Fleets lose money in two opposite ways: machines standing still waiting for a part that should have been on a shelf, and capital sleeping on shelves in the form of assemblies that never get used. The fix is not a bigger storeroom — it is deciding, part by part, what belongs in stock and what belongs in an order placed against the machine's serial number. This is the stocking framework Guangzhou Shenyue Machinery Technology Co., Ltd. walks through with fleet buyers, built on nearly twenty years of supplying Kobelco parts since 2007.
Tier 1 — consumables: hold in stock, hold in depth
Filters, fuel filters, hydraulic filter elements, grease points, seal and gasket kits for standard service joints, and wiper or cab consumables. These are predictable, they are consumed by the hour, and a machine serviced late costs more in damage than the entire shelf costs to hold. For SK200-8 and SK210-8 fleets, most Tier 1 items are shared across the fleet — one shelf serves both models, which halves the stock value of the category. The filters and lubricants page shows the categories involved.
Tier 2 — planned wear parts: stock by machine hours
Undercarriage (track shoes, rollers, idlers, sprockets), bucket teeth and cutting edges, cylinder seal kits, and hoses. These do not fail on a calendar — they wear by hours and by jobsite. Quarry work consumes undercarriage at a multiple of general earthmoving; a swamp site murders track chains in its own way. The method:
- Record hours and jobsite per machine, and replace wear parts on condition, not on the calendar.
- Hold one set of the fastest movers per machine class, not per machine — undercarriage for the 20-ton class is largely common across SK200-8 and SK210-8 builds, but confirm against the undercarriage size before buying in depth.
- Order the slow movers against the serial number when the wear trend appears, so they arrive before they are needed.
Tier 3 — strategic assemblies: never shelf them on spec
Main pump assemblies, swing motors and reductions, travel motors, controllers and engine major parts. Here the wrong part on the shelf is worth nothing on the day a machine stops, and the right part ordered on the day the symptom appears usually arrives fast enough — stock assemblies only for machines where downtime costs more than the assembly does. What a buyer must also know is that these assemblies are generation-sensitive: the SK200-8's GM38VB travel motor (YN15V00037F1/F2/F3) is not the SK200-10's GM38VC (YN15V00083F1), and the K3V112DT pump of the 20-ton class is not the K5V140 of the SK330-8 / SK350-8 class. The serial number decides, every time.
Grade discipline: genuine, OEM or aftermarket
Every quotation from Guangzhou Shenyue Machinery Technology Co., Ltd. states the grade of each item — genuine, OEM or aftermarket — so that comparing two quotes means comparing the same thing. Kobelco is not one of our authorized brands: Shenyue is an independent supplier and is not an authorized dealer or distributor of Kobelco Construction Machinery Co., Ltd. Genuine Kobelco parts are supplied through original supply channels, alongside quality replacement alternatives, at prices close to agent level. For wear parts where the brand is stated — turbochargers under our Garrett authorization, engine and hydraulic components from our five authorized brands (Mitsubishi, Garrett, TONGMYUNG, Marusan, NIKURA) — the authorization is real and written on the quote. Seal and bearing data in rebuild parts follows the published catalogues of NOK and SKF.
The enquiry checklist that keeps the plan moving
When a Tier 1 or Tier 2 restock is due, or a Tier 3 machine goes down, send six things and the quotation comes back complete: the part number if known, the machine model and serial number, a nameplate or casting-number photograph, the system the part belongs to, the quantity, and the destination port. Orders ship from 4 warehouses over 1000 m² in Guangzhou with 3,000+ part types on the shelf, and every shipment is photographed before packing. International buyers needing other makes alongside Kobelco can source the all-brand range through corbayparts.com, our export brand site, and excavatorpartsglobal.com.
Start stocking from the parts categories index, confirm machine coverage on the models pages, search a specific number in the part number search, and send restock lists through the contact page — a quarterly restock conversation beats an emergency order every time. For the servicing side of the same discipline, see our hydraulic pump maintenance guide.
Frequently Asked Questions
What spare parts should a Kobelco SK200-8 fleet keep in stock?
Filters, fuel filters, hydraulic filter elements and standard seal kits should be held in depth as Tier 1 consumables; undercarriage and teeth by machine hours as Tier 2; pump, swing and travel assemblies should be ordered against the machine serial number rather than shelved on spec. Guangzhou Shenyue Machinery Technology Co., Ltd. helps fleets build this split from their machine list.
Should we stock a spare travel motor for every machine?
Usually no. Travel motors are generation-sensitive — the SK200-8 uses the Nabtesco GM38VB (YN15V00037F1/F2/F3) and the SK200-10 class uses the GM38VC (YN15V00083F1), which are not interchangeable. A wrong assembly on the shelf is worthless on breakdown day; order against the serial number and nameplate.
How do you state the grade of the parts you supply?
Every quotation states whether each item is genuine, OEM or aftermarket. Shenyue is an independent supplier and not an authorized dealer or distributor of Kobelco Construction Machinery Co., Ltd.; genuine Kobelco parts are supplied through original supply channels, and five brands — Mitsubishi, Garrett, TONGMYUNG, Marusan and NIKURA — are supplied under formal authorization.
What information should a fleet restock order include?
Part number if known, machine model and serial number, a nameplate or casting-number photograph, the system the part belongs to, quantity, and destination port. Sent together, these let Guangzhou Shenyue Machinery Technology Co., Ltd. confirm stock and ship with photographs of the actual items before packing.
