The 10112780 Starter Assy should be matched by verified application details, not by part number alone. Before ordering, compare the original unit’s identification, vehicle or equipment configuration, electrical system, mounting interfaces, pinion and terminal layout with the proposed replacement. A cross-reference is a useful lead, but it is not proof of direct interchangeability unless the relevant specifications and application are confirmed.

This guide explains how I recommend checking fitment, assessing cross-reference information and preparing a B2B sourcing inquiry. Because the exact application and specification for a part number can vary by catalog or supplier, I avoid assigning the 10112780 Starter Assy to a particular vehicle, engine or voltage without supporting documentation.
This guide is intended for parts distributors, importers, fleet maintenance teams, repair networks and purchasing professionals evaluating a replacement starter assembly. It is also useful when a buyer has received a cross-reference from a catalog or supplier but needs to verify whether it applies to the unit in hand. The steps below help reduce avoidable mismatches before a purchase order is issued.
For procurement teams, fitment is only one part of the decision. Documentation, order quantity, packaging, lead time and the supplier’s ability to clarify technical questions also affect whether a sourcing option is practical. I recommend resolving these points before treating any alternative number as an approved replacement.
A cross-reference connects one identifier to another in a parts database or supplier record. Depending on its source, it may indicate an equivalent replacement, a superseded number or a possible application match. The entry alone may not show whether every mounting, electrical and engagement detail is identical.
For the 10112780 Starter Assy, ask what the cross-reference represents and which application it covers. A number associated with a similar starter family may still differ in configuration or intended fitment. Treat catalog information as a screening tool, then verify the physical and electrical details against reliable application records or the original component.
Start with the complete number on the original starter, including any suffixes, labels or manufacturer markings. Record the vehicle or equipment make, model, year, engine identification and market or region when available. These details can help distinguish applications that may appear similar in a broad catalog listing.
Photograph the starter from several angles, including its mounting flange, pinion, terminals and any nameplate. If the original unit is unavailable, collect the application information from the equipment identification plate and maintenance records. Do not infer an exact replacement solely from a visual resemblance.
A reliable comparison considers the starter as a complete assembly rather than as a part number in isolation. The following checks are practical starting points, but the exact values must come from the original unit, application documentation or supplier-confirmed product specifications. If any essential detail is unknown, mark it as unverified rather than filling the gap with an assumption.
| Check | What to compare | Buyer action |
|---|---|---|
| Electrical system | Rated voltage, terminal arrangement and connection type | Confirm the equipment’s system voltage and compare it with the starter’s stated rating. Vehicle electrical systems commonly use nominal 12 V or 24 V, but the correct value for this application must be verified. |
| Mounting interface | Flange shape, bolt locations, register and orientation | Compare the original and proposed unit drawings or measure the relevant dimensions in mm. Check both the spacing and the locating features, not just the overall outline. |
| Pinion and engagement | Tooth count, pinion geometry and engagement position | Record the original configuration and request confirmation that the replacement engages correctly with the intended ring gear. |
| Connections and clearance | Terminal positions, connector style and surrounding space | Check cable reach, installation access and potential interference with nearby components. |
| Application identity | Equipment, engine and production configuration | Provide the most specific application details available and ask the supplier to state the basis for its fitment recommendation. |
Read the number directly from the existing starter where possible and retain a clear photo of the marking. Check whether 10112780 appears as the complete number or as part of a longer code. If markings are damaged or incomplete, share the available characters and images rather than guessing the missing information.
Record the equipment and engine details that a supplier can use to check fitment. Include model year or production period when known, since application records may distinguish configurations by build date or market. If you cannot identify the engine, explain that limitation and provide the equipment data plate details.

Use the original starter, an approved drawing or confirmed specifications to compare the mounting interface, electrical connections and pinion arrangement. Ensure measurements are taken from equivalent reference points and recorded in mm where applicable. A general visual match is not enough to confirm that mounting and engagement will work.
Ask the supplier to identify the reference source and clarify whether the proposed number is a direct replacement, a supersession or a possible match requiring further checks. Request a specification sheet, drawing or other available product information for comparison. If the supplier cannot verify a critical interface, keep the item in the conditional category until the information is resolved.
Before ordering, confirm the agreed part number, application, electrical specification, included components, packaging and commercial terms in writing. For repeat orders, retain the approved information with the purchase record so later replenishment is based on the same specification. This process helps purchasing, warehouse and technical teams work from a consistent reference.
Price and availability for the 10112780 Starter Assy depend on the confirmed specification, order quantity and supplier’s current terms. I recommend requesting a quotation only after the application and cross-reference status are clear, or stating explicitly which details remain pending. That makes it easier to compare offers on the same technical basis.
Ask each supplier to quote the minimum order quantity, price basis, packaging, estimated lead time and any sample or evaluation options. Confirm whether quoted timing refers to production, dispatch or estimated delivery, and whether the offer is subject to final specification approval. These are commercial terms to verify for each inquiry, not fixed characteristics of the part number.
Choose a supplier that can explain how it reached its fitment recommendation and identify information that still needs confirmation. Ask whether product drawings, specification details or clear assembly photos are available for review. A careful supplier should distinguish confirmed information from assumptions rather than presenting an uncertain match as guaranteed.
For a B2B order, also evaluate response clarity, quotation completeness, packaging information and communication around order changes. Confirm who will be responsible for resolving technical questions before shipment. Keep the final approved specification and supplier correspondence with the purchasing record.
At Shinuo, we handle B2B inquiries for starter assemblies and other drive system parts. To help us review a request for the 10112780 Starter Assy, send the complete number, application details, required quantity and photos of the original component when available. You can also include any cross-reference already provided by another source.
We can review the information supplied, identify details that need clarification and discuss product and commercial requirements before an order is placed. Fitment should remain subject to confirmation against the applicable specifications and application; we do not recommend treating an unverified reference as a guaranteed interchange. Please include your destination market and target timing so we can assess the request in its purchasing context.
The safest way to source a 10112780 Starter Assy is to confirm the original identification, application, electrical rating, mounting dimensions, pinion engagement and terminal arrangement, then validate any cross-reference with supporting information. The part number is a useful starting point, but it cannot by itself establish that every proposed substitute is suitable. Where specifications are missing, request clarification before approving the order.
Your next step is to prepare the part number, equipment and engine details, photos, quantity and any known specifications for supplier review. Send that information to Shinuo for a B2B inquiry, and ask us to identify any open fitment questions alongside the quotation. This gives your purchasing team a clearer basis for evaluating both compatibility and supply terms.
