Spare parts: keep identification ahead of quantity

Identify spare parts before deciding how many belong in a sale lot. A large quantity of uncertain parts may be less useful to a buyer than a smaller, well-documented set for a known machine.
Keep the part number exactly as marked, including suffixes and revision details. Similar references can describe different versions. Do not shorten a number because the difference looks minor.
Make a part-to-machine matrix
| Part reference | Description and evidence | Machine relationship | Status |
|---|---|---|---|
| Exact original reference | Packaging, markings and supplier record | Documented model or serial applicability | Identified |
| Substitute reference | Supplier or manufacturer confirmation | Stated replacement scope and limits | Confirmed substitute, if evidenced |
| Superseded reference | Original and successor information | Compatibility conditions still to check | Hold pending clarification |
| Unmarked or uncertain part | Physical description and source history | No verified match | Unidentified |
| Used spare | Identity plus service or removal history | Intended application to investigate | Condition stated separately |
The matrix is a record of evidence. It does not provide engineering approval for fitting the part.
Distinguish identity from condition
An original, correctly identified spare can still be damaged, used or poorly stored. Record seals, packaging, corrosion, missing components and any inspection evidence separately.
"New old stock" should not conceal that storage history is unknown or a consumable element may have a date limit. State what is actually established: unused according to specified records, unopened packaging observed, or condition not assessed.
The small-components guide covers count and mixed-bin problems. Use it when a parts reference has been spread across several containers or mixed with similar items.
Ask a focused compatibility question
Provide the part reference, photographs and the machine's exact model and serial details. Ask the manufacturer or appropriate supplier whether the documented application covers that combination.
Do not rely on "fits most machines of this brand". A service bulletin or replacement note may have conditions that matter. Keep those conditions with the sale record.
HSE's maintenance guidance supports using the right information and competence for equipment work. The sale catalogue should preserve that information rather than imply that a visually similar substitute is suitable.
Decide whether parts stay with a machine
Use the warehouse spares guide where the parts belong to handling or packaging equipment. A useful package can include identified spares, manuals and tooling that the buyer would otherwise have to trace separately.
For mixed maintenance stores, the stores triage guide distinguishes retained-machine reserves from sale stock. Obtain the business's approval before allocating every spare to a departing asset.
Do not split a documented kit accidentally. If only part of the kit remains, identify the missing elements instead of presenting the original kit number as a complete set.
Preserve evidence through collection
Keep labels and relevant packaging with the parts. Tie loose components to the lot reference without obscuring original identifiers. Record quantities by full sets, individual pieces and incomplete packages as appropriate.
Where the stock is relevant work equipment or components supplied in Great Britain, HSE's second-hand guidance provides safety and information context. Specialist questions about a part's intended use remain distinct from a simple count.
Send the matrix to UK Auction Group with photographs and proposed machine links. Clear identity gives buyers something specific to investigate and prevents a promising-looking stores clearance from becoming a list of unsupported compatibility claims.
