The brief
The buyer sent us one thing: a listing for an M264 2.0T Engine Overhaul Rebuild Kit — crankshaft, connecting rods, pistons, bearings and the full gasket set — that his end customer wanted for a Mercedes-Benz W205. His problem was the same one we hear from importers every week: he could find sellers online, but he had no way to know who actually makes these kits, whether the part numbers would match, and what he would receive on the day the box opens.
He also had a clock running. His customer was ready to pay, but only after seeing proof.
Matching the kit to a factory we already knew
We didn't post this RFQ to a marketplace. The kit went to an engine-parts manufacturer already in our vetted network — a factory we had on record for Mercedes M-series engine components. Within one working day we had a quote where every line mapped to an OEM part number:
- Piston kit 2640301800 — STD 83.1 mm, rings and pins included, packed 1 CYL/Box
- Crankshaft 2640300101 — STD, 16.8 kg, hardness tested (the crate carries the HRC stamp and production date)
- Connecting rods — matched new set
- Crankshaft bearing set 2640330201 — STD
- Full gasket and seal set — valve cover gasket, head gasket, seals
No "compatible" substitutes, no vague descriptions. If a part number couldn't be matched exactly, we said so instead of guessing.
The evidence the buyer actually received
This is the part we believe no listing can replace. Alongside the quote, the buyer got photos of the actual production batch — his parts, on the factory bench, not a catalog render:
- Pistons with the STD size marking visible, photographed top and crown
- A connecting rod on the workbench, bearing bore and small end in view
- The crankshaft bearing set open in its box, shells in sequence
- The full gasket set, still in its packaging film
- Packing labels: part number, size, engine code (Eng: 264 2.0T), packing spec, barcode
Approval and the sourcing fee
The buyer forwarded the evidence pack to his customer. The customer approved, and paid the sourcing fee the same day. The buyer's message to us, unedited:
"I cannot tell you how amazing this new tool of yours is. So easy, professional — all the information in one place. It's amazing."
That "one place" matters. Instead of a chat thread with a stranger selling parts, he had one dossier: quote, part numbers, photos, packing plan. That is what we mean when we say the factory sees us and you see everything.
Packing and shipping
Goods were packed to survive the trip: pistons per cylinder in labeled cartons (1 CYL/Box), each label carrying the part number, size, engine code and a barcode. The crankshaft travels in its own strapped crate — 16.8 kg with the HRC hardness stamp on the lid. We then prepared both sea DDP and air DDP quotes so the buyer's customer could choose between cost and speed.
What this case actually proves
Not that we can "source anything from China" — anyone can type a product name into a search bar. This case shows the three things we do that a listing cannot:
- We already knew the factory. The match came from our vetted network, not a cold search.
- Every part number was verified before payment — against OEM references, with photos of the real batch.
- The buyer's customer paid on the strength of that evidence — the sale closed on documentation, not promises.
If you're importing engine parts, machinery components or anything where a wrong part number costs real money, this is the standard you should demand from whoever stands between you and the factory.
