A motorcycle crankcase pair can arrive with the correct-looking title and still leave a wholesale buyer with open questions: are both sides present, does the received code match the approved quote, and do the listed measurements describe the part or its package? A simple receiving record helps a distributor catch mismatches before the lot is mixed into stock.
Quick answer: receive each crankcase order against its approved line item. Match the buyer reference, supplier code, exact vehicle version, left/right sales unit, count, labels, visible condition and agreed drawing. Photograph the carton and parts, keep uncertain items on hold, and ask the supplier to confirm any discrepancy in writing. A catalogue title or photo alone does not establish fitment or full set contents.
Why should crankcase stock be checked against the approved order?
Crankcase listings can combine a model family, a seller reference and a sales-unit description. Those fields answer different questions. The model name describes an intended application, a supplier code identifies the offered item, and “pair” or “set” describes a sales unit only to the extent the quotation defines it.
For wholesale receiving, the useful comparison is not just “does the box look right?” It is whether the item, variant, quantity and evidence match the line the buyer approved. This matters most when several similar engine cases, model years or market versions arrive in the same shipment.
What eight checks belong on a crankcase receiving sheet?
Use one record for each buyer line and each distinct supplier option. Keep original references as received, then record the receiving result beside them instead of overwriting them with a guessed match.
| Check | Record at receiving | If it does not match |
|---|---|---|
| 1. Order identity | Buyer line ID, supplier SKU or reference, purchase-order line and carton/lot label. | Photograph each label and hold the affected line for supplier confirmation. |
| 2. Vehicle version | Make, model, year, destination market and engine/frame code that were supplied for the quote. | Mark application as “pending”; do not treat a broad model name as final fitment proof. |
| 3. Left/right scope | Whether the approved sales unit is a left-and-right pair, one side, or another defined set; count the physical pieces. | Keep both the quoted unit and received count visible in the discrepancy record. |
| 4. Included contents | Only the components named in the quote or approved packing list; record unlisted parts separately. | Do not assume bearings, dowels, covers or other items are included because they appear in a reference image. |
| 5. Markings and traceability | Readable cast/stamped marks, supplier labels, carton IDs and any lot or batch number. | Use “not present” or “not legible”; never create a replacement part number. |
| 6. Visible condition | Photographs of the carton before opening, protective packing, both case halves and any visible damage. | Keep the packaging, isolate the item and send dated photos before cleaning or altering it. |
| 7. Drawing comparison | Approved drawing revision, named measurement points, units and the tolerance agreed for that item. | Ask for a controlled drawing or written measurement method; do not invent a pass/fail tolerance. |
| 8. Quantity and pack-out | Pairs/sets per carton, cartons received, quantity per line and the packing list used to count them. | Reconcile the count by line and carton before combining stock from different lots. |
How do you keep application evidence separate from seller wording?
Store the requested vehicle details, the supplier’s offered code and the source of each fitment statement in separate fields. If a seller lists several applications, copy the wording as a seller claim and ask which exact engine version and market it covers. A shared model name or matching reference string does not, by itself, prove interchangeability.
One VOBOM catalogue page is titled as a left-and-right crankcase set for a listed 4-valve WAVE125 configuration. Its description also identifies seller-listed applications and says that exact engine version and mounting compatibility have not been independently confirmed. Treat that as a prompt for a written fitment review, not a universal compatibility statement. See the WAVE125 crankcase pair listing.
For a pre-order cross-reference workflow, see the motorcycle parts cross-reference guide. It keeps the buyer’s ID, supplier SKU, application and evidence status distinct; the receiving sheet can continue that same record after delivery.
Can catalogue dimensions be used as crankcase inspection limits?
Only when the supplier states what those dimensions describe and provides the measurement basis. A row such as “25 × 20 × 20 cm” may refer to an item, a package or an unspecified listing field; without scope, it is not a machining specification, a fitment limit or a confirmed carton size.
Before a bulk order, ask for an approved drawing or a written table that names each datum, the measurement points, units and acceptance tolerance. Compare the received item using the same method. If the supplier has not supplied a drawing or tolerance, record that field as “not provided” and request clarification instead of deciding from a photograph.
What should happen when a receiving check finds a mismatch?
Give the issue a clear status: received and matched, confirmation requested, or held for buyer review. Identify the affected buyer line and quantity; do not mix it with a different option while the question is open. Save the outer-carton label, inner labels, the relevant part marks, a wide photo and close-ups that show the concern.
Send the supplier the approved quote or drawing revision alongside the receiving evidence. Describe what differs without assuming the cause—for example, “one side missing from a line quoted as a pair” or “marking differs from the approved reference.” Ask for a written disposition before the part is installed, modified or released to stock. This guide covers procurement records, not repair or installation instructions.

What information should a buyer send before the next order?
Use the receiving record to improve the next RFQ. Include the buyer line ID, exact supplier code, intended make/model/year/market, engine or frame code if available, required sales unit, quantity per option and destination. Attach the approved drawing or sample reference and request the seller to list included contents, package scope and current commercial terms.
For the WAVE125 example, ask the supplier to confirm the exact engine version, the applications covered by its evidence, the left/right set contents, the scope of any listed dimensions and the current availability and quote. Keep freight separate until the packed quantity, confirmed carton data and destination are known.
Frequently asked questions
Does “left and right crankcase pair” mean every related engine part is included?
No. The phrase identifies the pair only as described by that listing. Ask the supplier to enumerate the items included in each sales unit and compare the answer with the approved quote and packing list.
Does a seller-listed WAVE125, W100 or WAVE110 application confirm fitment for every year?
No. A seller application label is not proof for every engine version or market. Provide the exact year, market and engine code, then request a written response for that specific option.
Can the catalogue’s package measurements be used to book freight?
Not unless the supplier confirms that they describe the packed carton and supplies the matching gross weight. Ask for the carton count, outer dimensions and gross weight for the actual order quantity and destination.
What should be retained when a part is placed on hold?
Keep the purchase-order line, supplier code, carton and lot labels, count, dated photographs, approved drawing revision and the written supplier response together. This makes the question traceable without changing the original reference.
Next step: Review the listed crankcase pair and send the exact engine version, quantity and destination through VOBOM’s motorcycle sourcing inquiry. Ask for current fitment, included contents, availability, packing and freight to be confirmed in writing for your order.
