Can you identify an excavator part from a photograph?

In most cases, yes. A clear photograph of the part, of any number stamped or printed on it, and of the machine data plate is usually enough to narrow an unknown item to one or two candidates. Guangzhou Shenyue Machinery Technology Co., Ltd. provides this identification at no charge, whether or not the enquiry leads to an order.

What is a supersession and why does it matter to a buyer?

A supersession is the replacement of one part number by another over the life of a machine. A part can be listed as discontinued and still be perfectly available under its new number. A supplier who cannot trace the chain will tell you the part no longer exists; a supplier who can will quote the current number instead.

How long does a parts identification take?

Straightforward enquiries with a legible number or a good nameplate photograph are usually answered the same working day. Items requiring a parts-book search through several build ranges, or a factory check, legitimately take longer — and a good supplier tells you which category your enquiry falls into.

How Parts Identification Works at Shenyue

This is the part of the business customers never see. Somewhere between the email arriving and the price being quoted, somebody has to work out what the machine actually needs — and often the part number is unreadable, the plate is missing, or the machine was built in a year nobody has documentation for. Corbay is the international export brand of Guangzhou Shenyue Machinery Technology Co., Ltd., Guangzhou, China. This is how that work gets done.

What Arrives at the Desk

Five kinds of enquiry land on the desk every week, and only the first one is easy:

A clean part number.The straightforward case: number matches the catalogue, stock is checked, price returned with the grade stated.

A partly worn number.Four digits readable, three missing. Cross-referenced against the machine's build range and the catalogue until it resolves to one candidate.

A photograph only.No number, no book. Identification runs on shape, mounting pattern, connector type and position on the machine.

A superseded or discontinued number.The item exists under a different number. Nearly always solvable — but only with the right references in front of you.

A symptom instead of a part."The machine loses power when hot." The desk turns that into a list of likely components and a set of questions.

The Six Steps From Photograph to Order Line

1Intake and triage.Machine model, serial number and the symptom, separated from the assumption about what is broken. Buyers routinely arrive with a diagnosis already attached; the useful part is the observation underneath it.

2Parts-book lookup.The machine is matched to its build range and the relevant section of the parts book is opened. This is where a serial number earns its keep: the same model name covers several builds with different components.

3Supersession tracing.If the number in hand is old, the chain is followed forward to the current number rather than declared unavailable.

4Cross-reference against our own catalogue and stock.An identified part is only useful if it can be supplied. Stock, factory availability and the grades obtainable are checked at the same time as the number.

5Written confirmation.The reply states the part number, what it fits, the grade of each option, the price and the lead time — in writing, so the customer can check it against their own machine before money moves.

6Archive.Machine details stay on file. The next enquiry from the same customer starts from a known machine rather than a blank page, which is why repeat customers get faster answers.

Who Does the Work

The desk is staffed by technicians rather than salespeople, and that is deliberate. A salesperson without parts books will quote whatever the customer names; a technician will tell them what the machine actually takes. Each member of our technical team has more than ten years working with Kobelco and HINO parts, and the habit they share is a refusal to quote from memory.

The reason is the founder's background. Robbin Chen (陈剑国) spent 2002 to 2007 inside Kobelco as technician, warehouse manager and service manager, then started this business in 2007 with that experience as its entire capital. Shenyue took its formal name in 2011, and Corbay became the dedicated international export brand in 2021 — the same building, the same core team, the same four warehouses covering more than 1,000 m², holding more than 100,000 part numbers across more than 100 brands and shipping to customers in more than 30 countries.

Working from the manufacturer's own published material is the discipline behind every identification; the machine maker's own documentation is the starting reference for anything we cannot place from our own catalogue. We are an independent parts specialist and not an authorized Kobelco dealer — we say so plainly, and we work from the same parts books as anyone else.

Why Identification Is Free

We identify parts at no charge, including for enquiries that never become orders, and the reason is not generosity. It is the most efficient marketing this business has ever used. A buyer who has been helped with an unreadable number remembers who did it. Nearly twenty years of repeat customers across more than 30 countries were built substantially on answers that cost us nothing but time — and it filters out enquiries we could not serve properly anyway, which saves everyone a delay.

What the Desk Will Not Do

Pretend a discontinued part is available.If the honest answer is that a number is gone and a used or reconditioned alternative is the only route, that is the answer the customer receives.

Recommend the expensive option by default.On a machine with a defined remaining life, the cheaper grade is sometimes the correct advice, and we will say so.

Guess at a fitment.A guess that ships is a returned shipment, a lost week and a damaged relationship. It is not worth the sale.

Parts Identification — FAQ

How do I send an enquiry?A part number if you have one, plus machine model, serial number and photographs. Our enquiry checklist lists the eight items that produce a same-day answer.

Do you identify parts for machines you did not supply?Yes. Machines supplied by anyone are welcome; identification is based on the machine, not on its history with us.

Can you identify a controller or monitor?Yes — label and connector photographs are the reference material, and controllers are among the items we are asked about most often.

Send the Photograph — Let Us Do the Reading

If a number is unreadable or missing, send the photographs anyway. Our team at Guangzhou Shenyue Machinery Technology Co., Ltd. will do the cross-referencing and come back with a confirmed order line, the available grades and a lead time.
