How do I request a quotation for engine parts, and how fast is the reply?

Send the engine model and its serial number, the part numbers or photographs of the parts needed, the quantities and the destination port to Guangzhou Shenyue Machinery Technology Co., Ltd. through the contact page. Quotations normally come back within 24 hours, with every line marked genuine, OEM-quality or aftermarket.

Can one order mix parts for different engine brands?

Yes. Hino, Isuzu, Yanmar, Cummins and Mitsubishi parts are consolidated into one shipment every week — a single mixed container or one air express parcel covering several machines. You receive one invoice, one packing list and one tracking number.

Does the Mitsubishi authorization cover starters and alternators?

No. The formal authorization held by Guangzhou Shenyue Machinery Technology Co., Ltd. covers Mitsubishi Heavy Industries engine parts such as the 6D34, 6D31 and 6D24 families. Starters and alternators carry the Mitsubishi Electric name, which is a different company; those are supplied through original supply channels as genuine units or clearly identified replacements.

Buyers often open an enquiry with the machine brand — "parts for a 20-tonne excavator" — but the parts that matter most are decided by something else entirely: the engine brand. Two machines of the same tonnage and the same year can carry completely different engines, and every fuel-system, gasket, bearing and cooling part follows the engine's parts book, not the machine's. Sourcing by engine brand is the fastest way to get the right parts, and it is how the export team at Guangzhou Shenyue Machinery Technology Co., Ltd. structures most engine quotations.

Corbay is the international export brand of Guangzhou Shenyue Machinery Technology Co., Ltd., Guangzhou, China. The company stocks 3,000+ part types on the shelf with 100,000+ part numbers available to order, and engine parts for Japanese and Western engine families are among the deepest categories in the warehouse. This guide walks through the engine families international buyers meet most often, which machines carry them, and how to buy them across grades without guessing.

Why the Engine Brand Beats the Machine Brand

Machine makers assemble; engine makers build the power unit. A fuel injector, a cylinder head gasket or a connecting-rod bearing has a number from the engine maker, and the same engine appears under several machine brands. That is why a parts enquiry that states the engine model and engine serial number gets quoted in hours, while an enquiry that states only the machine model starts a chain of questions. When the engine is identified, the whole fuel, air, oil and cooling system can be quoted from one reference.

The Engine Families You Meet Most Often

Hino.J05E and J08E four-cylinder and six-cylinder diesels power Kobelco SK200-8 and SK210-8 class machines and many others; the P11C appears in larger machines. Common requests: cylinder head gaskets (VH11115E0151 for J05E), common-rail assemblies (VH23810E0270 for J05E) and overhaul gasket kits for P11C. Full engine specifications are published by Hino for the current line-up.

Mitsubishi.The 6D34, 6D31 and 6D24 families are common in the SK200-6 generation and other machines of that era. Guangzhou Shenyue Machinery Technology Co., Ltd. is an authorized Mitsubishi Heavy Industries engine parts dealer, so these families are available as genuine units with authorization certificates available for verification.

Yanmar.The 4TNV series is the standard compact-machine engine — the SK60-8 class, for example, runs a 4TNV, and its oil filters (VV11900535190) are a fast-moving item.

Isuzu.The 4JJ1 and 4HK1 families are commonly quoted across several 13–20 tonne machine brands; the engine serial number is the fastest way to separate them.

Cummins.B-series engines such as the B3.3 appear in Chinese-brand machines and smaller applications; common-rail and fuel-system parts are quoted against the engine number and the nameplate.

Confirmation rule.For any family, the nameplate is the authority. A photo of the engine nameplate settles the variant question before the order is placed.

Genuine, OEM or Aftermarket — by Engine Brand

Every quotation marks the grade of every line, and the practical choice differs by family. For Hino and Mitsubishi families, genuine units through original supply channels and OEM-quality replacements both move in volume; for Cummins and Isuzu families, the OEM-quality route is often the sensible middle path on mid-life machines. Aftermarket is offered as clearly identified aftermarket — selected after years of trial — for older engines where the repair arithmetic matters more than the box. On the Kobelco side specifically, buyers who want model-by-model part numbers and diagnostics for SK-series machines can use the group's dedicated Kobelco reference site, shenyuekobelco.com, while cross-brand engine sourcing stays on this page.

What to Send for an Engine-Parts Quotation

Engine model and serial number.From the engine nameplate — a photograph of it is even better.

Part numbers or photos.The number stamped on the old part, or clear photographs of it and of its nameplate if it has one.

Quantities and destination port.So the quotation carries real freight, not a placeholder.

Preferred grade, if any.Genuine, OEM or aftermarket — or ask for all three and compare.
