An Annual Parts Budget and Purchasing Plan for Excavator Fleets
Hose and service lines we hold in stock
Filter elements ready for consolidation
Undercarriage wear parts staged for shipment
Every fleet has a parts budget whether it writes one down or not. The question is only whether it is spent deliberately — on scheduled service, at negotiated prices, consolidated into few shipments — or reactively, at short notice, with air freight and downtime included in the true cost. Corbay is the international export brand of Guangzhou Shenyue Machinery Technology Co., Ltd., Guangzhou, China. We supply fleets across 30+ countries, and the difference between a planned and an unplanned buyer is visible in what their orders look like: planned buyers send lists; unplanned buyers send emergencies.
Guangzhou Shenyue Machinery Technology Co., Ltd. stocks 3,000+ part types on the shelf with 100,000+ part numbers available to order, and the practical value of that stock position is not the shelf alone — it is that a plan can be executed quickly when an unexpected failure does happen. This guide sets out a planning method that works on fleets of five machines or fifty.
Bucket One: Scheduled Service
Filters, oils, greases and the consumables of planned maintenance. These are predictable, cheap per item and should never be bought in a hurry. The starting point is a service interval table per machine model and a count of hours each machine will run in the year. Multiply, and the annual requirement is known before the year starts. Service items are also the best candidates for consolidation, because they are small, cheap to ship and cover the whole fleet.
Bucket Two: Wear Parts
Bucket Three: Failure Risk
Pumps, travel and swing motors, final drives, turbos, injectors and electronics. These cannot be fully forecast, so they are handled differently: identify the failure modes your machine population is most exposed to, decide in advance what you will hold on the shelf versus order on demand, and pre-agree the identification details — machine serials, component plates, contact points — so an emergency becomes a confirmation rather than an investigation. A fleet that can send a plate photograph at 8 a.m. usually has the part quoted the same day.
The Consolidation Calendar
Once the three buckets are written down, the calendar writes itself. Schedule two or three main consolidated shipments a year for service and wear items, plus a standing arrangement for failure-risk parts. Then measure the obvious number: how many shipments the fleet actually needed versus how many were planned. Buyers who consolidate typically find that the freight saved on a single cancelled air shipment pays for a substantial part of their annual service consumables. Guangzhou Shenyue Machinery Technology Co., Ltd. supports this with per-shipment packing photographs and grades marked on every quotation line, so budgets can be compared against reality.
Review, Measure, Adjust
A plan that is never reviewed becomes a formality. Three numbers are worth tracking quarterly: hours run per machine, parts consumed per hundred hours by category, and the share of spend that went through planned orders rather than emergencies. The first tells you whether the fleet is working more than expected; the second exposes a machine aging faster than its siblings; the third is the single best indicator of whether the plan is actually being followed. Adjust the next consolidated order rather than the annual document — plans are corrected in orders, not in spreadsheets.
Cross-Brand Coverage in One Plan
Mixed fleets are the norm, and a plan that covers only one brand leaves gaps. Our supply covers Kobelco, Hino, Isuzu, Yanmar, Cummins, Kawasaki, Nabtesco, KYB and KPM through original supply channels, plus formal authorization for Mitsubishi (MHI engine parts), Garrett, TONGMYUNG, Marusan and NIKURA. For Kobelco SK-series machines specifically, model-level part numbers and diagnostics are published on the group's dedicated reference site, shenyuekobelco.com — useful when a plan needs to reference exact numbers rather than categories.
