550-10 Parts Guide: The 45-50 t Class Service List

Kobelco's 45 to 50 tonne class is a different world from the 20 tonne machines most guides are written about. The SK460-8, SK500-10, SK495D and SK550-10 work in quarries, mass excavation and heavy civil projects, frequently on two or three shifts, and an hour of downtime costs far more than it does on a 20 tonner. That changes the buying logic: the parts that matter are the ones that keep the machine cutting, and the number has to be right the first time. Guangzhou Shenyue Machinery Technology Co., Ltd. supplies this class from a shelf built around it.

How this class differs from a 20 tonne machine

Three differences shape the parts list. Displacement: pumps, motors and cylinders are physically larger, so a filter or hose from a 20 tonne machine is never a substitute. Thermal load: both the engine and the hydraulic system reject far more heat, putting the oil cooler, radiator and return filtration under real pressure. Duty cycle: these machines spend more hours at load, so consumable intervals compress.

The practical consequence is that large-class buyers replace cooling components and return filters far more often than they expect, and they buy engine filter groups in sets rather than one at a time.

The engine side: P11C and the filter group

The SK460-8 is associated with the Hino P11C engine family, and the service group is where most of the routine money goes. These are live rows from our own shelf:

Note how many references sit inside one oil filter line. On this class the same element is sold under several numbers depending on which packing house boxed it, so a quotation listing only the first number can look like the wrong part when the carton arrives. Quote them all, and put the full string on the purchase order.

Hydraulic side: return filtration, sensors and the slewing ring

Return filtration on a 45 tonne machine is a wear item in the truest sense, and the cheapest insurance in the hydraulic system. A short list from stock:

• Return filter — LS52V01006R210 / LS52V01006R200, catalogued for R200, R210 and SK495D.
• Hydraulic oil temperature sensor — LS52S00046P1, catalogued for SK220-10 and SK500.
• Slewing ring — LC40F00027F1, catalogued for SK380-10; the very largest machines carry their own ring, so confirm by serial.

A drifting oil temperature reading does not simply misinform the operator: it changes how the machine de-rates and how the oil is judged at service. Replacing a sensor is trivial next to the consequences of ignoring one.

Why the same number rarely crosses classes

A 50 tonne machine's return filter passes a much larger flow than a 20 tonne machine's. Physically similar cartridges are not the same cartridge, and a filter that goes into bypass is worse than no filter at all, because it releases what it was holding straight into the components downstream. Cross-class substitution is one of the most expensive ways to save a few dollars.

Buying this class without a stock-out

The mistake we see most often is ordering single elements against a breakdown instead of sets against a service plan. Buying a quarter's consumption at once costs less per unit and, far more importantly, removes the risk of a machine sitting idle waiting on an element that weighs two kilograms.

Guangzhou Shenyue Machinery Technology Co., Ltd. has specialised in Kobelco parts since 2007, with 4 warehouses over 1000 m² in Guangzhou, 3,000+ part types on the shelf and 100,000+ part numbers available to order through original supply channels. Shenyue is an independent supplier of excavator parts and is not an authorized dealer or distributor of Kobelco Construction Machinery Co., Ltd.; for Kobelco, Hino, Isuzu, Yanmar, Cummins, Kawasaki, Nabtesco, KYB and KPM we supply genuine parts ordered through original supply channels alongside quality replacement alternatives, at prices close to agent level, and the five brands we hold formal authorization for — Mitsubishi, Garrett, TONGMYUNG, Marusan and NIKURA — are named on every quotation. See the class pages for the SK460LC and SK500LC, browse filters and lubricants, and read the engine P11C reference data published by Hino.

Frequently Asked Questions

Which engine family do Kobelco SK460-8 parts belong to?

The SK460-8 is associated with the Hino P11C engine family. Our oil filter line VH15601E0070J2M / LS30T01001P1 / VHS156072281 / VHS156072360 / VHS156072150 / VH15601E0230 and the fuel filter VHS234011640J1M are both catalogued for P11C and SK460-8. Guangzhou Shenyue Machinery Technology Co., Ltd. confirms the engine from the plate before quoting, because second-hand machines can carry a service group that does not match the model year.

Can I use a 20 tonne machine's return filter on a 50 tonne Kobelco?

No. Return flow scales with machine size, so a cartridge sized for a 20 tonne machine will open its bypass on a 45-50 tonne machine and release the contamination it was holding into the pumps and motors downstream. The large-class reference we hold is LS52V01006R210 / LS52V01006R200, catalogued for R200, R210 and SK495D, and it must be confirmed against the housing on your machine.

What should a large-class Kobelco service order contain?

Send the machine serial and engine model from the plate, a photograph of each filter housing, and your destination port. For a two-shift quarry machine we quote a quarter's filtration rather than single elements: the per-unit cost is lower and the machine never waits on a filter. Genuine, OEM-quality and aftermarket options are listed as separate lines on the same quotation.

How do I know whether my Kobelco needs LC40F00027F1?

Only by serial. LC40F00027F1 is the slewing ring we hold catalogued for the SK380-10, and the largest machines carry their own ring rather than a shared one. Send the serial and a photograph of the ring's stamping, and the number is confirmed against the unit instead of assumed from the model name.
