How to Order the Right Truck Parts: Our 4-Step Confirmation Process

Ordering the wrong spare part costs everyone time: a week of shipping, a machine standing still, and a second order. That is why we do not treat an inquiry as a simple price request — every order goes through a confirmation process before we quote and ship.

Below are the four methods we use to confirm exactly which part you need, listed from the fastest to the last resort. In most cases, step 1 alone is enough.

Method 1 — Part Number or Clear Photos (works for ~80% of inquiries)

The part number is the most reliable identifier in the industry. It is usually a combination of letters and numbers, and you can find it on:

the surface of the old part itself (cast, stamped or etched)
the packaging box or label
the parts catalogue / content book of your machine
a quotation list from your local distributor

Every spare part has a unique part number, and it removes almost all guesswork — so if you can find it, send it first.

Cast part number 183070209647 stamped on the surface of a used truck component — A part number cast directly onto the surface of an old component — highlighted in paint for the photo. This single number is enough for us to locate the item in our catalogue.

Used hydraulic gear pump photographed as an identification reference for spare part matching — No number readable? A clear photo of the complete unit — like this gear pump — works too: keep the label, shaft and mounting face all visible.

Tip: no part number? Send 2–3 clear photos instead: one overall shot, one close-up of any numbers or logos, and one of the mounting side. Daylight, no flash, and a coin or ruler in frame helps us judge size.

Method 2 — Vehicle Information

If the part number is unavailable (common with dealer-only items or worn-away markings), we search our system using your machine data:

engine nameplate details (model, serial number)
assembly / transmission nameplate
VIN or chassis number
machine model and year

With these we trace the original bill of materials and propose the matching part. If two variants fit the same model, we will tell you which one applies to your serial range.

SEM 655D wheel loader machine nameplate showing model, engine model and product identification number — Real example: a wheel loader nameplate. Model SEM655D, engine model WD10G220E23, and — the most useful line — the **Product Identification Number (PIN) SEM00655ES550809**. That PIN alone tells us the exact build configuration of your machine.

Weichai WP13G530E310 diesel engine nameplate with model, order number and serial number — An engine nameplate works the same way: model, order number and serial number are all we need to trace the parts fitted to this engine.

Method 3 — Measuring the Old Part

When neither the number nor the vehicle data can identify the part, we measure. You send us the dimensions of the part being replaced, and we match them against factory specifications. Typical dimensions we ask for:

Part group	What to measure
Undercarriage (track, roller, idler, sprocket)	link pitch, width, number of links, bolt hole spacing, roller OD and height
Hydraulic cylinders / seals	bore diameter, rod diameter, stroke, seal cross-section
Pins, bushings, bearings	outer diameter, inner diameter, length, flange thickness
Filters	height, outer diameter, thread size, seal diameter

A photo of the tape measure against the part is usually enough — no need for a formal drawing.

Measuring the diameter of a used flywheel with a tape measure for spare part identification — A tape measure across an old flywheel — one photo like this gives us the diameter to match against factory specifications.

Method 4 — Drawing or Physical Sample

This is the route for rare items, discontinued parts, or components that have to be specially manufactured. Send us a dimensional drawing — or, for complex hydraulic parts, a physical sample — and our factory produces to match. This takes longer and costs more, so we only go here when the first three methods genuinely cannot identify the part.

SANY SKT90SRT rear axle exploded parts drawing with the required item highlighted — A page from a SANY SKT90SRT rear-axle parts book, with the required item (pos. 2) highlighted — the drawing code at the bottom lets our factory match it exactly.

What we need from you — quick checklist

Part number (if available) or clear photos
Machine model, and VIN / chassis / engine serial if you have it
Quantity required
Delivery city and port (so we quote the landed cost correctly)

Why we insist on confirming first: a mis-identified part is not just a return — it is downtime on your site, customs paperwork to redo, and a second shipment. Ten minutes spent confirming beats two weeks of correcting.

Frequently asked questions

What if I cannot find the part number anywhere?

Send clear photos of the old part instead — an overall shot, a close-up of any markings, and the mounting side. If that is still not enough, we will move to vehicle information or measurements.

Which identification method is the fastest?

The part number. It is unique to the item and lets us confirm price and availability immediately, usually on the same working day.

Can you supply parts for SANY, SEM, Weichai and similar Chinese machines?

Yes. We supply undercarriage, engine, transmission, hydraulic and electrical parts for Chinese heavy trucks, wheel loaders and mining equipment, sourced from the original and OEM production lines.
