Why the Same Part Number Ships in Multiple Variants

The base number alone does not guarantee the connector faces the correct direction on your engine build.

Superseded and alternate part numbers — such as the transition from 17531-64010 to 17531-64012 — often reflect internal revisions that change plug orientation or regulator circuitry without altering the mounting flange. I have encountered situations where a Kubota Z482 alternator physically bolted on but the wiring harness fell short because the connector rotated a fraction of a turn between revisions. The machine sat idle while the unit was removed, rewired, and reinstalled. [NEED_CITE: alternator variant identification practices for small-displacement diesel engines] When sourcing a 12V 14A alternator for Kubota Z482 D722 cross reference matching, confirming the exact engine serial prefix and connector layout prevents this avoidable rework.

Fitment Range and Serial Coverage

This alternator covers Kubota Z482 and D722 engines installed in J106-AUS, J108-AUS, and J310-AUS generator sets, as well as the Doosan SOLAR 015 compact excavator. The 12V 14A alternator for Kubota Z482 D722 cross reference group spans machines produced across several generations, meaning the same base part number may appear under different format variations — with or without hyphens, with trailing zeros dropped or retained. Verifying against the engine serial prefix narrows the correct variant and avoids receiving a unit whose mounting flange fits but whose electrical interface does not.

Interface Verification Before Dispatch

The critical checkpoints on this alternator are the mounting flange bolt pattern, the connector pin configuration, and the pulley diameter relative to the existing drive belt geometry. The die-cast aluminum housing maintains a mounting flange tolerance of ±0.1 mm, which keeps the pulley aligned with the crankshaft sheave under continuous vibration. [NEED_CITE: belt drive alignment tolerance standards for auxiliary-driven alternators] Before we ship, we cross-check the plug type — pin count and locking tab position — against the engine build record or a photograph of the original unit. This step catches variant mismatches that part-number-only ordering routinely misses.

Reading the Specification Sheet

The 12V 14A output rating means this alternator sustains adequate charge current for lighting tower and backup generator loads where accessory draw remains moderate. Efficiency above 92% across the 1,500–3,500 RPM band reduces heat buildup inside the housing, which matters in enclosed generator canopies where ambient temperatures already push toward the +70°C upper operating limit. The sealed deep-groove ball bearings carry a 10,000+ hour rating, reducing the likelihood of bearing noise appearing before the next scheduled overhaul. The AEC-Q101 diode standard ensures the rectifier assembly withstands the thermal cycling typical of stop-start generator duty rather than continuous high-speed operation.

The Cost of Installing the Wrong Variant

A mismatched connector forces the technician to either fabricate an adapter harness — introducing a failure point — or remove the alternator, return it, and wait for the correct variant. On a demolition site running temporary power from a Kubota J310-AUS, that second removal can mean an overnight loss of lighting and tool charging. [NEED_CITE: rework cost impact of misidentified replacement components in field service] Even when the machine eventually runs, a pulley diameter that differs by a small margin shifts belt tension outside the intended range, accelerating wear on both the belt and the alternator bearings. Fitment verification before the unit leaves the warehouse eliminates this chain of consequences.

Why Buyers Source This Alternator Through XUNPO

Our Guangzhou facility stocks this alternator with a one-piece minimum order, so a single emergency replacement does not require padding the purchase with unnecessary inventory. Cross-reference verification covers all listed alternate numbers — 17531-64010, 1753164012, and their format variants — mapped against machine model and engine serial data rather than copied from third-party tables. Both our own production lines and qualified sourced supply carry identical QC and warranty terms, so buyers receive consistent quality regardless of which production channel fulfills the order. A sample unit can ship ahead of a fleet-level commitment, giving the workshop a physical fitment check before bulk quantities are released. Our technical team confirms connector type and mounting flange pattern against your machine data before dispatch.

Documentation & Verification

• Commercial invoice listing part number 17531-64012 with cross-reference numbers marked as reference only
• Fitment sheet confirming engine serial range and connector orientation for your specific machine model
• Dimensional inspection record covering mounting flange tolerance and pulley diameter
• Six-month warranty terms document covering manufacturing defects
• Packing photographs showing protective foam placement and carton condition before sealing
• HS code and customs classification support for international alternator shipments

Fitment Check Before Installation

• Compare the replacement alternator connector pin layout against the original unit or engine harness photograph
• Measure mounting flange bolt hole spacing to confirm ±0.1 mm tolerance matches the bracket
• Verify pulley groove profile and diameter align with the existing drive belt specification
• Spin the rotor by hand to confirm bearing smoothness before connecting electrical loads
• If any interface does not match, halt installation and contact us with photographs for variant exchange

Request a Fitment Confirmation

Provide the machine model plate details, engine serial prefix, or clear photographs of the existing alternator — including the connector and mounting flange — so we can verify the correct variant against our cross-reference database. For mixed-fleet inquiries covering both Kubota generators and Doosan excavators, share the full equipment list and we will map each unit to the matching part number.

Frequently Asked Questions

Q: How do I confirm this alternator fits my Kubota or Doosan machine? A: Send us the machine model, engine serial prefix, or a photograph of the existing alternator showing the connector and mounting flange. We cross-check these details against our verified fitment database rather than relying on part-number-only lookups. This confirms the correct variant for your specific engine build before anything ships.

Q: Are 17531-64012 and 17531-64010 interchangeable on the same engine? A: These numbers belong to the same cross-reference group, but interchangeability depends on the engine serial range and production generation. One variant may differ in connector orientation or regulator circuitry. We verify against your engine serial prefix to confirm whether both numbers resolve to the same physical unit for your machine.

Q: What variant differences exist under the same base part number? A: Revisions within this alternator family can involve connector rotation, regulator type, or pulley diameter changes while the mounting flange remains identical. These differences are not always reflected in parts catalogs. We confirm the exact variant by matching your machine model and engine build record to our cross-reference database.

Q: I only have the machine model — can you identify the correct alternator? A: Yes. Provide the machine model such as J106-AUS, J310-AUS, or SOLAR 015, and we will narrow the correct alternator variant from our fitment records. A nameplate photograph or engine serial prefix helps further when the same machine model was built with different engine options across production years.

Q: Can I order a sample to verify fitment before placing a bulk order? A: We supply single-unit samples with the same warranty and QC documentation as bulk orders. Install the sample, confirm connector reach and bolt alignment, and approve fitment before we release the remaining quantity. This eliminates the risk of committing an entire fleet order to an unverified variant.
